I have one laying around here and i have 3 .40 size motors. that need to be test flown before they go on their permenent homes. Will this plane work. They are 2 ST GS 40's and a OS la 40. I know the LA will work. also how hard would it be so i could run a four stroke on it.

I used a ST 40 on my Superstar trainer no prob. I also have used the trainer as a test bed. I wanted to see how much power a Saito 40 four stroke could develop. It did fly but not very well. Not enough engine for a 40 size trainer. Throttle was a bit of a hassle to set up but was doable.
