I think it would be a great trainer for you. I have always wanted one, and finally built the huge dynaflight one. I put a 41 CC engine in it and you would not believe how stable it it. It does forward slips just like the real one. It will do aerobatics noone here can believe. I can do pinwheels, flips, almost hover. The 40 size will be a pretty nice plane and a good saito 56 would be right for it. They don't need to be as over powered as mine. I just wanted it that way. You will like it. There are a lot of kits out there. You should like it a lot.
