My dad has a evolution 40 on his trainer. Not really a power house. It runs good for a trainer though.

If I was you I would buy a TT46 pro from Tower Hobbies I think they are about $75.00.

If your new to the hobby you might seek a little help on setting the low end. I have 2 of the TT46. It took me about 10minutes to get the low end set when I was breaking them in.. And I haven't touched them since.

With the TT46 you will be able to move it to just about any .40 size airplane. And not have to buy another motor.

I think if you bought the Evolution you would end up buying another motor for your next plane.
