The new G2S ESC from Hobbywing is out! Let me tell you a little bit about it. How can you improve an industry leading ESC and make it even better? You add unique functions which no other brand currently offer! They are:

FFD – Frameless fan design. Makes the fan both more efficient as well as more durable, which also reduces the strain on the BEC of the speed controller. A finer setting range for the drive- and brake frequency (PWM) settings, to cater for the demands of every racer and racing class. The range is 1K-32K for the PWM, and 0.5-16K for the brakes, which can be set in steps of 0.5KHz.

A-C motor wires switching option. This allows you to swap the A and C motor poles on the ESC by a simple setting in the ESC, which allows for perfect wiring aesthetics regardless of the design of your car.

Drag brake rate. Allows you to fine tune the feel and response of the drag brake. One problem in the past was for instance that, the car would have too much drag brake in slow speeds, and not enough at high speeds. With this new function, you’re able to play around with settings to better suit different track layouts and conditions. Drag brake is crucial for fast lap times in modified racing, and even in some spec classes. Utilizing this new function can give you the edge that you’re looking for! A lower drag brake rate will slow down the speed of which the drag brake is applied. A lower number thus makes the drag brake smoother. I recommend trying a higher drag brake % but with a lower drag brake rate value. You can also try the “Auto” setting which automatically determines the suitable drag brake rate in relation to the RPM of the motor. On the previous ESC (the G2) the drag brake rate was the same as the brake rate control value, so for example, 20 would mean 20 on both these parameters. But now with the G2S, you can adjust these separately. But if you’re looking for the value 20 for example, which you ran on your G2 ESC, both the drag brake rate, and brake rate control values should be set to 20.

Initial throttle force is a new function which is used to get around the cogging effect which can occur when using low FDR values in spec classes. By adjusting this value, you can get a smoother initial throttle feel. It’s motor dependent, and usually with in the range of 0-5%.

Even though I’ve been running the pre-production version for some time, with very good results, this ESC is still new to me as well, so I am also gathering data about its functions right now.

I will be posting basic setups for modified TC on asphalt, carpet, as well as 13.5T EFRA blinky shortly. Stay tuned!
