Sorry for asking another PBF question guys. I started wading through the 1100 post thread and decided it might be quicker to just ask ....

my father built a PBF, we flew it three times yesterday. take off and trimming were a non-issue, didnt fly it too fast, was fun while it lasted. twice the little bugger bit us by entering a flat spin that could not be recovered from. once was relatively close to the ground only a broken prop. the second time (third flight) was a bit higher and broke the motor mount rails and crinkled right side pretty bad.

so - what is the recovery from this or could this be set up?

weight 2 1/2 lbs, CG 5 1/2 inches from LE, throws; low 1 inch up/down elevon, high 2 inches up/down.

everything seems to work and fly fine except for these darn flatspins

thanks guys

Ahh the dreaded spin of death. The only known recovery is to go full throttle and full down elevator. Although is does not work 100% of the time, it is your best bet.

PBF spin recovery techniques are fully explained on my PBF web page. http://www.yhti.net/~dmcdnld/pizzabox.htm
