My fastest MOC was a Formula with 2x BuWizz and 2x Buggy motor with top speed about 25 km/h (15.5 mph) and I wasn’t even trying to make it that fast. Gamemasterks – July 3, 2020 Every Technic RC MOC builder should get this! It provides way more voltage than another of the ...
PURPOSE:To set optimum feedback gains at both the times of accelerating and decelerating by performing PI calculation acceleration or deceleration when an actual rotating speed falls within a first predetermined range, and introducing an acceleration and a deceleration to its formula. CONSTITUTION:When ...
