Would this work well with the motor from a Novak Hv Maxx ? The original one part #55-3020-1 from 2004 ?The speed controll kicked the bucket but the motor is still good just need a cheap replacement thank.

I am unable to get this working correctly in my slash 4x4 with my venison motor. It works for a couple seconds then it cuts power and then shuts down entirely. I flashed the latest hoobywing firmware (didn't work at all with firmware that it was shipped with). I also tried with a spare speed passion motor which worked worse. I have tried many timing options and nothing seems to make a difference. Not sure if my setup is bad or the ESC has problems but I am unable to get it working correctly

I found these instructions that fixed my problem' When your ESC is off... FIRSTLY: Hold the "SET" Key while Turning on the ESC Switch from "off" to "on" SECONDLY: Turn on your controller and set the THROTTLE TRIM To 100% or full THIRDLY: Press the "set" key ONCE and a single beep will occur while leaving controller at NEUTRAL FOURTHLY: Pull the Trigger fully to the position of FORWARD THEN Press "set" key while holding it and 2 beeps occur. once 2 beeps are done go back to NEUTRAL POSITION LASTLY: Push the Trigger away To BACKWARD and make sure to push the trigger is pushed whilst pressing the set key... Once its all done beeping.. RESTART ESC...

Hello, i'm using this esc with a LRP x20 4.5T withouth sensors. Dual rate on the radio, on throttle, is 50%, so the motor can to reach maximux 50% his power. With 30°*C of air-temperature and 55°*C on the track, this esc work for about 10 minutes....after it stop work and blink green light, on the manual says the esc is gone in protection. The temp on the heatsink of the esc is 70°*C, not so high... What could be the problem?

Heat sink not secure or over-amp?

what would be a good motor?

It greatly depends on your R/C and what you want it to do, I wanted faster than I could use, so I put a 5250kv 4pole in my 4WD buggy and geared it to the moon with this ESC. I have found you need a lot of room in the model for interference to die off with this ESC, I had to use my TGY i6 instead of my car radio just to get the glitches out. I'm however using the Quanum Vandal, with like zero room inside.

So this ESC is not really a great choice? Im making a 3-D printed 1/8 scale truggy

I like the ESC, very little cogging even with an 8.5T sensorless at a gear ratio that makes the theoretical top speed of my buggy reach past 120 MPH. With your antenna outside the body, and aligned with your handset, there should be no detrimental interference.

Another 5 star product from hobbyking. Good overall quality, very light and well made esc. Powerfull fan! Awesome value! I used the hobbywing software to make settings and usb adapter. Forget branded names. You don´t need branded names, I have 20 hobbyking combos at this time, they are keeping better and better. They are excellent!!

love this and the 60A x car esc's , we all know what they are but that should not detract from the fact that they are awesome , super adjustable from very quick to rather slow or anywhere in between, get the usb dongle or hobbywing LCD/turnigy LCD usb programme boxes and set up and change firmware on your pc, not waterproof sadly , no wonder they keep selling out .;-)

Nice Esc, i'm using it with my Xcar 10,5T Motor in 1/10 Touring Car with Hobbywing's V3_110930STOCK Firmware. After 5 minutes of race, Esc it's 35ºC and Motor it's 60ºC. It works very nice, run smooth and its small. Great Work HK! ;-)

For sure, a best bargain price for 120A Car ESC~ with well with Hobbywing firmware & 4 poles motor. Maybe, wire updated to 12AWG is required when the motor draws high amp!
