I've got the freestyle with a Saito 72 up front. Mine too came out nose heavy, but a hatch aft of the wing allowed me to move the batttery back to balance it. The wing is EXTREMELY strong and has never given me a problem. The only problem I had was the bolt that is used as the rudder control horn will loosen up a little in the balsa. Wicking that area with thin CA takes care of it. Mine is about 4 and a 1/2 lbs and is ballistic with the Saito 72. I'm running Futaba 9001 all the way around with a mini on the throttle. The balsa sheeting is thin, so be careful with your sanding.

If you get one, you'll love it.
