ESC Programming Options

Having cooked my HobbyKing ESC attempting to resolder and neaten the wiring, I picked up my old Turnigy Trackstar Turbo 120A ESC and 7.5T motor and put it back into use. Soldered it all in nicely and then grabbed the Programming Box...

There are so many options that I did want to get to know when I was using it previously so it was off to Google. After some research (on the not to obvious options), I've managed to collect some information.

1. Operation mode -
Pretty straight forward here; most will go for the "forward/reverse with brake" option because that makes sense.

2. Initial brake -
The first tap of the trigger and how much braking is applied. This can go from very little to maximum effort at the first tap. Choose wisely, I leave it at a gradual increase as you would in a real car.

3. Drag brake -
Braking effort in neutral trigger position. Some apply a little drag brake force when the if very little drag with the motor of choice and driveline of the chassis. Very little drag will allow the chassis to continue rolling once you've released the trigger. Drag brake can supply "engine brake" feel to the motor.

4. Brake strength -
Maximum braking effort. Set to 100% will give you maximum brake but you can decrease this if you choose to.

5. Punch Profile -
Initial throttle effort. The amount of throttle applied when the throttle is first triggered, this can be very little or set to maximum. Low setting with give gradual speed whereas maximum can give wheelspin on the spot.

6. Neutral dead band -
Activity on the trigger within set limits. You can set this to have a very responsive trigger at initial touch or have a little delay before anything happens.

7. Boost timing -
Triggered when a certain motor RPM has been reached. Until that point there will be no boost. Shouldn't be set too low at this can cause boost mid-drift which can cause spinout.

8. Turbo slope -
The rate at which turbo timing is added once the preset RPM has been met. This is programmable in steps/0.1 sec. A smaller number is a gradual increase with larger numbers giving extreme increase in some conditions

9. Turbo timing -
Used to set when the turbo kicks in. Once the motor reaches a certain RPM, turbo activates.

10. Boost timing RPM -
Works throughout the entire throttle range; even at low throttle, boost can be activated depending on setting. The setting will be divided across the throttle range. For example; set to 5°/1000RPM, boost will be 0° up to1000RPM, 1° at 2000RPM, 2° at 3000RPM etc. These numbersare for example only and will differ with ESCs with start and end RPM etc.

10. Turbo delay -
Time delay for the turbo to kick in once full throttle has been enganged. Most ESCs will also wait until the boost has done it's job before applying turbo.

11. Boost timing ACC (Acceleration)
This is the RPM increase or addition of the boost timing. Lower values will increase torque but will increase motor temperature. Best to use values above 350RPM/ACC

12. Reverse speed -
Revesing speed. Usualy best set to a low value as the rear wheels of a RWD drift chassis will find it difficult to pull the chassis.

13. Drive frequency -
This adjust throttle feel at partial throttle. Higher frequencies give a better feel at the cost of temperature increase of the ESC. Lower frequencies give stronger acceleration.

14. Brake frequency -
Similar to drive frequency, lower frequencies give progressive braking, higher frequencies give more initial brake.

15. Temperature set -
Sets the cut-off point as a over-heat protect. This will stop the motor overheating. Useful if you're playing with values that may increase temperature.

16. Restore default -
Factory restore the ESC to default setting.

I state again that these settings are for this Trackstar ESC and there are some ESCs that will have more available options. As I found the info online, there will also be info on the other available options.

Thanks for reading and I hope this has helped. Keep drifting fun!
