I flew the Panacea with standard corless JR4131 servos on ailerons and elevator and a JR4731 servo on the rudder. The Panacea flew fantastic. Currently I fly the Eclipse with the JR digital servos. The digital servos lock in better, but if you have standard corless servos laying around, I would not be afraid to use them. Now wish my flying skills could catch up to the plane's performance capabilities.
