Power HD HV Coreless Servo

The R20S is the upgrade to proven R20 with more Torque and faster Speed! One of the advantages of coreless motors is their ability to change direction very quickly, due to the low rotational mass of their armatures. The motor spins titanium and aluminum gears that are supported by bronze bushings and dual ball bearings on the output. The main body of the servo is machined from aluminum and houses the motor, potentiometer and digital decoder / ESC board. The SR/SXR/SSR/SUR/SFR multi-mode competition-level servo, overcomes the issues of incompatibility between the multi-branded models. Designed with the convenience of "Automatic Matching" that allows you to plug and use immediately without the need to be tied to the same brand.
