RE: Predator
Well back to the steering question, not sure how it would work out with out steering. I just used a Hitec 81MG servo to steer mine, works fine. Very simple to set up.
One thing on your maiden, don't horse it off the ground, it will tip stall easily if the speed isn't up. On mine it's a long run out before she goes up. Oh and even though it will loop, I wouldn't recommend it. Those long wings put a lot of strain at the fuselage, can't tell you how many times I've had to reglue the wing to fuselage joint on mine.
