buddy boxes have been around quite sime time -just that they did not see wide spread use untill 15+ years ago or so. they are not perfect -no training system is including the one advocated here.pilots need a certain amount of seasoning no matter how well trained.still ticked about AMA not giving you special consideration?
in so far a who taught the Wrights -they benefited greatly byOctave Chanute & his hang gliders as to what worked &what did not. additionally, their gliders first flew as tethered kites, both manned &unmanned(where they found much of the info passed on by earlier experimenters to be wrong) this progressed to gliding their flyer off kill devil hill . they had nearly 1,000 sucessful glides before they tried powered flight. they had to master control first.
