It's a flight test 35Amp ESC, with 5V/3Amp BEC. Motor is Suppo A2208/17T 1100kv. I love Flight Test and have both B and C power packs, but I love this Suppo motor. It is so quite in flight with the Simple Cub, that you can't hear it at times, and flys for 18 minutes, on a 1300mA, 35C Lipo. I fly around a park by my house, just easy flying. I have Flaperons, and added another servo so I can drop a parachute on the bottom of the fuselage.
Another question...on the AR620, what is the BATT (pin 1) used for? Can you plug in the LEDs there?
Also, when you use a servo, isn't it just a pulse, not a constant current draw?
