[RCSE] Some thoughts on Wood Construction and our contest...
I received a question of eligibility about the Ava sailplane. I have never seen one so I don't know about it's construction. Primarily of concern are the D-Tubes in the wing. Are they molded, or are they ribbed and sheeted like the Bubble Dancer? In my opinion, the Bubble Dancer is about the epitome of built-up sailplanes. They will be welcome, unless they are bagged, or contain any bagged parts. I've seen some with bagged center sections, and built-up outers. I will not allow any sailplanes with foam or molded wing / tail parts, other than a molded fin on a fiberglass fuselage. Some of the European stuff with molded D-Tube and balsa rib construction is really nice, but doesn't fit with the spirit of what's being fostered by the woody movement. I want this to get to all interested parties because I don't want someone to show up with something, expecting to get to fly, and be turned away. That would ruin my day, as well as theirs. Anyone with direct knowledge of the Ava, please respond off the board, so I can make an intelligent decision...(there's a first time for everything, you know!)

Neat plane and great accomplishment. Even though the move from NH to SD wiped out your workshop, you get a lot more sun to power your plane, so that's the tradeoff. __ Do you Yahoo!? SBC Yahoo!

Ah, Jack, if you saw an Ava you'd weep in envy, in esthetic appreciation, and in the knowledge that balsa could never be this good. The D-tubes appear to have ribs inside, but they are free-flight construction, i.e. they are sheeted with carbon fabric that is laid up inside a pre-machined mold. The ribs are made by taking thick balsa, maybe 1", capping it with carbon, and then slicing them to about 1.5 mm thick with some sort of special slicing machine. The t.e. is a strip of carbon about .025 thick and about 1/4" wide. It is fitted into a little slot at the t.e. of each rib. The covering is put on in one piece, top & bottom. It's fastened to the bottom of the spar, wrapped around the t.e., then back to the top of the spar, and shrunk in an oven. There are no seams in the covering. I kid you not. All in all, it's a masterpiece of built-up construction, like a modern Wakefield or A-2. But a woody it ain't. Its wings are 8.7% thick and can easily take a full pedal launch and zoom. Mine weighs 38 oz; this is for a plane with nearly 1100 squares. It uses a Drela composite airfoil, not the flat-bottom AG35 used on the BD. Its penetration ain't bad for winds up to maybe 8-9 knots, and after that there's always ballast. The huge mono-spoiler and large dihedral provide unusual landing characteristics for a big RES. And of course, it thermals like any 127" HLG would be expected to. As to whether or not to make it eligible, that's your call. But I know you're a lover of beautiful planes and elegant design, and this plane exemplifies a lot of cool stuff. It's true that real men scratch build. But to make the molds and jigs required to build this plane is really out of the realm of the average guy's workshop and time commitment. So find somebody who has one and check it out, or send your money to Barry [EMAIL PROTECTED] and become a happy Ava owner. __ Do you Yahoo!? SBC Yahoo!

[RCSE] Re: DLG flying wings, help me choose...
Trying to decide between a Red Herring, The Gadget, and the Mosquito. I'm a big flying wing fan, what can I say. I like EPP, I have to run on the cheap side, so HS-55's are kind of my speed for servos, plugged into an old Cox Cobra 2/3 ch. AM system, with a tiny electronic elevon mixer added to the flight pack. Cost is a factor, as is fun for money spent. I have built and flown some 2-meters, but am not a big expert on composites or high-end radios, and would prefer one that's easy to build right. This will be my first DLG, it will travel in my trunk a lot and probably take a lot of wear and tear during the learning curve. What says the collective soaring gestalt?;-) Recommendations for batteries, too? RCSE-List facilities provided by Model Airplane News.
