So I'm building a new quad copter - from a kit. The kit includes 12amp ESC's. From the specs using a 6inch prop the motor current draw is 11.5amps. Why are they matching those so closely. Why wouldn't they go with a 20 amp ESC. Also I plan to use a Turnigy 1300mah 3S 45-90c battery. From the math I've seen I should get around 6.5 min flight time with 34.6amp continuous using this specified battery. The battery itself can handle up to 58amp continuous draw at 45c. All those electrical guru's out there is my math correct?
Should be enough. The motor current draw of 11.5A is probably a MAX number, is it? Post a LINK to the motors. Why so small? Are you planning on competitive racing?
No competitive racing, just fun of flying. The kit includes motor type of EMAX MT 2204 2300kv If using 6030 props - (11.5amp draw) (thrust - 440G) (Power - 138watts) (Efficiency - 3.2g/w) (Speed - 16300 rpm) and 6030 props are whats supplied with the kit. And yes i would assume max draw at max throttle.
Well get some larger batteries for fun flying, 1500 - 1800mAh. Are the ESCs also Emax? From the spec sheet: I think you will be fine. It seems to be the standard pairing. http://www.ebay.com/itm/4x-Emax-MT2204-2300KV-Brushless-Motor-Simonk-12A-For-QAV250-250mm-QuadCopter-/291494348673?hash=item43de6ac781:g:IUoAAOSwzhVWqIoH http://www.Banggood.com/Emax-MT2204-2300KV-Motor-Gemfan-6030-Propeller-Esc-12A-set-For-QAV250-p-974387.html
