Black 20 Amp Brushless Controller

Fully programmable brushless motor controller

1-7/8" x 7/8" x 3/8", 19 grams (5/8 oz.). 20 Amps continuous, for 5 to 10 NiCd or NiMH, 2 to 3 Lithium cells. BEC can run 4 servos on 6 cell battery, 2 servos on 10 cells. Order connector set MJ21011. Atlas motor controllers will work with all types of brushless motors. Atlas controllers come pre-programmed and are ready to use when you receive them. Additional controller adjustments are available; most can be accessed and adjusted with your transmitter, but for easier programming, use the included program card to set all your options. This only takes a few seconds. Settings can easily be changed at the flying field without the need for additional instructions or a computer. Atlas Black Opto Controllers: When you need more than 3 Lithium cells in your flight pack it is necessary to use an "Opto" controller. Opto controllers do not have a BEC (battery eliminator circuit) to power your radio receiver and servos. An alternate power supply is necessary. Use either a standard 4.8V receiver battery pack or a UBEC (KFS001 - KFS003). A UBEC is a device that reduces the high voltage of your flight batteries and supplies regulated power suitable to run your receiver and servos. Every Atlas programmable brushless motor controller has: A 3-Year Warranty, A FREE Programming Card, Over-temperature protection, Works with any brushless motor, Can be used in airplanes or helicopters (has governor mode), An easy to use programming guide, Every Atlas controller can be programmed for NiMH or Lithium Batteries (Type and number of cells), Hard or Soft Start. Motor Timing: Auto Detect, Soft "Inrunners" (0 to 7 degrees), Hard "Outrunners" (22 to 30 degrees), Brake: On/Off. Motor Rotation: Normal, Reverse. Low Voltage Cut Off: Ignore, Reduce Power, Hard Cut Off, Governor Mode (Helicopter use).
