KR> RE: Magic Carpet Flight
Great info Dan! I love to see KRs with an Autopilot, not sure I'll ever go there myself but good to see all the gadgets working! Rob Schmitt N1852Z From: "Dan Heath" Subject: CorvAircraft> A flight in My Magic Carpet To: "'KRnet'" , "'Corvair engines for homebuilt aircraft'" Message-ID: <000601cdd654$20610ac0$61232040$@net> Content-Type: text/plain; charset="us-ascii" So, now to put the "Magic Carpet" into action, I recently gave the Black Bird a couple of little presents. One was to replace the experiment of the mirror motor trim servo with a Ray Allen and the other was a Dynon autopilot. Since I did not have much experience using this new feature of the Black Bird, I wanted to see what she would do with it. I knew, sort of, how to use the Heading and Altitude features, but so far, GPS Navigation had not been available. So, I went to the Bugs menu and set the Altitude to 4500 and as I was already following the GPS heading fairly well, told it to Sync the heading bug with the current heading. Then I just turned on the HDG and ALT function. Wala! Instant magic carpet. Nothing left to do but to enjoy the ride and monitor everything. The Black Bird was maintaining a heading of 278 and when she reached 4500 feet, leveled off and maintained that altitude. It seemed like magic. A KR2 flying itself, how is that possible?
KR> KR Flying
Boy what a great day for flying! I took 4 young eagles for rides in my KR2S this morning. It was so smooth I let 3 of them fly the airplane - just doing straight and level flight, plus shallow turns. They all did an excellent job! Think it will be easy to get another generation hooked on KR flying with days like this. I then flew down to Pittsburg KS to watch a football game with my daughter who is attending college there. Pretty good day - except the Pitt State Gorillas got killed on the football field. About 3.5 hours total flying today. Rob Schmitt N1852Z _www.robert7721.com_ (http://www.robert7721.com)

KR> RE: 2300 Propellor
Concur on calling Joe, and or Ed Sterba. I've got a Revmaster 2100, but I don't know of anyone running the 2300 on a KR. I could be mistaken. My prop diameter and pitch is 54" x 54" using on a trigear. Prop by Ed Sterba. 52" is common as well but not over 54 to keep tip speed below the magic numbers. My cruse speed is 130 mph at 3000 rpm.

KR> Re:VW enough for 2
Brad, In a KR size does matter. The answer is yes if they can fit height and width wise. I've flown with two on board regularly and even fly Young Eagles. It starts getting cramped though if the passenger is over 5-10' and 200 pounds in my airplane. My max allowable pilot and passenger is 370 to stay in CG. I weight 170. My canopy was designed for my height (5'-5"), and width was increase from stock but only about 2". That being said I flew my 100 pound mother to Oshkosh with full baggage compartment - no problems.

KR> RE Diehl Gear Conversions
Dave, Sorry, I'm slow to comment on this one but I think important. Before you move the gear mounts out too far from the fueselage sides, consider whether or not you will be trailering the plane often and the width required. I think the normal width allowed on the roads is 8' so I would not bust that if your 're going to be hauling it around. But since you are in the military, I think you might be. I pushed mine out just a couple of inches from the sides, and ended up making a special trailer just to haul it to the airport and back. I could not find a rental trailer that would work.

KR> RE Build Hours
I spent 1500 hours over 8 years building (would have been 5 except for two military deployments). I documented the building time on a log as I went so I'm very confident in the hours. Mine is pretty simple and close to plans, not many modifications. Pretty simple interior, no flaps, and I purchased and installed a used VW engine. Single fuel tank in the header. Things that added more time was that I scratch built the wings, aft deck and front deck. Cowling was purchased from RR. Paint job I did myself (and it shows). She flies great and has been tons of fun. Flew again Friday night, Saturday the rain keep me on the ground.

