E-flite have now introduced a range of U.S.A made speed controllersto complement their excellent range of brushless motors. The controllers have a unique design that allows you to connect your motor directly to the controller utilising 3.5mm gold bullet connectors(motor connectors and silicone wire included).You wont find a sensor less/ brushless ESC (electronic speed controller) of such a high quality anywhere else at such a great price.These controllers have auto cell sensing and are designed for use with either Li-Po or Ni-Cd, and Ni-Mh battery packs Compact quality speed controllers that wont let you down.80-Amp Pro Switch-Mode BEC Brushless ESC, EC5 Tech Spec Forward: YesBrake: YesTime Delay Brake: YesContinuous Maximum Current: 80AInput Connector Types: EC5, 10AWGOutput Connector Types: 4mm Gold Bullet, 12AWGMomentary Peak Current: 100ALength: 77mm (3.0 in)Width: 41mm (1.6 in)Height: 15.5mm (0.62 in)Weight: 106g (3.75 oz)BEC Voltage: 5.5V Switch-modeOverload Protection: Yes Programmable motor brakingProgrammable voltage cut-offs for 2-3 Cell Li-Po or 6-12 CellNi-Cd/Ni-MH packsDuel BEC regulators for use with up to four servos when using 3-Cell Li-Po and 10-CellNi-Cd/Ni-Mh packsAutomatically sets correct motor timingSafe power-on mode prevents accidental startsIncludes gold bullet connectors and extension wire leads for your motor.
