## 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: My Go to for DIY RC Plane Builds - Just installed in my flying wing that I built myself and look forward to taking it out for a maiden next week. I have used this same ESC in other builds and have a 60 Amp in one of my larger DIY built planes. Great product works very well and if paired properly with the correct motor and prop it should work like a charm. I can say with test It does get warm but I have not had one fail on my yet. Great product!
Review: Cheap in price but not on performance! - Upgraded the motor on my Parkzone Corsair and needed a bigger ESC than what came with it. Didn't want to shell out big bucks for a name brand ESC, so I thought , for the price, I'd give this one a try. I'm glad I did! Performs as well as other ESC's at twice the price. I have well over 30 flights (each lasting 6-7 minutes) and this unit has performed flawlessly. I just ordered another to install in my T-28 after upgrading its motor. Plays a nice little tune when its arming too. I highly recommend this ESC if you are needing a 40 amp esc but don't want to spend a lot of your hard earned bucks!

## 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.

### ⭐⭐⭐⭐ Works but wires are a bit skimpy
*by R***P on December 6, 2024*

I am using it with ducted fan foam jet, and 4 cell lipo. So far it’s flying, doesn’t seem to overheat, but it did take me down to low power at one point. I don’t know if it’s because the lead wires are a bit skimpy. I’d say it’s a good value. If you don’t overload it . the default settings are pretty good and you really need the programming device for 10 bucks. If you wanna program it as it’s almost impossible to do from the transmitter.