KR> Re: Flight Test Plans
I meant to add a couple of thoughts. I found it pretty difficult to write down all the parameters and times during flight tests and such. It was big help to use a video camera pointed at the instrument panel with the date/time stamp running. That way I could go back and confirm time to climb/indicated air speeds etc. I can get pretty exciting flying an airplane in the test phase. The camera meant I could concentrate on flying. I had no issues with this plan presented to the DAR. I also had just a 1 sheet summary page I presented to him as well. It just listed the basics for the plan in 10 hour blocks, i.e. 10 hours Initial flight stability tests/ 20 hours - Cruise testing/stall testing/climb testing, 10 hours - weight and balance testing. Something like that if I recall correctly. I think that was what he really wanted, and not the extended test plan. Thanks, Rob In a message dated 2/25/2012 11:06:08 A.M.

KR> RE Pitot Static Port
Todd, My ASI acted similar to yours one day, it turned out to be a split in the pneumatic tubing developing near the instrument. It was very disconcerting but I also had the GPS running so I knew I had a major error. For the most part my ASI/VSI reading have been good. My pitot and static ports are on the left stub wing - underneath out at the end of the stub. I do get a slight dip in the VSI as I start a climb before it starts to give a positive climb reading, but other than that my ASI has been generally true within a couple mph.

I need to move mine, as I currently have two choices, one inside the cockpit which causes the ASI to read about 30 mph fast at cruise, or one on the wing which will actually let me slow down to zero indicated prior to reaching a stall. Neither of these is acceptable to me, so I am going to put one in the side of the fuselage and try that. A foot aft of the firewall sounds about right, but has anyone come up with a more exact measurement for the ideal spot? Todd Thelin Spanaway, WA
KR> RE: Aeropoxy
Joe, I used Aeropoxy on my wings, I used the gallon kit if I recall correctly. I recommend making up the epoxy in small batches as you move along, not a large pot - it will cook off. Aeropoxy comes with set mix ratio, I used a set of West System pumps which matched the required ratio. I took the Aeropoxy resin and hardener and put it in containers that the West pumps would mate to without problems. This simplified things greatly and made for a way of mixing batches quickly.

As before, my concern is vapor lock, so I'm always interested to hear from others about how they've mitigated this one.

KR> Home from Oshkosh
I flew N1852Z home from Oshkosh Saturday to Kansas City. I had a great
time as usual and it was good to see all the KR folks at the forum Monday, at
Bob Gliddens cookout at Found-du-lac, and Larry's campout in Camp Scholar.
Got to hang out at Larry's with Joe H, Mark L, Josh and Channel for some
oddly named but great tasting beer ("Goats Head" I think it was called - flown
in by Joe). Several others were at Bob's cookout as well including Mark
Jones. Great hospitality by all and good times.
I think every time I stopped by my KR during the week, someone would come
up to me and say hello and ask questions. Talked to lots of folk and
encouraged them to make it to the Gathering in Sep to see more KRs up close.
I spent most of my week sitting in forums by Bob Hoover, Chuck Yeager, Burt
Rutan, Dick Rutan, and Bud Anderson. Seemed to me these folks are our
nations greatest aviation heroes and who knows how long some of them will be
with us still. During previous years I had spent most of my time in the
builders forums, which are excellent as well.
The KR2S performed great, I know it is just a VW engine in mine, but it is
well qualified to fly-into and out of Oshkosh. I always get a kick out of
the flying in and out. To be honest this was my easiest year flying in. I
came in at approx 800 am on Sunday and only had one Bonanza ahead of me, and
a Davis DA2 behind. Not a lot of pressure compared with previous Sunday
arrivals. It fact I nailed the "Yellow" dot on 36L this time. I think I
overshot my touchdown every year previously. Leaving Oshkosh was even easier.
l
left at 700 on Saturday and taxied straight to end of 36 and got immediate
clearance to take off - no waiting line this time.

I went flying again this morning with our "Breakfast Club" and I really enjoy flying this great little airplane. When I tell folks I built it for less than $15K, most people are stunned - they have drank the RV Koolaid and don't believe it can be done for what we in the KR community are investing.

I bought new replacement valves from Revmaster and new springs. I gave it all to a Cylinder Head shop here in Kansas City and had them do the work. They replaced the exhaust valves and cleaned everything up to include regrind on the seats. All told about $200. Pretty routine requirement for a VW engine, per the folks from Great Plains and Revmaster. I flew again this morning with the EAA 91 Chapter breakfast club.

