May 6, 2016 Introducing the RG20 Plus, the upgraded version of the famous RG20. The F330 processor is replaced with the F390 series, doubling the processing speed for even better handling of high kv motors and a slight power increase all around.
Six months in the making, the new RG20 is the ultimate ESC for miniquad racing and freestyle. The RG20 brings the dependability you've come to expect from Rotorgeeks in a smaller, lighter package, featuring damped light and Oneshot capability. The design objectives were to be powerful, robust and small (in that order). After extensive testing and numerous iterations, the RG20 has finally met our standards of performance and reliability. Not as small as other "20 amp" rated ESCs but in a performance league of its own, with a true power rating and the ability to handle much higher peaks. The decision to make the ESC slightly bigger than other 20A designs was based on using larger, high current capable FETs and allowing proper heat dissipation for sustained high output. The RG20 has been tested with 20A continous draw WITHOUT airflow for cooling. And when we were done with the design, we threw another millimeter onto the board to make direct soldering motor leads that much easier. Micro-surgery skills not required! The bare board weighs in at only 4g and measures 20x26mm. The boards are now being made in blue but are identical to the original red boards.

4g bare board or 12g with presoldered with 12cm signal wire and 12cm of 18AWG power leads and motor leads (which you'll end up trimming). With heat shrink it measures 33mn long
Please note, the RG20 is a BEC-less design. You will need another power source for your flight control board and any other 5v equipment. We suggest the micro stepdown regulator available preset to 5v with a JST input and JST output that will plug right into the header pins on your flight control board.
