The 4#3 is a great little indoor heli - head is a little fragile though - Not good to learn on - being so small and fixed pitch it needs a good zap of throttle to get it up and then basic hovering skills to get it stable - and its just too small to put any sort of trainer's on.
So if you are getting there dispite o few bumps helicadet well done
- I would not have liked to learn on one of these.
