Best 13mm thick servo ?
 

I am building an Avonds Strafighter with a turbine. The Futaba S9601 2.4 kg/cm is recommended for the ailerons.

Is there another make/type of servo with the same dimensions but more torque and preferably digital. The servo must be thin but could be larger in size.

The Scotsman says use Ripmax SD 200s 1/4 the price and I have had no problems with them so far BUT am I spoiling the ship for a half-pennyworth of tar?

Fast is good but faster is better.
