Re: [RCSE] AVA vs Bubble Dancer - Buy vs. Build
Well, I don't know the exact definition of woody, but the Ava's wing and tail surfaces are primarily wood with carbon reinforcement. Unless that d-tube doesn't have any sheeting under it, and I'm not submitting mine for surgery. (hmm.., it's unpleasant but I could dig out those smashed tips and look at the inner panels). What the Ava most definitely is NOT is an EXACT copy of a Bubble Dancer, although certainly there is a high level of imitation. I suspect that if you could measure precisely enough, you would find that Mark's Bubble Dancer (as built by Mark) has performance numbers a little bit better than those of the Ava. For one thing, the "foil" shape on the tail is very different. Plus, the Bubble Dancer's tips have d-tube sheeting and the Ava's do not. (I have heard (or perhaps read?) Mark comment on the performance penalty of not sheeting tips a number of times.) Structurally, if I recall correctly the sheeting on the Bubble Dancer is just wood, while there's carbon-kevlar cloth on the outside of the Ava's d-tube. Also, I think the Bubble Dancer uses hefty wood ribs and substantial wood trailing edge where the Ava uses skinny wood with carbon cap strips. Hence the infamous picture of the buckling Ava t.e. on landing. I can tell you that it seems sturdy when it's in one piece but it kind! of crumbles when you break it. Which is ok if you're just going to buy replacement parts. The Ava is built to a high level of workmanship, and I think you'd have to build a Bubble Dancer to nearly the same level if you wanted to exceed the Ava's performance. On the other hand, I think the Ava is close enough that you shouldn't feel handicapped or use it for excuses. It flies very well. Using it for my LSF hour flight felt like cheating.

[RCSE] Re: WTB AVA
I know you weren't asking me, but I am going to try splitting the spoilers on mine. I find that with the one big spoiler, the pitch changes are extreme, and if enough compensation is used the initial pitch up is really annoying. I didn't learn how to land it well before I busted it, but it sure flew well. I laid up a larger ballast tube out of some carbon I had lying around. I'm sure fiberglass would make a fine tube as well. I think the tow hook as supplied, as with most RC gliders, is bigger and heavier than it has to be. But then, I drive a Saturn instead of an SUV... I just glued in a block of wood and screwed in my standard bent cup hook towhook. You may need to work on the joiners and their boxes a little bit to get the wings to assemble well. Sand them or something, but carefully, with a block of some sort. That's all I remember right now.

Re: [RCSE] "YOU can break Carbon rod for stab
You are such an idiot that I feel it necessary to demonstrate. Therefore please make up such a rod which will fit my Chicago Style and I will test it thoroughly until it breaks. While you're at it, could you make a spare? Thanks!;-) More seriously, in the larger sizes, where the brass wall isn't so thick, that's probably a good idea. Bill Wingstedt wrote: I had to put a carbon rod into service as a stab axle once. All I had was one of insufficient diameter. Luckily, I had a piece of brass tubing that it fit into perfectly, and the brass tube fit perfectly into the carriers in the stabs. I thought this was a perfect marriage of the stiffness of the carbon and the pliable durability of the brass. The brass tube kept the carbon from bending and the brass tube kept the carbon from getting nicked and precluded the eventuality of it breaking. I've probably exposed myself to the risk of being called an idiot by the ravaging hordes of engineers that patrol RCSE, armed as they are with equations and wielding calculators, and I am probably guilty of that, but I can say that I have lived to tell the tale.

[RCSE] what tape for Ava tips so they don't peel?
Have been flying the Ava some more. What kind of tape do people use on the tips so that the edge of the covering doesn't peel up? I've been having that problem. Or perhaps I should run a bit of thin CA to seal the edges?? BTW, I saw that video of the guy launching his Ava like a DLG. It's really more like a hammer throw, as the idea is to use a loop of line from your hand to the tow hook and just hold the tip in place. Anyway, I tried it and it works fine, but it didn't somehow feel right so I didn't put any power in it. Got maybe 30 or 40 feet anyway. Suspect over 100 is possible if you pull out the stops. No wobbles or anything. Even tho my cg is quite conservative, however, it doesn't pull up much. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Re: Airfoil flight comparison( HN-216)?
Connect the switch to a miniaturized "fence charger" connected to two metal bits, right where you hold the plane to launch. You will probably not launch that way, and you will probably not forget to turn on the tx even when you're launching some other glider. As long as you remembered to be careful and not hold that spot, you could go ahead and load the thing in the car. Have it turn off after a while if another tilt switch cycle doesn't occur. Alternatively, you could just hook the switch to a tiny speaker playing emetic music. I'm not sure, though, that the one form of hurling is conducive to the other. On the other hand, the simple way is probably to use a jack switch like the dlg guys use and hook up something really obnoxious to the end of the red streamer. Like a softball on about two feet of string. Or maybe just something heavy enough to pull out the plug when you pick up the glider.

