RE: Ground loops
Flypaper - I was in the service from '92 - 2003. That was the first R/C kit I built after joining. I built mine in 2001 so I had forgotten a lot. Mine came out way nose-heavy. If I'd thought about it at the time, I could have saved a lot of weight by putting the servos in the rear instead of dead weight. It is fun to fly, but mine is over-weight and is pretty fast with an O.S. .15 CV-A in it. I have to keep a spotter handy because I tend to let it get away and lose orientation easily. I'd build another one though and use lessons learned to keep it light and make it better overall. I just wish the cowl was better.
