Dave,

You really don't need to spend all that money :-) I upgraded my 30 to
a 50 doing only the following:

1) OS 50 - Note: You must CUT about 1/8" off the end of the crank
2) Upgraded the gears to an 85 tooth main gear and a 10 tooth pinion

No longer boom, blades or belt. That's it! Flies fine!
