Neo, that explains why it runs fine, I want my tank on the CG. I"m going to use 5245 hitec digital on the elevator, that will save 1 1/2 ounces in the tail, then I plan to put a pull pull on the rudder, the weight of the servo (which will be moved foreword thus having less effect on the tail weight) will depend on how much weight I need if any. Thanks for your imput
