I would not use it on a fixed pitch heli but it would probaby work if the extra weight does not affect your model drastically . As stated above and I mean no disrespect in my statements but you probably already have the 2nd easiest type of heli to learn on only to the twin rotor toys so I don't see the point . If you want to really learn then spend the money on a realistic sim and practice . Even when you move up to better heli's the sim will continue to be invaluable as a training aid . Your next move up to the Trex 450 will be a whole 'nuther learning curve as the collective pitch 3D capeable machines perform very different .