Subject: KR> Alternator Wiring
Dave, I can not answer your question directly, but I did have the same problem. I recommend you put a lock (key or cover) on your master power switch prevent it from turning off while the engine/alternator is running. When the turn off master when the alternator is generating you get a voltage surge that can kills devices, even if there is a cb/fuse between them. Same happened to me. I fried two pwr supplies/cords for handheld gps that way. 1st of all never kill the master while devices are running on the alternator. Second, do something to prevent the master from turning off (even accidentally). If you feel the need to turn off the alternator while running, turn off all other devices 1st. I looked at surge suppression devices, but didn't like the prices. I do have a wiring diagram of my system. It is in the POH on my web page.

On a test run, I killed the master switch, but the panel didn't completely shutdown. Upon investigation, I discovered that the alternator was powering the panel, and it cost me a radio in the process. Hence, the relay. However, I think the accepted practice is to switch the field instead of using a relay on the output. So the really stupid question is "How do I ID the field?" Is it that jumper on the connector at the voltage regulator? Thanks! Dave.
KR> RE: Charging System
Jim, I have a Revmaster and use just a voltmeter. I get 14.1 volts when nothing else is running. When I turn on the lights/stobes/landing light it drops to 12 volts. Sounds like the volt regulator needs replacement, but I'd call Joe Horvath at Revmaster and discuss with him. He is very helpful.

KR> Update KR2S N1852Z
Thought I'd send an update on my plane since I've made a few changes lately and had some maintenance done on her as well. I passed the 250 hours mark on N1852Z and she is ready for another trip to Oshkosh and the KR Gathering this year. This spring I installed a Dynon D6 in the cockpit. I have added a short video of the instrument panel and some flying to my web page at _www.robert7721.com_ (http://www.robert7721.com) if anyone is interested. The D6 was a very tight fit and I was not able to use the regular wiring harness. I made my own connections and I have only the power and ground wires installed to the unit along with Pitot and Static inputs. The D6 does not have an internal compass, it requires an external unit and I do not have that hooked up right now. I have plenty of other directional information from my magnetic compass and GPS. I also did some engine work on my VW Revmaster engine. My problem started out as a loss in RPM (about 200) that I could not quite determine on a flight. I checked valve clearances, spark plugs, etc. This were all fine so I then pulled the heads. Both heads had cracks in between the center valves developing - I did some checking and this is actually fairly normal for VW heads. I had the heads reconditioned by a local machine shop in Kansas City. They said I also had two burnt exhaust valves and needed new springs. I called Revmaster and Joe Horvath sent me the parts - cost was less than $60. The cylinder head shop re-welded the cracks in the heads, reworked the seats, installed the new exhaust valves for about $120. All told less than $200 to repair the cylinder heads. It only took me about 2 hours to remove the heads, but probably 3 to reinstall everything. All told I was out of the air for about 4 weeks. I've been flying again for a couple weeks and yes, everything is back to normal. This has probably been my most expensive repair on my KR since it started flying in 2006, I'm pretty happy about that. It was more depressing to not be able to fly for about a month. I plan to be at Oshkosh in the Homebuilt Camping this year. Hope to see a few other KRs there as well. Should be flying in on Sunday morning. Probably be there till Friday or Saturday. On a separate note, Terry Chizek (KR2) is having his annual fish fry and BBQ again at his airport in Marion Kansas (43K) this summer, so if you are in the area please drop in. Date is going to be Saturday 21 August. Rob Schmitt N1852Z Kansas City
KR> RE: Tubular wing tanks
Ron, Bill Clapp has the PVC tubes in his wing tanks. Not sure it was irrigation tubing. Pretty sure Bill just used PVC and it looked like 2 each 3 " tubes. Should be able to find pictures and details of it somewhere on Mark Langford's site on one of the KR Gathering photos collections. Probably 2004 or 2005.

