The 46ax of course will fly it fine with plenty of power. I Love mine with the 4 stroke 61 asp/magnum. I have a friend who flew his with a base 40 LA OS. Unlimited vertical? WHY? The 46ax will get it off the ground in about 15 ft. If I were you I would try and trade your 46ax for a 4 stroke 61. The 2 stroke will give you more speed, but the four stroke will give you Torque!!! Swing a large prop fly slow and take off in a short distance. It will look like an Eindecker in the air flying around.

I only fly this plane once in a while now but it's a nice relaxing plane to fly.
