ORIGINAL: flycatch
Simple solution to your problem. Throw it in the trash bin and stop playing with a toy. Get yourself a 600 size model helicopter either nitro or electric and a mentor.
So your solution is for him to learn to fly on a 600 dollar or much much more expensive machine, when he doesn't even know how to check the $90 coaxial heli for out of whack parts, after saying he has been flying for a few days. That has got to be one of the smartest answers I've ever read.
