today i bought a 13 inch span peanut scale rubber model. im going to try to put the aa guts in it. i built the frame and it weighs almost nothing. im gonna cover it with saran wrap to make it really light. it has aprox. 17in of wing area so if i get it to weigh around 20g, it should fly o btw, its a mono-wing.

I came up with a mod last night while soldering. Fumes or AA's on the brain? Anyway, I want a flight that is not as extreme as a vanilla Mono, is able to do tricks like a bipe, which leaves out a mono with canards. So what I came up with was to remove half of the lower wing. I just flew out the battery of the one I set up this way. It handles between the mono and the bipe. I didn't need to put the elevators down. It climbs and turns faster than the bipe, but has the same glide as a bipe. I think this has potential. As is it is, in my opinion, better that either the bipe or the basic mono. I have yet to put canards on an 06. I am thinking about trimming a set of lower wings until I find the best combo. But the first try is good. Good enough to post and fun to fly.
Here is what I did: 1. measured the lower wing length on the front and rear. I came up with approximately 82 mm.(these numbers were found using a bipe).
2. I marked the front and rear of the wing and sliced it in two. I used a razor blade, please be careful when attempting this mod.
3. I stuck the wings in a mono. And flew.
I am still using the silk ribbon mod, but that is the only other mod on this plane.

I didn't think it was possible that I was the first. I don't remember reading about it though. Now I thinking about putting a set of lower wings on it. I want to see if that helps the sail plane issues.
Also, if you want I'll post pics of a failed mod from last weekend. Let me know. Tim

neurotex, a basswood prop will be pretty durable. the best part about making your own is you can do one that matches what you need perfectly. this is where having a thrust stand and a meter to check the amp draw comes in handy.
If only I knew what would work perfectly. Finding the perfect props could become time consuming but I think important since the prop is arguably one of the most crucial parts of a plane. I've started a prop thread, and before it sinks into oblivion, I hope you could post some info about making a thrust stand there. Any other info too would be a great help. At the moment I'm building a prop balancer and making templets.
WASPS-Flyer, post some pics of that peanut flyer if you can.

hey, i was just wondering. is there a difference between the 05 aa bipe. and the 06 aa bipe?
I may end up buying the 06 for chopping purposes- be nice if it was better and they got some of the bugs out.
After building my prop balancer I discovered my home made prop is out of balance. No surprise there- gotta sand some more.
What was surprising to find is that the stock AA prop is out of balance also. Or at least the one I tested is. Took a lot of scrap'in plastic to get it right. Don't really believe an unbalanced AA prop would cause much harm or effect the flight since the weight is so minimal.

the early 05 bipes could not glide. Spinmaster had them geared for 3+. You had to fly at max throttle all the time and you needed wind(think the f-16) and a flght of more than 8 minutes was exemplary. There was no glide factor, when let off the gas it dropped like a rock. I would say that the glide factor was 10/1. It should be obvious that I had one. A bunch of people bought them and started "fixing them" thats how the mods started. The first mod I saw was a professor type demo'ing his plane. He had what appears to be cassette tape tied to the tail, the ribbon mod(I still think silk is best). The next couple of mods were mono mods. Check online for AA forums, I don't remember which I was reading. To give you an easy understanding, the late 05's and the 06's have a glide ratio closer to 1/10. My thought is that the changed the formulation of the styro. Tim
