I had a Fun Fly that kinda pulled the same thing on me but I wasnt so lucky. It was a G-202 Funfly. I beleve it was super tiger that made it. I had it up 3 times before it died. I had an O.S. .46 SF on it, brand new. I was doing a high speed pas at full throttle. I was going to bring it front and center to pull straight up and do a few rolls, then hammerhead. As soon as I yanked back on the elevator, it snaped in 2 peices and dove straight for the ground. Didnt have enough time to pull the throttle down. I went out to recover what was left and the plane was demolished. I had an aluminum spinner on the O.S. which had cracked into 2 peices and the block was cracked. I was so dissapointed. I had Just got that motor and I had to replace the block already. Good thing I was working at a hobby store at the Time...
