Does a new brushed ESC work very differently from the Brushless ESC's? I recall my older/original brushed controllers would power up and if not "centered" power would instantly go the wheels. The brushless flight ESC's need to throttled down to initialize. Just got this 45A brushed ESC to replace the one in my 1/10th Associated. Plugged in and powered on, turned on radio (BEC) switch but cannot get any power output to motor. Tried attaching a meter to the output and definitely get no voltage. I tried with throttle at "idle", throttle at mid-way and full - no initialize. Should I troubleshoot using the steering channel? Is the ESC toast [DOA]? I was using a 2S pack, so I know I didn't over-voltage it.

Nevermind . Battery read 100%, but is bad. As soon as the ESC tries to pass a load the voltage drops and the ESC/Rx stop. Used the new battery I also ordered and it works great. Doesn't seem "faster" on the top end but absolutely can pump more amps from a cold start - need to adjust the differential for slippage now.

What is the turn limit for this ESC. Want to use it with a 540 15T Dynamite motor.

Not sure on the turn limit, but I run a 17t brushed motor with tall gearing and it the esc never heats up. I run it really hard. 45 Amp is quite a bit for a brushed ESC, you might have problems with sub 10 turn motors.

Hi there! I just made a foam wire-cutter using this kind of ESC.. Maybe usefull to you, so I thought I'd post a video of it :)

Hello, I am having trouble turning off voltage cutoff. I am using in a Legends car with one cell lipo and a Turnagy voltage booster. Car will run briefly on a fully charged battery then dies. VOM shows 6 V to receiver from booster and only 4.2 volts from 1 cell lipo.Older speedo's without voltage protection work fine in car. Any suggestions? Thanks in advance for your reply! AW

Turn off the inline power switch and then hold the set button while turning the power switch back on. One beep means it is off and two beeps means lipo protection is on.

This will work with a 12V car/motorbike battery. I removed the power wire pin from the center of the servo connector and used an external BEC. I did not try the built in BEC as is. This is a Car battery driving a 24V motor on a rascal for a project. The motor seems to hang for a second when switching quickly from one direction to another. I can reverse the hang direction by switching the leads on the motor wire. The flashing indicator light goes solid at this time. This may be because of the braking function. If I wait for a half a second to change direction it works fine. I'll try with a 7v battery and a speed 400 motor to test it at some time. Changing to crawling mode - the motor runs for a few seconds and locks up, never to return unless the unit is rebooted. again, maybe the braking function built in? It would be nice to omit the braking all together for a project like this. Here is a video:

The 24V DC motor is drawing 3A from the car battery.

It only hangs when quickly reversing in ONE direction. after that i can quickly stop and continue in the same direction, or go the other direction. it just hangs from CW to CCW if I switch the direction quickly, solid red light.

Fixed by following FourDollarRacing's programming tips. Set to crawler mode. Works perfectly now. Thank you. Great product for quick and cheap "Giant servo". If you don't need centering.

This brushed ESC is an excellent "sport" speed control. It is easily programmable, but has very limited functions. The case-size is relatively small, and will fit most 1/16th and 1/18th cars. I have successfully tested this speed control with sealed-can motors, and SPEC motors as low as 19 turns. So, it should power two crawler motors, wired in parallel with NO FEWER than 40 turns ….

The Low-Voltage Cutoff works very well; however, it must be carefully programmed to avoid changing the drag-brake mode. Release the programming button, immediately after the first “beep” or “beep-beep”, to program the LVC. If you wait until after the arming song, this changes the drag-brake mode instead.

The “practice” programs no drag brake, reverse delay, and reverse, for buggies and touring cars. The “climbing” mode programs forward-drag brake AND reverse-drag brake, with NO reverse delay in either direction, for rock crawlers.

The standard bullet motor connectors and Tamiya battery connectors are compatible with most electronics, and I haven’t even bothered to install low-loss connectors. I still have this item on my wish list, because it is a great value, and works as intended. The only thing missing is reverse lock-out, for racing….

Nice little brushed, reverseable ESC. Worked great resurrecting my RC10T with an old 27 Turn stock motor. Easy to setup via the instructions found on this site and would buy it again vs. the name brand ones.

Just installed this in my old/very old Tamiya Boomerang. Running a 7.2 NiMh and can I say WOW! This was an upgrade from the original MSC, which couldn't handle the 20T motor. This buggy now runs faster than it ever has and programming the ESC was a snap. Also I am running this on my ancient Futaba Magnum JR 72Mhz radio and receiver, the BEC works flawlessly though I did need an adapter plug to fit the receiver $3 no big deal. A great ESC for the Brushed crowd! It completely resurrected this buggy that I love so much. Thank you HK

I bought this for a Traxxas Rally 1/16.Running a Titan 12T 2s lipo in it and so far so good.Not to much heat and plenty of power to run the rally.Hard to beat anesc for less than $10 with LVD.
