After plugging in the ESC to the motor if it is running backwards just change two of the wires to reverse. When buying motors, batteries and ESC`s make sure the connectors are compatible.

As well as the ESC's are cable of the voltage that you will be using 👍

The battery voltage is one factor that determines how fast the motor spins. The other is Kv, that is revolutions per volt.

The faster a motor spins a prop, the more amps it will draw. To avoid overloading the motor, high kv motors will use smaller diameter props than the lower kv version.

The motor size, 2212 for example, refers to the size of the motor stator, 22 mm diameter & 12 mm long


How many amps the ESC can provide. If the motor + servos draw more amps than the ESC is rated for, you will burn it out.

Don't cut it too close, it's good to have a little overhead. If the motor can draw 30 amps, use a 40 amp ESC.

Each 9g servo draws about 3/4 of an amp at full load. With a BEC rated at 3 amps you can safely use 4 9g servos. You can use more servos provided you don't use more than 4 of them at one time or don't put all under full

If amp = watt/volts, and I know my battery is 7.4v ect. how do I find out the watt the configuration is using to get the amp draw?
Thanks

watts = amps x volts

A 300 watts factor sports airplane 2 ibs. and under is 5,630 mah about. 300 watts divide by battery voltage ( 11.1 V) = k k x (10/60) is the flight time divide by 0.80 = kn. Kn = kn x 1000 = 5,630 mah. Watt factor being determined by the weight of the airplane. C is the discharge rating for the ESC engines at 30 A. But on the video I saw he used a 1000 mah. How is this reduction so? About 1/5 less than the 5,630 mah. Thank you for answering it.

30 A x 10 minute = 300 watts (10 minutes being the potential difference in battery capacity or voltage + to - charges) Voltage. Conventional flow of electrons.

One more thing, when u you guys end your day flying, do you disconnect the battery from the ESC or just shut off the radio?

yeah, I’ll fly it at the park when it’s finished. Hawai’i.

where are you getting your info, chatgtp?

It's always better to unplug the battery first, because if you just turn off the radio it can trigger failsafes in the ESC or preprogrammed ones in your radio and it can pop to full throttle! (I had that happen the other day, when my receiver must have gotten unplugged when I was trying to fit my battery in the plane😬)
