The trainer 60 is built rather heavy. You would be able to fly it with the 46 pro but just barely! If you are flying off a grass field and the grass starts to get long, you may have trouble getting the plane up to flying speed. If you have the plane already then I would find a good 60 engine to go with it. You might want to check out the World models line of engines. For $88.00 U.S. you can get a Tiger Shark 61 engine that would work really well without breaking the bank. I have the 75 size and they are super quality engines.
