Anyone got an idea of just exactly how many degrees you push the stick on the transmitter or how many degrees it makes the surface move when you do a roll or loop? I didn't think so, That's why the TLAR method works so well. Unless you are building a precision aerobatic machine (raise your hand again please) you don't need all that mess. Just get it about right and go fly. Adjust from there as you "feel" is needed including CG.
