My Posts This: Topic Forum | Hi,
I think that you need to change the gear ratio first. That means you must change the main gear and the pinion gear. After this you have to change the tail boom and main blades including muffler for 50. If you haven't all this stuff for the 50 conversion, i don't recommend to make any change.
