Very nice flying plane. I used a Magnum 91 on it. It's more than the box says, but I did contact the mfg, and they said it would be no problem using the larger engine. The plane actually flies better with it, especially in the wind
It's more expensive the the average trainer, but it's also bigger which means it can handle the wind a little better.
I will see if I can find a before and after shot with the wing, it may be on my other computer.
