## Description

The RC Electric Parts 40A 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 an XT60 Plug, eliminating the need for you to solder your own plugs on! The ESC can be programmed via the transmitter, as explained in the instructions, or using a programming card that can be purchased separately. Make sure to use an RC Electric Parts Programming card to ensure that it'll properly program the ESC. Benefits: Programmable Super smooth and accurate linear throttle adjustment Supports high RPM motors Utilizes smaller MOSFETs to minimize weight Minimal heat loss Specs: Continuous Output: 40A Bursts Output: 60A for 15 seconds UBEC: 5V/3A Lipo Battery: 2 - 4s (cells) NiCd/NiMH: 5 - 12 cells Voltage Input: 6.4v - 16.8v Size: 71mm x 35mm x 10.5mm Weight: 48g Motor Type: Brushless Motor Max RPM: 240,000 rpm for a 2 pole, 80,000 rpm for a 6 pole, or 40,000 rpm for a 12 pole brushless motor ESC Manual: https://www.rcelectricparts.com/esc-user-guide.html

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.
