YS Engine Help
 

Fellas...A club member has for sale a YS F-120...not a FZ or SF...The crankcase just shows "YS F-120". It's used but reasonable clean and with good compression. It had been partially disassembled so I'll probably send it out for a check-over and parts replacement. The model is obviously discontinued and I can't seem to find any info as to when the model was in production, or where I can get an engine manual. Can any of you gents tell me anything about the F-120 engine? Thanks! Jerry

Give Cenral Hobbies a call, they have all the parts and stuff for the YS engines. ;)

Go to ysperformance.com. They are the place to send it for repair. Check the manufacturer support subforum for YS engines. Dave from YSPerformance is always there to answer questions. He can likely email you the manual.

I have one of these engines on a U-Can-Do-3D and it flys very well. Great engine, easy to operate and adjust. I think it was the first 120 model and sold in the early to mid 90's. I use a 16x6 prop and 20/20 fuel.
