hi there! are you the gyrodude from RCM??

here's an older thread on the prop hub subject [link]http://www.rcuniverse.com/forum/m_696421/mpage_1/key_machining/anchor/tm.htm#696421[/link]

i do use set screws against the crankshaft but not on the threaded part. i think that would kinda mess up the threads making disassembly hard.
