I do not think you will be happy with a 40 or 50 cc gasser on this plane. Obviously it will fly, but the wing area is still too low for a 14 to 15 pound plane...... If you can get the new BME 55, That should help keep you at 13 pounds or less..... I believe this would be the best setup for this plane, but you will have to wait for the engine.

I have flown several planes that weighed about 12 pounds with the OS 1.60 and they all performed well provided they had sufficient wing area. More than enough verticle power.


LIGHTER IS BETTER
