Engine lettering
 

Has anyone compiled a listing of all the letter codes (esp. OS engines) and what they mean? I am a "newby" and would appreciate help. Thanks, Mike P, North Dakota. :confused:

Engine lettering
 

This just came up on here a coupl weeks ago. Sometimes they mean something and sometimes they don't.

I know who and the final word and that was BAX from the Hobbico service department.

You will have to do a search on it. But there wasn't anything much to talk about as far as the FX - SX series go. Most of the talk was about the rear exhaust 2 cycle engines.

Good luck,

Jim
