Re: [RCSE] 555 vs Super Slim 8
Also how is the general performance of the SS for TD work? Long range as opposed to HL or slope work. All my experiences have been good but have not used it in thermal ships as of yet. I had one in my 2m delta wing and I specked it out to probably around 1500ft. and over 1/2 mile down range, 11.5sq. ft. of wing area is visible from a long way and this was just a speck, range isn't an issue with the slim 8.

Gordy Fred Marks may think he is going to do a IPD receiver. It may take him quite some time to do it the same as Multiplex. Just goes to show you, A) Fred sees a great idea and has to steel it. B)Hecan only copy not create. C) Just as you point out he does not know how the stuff is used. Smooth Sailing,Karlton Spindlehttp://www.MultiplexRC.com
[RCSE] Hand Cat Update
Hi, Guys: For those of you who are interested, I just finished the P2 prototype Hand Cat, EPP hand launch glider. I've posted 4 photos on the "coming soon" page of my web site for review: http://www.rc-aero.com/spy.html I managed to get out and toss the model a couple of time this evening even though the winds and temperatures were both not very conducive to test flying. I need to tame down the elevator throw a bunch, but already I can see that the revised P2 launches higher and penetrates better than the original P1, and it also seems more responsive. The design goal for the Hand Cat is to be not only a great plane for sport flying, but to also be the ultimate back up ship for contests-the plane you can count on to be there and fly still fly competitively. Specs on the new P2: Wingspan: 59 inches Wing area: 265.5 sq. inches (1.84 sq ft) Wing loading: 5.5 ounces/sq. ft. Airfoil: blended section from root to tip, modified Selig 3000 series. Washout: 1 degree at tip All up weight: 10.1 ounces Design features of note: Integrated throwing pad Composite EPP foam/balsa/carbon construction Bolt down wing Swept forward V-tail The fuselage as seen on the web page is an interim item. The P3 fuselage will be production intent and will implement a canopy for accessing all components. I welcome any questions or comments. Assuming I can get some air time for test flying, the Hand Cat could be in production as soon as the end of the month.

[RCSE] antenna/carbon boom ?
I know this has been discussed before but I've never owned one and didn't pay any attention. What's the best way to route the antenna down a carbon boom to keep out any interference ? It's on a hlg.

Re: [RCSE] Kevlar Questions
I use Kevlar for my HLG fuse with great success. I just bought a second batch of cloth and noticed that the old scraps left over are a couple shades darker than the new kevlar. This is, as I've read, because of breakdown somewhere at the molecular level. I've also heard that a layer or two of fiber glass is supposed to prevent this breakdown. Along another thread-line... I found a source of Kevlar tonight in my basement. I teach percussion and have for years. During the Fall, I work with marching bands. High-tension snare heads are now (for the past 13 years) made from woven Kevlar. I had a bunch of old heads in the basement that we had replaced at the start of a season with a University drumline. I cut out the woven kevlar and peeled away the plastic top surface. Nice and lite...and free. Of course, the pieces are just 14" round.

Re: [RCSE] antenna/carbon boom ?
I use magnet wire, wrapped on the outside of the boom, secured with single wraps of #600 tape every 8" or so.

[RCSE] Airfoil: Learjet (saac)model 23
Hi all, Does anyone have a reference to find out what airfoil was used on the Lear jet model 23 ? My local libraries don't have the Jane's book for that year (66 or 68, I believe)That the aircraft was rolled off the line. Thanks, Jim
[RCSE] Re: MH32/low wingloading myths
I just checked my email after many days away and the posts about MH32 airfoils caught my interest as I too have thought about using that airfoil. I noticed one post wanted the "myth" about lightweight planes flying better addressed. In some conditions I think a light weight plane does fly better than a heavier/higher wing loading plane. Yes I have heard from many that weight isn't that important; or light weight planes lose any advantage they have during launch as the heavier plane will launch 200 ft higher, thereby negating any advantage a lighter plane has; etc.,etc.. Yet if you were really scratching for lift in light conditions, running out of altitude- which plane would you prefer? I dont know much about aerodynamics, but I know from my experiences it seems in light, low level conditions a light weight plane will out climb a heavier one. This has been proved to me time and again this past year. I am not a very good flier but have many times come into a gaggle of high tech moldies in lighter/low level conditions w/my light weight plane(Mantis) and have flown thru and topped out above them. As I said earlier, this certainly wasn't due to better flying skills as mine arent that good. I have to believe it was due to the lighter weight/wing loading of the plane. I am a firm believer that you can make a light plane heavier(ballast) but you sure cant make a heavy plane lighter.

Re: [RCSE] antenna/carbon boom ?
I would do it this way. Let at least 6" trailing in free space, I run it through the boom and the extra length loose wind on a foam size that can just fit into the compartment. (too small foam can detune antenna). HLG condition. I second the full winding on tail boom for tail heavy and excessive counter nose weight reason.

[RCSE] Re: Histarts
Other component options: Line: I'd recommend 40 pound test monofilament fishing line. You don't need the strength, but it's less prone to tangle than the lighter stuff. It also doesn't twist due to tension. Hi-start seamless rings: Go to pet store, buy two choke chains for small dogs, cut or bend off the chains, you end up with 4 small seamless rings. Small seamless rings are hard to find in hardware stores. Hi-start winder: electrical cord winder, available at department and hardwares stores. These are usually orange. Chutes: dynaflite chute is strong enough, but I usually make a minor mod: thread a small piece of string just under the top of the chute, then loop and tie this string around the tow ring. This keeps the chute closed tightly when there is tension in the line. The dynaflite chute, when unmodified, has a tendency to pull through the two lines that loop around the tow ring, and won't completely close with tension (after a few sessions). Stake, a pet type coil stake (15 inches) for semi-soft ground, a straight stake for hard ground. In my case, I bought a small dynaflite hi-start kit, dumped the string, and the small winder. I used the tubing, stake, and chute from the kit, and bought more tubing, rings and fishing line, and cord winder as described above. Histart setup: I use 3.5 to 1 ratio for line to tubing ratio. I pull back 3 to 3.5 times the length of the tubing (assuming it's the standard latex (including Hollyday) tubing. To attach tubing to ring, make a half loop, slide through and then back over ring to make a square knot. If there a line or other tubing on the ring, pull a loop of the attached line through the ring, thread the new tubing through the loop you just created, then pull the old loop back, creating a loop with the new tubing, and pull the new loop back over ring to form square know. To tie fishing line to ring I use the uni-knot with 7 or 8 turns, as described at: http://www.stripersurf.com/andeknots.html RCSE-List facilities provided by Model Airplane News.

[RCSE] antenna/carbon boom ?
After dealing with some glitching in a couple sailplanes, I had my transmitter tested by George Steiner. He used this computerized whizbang gizmo in his den/lab to test it. The thing took forever to boot up, and we had an oportunity to talk for awhile about receiver antenna placement lore, always a favorite subject here on RCSE. Bottom line: whatever the heck works is what you should use. Use a range test (collapsed TX antenna, walk back at least 50 feet, the further you go without servo jitters the better) as the true test of the best antenna arrangement. With that in mind, I snipped the antenna wire from a Hitec 555 RX in my Spectre HLG, and attached the stub to both of the 0.015" music wire ruddervator pushrods that go through plastic guides in the carbon tail boom. Grams gone, clean, outstanding range. Rob Crockett Grass Valley, CA RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