KR> N1852Z returns to the air
Jeff Scott sent me a note asking if I was back, so I figured I would let everyone know I'm finally home from my latest military deployment to Iraq and that my KR2S is back in the air. But I didn't get home until last Tuesday the 29 of Sep, so I've missed two KR Gatherings in a row, and yes I was bummed. I've stayed on the KR Digest and I did see where "Old Blue" and the one other plane crashed, very sad news but good to see Dan is recovering well. Just this week I managed to get N1852Z back in the air. I had to replace the entire exhaust system due to corrosion and age. I bought a few tubes from Steve Bennett welded it myself. Yesterday was her 1st real flight in over a year after a thorough Annual Inspection. She was happy to see air under her wings again and so was I. Deployment went very well. Things in Iraq are in much better shape than my deployment in 2005. The Surge did a good job of cleaning out the bad guys, and the Iraqi Security Forces are now in charge in all the cities. While it will never be perfect, the violence levels are pretty low compared with previous years. I'm taking a month vacation before I head back to work at my engineering job. I dropped by there yesterday and it looks like no issues with going back. The economy has caused some layoffs, but my job was held for me.

KR> RE Magellan 315A
Mark, Sorry to say, it is probably the begining of the end for you poor 315A. I had the exact same model and did all the downloads you had recommended on the web for the aviation database. One day it started to do strange things. The whole sattelite screen went blank one day while flying. But it started working again a few days latter.? Then at the 2006 KR Gathering, it started to take 30+ minutes to get sattelite lock - even out in the open far away from any interference.? It tried reloading the filmware for the 315A and that seemed to work for a while. I moved the 315A farther away from the hand held radio. Then one day it fiallly just went blank. I used another cheap Magellan for a while (Sport Track) which I was able to figure out how to transfer the same airport database information to, but only 500 waypoints. I just recently bought a Garmin 96.

I've gotten work some work done on my KR2S during the winter and I will be getting it back out to the airport this weekend (weather permitting). I painted her and added lights so I can operate at night. Paint was just a gloss white boat enamel. I painted her using a harbor freight air sprayer and borrowed air compressor from the EAA chapter. I did not get the wheel pants/fairings done as I had planned for this winter. Problem is I keep reading the flying reports from everyone and decided I just have to get back up in the air. Also since it is Friday. A friend at the chapter here in Kansas City has a Zenith 701 project for sale for $24K. It is almost finished with maybe 6 months of work left in it. If your looking for a project that would not require a lot of time to finish it up this would be a good one.

KR> Great Plains Strobe Kit
I saw some discussion on the Great Plains strobes this past week. I'm on the digest and don't catch up on my reading very quickly. So sorry if this is late. I purchased two Great Plains Strobe kits and didn?t have any trouble getting them to work. I?ve added a new page to my web site at _www.robert7721.com_ (http://www.robert7721.com/) to show how I did it. I assembled both kits then installed them into a Radio Shack ?Project Box?. The only thing I remember doing different was regarding the Blue Trigger Coil (T3). I did not like the flimsy wire on it, so when I mounted it to the bread board I mounted it in a bed of epoxy to make sure it was secure. Both kits worked on the 1st try, so I guess I didn?t have to do anything that unusual. My strobes are still not mounted in the airplane just yet. I am currently working on the landing light installation. Rob Schmitt _robert7721@aol.com_ (mailto:robert7...@aol.com) KR2S N1852Z Kansas City, MO
KR> RE: RC Servo
Larry, Jeff is pretty close to what the DAR said. The RC servo does needs power to hold position. The DAR stated that if it lost power it would not remain fixed in place and therefore would potentially cause flutter in the elevator - therefore unsafe. Right now I only have a ground adjustable trim tab on the elevator. When I fly two people, I definitely have to hold forward pressure on the stick. Since I've already got the servo, I'm looking at trying to figure out how to use the RC servo to control a trim spring inside the cockpit on the control stick instead. Shouldn't be any problem there if I lose power.

