I tend to agree with ****cano; my sig one is hinged at the center of stab, and 45 degree throw is plenty of elevator. definately keep it as light as possible. it will harrier better that way. as weight increases, so will wing rocking. mine is pretty good, will rock slowly when harriering below 45 degree nose up. one thing to watch for, though; if you go a little over 90 degrees while stationary or backing down, it will torque roll so keep that in mind! mine is saito 72, 4.75 lbs. does well. hope this helps!
