I built a little 250 quad for Sophie to learn to fly on, this is her first training flight on it.
To help out, we're buddy-box'd together with me handling the take offs and landings, and managing the throttle with Sophie doing everything else. I think she did great :)
A few years ago I would have said that a 250 quad would have been terrible to learn on, they seemed trickier to fly and you'd crash more. However, the cleanflight will let you setup something that will fly very gently, and of course the toughness of these little 250 frame can't really be beaten.
