Hi guys, I am playing around with an old trainer I have, bashing it into a Stick more or less. It is a PT -40 that I converted into a tail dragger, and I have now cut the wing in half and taken all the dihedral out of it. I have a spare OS .61 SF that will fit into the front of the plane. I am doing this because I am advancing beyond my current Trainer's capabilities, I want something a bit more challenging and fun to fly, but I want to keep my old trainer around because I do enjoy the ease of flying it.

Here is my main question, will that .61 just be too much for the airframe? I built this plane a while ago, it is well put together, but not a ton of flight time, I know it is not designed for a .61 but the motor fits into the frame, now I am wondering, should I do it? Will I have too much speed and overstress the airframe ect.

I would like to get your thoughts on putting that much power in a .40 trainer.


Thanks

Manks
