Bipe Flyer

I got my Fathers Day present a little early. It's a FlyTech Dragonfly.

I always wanted an ornithopter.

Happy Fathers Day, Bipe. I know its early, but hey! Your a father and deserve some appreciation.

Would you do a small favor...Jump over to my Cherokee thread and check that out..... Thanks

Would it be considered bad form to do a glow conversion the same day that you get the gift? What about if you never flew it stock, just started knifing into it right away? [X(]!

If I could find a glow engine small enough, you know I'd give it a try. The little sucker weighs .8oz RTF.

That's just incredible, [.8 ozs.]........it would have to get scaled way up to be practical, and there would have to be just the right gear reduction.

Here's a video clip. There was a slight breeze, which really affected the way it flew.

I think I saw a previous video of this insect(?)

It seemed very pitch sensititive that it was porposing from stall, dipping to forward flight and pitching up to a stall again.

Have you had better luck with yours?

Sorry can't open your video now.

Bipe Flyer

OK, try the video now.

It does tend to get into a porpoising oscillation, which gets worse and causes it to come down. I've found that constantly turning prevents the porpoising. I'm going to try a couple of tail mods to try to improve stability.

Bipe Flyer

Well, that was easy. I just did a quick and dirty test. This little mod has greatly reduced the porpoising and improved the spiral stability. It can now fly around easily at low throttle and climb at full throttle. I can pretty much keep it in the air as long as I want now, whereas before I was limited to 5 to 10 seconds at a time. So now I'm going to replace the entire tail boom (it's a piece of depron) with one that incorporates more horizontal area and make a v-stab.

Bipe Flyer

The mods are done and it flies much better. It porpoises very little now, but if it does start porpoising, I just turn a little and it flattens out. The little vertical fins are just enough to prevent it from wanting to go into a spin in a sharp turn.
