I have a Saito 82 in mine along with spring air retracts. The 82 is plenty of power and it is probably the easiest tail dragger to get off the ground that I've flown. It will float on landing and really bounce if you try to drop the tail too soon. Land it on the wheels [don't try to three point it] and let the tail drop on it's own. If you use the stock tank and fill it full you could probably fly for over 20 minutes. Great flying plane and the colors look super in the air.
