Adding fiberglass/epoxy to the outside of balsa parts to make them durable enough to withstand the wear-and-tear of normal use was standard practice when I started building balsa controlline and R/C models back in the sixties, and probably long before then. My old Falcon 56 had fiberglass tape (lovingly applied with Elmer's glue!) around the center section to keep the wings from changing dihedral in flight, as did most R/C models back then. It is still standard practice today. Any good R/C hobby shop has the necessary materials available for a few bucks, and just about anyone who has the necessary vision, intelligence and coordination to mix epoxy and smear it with a stick can figure out for themselves how to do it. For that matter, what about nylon cloth applied with thin cyano, or Titebond or Elmer's wood glue? It's not fiberglass, yet the results are for all practical purposes the same. It appears to me that some folks are being a little overzealous here, worrying about problems that don't appear to be problems (at least not yet), and splitting hares. Fine if you're making rabbit stew, but not so useful for models. One principle that's worked consistently well for Joe and I is to try it the easiest way first. You can always make it more complicated later. So far, from what's been presented, it doesn't appear that use of exotic materials is a significant problem, at least not yet. Even if someone shows up with a model made from Aerogel with boron/ceramic spars and a digital on-board stabilizing system with GPS navigation option enabled and automatic targeting and homing radar system, it has not been shown that there is any inherent advantage to doing that for this event. If at some point in the future it looks like you MUST have that sort of sophistication to be competitive, you can always implement a rule AT THAT TIME. It does not make sense to make that rule now, because there is no way today, with the experience you have so far, to anticipate the nature of the "exotic technology" problem that may or may not apply to this particular event. It's better to try it without restrictions, see if anything exotic shows up, THEN SEE IF THAT ACTUALLY GIVES IT A SIGNIFICANT ADVANTAGE, and then (and ONLY then) write a rule that stands a decent chance of solving a real (as in "not imaginary") problem. My two cents, for what it's worth. I hope it's helpful, if nothing else for making sure folks have fully thought through what they're actually trying to achieve. Good luck with your event, and I hope the person with the model made from an old cardboard box thoroughly trounces the one with the on-board radar and telemetry system! I've now stuck my nose in someone else's business more than I probably ever should have, so I'm going to take my own advice, shut myself up, and go back to designing some new gliders! ;-) Don Stackhouse @ DJ Aerotech [EMAIL PROTECTED] http://www.bright.net/~djwerks/ RCSE-List facilities provided by Model Airplane News.

[RCSE] Cold F/G
Thank you all very much for such good ideas for helping epoxy cure at cold temps. I will probably be making a box of some sort with all the foam I have saved up from my wing cutting learning phase(ongoing) and use some lights to heat it. Luckily winter has not set in yet and the average garage temp is still 55 to 60 degrees here in Arcata so I have some time to epoxy my tools to the bench w/o the aid of external heat.

[RCSE] RE: Supreme RX
The Supreme is one of the best receivers there is, and at a good price too. Before you glue in, you might consider the Super Slim, same 8 channel dual conversion features, bit smaller package. I have 3 Supremes, one Super Slim, and four 555's. No problems, ever.

[RCSE] Coroplast or balsa tail feathers?
After a couple of years of shelf soaring, I am going to put a Hanger 4 Visionary together. I know, I know its EPS even though EPP is the way to go, but like the bumper stickers on the junky cars say "at least it's paid for" The plane comes with balsa tail parts. Is there any advantage to using coroplast parts instead? Thanks in advance. Roy RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]

[RCSE] Stab & rudder volume
I was checking the formula that was posted on stab & rudder volumes to see how it related to some of the planes that I fly, specifically on one of my hand launches that has a bit of a Dutch roll to it. Sure enough, the rudder seemed to be undersized. I added a lower fin (like a "x" tail) and it flies much better. The formula for the rudder was: .02 = area rudder x tail moment/wing area x span The formula for the stab was: .46 = area stab x tail moment/wing area x mean average chord What was interesting about this was as the tail moment decreases, the area increases. There must be a point where this formula falls apart, however. There must be some nether zone between where the tail moment is short, the stab and rudder area largeand a flying wing. It does work going the other way, ie. the stab and rudder areas of the Logic. Some of the free flight designs don't exactly follow this formula however, especially the high aspect ratio F1A Nordic gliders. Must be more to it than the first run through...

RE: [RCSE] RE: Elevon issues - from the original sender
Nathan put it well. The debate was not of any combat event rules, except the crack about destroying the warbird class. I did see at one time a set of rules used for combat. They must have been just a set of local rules used somewhere. The KISS rules that Nathan refers too have been discussed between me and some others. We do not want the new foamie classes to become that high tech. We want people to use simple materials that will not lead to debate. We want entry level people in there, not expert builders with exotic or expensive materials. Kind of like the Pine Wood Derby was intended to be. These are the kind of rules and spirit of competition I and others want in this series. I nor my friends intend to make Temple Hill Gang change their rules for their events. These rules (not yet formalized or posted anywhere) will apply to the man on man slope racing series that I am getting off the ground here in Southern California. There will be six classes, only three of which are EPP or Foamie classes. I SAY AGAIN, if someone else wants this responsibility I will be glad to step aside and concentrate on sport flying events.
