Put an IPS-DXa in it. Then set up all neccasary radio equipment and it would be great!

Im thinking to mount the motor on top of the wing...a removable motor mount...so in the future i could change the wings between this two models....


Do you think a GWS 280 DD would work?

By the way..thanks for your comments Alex and Ryan

I would put the motor up front, not on the wing. One reason you should have it on the nose is, the motor would have to be vary, very high off the wing, 10"-11" in order to get clearance. Also, the GWS IPS "A" gearing is going to be the motor you will want for this. The 280 is just a little too big. Also this being a trainer, you won't want it to be too overpowered. I would use Hitec HS-55 servos or GWS Naro series, good luck with the project, keep us updated!
