Well you might find this hard to belive but i just hook all my servos up to the reciver and the rudder is like seized and the Aux Servo dont move at all. the other ones are working but i dont think i wanna take the chance of letting this thing crash im already in the hole 900$. I might as well spend the money and get the good ones. But good call on the servos!. who makes those servos you were talking about like what brand?? will they work with my Spektrum Reciver????
