Why FOC ESC integrated drone arm combo specifies the KV value of the motor and propeller size?

The propeller is specifically designed to perfectly match the power combo and pull force. The firmware algorithm has mapped the corresponding PWM speed based on the propeller's characteristics during initial matching. Therefore, there is no need to completely replace the propeller; it can be replaced within a small range, such as from 22 inches to 21 inches. does not recommend replacing the propeller due to potential risks associated with mismatched speeds and accelerator curing. Replacing with a larger propeller may risk burning ESC Speed while using a smaller one may result in insufficient tension. Additionally, we utilize resistance and inductance of the motor for sensing position according to specified KV value.

Does the MAD 100A BLHELI-32 have Governor?

The MAD 100A BLHeli-32 does not support Governor (helicopter governor mode). Only the first generation of BLHeli, developed several years ago, had support for the helicopter's GOVERNOR function. BLHeli-32 is now exclusively designed for multirotors.

is this ESC(BLHeli-32 50A 4in 1) bidirectional?

Yes, all our BLHeli_32 ESC is support bidirection, please open the bidirection Dshot, it will work.

how to do the throttle calibration of the Ampx 40A(5-14S)?

First connect motor and adjust throttle100%, then power on and ESC will beep two times. Second adjust throttle 0% and ESC will beep one time. After finishing these two steps, throttle calibration will be set successful. The followings ESC are taken the same way to do the throttle calibration: AMPX 40A(5-14S), AMPX 60A(5-14S), AMPX 80A(5-14S),AMPX 120A(5-14S),AMPX 200A(5-14S),AMPX 200A(12-24S).

How to read the error signal of AMPX 40A, 80A,120A,200A?

You can use a multimeter to measure the signal, if the voltage is 3.3V means the ESC is still good. but the voltage under 3.3V mean the ESC is error.

How to read the RPM signal of ,80A(5-14S),120A(5-14S),200A?

We read the RPM signal by oscilloscope . RPM signal=pulse signal, an electrical speed corresponds to a pulse. for example, the motor is 12 poles, each revolution have 12 pulse signal output.

How to realize RS485 communication?

To relize ESC RS485 bus communication with flight controller, the hardware should be preparated first,The Flight Controller(FC) need to contain a RS485 Transceiver circuit, Connecting ESC via RS485 bus. FC as host, ESC as Device. Each ESC shares the same RS485 bus. FC’s PWM output as Throttle output as usual. Also using the PWM output to configure ESC Address ID before communication when more than two ESCs connecting the same RS485 bus.

Is there any documentation for the RS-485 port in the MAD AMPX 200A ESC?

So far we have not reached a communication agreement with any flight control supplier at present,so this function is not available at present. Welcome flight control developers to provide communication protocol so that we can achieve RS485 communication function in the future.

When I need to do Calibration of ESC?

Yes, All of our AMPX ESC need to do calibration the throttle range when you start to use a new brushless ESC with another transmitter.

How can I program your ESC?

Here is list of our ESC which is not be propramed:AMPX 30A(2-6S), AMPX 40A pro(2-6S) ( it can open and close the DEO),AMPX xrotor pro 60A(2-6S),AMPX 80A(5-14S),AMPX 60A (5-14S),AMPX 120A (5-14S),AMPX 200A (5-14S),AMPX200A(12-24S),AMPX280A(12-24S). Except the AMPX 280A(12-24S) had set the timing degree is 15℃. other ESC is auto-adjusting timing meet almost all application.

Can a drone motor be used as a generator?

Most of our motors can also be used as generators/starters in combustion engine powered system. Please contact us before you buy it.

How much thrust can a drone motor produce?Drone thrust calculation: drone thrust formula

For example ,let's say your quadcopter done weight 2kg in total, and you chose a thrust of the motor, 2/4=0.5kg, so you need fund a motor the 0.5kg thrust at 40%-70% have 0.5kg thrust. We recommend using the Calc tool to select the motors and calculate the flight time.

What size motor do I need to for my drone?(Choosing the Right Motor size for your drone)

If you’re still unsure about which motor to choose, don’t worry! We had did professional benchmark test in our lab, so In each motor data, weight for various types of drones, such as quadcopters, hexacopters,opters, and X8 provides detailed information on the recommended ESC and Propells and the data shows thrust, current output power,input power, throttle position,efficiency, and efficiency. You can choose the motor as well as ESC and propeller as the benchmark guide.

What kind of motor is used for drones?

Generally speaking, brushed motors are used in the smallest drones, whereas larger drone and UAVs will use burshless motors,as they can carry the extra weight of the additional electronics, Brushless drone motors also require an electronic speed controller(ESC) to operate.

What is the difference between V and A motors in the VTOL section?

The design of A motors will be considered fixed, like an airplane, for motor usage, and a higher KV value will be suitable for a higher pitch propeller. The design of V motors will be considered for vertical up and down motor usage, and a lower KV value will be suitable for a lower pitch propeller.

Can we use the V motor for a multirotor?

Yes, of course you can. It is also highly suitable.

What main diffirence between EEE and IPE?

Our brand motor usually have two version: 1. EEE is ENTHUSIASTS EXTREME EDITION for extreme weight reduction while maintaining the highest possible proformance. 2.IPE is INDUSTRY PROFESIONAL EDITION for higher level of waterproof and protection.

Why I haven't get registration email or code?

Please check your Spam email first ,if the email still not in your spam .Please chang another email to try again. Because our service provider judged it as spam and the other party would not accept it.

How do I use the verification code?
