[RCSE] Shadow 3
I put my Shadow 3 on sale on e-bay, in case there is any interest. I got it as a gift, but I don't have the synthesized transmitter to go with it. I tried programming it and it worked flawlessly. Seemed to have very good range. Great idea. I do have a few too many RXs now as is. Al RCSE-List facilities provided by Model Airplane News.

[RCSE] Hi-starts
I have been chuckling over the high start mishaps that have been posted after this thread was started. I think that I have seen similar events to many of those reported. I remember one contest where my flying buddy's beautiful 2M Sagitta was dragged to death after a high speed stall on launch. Pieces flew all over the place. If you have seen one of Carl Mohs' planes, you know what an excellent job he does on them. Yes, high starts are unforgiving! I can remember one of the (too many) instances where I launched only to find out the receiver wasn't turned on. On one occasion, my Sagitta 900 did that partial rainbow in the sky until it inexplicably came off of the tow ring on the downward leg. It gained speed in a dive, leveled off at treetop level and headed downwind towards the tree line behind us. There was an awful racket as the balsa and Monokote creation made its way throught the upper tree branches at high speed. It then exited on the other side of the trees...into a weed patch of briars, thistles, nettles, wild raspberries, and high grass. Four of us looked for about 15 minutes before Brian Andreas climbed a tree and looking down spotted it for me. It actually was resurrected and still flies in RES for me now. The one mishap that I haven't seen in this thread was the damage that can be done by stretched monofilament line. In the early days of F3J we were experimenting with light monofilament line (replacing our original braided nylon). In one instance I stretched the line in the usual way before raising the leg to signal release. Just then the line broke and I received a high speed facefull of monofilament and had stripes all over my face for some time. I wonder if those flying F3J have any monofilament stories to contribute.

[RCSE] Vacuum bags
Yesterday I decided to bag the latest version of my DLG. When I got the bag set up I found that it leaked...again. Seems like every time that I start to do some bagging I have to spend an inordinate amount of time to get a non-leaking bag. You know, the kind where you can leave the pump off after pulling the vacuum. Many of you guys (and dolls?) have been to this dance before, I am sure. So, I thought to ask for advice... what you do in this regard? How do you create a never-fail bag? What tricks work for you? I hope that this doesn't start a thread as contentious as the one on the new JR frequency synthesized transmitter modules did. RCSE-List facilities provided by Model Airplane News.

[RCSE] Re: Vacuum Bagging
Mike, that seems to be the consensus: leave the pump running. Unfortunately, my pump is a commercial, continuous duty one that I bought from Grainger. I have discovered that it has one flaw: it sometimes cannot start against an ongoing vacuum of about 1/3 atmosphere or so. I have put together a check valve, a T, and a small leak that seems to solve that problem most of the time. After the pump shuts down, the check valve holds the vacuum in the reservoir, lines, and bag while the leak lets the air return to the pump side. Only problem is that the leak I fabricated is, of necessity, quite small and sometimes seals itself. Maybe I will just replace the pump after all of this advice has been digested. Another consensus is that I should throw away all of the rope caulk, and bag sealing gunk and buy another of those plastic sealing strips...which I will order tonight. I appreciate all of the advice from RCSE writers. It is great to be able able to contact so many experienced modelers through this forum, and hear about their system or procedures. Don't you guys work or something? I cannot keep up answering all of the e-mail that I got on this. BUT ENOUGH, ALREADY! Thanks to you all. Al Michael Lachowski wrote: I leave the Gast pump running.

[RCSE] foam-cutting templates
HOT WIRE FOAM CUTTING WING CORE TEMPLATES. Last year I began cutting wing cores using the CNC approach. As a result I now have a good number of laser-cut hot-wire templates for wing cores that I need to get rid of. I am looking for a new home for them other than Mt. Trashmore. Two sets of one-piece templates are of ply and are for the *E193 and E205* for chords 4 to 13. If you remember, one-piece templates were affixed to the block of foam, and then two people moved the cutting wire through the various stations around the templates. There is a set of ply two-piece templates for the *SD7037* chords from 4 to 14. These are the normal FeatherCut templates for a glass-skinned wing. There is a set of 1/4 ply two-piece templates for the *RG15* in chord lengths of 4,6,8, and 10 plus templates for the *SD7037* in 5 and 8. These are also of the FeatherCut variety and for glass skins. These were designed to cut the top surface of the cores first to reduce the problem of climbing the upper surface hill. There are numerous other templates, some laser cut and some handmade, for a variety of foils and chords. Included are the S4083, RG15, and SD8020. Anybody interested can drop me an e-note. I would like reimbursement for the shipping only. WARNING: 1/4 ply is heavy! RCSE-List facilities provided by Model Airplane News.

Some Eppler 193 and 205, SD 7037 and RG-15. I hate to throw them in the trash, cause there is probably somebody thinking of getting into this aspect of wing fabrication.

