Really hard to stay away from this thread. I've watched each one of the flitetest videos and looked at all the parts list links. Seems pretty straight forward for the H Quad build. If I'm not mistaken the single most expensive item will be the transmitter but looks like a decent unit can be had for a few hundred bucks or less.
It's not an adventure until you cross a bridge
