Hey folks,

I have a OS .46 two-stroke, and an ASP .61 four-stroke that I can choose from to put in a Tower Trainer, but my question is which size trainer I should get. I would like to get the 60 size, but I am not sure if either engine is adequate for it (I think the .61 should be.) If not, I'll go with the 40 size model.

Any suggestions?
