The 46 is perfect for it.

I had an Irvine 53 on mine. I was a blast for several months,
untill the day i put softer rubber bands on it than i usually do! The wing lifted off the saddle, and snaped. lawn-darted in from 300 feet. Not much left.

I'm building another, this one will have a GMS 47 (My beloved Irvine 53 is dead.) Also going to make some sort of hook that interlocks the wing to the forward former so the wing can never lift off the saddle again. Also thinking about putting a little piece of fiberglass on top and bottom of the wing joint.

You can controll the speed by using low pitch props. you end up with more pull but less top speed. try the APC 11.5x4 you'l like it.

You can reduce weight in front by 3 Ounces by switching from the Hangar 9 aluminum mount to a Hayes Plastic mount. Its a littel more work, but worth it.
