Sorry about calling it an OS engine. The guy told me what the engine was & I forgot. So I called it an OS engine because that was the name brand that came to mind. 
. I like the wing span on the Tower Hobbies Trainer better than Avistar, but I want a plane that I can do more than fly in circles once I learn to fly it.

.Paula,I have 2 of the TH trainers RTF and 1 Avistar.
All three came with the 40 OS engine.
Everyone else I know that has a TH trainer has a OS 40 engine on it.
It's stamped on right side of the engine looking at the front and a owners book from OS comes with it
Don't worry.
That trainer you just ordered will do more then circles.
You can loop,roll,and although you can't do an outside loop you'll have fun watching it do a hammer head stall trying
BTW,
Lot of others say it can't be done but you can loop and do 360 turns at the same time.
Takes time to do it but it can be done
