You got some good advise there.
However, good r/c car guys are quick heli learners. Collective pitch helis are always tough, but a good simulator and some time on it would make most anyone I know of, with just a little help from an experienced pilot, would do great on a Blade 400. rchelicopterfun

A Blade 400 is no harder to fly than an MSR.A MiniTitan(what I used) or TREX 450 can yeild the same results.
Doubters should see for yourself, its really shocking how much they can be tamed to just get you competently hovering nose out, then in.
BTW, Im not a car guy but have taught car racers planes and helis now. They're quick studies. Doug
