Boy it.ll go like a jet fighter with that size motor I run a 50 on mine and it scoots along lets know how it goes oh I also put the servos for rudder and elevator in the fuse at rear but it needs about 3 oz s of lead doing that best of luck Don,t fly it in to much of a breeze mine tipped over on its back at about 10 feet up mind you it was blowing a fair ole gale snapped fuse in half so build a new fuse for it thats the trouble with that big a wing area (84inch)
