Default scratch built f86

i've finished building my own design f86 with following spec 35" span 260 sq in wing 3/8"thk wt 44oz i think as i weighed it awhile back engine is asp36 with tuned pipe and 9 X 8 apc prop turning 14,5k on the ground i set the pipe to turn 8 X 8 apc prop at 16k on the ground. my question is on hand launch at full throttle the plane torque rolls left violently and needs quick thumbs to correct i have only had someone else hand launch for me, does it make any difference if i launch at say 1/2 throttle i will try and post picture later. plane sue flies fast. i think i may be able to launch vertically so roll won't matter but i would like opinions on this. glides well and lands easy

Default RE: scratch built f86

Hold the plane with a right bank and release it that way. A good hard, NOSE LEVEL throw takes away some of the early launch squirrellyness. A pull to the left on launch is a good indication that you're flying a pretty hot plane[8D]!
