Thanks Dar, I'll check into how old this engine really is.

I ended up not being able to get rid of the play, i tried your suggestions to no avail. With the prop on tight there is still that same play in the crankshaft. You can watch my maiden video and listen to the engine here http://www.rcuniverse.com/forum/m_16...tm.htm#2270151 , .... let me know what you think.