Re: [RCSE] Frontside DS?
A comment on DS. It seems to me that years and years ago I found a discussion of dynamic soaring in one of Reichmann's writings. Only in this case the discussion was about full scale soaring pilots who had used a wind gradient at altitude to fly for prolonged periods of time. What is needed is a wind speed gradient and a way to explore that gradient. The first does not need to be slope generated, and the second is a flying technique. - Original Message - From: Ade [EMAIL PROTECTED] To: Brian [EMAIL PROTECTED]; RCSE [EMAIL PROTECTED] Sent: Sunday, November 25, 2001 11:04 AM Subject: RE: [RCSE] Frontside DS?

Fw: [RCSE] Frontside DS?
Last I heard there still was speculation whether the albatross used wind speed gradient or lift from the slope lift provided by the waves or perhaps they are sneaky and use both.

Re: [RCSE] Foam cutting : Further info/help!
Tony, I used to have a lot of problem with that until I finally reasoned that the wire which rests on the template is cooler than the wire that is inside cutting the foam. I made some dummy separator templates out of 1/8 balsa that are slightly smaller than the actual templates and hence will not contact the cutting wires. These then are placed between the foam blank and the actual templates. That way the short bit of cutting wire on the edges of the foam blank passes through air and will be warmer at the edges of the foam blank. I don't know if I needed them with all kinds of templates, but with thick templates or aluminum templates, I found this to be effective. It certainly is easy enough to implement. Try it on a sample and let me know if that helps. I worry about hand guided cutting giving the proper kerf across the entire airfoil. However, that is another can of worms. - Original Message - From: Tony J. O'Hara [EMAIL PROTECTED] To: Soaring List server [EMAIL PROTECTED] Sent: Tuesday, November 20, 2001 5:18 PM Subject: [RCSE] Foam cutting : Further info/help! I want to thank all who responded to my first request. I have simple changed the CompuFoil horizontal ramp to curve as an extension of the leading edge curve. However- I am on a quest to totally eliminate the ridges caused by some remaining twanging: of the wire! I should have mention before that I am using hand feeding/guiding etc of the bow! It's very hard to eliminate the wire twanging as it scrapes over the templates! I haven't achieved it yet! Has anyone? Here is what I have found so far! It's very hard to get wooden templates smooth enough Adding epoxy helps-but not enough Adding graphite helps-but not enough Using other materials such as aluminum or PC board doesn't seem to help enough A test running the wire over a metal tube is best! But I can't figure how to use this practically! Holding the ends of the wire with fingers (ouch!) near the templates helps! But haven't tried it with a cut! Making the pressure of the wire on the template quite low-helps appreciably! So the most significant practical improvement seems to be keeping the weight on the templates low! How can I do this? I am going to try a suspension system and maybe also a gravity auto feed. I have seen some designs on the web but most look much more complex that I think it needs! As I am trying to cut wings for a Xmas gift, I can't afford too much more time. So any further help or ideas would be much appreciated! I am particularly interested in hearing if any one has experimented with wire tension, wire diameter or even a wheel system of guiding the wire/bow over the templates!

[RCSE] Martin SR7 slope soarer
I have a Martin SR-7 slope soarer that I would like to find a home for. The ideal owner would be a slope bug withan old Kraft AM transmitter. The SR-7 is a 55" span aerobatic slope soarer kitted by Bob Martin Models, circa80s.A swept back wingcontributes to the jet-like look with an "unbreakable" molded fuselage of white "Dura-lene" plastic. Wings are plywood sheeted foam cores. Wing area about 588 sqin., and weight about 3#, 10 oz. I could part with it for $125 plus shipping. The condition is structurally sound. It needsa little paintwork, mostlylanding scratches on the bottom, but looks pretty good as-is. It has two servos: currently a Kraft KPS14 for elevator and a Kraft KPS15 for ailerons. Right now it has a Kraft KPR5C AM receiver on channel 12 with a high-side crystal. The servos are good ones, but Kraft no longer is in business and the connectors only fit Kraft. Kraft servoswork well with Airtronics and JR receivers by replacing theservo connectors. This is not a light lift airplane. It flies very well in a medium to heavy wind, and really is spectacular in a gale. I have some jpg pictures. Ifinterested,send me an e-mail.

[RCSE] Dodgson Anthem
I am cleaning out some of the basement and have concluded that I will never get around to building a new wing for my Anthem (Bob Dodgson design). It is complete except for one little thing. I have no wings...the tree won. Wings were obechi covered foam and had the usual four servo set-up for ailerons and flaps. I have the instruction manual and plans as well. The fuse has two Kraft KPS-14II servos grafted to the old style airtronics plugs. That is, the Airtronics wiring is intact. The wing wires attach to the fuse wiring harness with 4 pin polarized Deans connectors. Steel wing rod is good . The fuse damage has been repaired and looks pretty good. With a bit of cosmetics, it could look as good as new. Has anyone out there a need for what I have?. No reasonable offer refused. Try me. RCSE-List facilities provided by Model Airplane News.
