Yeah, Sometimes distractions can turn disasterous. Several years ago I was assembling my Aeroworks Edge at the field for the demo flight to the new owner(buyer). He was asking so many questions that my normal routine was being compromised. Anyway after I took off I handed the transmitter to the buyer and after his second roll the right wing rotated 90 degrees and the plane started to auto rotate downwards I quickly grabbed the transmitter and chopped the throttle and all we could do is watch it slowly rotate towards the turf. BOOM! Turns out during his 100 question interrogation while I was assembling the plane I missed tightening down one side of the the wing on the tube. All I could do at that point was hand the guy his check back! So the moral of this story is just "Shut up and Fly"!!
