I have a Fat Free Taco (.25 size Fun Fly) with a Saito 40. The plane weighs 3.1 lbs. The Saito 40 is spinning a 12.25x3.75 giving the plane 6.3 lbs thrust, which is a little more than a 2:1 ratio.

The Saito 30 should be able to pull the plane nicely also. If you are looking for a small throw in the trunk and fly type of plane, then look no further.
