"I agree, of course.... I use a bit of kite string which I run up through two pulleys to the ceiling then across the room, where it attaches to a medium sized wrench to act as a stop so the 'copter does not fall all the way to the ground, and…"

"I like your set-up.  I don't have anything so sophisticated but I use a rotating plate for testing yaw...the issue I find is that even though it's got ball-bearings and has relatively low friction the extra mass of the plate and the…"

"Maybe add:  * extendable mast pole so it can freely move up/down by 1m * cross frame from CNC machine to allow the entire mount to move in X and Y freely by 1m in 2D Make these low friction and it will be better able to test your copters."
