Top Flite Sea Fury CG
Today I maidened my Sea Fury at it was a real battle to keep it from nosing over on the take off run. I balanced the plane as instructed but it required way to much elevator on the roll. Even when it was close to take off speed if I let up on the elevator the tail just wanted to flip right over. I may take some nose weight out and see what happens.

RE: Top Flite Sea Fury CG
welcome to the Sea fury. it's a real bear to balance right with the huge weight shift from the gear goin up and down.
I ended up with mine 1/4 behind the center of the CG. It is rock solid with the gear down and a touchy with the gear up. The only way around it I found is not being bashful with the throttle. to get it gun it and stay on top of the rudder. To land it keep the speed up and the nose up.

This is my first warbird, all my other planes are overpowered and require almost no elevator to take off. This is uncharted waters for me.

I balanced with the wheels extended at the mid-point of the the range. I use the factory specified high rate setting for the whole flight. I found low rate to be too soft for my tastes.
As for take off:
I found that if you are too quick on the throttle then it will try to get the prop in the dirt. The way I handle this is to ease in about 1/3 throttle holding full up elevator for about the first 10'-20' feet of the run. As the 'Fury accelerates ease out the elevator until it's running on its mains. Once you are happy with the line finish adding power smoothly. This produces a nice scale takeoff and avoids the nose-overs.
One warning, while I was working on this technique I held the elevator in too long and she popped into the air. Luckily for me full power and neutral controls saved the day. It's better to err on the side of a broken prop then on a premature flight and snap.
