Then you would be well adviced to take a serious look at the Century Falcon SEV2 or its CCPM sibling the Raven 50. For only $400.00 or less you get a true 50 size heli that comes with these expensive features that have to be added later to most others:
1 - 600mm fiberglass - C/F composite blades
2 - a rotor head with a machined metal hub
3 - easily tunable rotor head that has proven itself to be flutter free
4 - a full metal swashplate
5 - an oilite sleeved washout hub,
6 - a full 23 degree pitch range
7 - a carbon fiber torque tube tail rotor drive system
8 - a tail rotor that employs 2 x radial bearings and a thrust bearing in each blade grip
9 - an integral clutch system that does not require any critical alignment
10 - a clutch system design that does not require any shafts to turn inside bearings when in operation.
11 - a start system that disengages the shaft from turning after the engine starts.

Their light weight and low disc loading give it performance like an 80 size 60 ship. Their high quality features insure that they will stay smooth and precise for a long long time just like any Hi-Zoot 60. Yet their crash cost and cost of operation is more like that of a 30.
