Default Help A Biginner Out - Engines on a 2M pattern plane

Your Used 2M plane is setup for a OS140. I assume you mean the OS140RX, with the normal needle value setup. This limits your choices. What engine mount are your running?

The YS engines are heavier than the OS140RX and putting one in would change your CG. Also you may need a new engine mount and maybe a different tuned pipe.

I would suggest the following:

Have 2 OS140 so get a second one. Many people have a second engine or plane when they fly contests.

Or maybe the Mintor 140 or the Webra 145. These should fit what you have with little CG change and maybe only a change to the nose ring. I believe the Webra 145 is the lower priced option; but not by much.