[RCSE] Re: Post curing West System 105/206
Are you completely set on using West? As I recall (although I don't recall where the numberrs come from) West System doesn't develop properties with post curing as nice as some other epoxies. For instance, I have an epoxy mix picked up from a boatbuilder I know which has a considerably higher glass transition temperature after post cure. ( but again, it's been so long I don't recall exactly what those properties or cure temps are). For a small job like this, I'd probably use Phase Two from an outfit called System Three. You will get a paper telling you exactly how to postcure it. (Two hours at 140F, but it has to be that warm all the way through). An unusual property is that it becomes relatively opaque because of the two phases, which are supposed to make it tougher than a singly phase epoxy. Not sure if this works in terms of strength and toughness, but it handles ok. Heat deflection temp claimed as 64C (147F) For a big job I'd go back to that boatbuilder I know or else look into Raka as mentioned below. If I thought the volume was going to be pretty high I'd definitely look into prepregs. Probably save a lot of labor and get better properties too, although I haven't played with prepregs yet. Your oven might not be enough for them, though. I seem to recall MGS (sp?) epoxies are made for postcure as well. You might try Raka. The proprieter is willing to talk to you on the phone, and can recommend temperatures etc. for various epoxies he has. If you pick the right materials and cure it right, you can use colors other than white, although I certainly wouldn't do it with West. If you must use West, it sounds like 120F for 4 to 8 hours is good. I found it in the following newsletter from West: http://www.westsystem.com/ewmag/18/pdf/tanks.pdf Now, some of that epoxy is mixed slightly different, but not much. Don't exceed 140F: http://westsystem.com/webpages/userinfo/moreinfo/coldtemp.htm (that's a clue that you may not get great thermal properties) Note that, according to the physical properties on the West site, 105/206 is only good for 123F heat deflection temperature. That's why we need to keep it white! I think, given the labor involved, that if the results are important it's a false economy to use the epoxy on hand. Nothing wrong with WEST if you aren't going to use the result in high temps or need really high properties in the resin. In that case I'd use the ordinary version of RAKA because I've used it with good results in the past and it was cheaper. I realize that you probably have 10X the practical experience laying up glass stuff that I have, but I've looked into the post curing thing a little bit. Even if you stick with WEST, if you get it to 100F overnight it will be reasonably well cured overnight. But I understand post curing works best AFTER the initial cure. Bill & Bunny Kuhlman wrote: Granddaughter Alyssa and I are involved in vacuum bagging processes: carbon fiber spar caps, fiberglass over foam flying surfaces, and a molded all glass fuselage pod and boom. We're using West System 105/206 for all of the components. We know that post curing - higher than room temperature heat over several hours to a full day - will make the epoxy matrix stronger, but after a long web search have been unable to get firm numbers for either the temperature required or the recommended time period. If anyone can pass on this information, we'd very much appreciate it. We have our "hot box" made and can take it up to 160 degrees F.

[RCSE] Re: Supra or Onyx JW, these are "Me-Too Designs"
Afraid I must disagree with you about floaters. While I'll grant that the Mirage may have been a benchmark, I'd be willing to fly a good Bubble Dancer vs. you with a Mirage any day. (Not that I'd necessarily win, we all know it's the pilot, and I don't know you so you may fly a lot better than I do.) If it was a bit breezy and we had the same airframe weight I'd even spot you a few points. Actually, I think the Allegro Lite did some of it first, but the Bubble Dancer is a combination of full pedal strength with very light weight, balsa construction, low moment of inertia, and refined aerodynamics. I don't recall seeing that before the Allegro Lite. The Bubble Dancer turns very quickly for a 3 meter. My impression was that it did this quicker than the aileron jobs. I hadn't seen anything quite like it before. Certainly not a 3 meter that you could full pedal launch and also be comfortable doing a couple of circles from a hand launch. Watching Mark launch the Allegro Lite was surreal. Like playing a 33 at 45, or even 78, for those of you who remember vinyl. I don't know what the imitations fly like yet, though I hope to soon.

[RCSE] Re: Thorn Substitute
You could follow the Apogee carving instructions but with maple, use a fishing pole butt for the tailboom, and have a great sloper. If you get a drawknife and a good block plane, it might not even be difficult. A guy in our club has (or used to have) a router jig which made quick work of making straight 8" X 2 meter wings with E205. Some of his gliders had almost solid balsa ahead of the spar. Maynard Hill's electrostatic autopilot trick substituted for dihedral, though I seem to recall he could fly them pretty well without it. Hard to make a high aspect ratio work with lead, unless it has long rigid toys inside. Use tungsten. (now THERE'S an easy material to work with...)