The Ray Allen Trim Servo unit use a gear drive from a small electric motor that locks where it's at when the voltage is removed. I suspect that Dan's Sable mirror motor is very similar. A RC servo has to have voltage to hold a position. The heavier the load against it, the more amps it needs to pull and the more likely it is to fail. If I found an RC servo in the trim on a Tech Counselor inspection, I would advise the builder to remove it. If I found it on a condition inspection, it would have to be removed before it gets a signature in the logs. The DAR was right on the money with his recommendation. Jeff Scott A&P
KR> RE: Header tank
Reference the header tank vs wing tank discussion. Just like most things on the KR, there are many ways to do things. My KR2S has just a header tank with approx 16 gallons. My reason not to put fuel in the wings was complexity. I simply didn't want to add a fuel pump and tanks to the wings. The 16 gallons gives me 3 hours of flight time with reserves. I have plenty of range for what I desired to build the airplane for - local fun flying. My fuel tank is integral to the forward deck and is removable by mounting screws that are attached to the sides/firewall/and near the instrument panel. My CG is calculated so I know that my fuel causes the CG to move approx 1.6 inches as the fuel is burned off. I can still carry a 220 passenger and stay within the rear CG limit, I weigh 160 pounds.

KR> Wheel pant Ideas
Chris, I found out that there really are no absolute answers on how to do it. Most folks buy wheel pants from a variety of different suppliers. Aircraft Spruce is just one of them. Some folks get one pant/fairing and make molds and copies of them themselves for the other legs. Some people make them completely from scratch. They can be split vertically or horizontally or not at all. The inside wheel fairings (that cover the brakes) are all made from scratch. Steve Glover showed us a relatively easy way to make them using ordinary window screen. You hot glue to screen to the leg, wheel, etc to get the form, then fiberglass over it. Glenda's web site has some good photos of Steve's method on her site.

KR> RE: KR New Photos
Mark, Good to see you are home and all in one piece. I always have had concerns about what would happen if I got stuck someplace remote and not knowing anyone. It is great to see these folks just practiaclly gave you the shirt and "trailer" right off their back. Cool! My trip home was uneventful. I ran the Revmaster at 3200 rpm and ended up getting fuel enroute which I wasn't quite expecting but not a big deal. The previous Thursday I had made it to Mount Vernon easily running at 3000 RPM and still had plenty of fuel left (12 gallons burned out of 16 in the tank). I landed in Warrenburg MO (9K4), home of Central Missouri State University. Turned out all the kids running the FBO on the weeked are in college working on their aviation degrees. Great to talk to them for a while while the plane was fueling up. I got lots of great ideas at the gathering on wheel pants, legs pants (Steve Glover), paint and such. Loved it as usual. Even better flying my plane there for the 1st time.

Jeff, Sorry I'm slow to respond. I've been flying my airplane this weekend quite a bit to get the 40 hours completed, and I've got it done. Looks good for a Thursday departure for me as well. I expect to depart KC around 1:00 pm and will be monitoring 123.45 once airborne. See you Thursday.

