Hi guys

I am whipping together a Great PLanes Big Stik 40. I have three HS-325 standard servo's and two HS-635 high torque servo's at my disposal.

I know high torque servo's are OVERKILL on a plane like this but I might as well use them as opposed to buying new ones.

My question: Which control surface needs the most torque? I can either use the 635's on the ailerons and the 325's on the rudder elevator and throttle, or I can use the 325's on the ailerons and the 635's on elevator and rudder.

Not quite sure what the optimal choice would be here.

Marcel
