Hey that's pretty cool, BugDevHeli! Is it your own design or based on a kit?
Trouble is in production when the assy guys are spitting out one a day, to earn everyones keep, things get missed - parts shortages, engineering changes etc. I have a great deal of respect for the guys who can consistently throw a new design together, but noone is perfect and everyone has to learn. The five hour test (say) keeps those mistakes inhouse, where they belong...
Any of the bigger players do production tie-down testing? Are any of the sub-assys tested, eg rotors in whirl-tower, or is quality inspection to drawing relied upon?
