Getting ready to put together a Great Planes 50cc Giant "Reactor" with a DL-50 for power. Has any one ran the new DL-55? How does it compare to the DL-50? Any significant difference in power or mechanical upgrades from the DL-50? Same ignition and carb? I am going to use the Slimline Pitts muffler but have heard there is about a 300 rpm drop using this muffler over the stock muffler. Shouldn't really hurt this model's performance much. I am also going to try one of the newly advertised PPPro 204 in. oz. Digital servos on the rudder. These servos are advertised right here on RCU for $28.95! The rest of the servos will be Hitec HS-5645's. I just wanted to give one of these new PPPro servos a try. The written reviews look very good for this servo.
