HobbyKing X-Car 45A Brushed Car ESC (US Warehouse)
This 45A brushed ESC is a great replacement for your model's stock ESC or for setting up a new brushed power system in your car or truck. It features a low voltage cut-off for use with lipoly batteries. Its compact and lightweight design make it ideal for use in 1/10 scale drift cars utilizing brushed motors.
Features: • Low voltage cutoff for use with Lipoly batteries • Compact and lightweight design • 5.6V/2A BEC
Specs: Continuous Current: 45A Burst Current: 320A (10sec) Suitable Car: 1/10 on and off road Battery: 2 cell Lipo (5-6 cells NI-xx) BEC output: 5.6V/2A switch mode built-in Motor type: brushed Operation: Forward/Brake/Reverse Dimension: 38x28x22mm Weight: 40g
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:
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.
I can't seem to get reverse to work on mine. Forward is great but when I put it into reverse it just blinks the light. Not even attempting to run the motor. Am I missing something? Maybe the reverse is faulty somehow? I'm not even sure what else to try. I even put it in the steering channel so I could control throttle with the TX steering, but that didn't help (same symptoms).
Phillip - does this (instant direction change) also occur when you go directly from Reverse to Forward? If not, and the motor actually stops when you try to go directly from Reverse to Forward, then it is simple matter of reversing part of your system (xmtr throttle channel or motor connections typically). I mention this because this is what I had to do with my installation. I had to reverse my motor connections because the ESC would not auto-cal the neutral point if I tried to reverse the throttle channel on my xmtr.
On my ESC it doesn't seem to mater if I get the one beep or two beeps indicating Practice or climbing mode, the is no delay on reverse or braking action? I would expect the car to stop with the throttle pushed back past neutral with the practice mode on and not reverse until the throttle hits neutral again and is then pushed reverse
Phillip - these connectors are the Japanese Tamiya style bullets found on many 540 sized brushed motors. These bullets are a nominal 3.9mm. Tamiya sells them as p/n 50245 "snap connectors".
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.
awsome esc work well with lipos and with brushed motors.

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.
