T-HOBBY AM66A 3-6S Fixed Wing ESC For 3D plane

Check out our AM66A ESC, all FPV ESC Collection and the rest of our T-Hobby Products!

Thanks for purchasing our Electronic Speed Controller(ESC).High power system for RC model can be very dangerous.Any improper use may result in injury and damage to human and devices. We strongly recommend that you read this manual carefully before use,and abide by its rules We assume no responsibility for personal injury.Property damage or consequential losses resulting from the product.

1. High-performance 32-bit ARM microprocessor with up to 48MHz operating frequency. 

2. The BLHeli-32 firmware is the third generation BLHeli,following base BLHeli and BLHeli-S 

3. Use the damped light mode. Damped light does regenerative braking,causing very fast motor retardation,andinherently also does active freewheeling. 

4. the code supports features to prevent sync loss.There are tuneable parameters that can make the code run well in most demanding situations,although default settings will work excellently in normaloperating environments 

5.The ESC supports normal PWM throttle mode, OneShot125 throttle mode, OneShot42 throttle mode and MultShot throttle mode. 

6.The ESC supports the DShot150/300/600/1200 digital throttle mode. 

7. The code also supports a beacon functionality,where the ESC will start beeping after a given time of zero throttle.This can be very useful for finding lost crafs. 

8. Integrated continuous 10A/instant 20A high reliability BEC, can load more power servo and other electronic equipment, output voltage can be switched between 5.8V, 7.4V, 8.2V at will.

Turn on the blue light in the red circle of Figure 1, turn off the other two lights, and then click Write Setup write, the output is 5.8V. 

Turn on the red light in the red circle of Figure 2, turn off the other two lights, and then click Write Setup write, the output is 7.4V. 

Turn on the green light in the red circle of Figure 3 , turm off the other two lights, and then click Write Setup write, the output is 8.2V.

T-HOBBY AM66A 3-6S Fixed Wing ESC Buying Guide

1. Choose AM66A for a High-Performance 3D Power System

The AM66A is best suited to pilots building a 48–52 inch 3D or aerobatic fixed-wing aircraft who need a high-performance ESC rather than a basic sport-plane controller.

Choose AM66A when your setup prioritizes:

-Fast throttle response for aggressive 3D maneuvers

-Strong servo power for demanding onboard electronics

-High-current headroom for high-power motor and propeller combinations

-Precise braking and throttle control for aerobatic maneuvers

For a smaller, lightweight aircraft with a low-current motor, a smaller fixed-wing ESC may be a better and more economical choice.

2. Build the Power System Around AM66A

For the intended 48–52" 3D application, the easiest way to select the rest of the power system is to start with the motor and propeller.

Recommended power-system route:

AM480 Motor → AM66A ESC → T13×6.5 Propeller → 6S LiPo

T-HOBBY's AM480 power combo pairs the AM480 motor with AM66A and T13×6.5 propellers specifically for 48–52" 3D and aerobatic aircraft. The AM480 system supports 12×6, 13×6.5, and 14×7 propeller options, allowing the power system to be tuned for different flight characteristics. Choose this route if you want a proven, straightforward 3D power-system combination instead of selecting each component independently.

3.Why choose AM66A?

The key advantage is not simply a higher current rating. AM66A combines high-current motor control, a powerful BEC, fast throttle response, and braking functions in a package designed specifically around demanding 3D fixed-wing applications.

Specification

1.Before using this ESC, please carefully check all power equipment and aircraft instructions to ensure the power matching is reasonable, to avoid ESC damage ultimately due to the overload of ESC caused by the wrong power matching. 

2.lnstall the ESC in aircraft, make sure that all wires and connecting parts are well insulated before flight.Please ensure to connect the components carefully,otherwise,short circuit will destroy the ESc.lf the input and output lines of the ESC need to be welded, please weld with sufficient power welding equipment for safety. lfthe connection is not good, you may not be able to control the aircraft properly, or other unpredictable conditions such as equipment damage. 

3.Do not block the motor during the ESc working, it will destroy the ESC and motor. lf the motor is blocked for special reasons, zero the throttle or unplug the battery immediately. 

4. Do not put the ESC in a high temperature environment or continue to use the heat ESC itself cause too high temperature, high temperature will trigger the electricity temperature protection, will destroy the ESC more seriously. 

5.Be sure to disconnect the battery from the ESc.lf the battery is not disconnected, the ESc may drive the motor to turn by mistake with unpredictable danger.lf the battery connect for a long time,it will be completely discharged and result in error occurred for battery or ESC.
