High-performance 32-bit processor with a running frequency of 72mhz combined with advanced algorithm optimizes the speed governing. Together with the adjustable governor parameters guarantees every pilot a precise control experience high voltage built-in bec the built-in switch mode bec with an adjustable voltage (6v/7. 4v for the platinum 25a v4, 5v~8v with the step of 0. 1v for the platinum 40a v4), a continuous current of over 3a/7a (3a for the platinum 25a v4, 7a for the platinum 40a v4) and a peak current of 7a/18a (7a for the platinum 25a v4, 18a for the platinum 40a v4) can supply enough power for your servos to operate efficiently. Deo technology the deo (driving efficiency optimization, or so called ""active freewheeling"") technology implemented in the esc has multiple advantages. ? Quicker response to the throttle change. ? Higher driving efficiency, longer flight time. ? Lower esc temperature and a more reliable operation. Reverse brake with the reverse brake mode enabled when landing can effectively shorten the sliding distance of the fixed-wing aircraft to simulate the landing of a real aircraft (within a super short distance). The normal brake mode, proportional brake mode, and brake disabled mode are also available; the brake amount is adjustable in normal brake mode while in proportional brake mode, the brake force will be automatically allotted on the basis of the position of radio throttle stick. Multiple protections multiple protection features include, esc thermal, capacitor thermal (hobbywing-patented technology), esc overload, throttle signal loss (or fail safe), and low voltage cutoff effectively prolongs the service life of the esc. Other features a separate programming port for connecting the programmer on this esc allows user to ? Program esc, ? Check flight data include minimum voltage, maximum temperature, standardized rpm and speed curve (in heli governing store mode) of the flight data recorded by the esc, ? Upgrade esc firmware with a multifunction lcd program box or a wi-fi module & our apple/android phone app. Product specification type brushed/brushless : bl high voltage/regular : regular specifications cont. /peak current : 25a/40a input : 3-6s lipo bec output : switch mode:6v/7. 4v,3a wires & connectors input wires : red-16awg-100mm*1/black-16awg-100mm*1 output wires : black-18awg-100mm*3 input connectors : no output connecotors : 3. 5mmgold connectors (female) esc programing via transmitter : not supported led program card : not supported led program box : not supported lcd program box : supported wifi module : supported program port : separate program port firmware firmware upgrade : supported size & weight size : 47x22x10mm weight : 27g (hw30215001)
