I was wondering what the popular opinion would be concerning an engine for a trainer (Avistar). I have been told to get the OS .46AX engine, because I could move it to my next plane once I am ready for it. My thoughts are that once I learn to fly, then solo, and am ready for another plane, I would probably just get a separate engine for that plane anyway?

What do most of you guys do, move engines from plane to plane, or have different engines in each plane? I was considering the OS .46LA for my trainer, and am having a hard time justifying the extra $50 for a trainer. Thoughts?

Thanks in advance

Jim