KR> Flight testing wrap up N1852Z
I've completed all major items on the test cards for my planned Phase I testing. There are some items I did not complete, but I was not thinking of ever doing serious aerobatics in my airplane so I passed on some of the more rigorous aircraft testing such as accelerated stalls at high bank angles. I did no spin testing. Some items of note; I rechecked my climb rate at 90 mph (I had gotten bogus data on a prior test), re-zeroed my UMA VSI and am getting better results. Final analysis is that 80 mph looks like my best climb rate right at 800 fpm. I can get 650-700 fpm at 90 mph IAS. I did a lot of cruise testing at different altitudes and now can successfully lean the mixture as required for smoothing out the engine roughness to get better fuel economy. The Revflow carb is not instantaneous in its adjustment, but I'm getting familiar with just where I need to put the mixture to smooth it. My EGT is the best indicator of good leaning along with the sound. My current mixture set point seems to be just about right. I'm not inclined to change anything since everything is working fine. I pulled the upper plugs once during flight testing and only #4 looked like it might be getting some carbon fouling. Mag checks are good on the ground during runups and while I get an RPM drop, I do not feel or sense any roughness. I did an oil change and found no metal particles in the oil. Oil filter looked good as well. Engine normal cruise running is 275 CHT, 140-160 Oil temp. approx 1200 EGT. I have not been pushing the engine at redline 3400. I am running it between 3000 to 3200 rpm and feel comfortable with those settings. This gets me 120 mph on the cruise speed at 6500 feet. Best speed I've seen WOT is 140 mph at 2000 feet. The final testing I did was to add weight to simulate a passenger. I definitely kept full fuel level in the header tank and rechecked the weight and balance to make sure there were no issues. All went well. I did a 90 pound load 1st and then a 170 pound load. The aircraft still performed extremely well and was controllable in aspects. I found no unusual new pitch sensitivity. VSI says I am still getting 500-600 fpm with the simulated passenger so my performance is still good with two on board. I did have a couple of botched landings during the weekend. The winds were 10+ gusting to 20. The wind was pretty much down the runway but because of the light wing loading I got pushed around a little. I made one major mistake that I always got by with in Cessna's, typically when windy I have deliberately flown the aircraft on to the runway above stall speed to get her down. Well I tried that and a gust of wind decided to put me back up and away since I wasn't at or below stall speed. I gunned the engine and got it back up in the air quickly and went around. On the second try I paid better attention to my airspeed and made sure I didn't touch down until I had bled all the speed off and made a good landing that time. Lesson learned. Squawks. Several in the past couple weeks. I've always kept her flying but have spent more time than anticipated on maintenance (typical of the entire building process). I had a heel brake push plate rotate off the master cylinder rod during flight due to vibration (These are the heel brakes from Great Planes). When I landed I found my heel was pushing on the rod with no plate. I was still was able to stop and control it. I used lock tight on the plates and will make sure to check them from now on the preflight. I also have changed my fiberglass seat bottom out as the top side had started to delaminate. I have a sheet metal seat bottom now. She's not pretty but she flys. See you all at the gathering. Rob Schmitt N1852Z
KR> RE: Trim indicators
Phillip, I've got a servo motor doing my elevator trim. I used a (Radio Shack) rotary potentiometer for the control (less than $5). I made a larger wheel for the pot out of plywood, painted it black, turned it sideways and put it in the instrument dash (lower left side in front of pilot). I just recently put a white tick mark on the wheel at the center position for trim. I do have pictures on my web site www.robert7721.com under instrument panel.

KR> RE: Trim indicators
Larry, Servo motor came from "Hobby Town" it is a HITEC HS-300. Size 1.6 x .8 x 1.4". Plywood thickness was 1/4". I did build a small electronic control board for the management of the servo, but have lost the skematic since. Probably could find another copy on the web if necessary. It was not difficult to built. The servo uses 5 Volt power, I used a Radiio Shack volt regulator and tied the power into my 12 volt system. So far works great on the ground with plenty of sensitivity for control of the trim tab.

KR>KR2S Belly Crossmember
I installed belly cross member at station E only. No issues with this on my KR2S. I doubt it would make a large difference whether you have one at D and E. A little bit more work to install the floor insulation between the members before you cover it with plywood. Rob Schmitt ---Original Message--- Subject: KR>Question for the group I am dry fitting the belly cross members prior to gluing and have hit a road block (with which I am hoping you all can help me); * My original KR2 plans (dated 10/08/86) show a belly cross member at station "D" only . * Drawing "A" (of my new KR2S supplement..Sept/92...just received) shows a belly cross member at station "E" only. * I looked at Mark Langford's web site and it looks like he installed 1 cross member is located at station "E" only. I was wondering what the downside would be to installing a belly cross member at BOTH "D" and "E". Mark's fuselage looks so good I should probably stick with station "E" only...any ideas or comments? Thanks for your help...I'm really getting energized after a 15 year hiatus from this projectI'm assuming all the spruce I bought in 1986 is still safe to use. I'd sure hate to buy all that wood again!

KR>Fiberglass
Gav, You had also asked a question on how much epoxy to buy. I ended up using 4-5 gallons of epoxy, but I am also scratch building all the way. I bought a gallon at a time as I needed it, not all at once, and bought the next gallon as it was getting low. That way you don't have epoxy sitting on your self for several years. Some epoxy does have usage dates. I've used West, T-88, Aeropoxy, and the dreaded vinyl-ester for the fuel tank.
