Performance & Efficiency
Equipped with synchronous rectification and freewheeling technology, the G2 100A offers exceptional efficiency with minimal heat buildup. The linear throttle control ensures precise and predictable response—critical for smooth power delivery on warbirds and EDF-class performance planes.
Compatibility
Fully optimized for the CNHL Super Tucano 1600mm and also compatible with the HobbyKing Avios 1600mm Super Tucano. It supports a wide range of inrunner / outrunner brushless motors, including high-RPM EDF systems and 12-pole 3D setups.
Recommended Applications
- RC airplanes powered by 4S–6S LiPo packs
- EDF jets or 3D fixed-wing aircraft requiring smooth linear control
- Large-scale fixed-wing aircraft needing reliable reverse-thrust landing
Important Notes
Before first use, perform a throttle calibration to ensure accurate response. The reverse-thrust function only works when throttle is below 50 % and should be used for landing only. Improper activation during flight may cause ESC damage.

Frequently Asked Questions about Thrust Reverse, Brake, and Motor Direction
1. Does this ESC support thrust reverse (reverse throttle)?
Yes, this ESC supports a thrust reverse function. Reverse is not on the main throttle channel.
It is controlled through the single yellow signal wire, which must be connected to a spare receiver channel and assigned to a switch on your transmitter.
2. How do I enable the reverse function on this ESC?
To enable reverse, please follow these two steps:
-
Step 1 – Connect the yellow wire: Plug the ESC’s single yellow signal wire into an open receiver channel
(for example CH5 or CH7).
-
Step 2 – Assign a switch on the transmitter: In your radio (e.g. Spektrum NX series, Radiomaster TX16S),
assign that receiver channel to a switch or button. This switch will control brake and reverse.
3. How does the reverse sequence work during landing?
The typical sequence is:
- Throttle at idle (0%) during landing roll.
-
Short press of the assigned switch: activates the propeller brake and stops the prop from rotating.
-
Hold the switch and then advance the throttle from idle: the ESC enters reverse mode and the propeller rotates
in the opposite direction to provide reverse thrust.
This two-step logic (switch + throttle) helps prevent accidental reverse in the air.
4. Why is my reverse function not working?
If reverse is not working, please check the following points:
- The yellow signal wire is plugged into a valid spare receiver channel.
- The receiver channel is mapped to an active switch or button in your transmitter.
- The channel direction (normal / reversed) is set correctly in the radio.
- The throttle is fully at idle when you try to enter reverse mode.
- The motor rotation and ESC settings are correctly calibrated according to the user manual.
5. Can I change motor direction without swapping motor wires?
Yes. The ESC supports motor direction configuration (CW / CCW) through its programming functions.
You can change the rotation direction either via the programming options or, on some setups, by using the dedicated reverse function
on an auxiliary channel. This allows you to correct motor direction without swapping any of the three motor wires.
6. Will the reverse function activate accidentally during flight?
Under normal setup it should not. The reverse function is designed to require:
- Throttle at idle (0%), and
- A deliberate switch command (usually held or toggled) on the assigned channel.
As long as you keep your reverse switch in the safe position while flying, the ESC will not enter reverse mode in the air.
7. Can the reverse function be used as a brake only?
Yes. Many pilots use the auxiliary channel switch as a prop brake control:
-
Short press / quick toggle: activates the brake and stops the propeller.
-
Hold + throttle: enters full reverse when needed for shorter landing roll.
8. Does using reverse shorten the life of the ESC or motor?
When used correctly—only at low speed on the ground during landing rollout—reverse will not significantly shorten the life
of the ESC or motor. Avoid applying full power in reverse or using reverse repeatedly for long periods. Always follow the
manufacturer’s recommendations for propeller size, battery voltage, and current limits.
9. Which transmitter switch is recommended to control reverse?
You can use any two- or three-position switch that is easy to reach during landing. Common choices include:
-
Spektrum NX series: trainer button or a top-hat momentary switch for “press to reverse”.
-
Radiomaster TX16S: SA / SB / SC switches, or a momentary switch if you prefer a “hold to reverse” behavior.
10. Is this reverse function suitable for all types of models?
The reverse and brake functions work best on:
- Scale turboprop-style airplanes (e.g. Tucano, PC-21, T-28, etc.).
- Sport propeller aircraft that benefit from a shorter landing roll.
Reverse is generally not recommended on EDF jets unless the airframe is specifically designed for it.
