i want to do the same, i can tell you you need 50 motor mount.....let me know if you find any thing else....thanks

Found this

There are stages you can do if you want;

The very first stange to putting in a 50 engine is the engine mount and fan/hub because the 30 fan will not fit on the 50 engine (although I suppose for sake of argument it could be bored out to fit over the bottom of the 50 engine shaft).

So broken down it is;

1. Engine only (fan/hub and mount). With just the engine alone changed the heli will fly but will be running at a lower headspeed than you really need and the engine will not be utilising it's power and torque. If you fly it this way be very mindful of over-speeding the engine and adjust the throttle curves to make sure you keep engine revs where they should be
(the OS 50 runs at about 2000 rpm less than the 32 or 37 to develop max power). You'll prob also need a wider pitch range on the blades to keep the engine loaded properly.

2. Change to the 50 gearing 10/85. At this point you'll have decent headspeed and less tendency for over-revving the engine.


3. Add a longer boom, belt and main blades (the tail blades and boom supports can stay the same). At this point you'll have more lift and stability from the bigger blades and can fully take advantage of the power of the 50 engine.


I have a Raptor that started life as a 50 but I have an OS46 in it at present and kept the 50 gearing but have fitted 550mm blades and this suits the 46 very well. It has more power than the 37 but not near as much as the 50 hyper (but burns much less fuel than the 50).
