Make sure you have a little TOE-IN on your wheels so it is not so wild on take off.

I had a H-9 Cub with a Saito 50. It was a good match. A OS 46 seemed like too much engine and the two stroke didn't like extended low throttle operation like the four stroke did.

A LA 40 is not bad in a full wing one. You have to keep the throttle pretty much open which is good with a two stroke. amazing with a 80" wing?

Enjoy,
