Ok. So I'm flyin my Pico Tiger Moth And BAM! nose first into the dirt. Busts the motor stick off flush at the cowl. So I hog out the busted stick from the fuse and in the process inlarge the hole to about twice the size as it was. No problem, get a new stick and a
can-o-foam,fill in the hole,cram the new stick in and kinda eyeballed it to where it looked right. (pointed slightly down from horizontal). Back to the park we go, give it a toss. Its flyin but man,I really got to work the stick hard to get any air. So I guess my ? is; Is there a standard formula for calculating thust angles? Or
Is it hit or miss? thx DJ
