After reading both Mr. Foamie's, & BgCatFish1's posts, I wonder if the boom popped out isn't the problem with the ones I got. While it says not to fly in more than a 5mph wind the first day I flew it before I gave it to my daughter was the only time it ever flew well. The wind was blowing maybe 8 to 10 mph but I took it to the park anyway, completely forgot to pop the landing gear in it. I tossed it into the wind & it took right off. I was able to fly it around just fine for a few laps around the ball park kind of nosing it in on the first landing. That's when I realized I forgot to put the landing gear on it. I flew it around three more times that day & decided I liked it better with out the landing gear just sort of bellying it in on the grass. I originally bought the things so I would have something I could just take to the park by myself that I didn't care if I crashed or not with between Training sessions at the club on my real Trainer. The other one stashed away for a Xmas present for my son in law who wants to learn to fly. Every time I tried to fly it after that day it would just glide to the ground in about 15 to 20 feet. I eventually just gave it to my daughter so they could go play with them together since I had allready soloed on my Trainer & was off & running. I think I'll have to check the boom & give it a tune up so my Daughter might actually have a chance at flying the pesky little thing.
