## Description

The 30A Electric Speed Controller (ESC) is a great little powerful ESC that runs very well and doesn't run hot like other ESCs. The ESC comes pre-soldered with 3.5mm Bullet Plugs and the XT60 Plug, so you do not have to solder your own plugs. Features: Programmable Super smooth and accurate linear throttle adjustment. Supports high RPM motors. Utilizes smaller MOSFETs to minimize weight. Doesn't get hot while running. Specs: Output: Continuous: 30A Bursts 40A for 10 seconds BEC: 5.5V/3A Input: Lipo Battery: 2 - 4s (cells) NiCd/NiMh: 5 - 12 cells Size: 45mm x 29mm x 15mm Weight: 37g Motor Type: Brushless Motor

Review: Excelente
Review: It immediately exploded the moment I plugged it into my Li-Po battery. I checked it with a multimeter and sure enough, the item is defective. The package it comes with is stapled as well.

## Questions & Answers

**Q: What is a good battery that works with this? Preferably under $25**
A: I used 3s 2200 mA

**Q: How do i calibrate this esc when i first turn it on?**
A: We highly recommend doing a "Throttle Range Calibration" Procedure. In brief, the procedure lets the ESC know exactly where the max and min throttle positions are, so there is not a dead spot at the top or bottom end of the throttle. Our online user guide (see the product descriptions for the link) has detailed instructions and a video on how to do the procedure. In summary, all you need to do is power on the ESC in the full throttle position, wait a few seconds until you hear a few short beeps, put the throttle in the minimum throttle position, wait for another beep, and power of everything.

**Q: Is it able to do forward and reverse ?**
A: This ESC cannot be reversed as would be used to back up an RC car.  But by switching two of the three motor wires manually, you can reverse the direction of the motor.  This is useful only in RC airplanes where you might use a pusher propeller configuration or for counter rotating propellers.

**Q: Will this esc work in rc trucks?**
A: Its not ideal for RCs as it has no reverse, no proportional braking (only 0 or 100%), and will cause cogging with some motors.

### ⭐⭐⭐⭐⭐ Review
*by R***. on 12 July 2023*

I very seldom write reviews but just had to for this esc. I bought it to replace the one in an electric rec helicopter that is probably 15 or more years old. All the connections matched perfectly and I had the servos all working but the motor would not spin up. You can scan the QR code on the esc and it brings up the online manual which is very detailed and easy to follow if you know what you were doing which I didn’t. I called the customer service number and actually had a person answer wasn’t press this number press that number for this or that. An actual person answer that spoke English and he was able to walk me through some troubleshooting and basic set up procedure and got everything working perfectly. He was going to send me a replacement if we couldn’t get this one working but it turned out not to be necessary. I would highly recommend this company.
