see thats the problem I had while a member of DIYdrones. Mabe the terrorist here or overseas may know how to make an autopilot system for rc planes, but if they didn't than now they do... step-by-step.and any kid now can strap a pipe bomb to an rc plane and fly it into their school their mad at and kill people... but mabe im too paranoid. but this could be a whole new way for a columbine repeat... and i just can't be a part of a sight with that much risk just layed out there....so, i took my UAV i'm building and came to this sight and posting the build here now....
