Hi guys I'm new here and finding the site very interesting.
My son has a Typhoon and his esc has stopped , reading this thread it seems to be a common problem so my question is what's the best esc replacement brand and model ?
I have the Outcast and burnt out my ESC playing in the snow. The stock ESC is only water resistant, not waterproof. I replaced it with the EZRUN MAX 6 160 AMP BRUSHLESS ESC. I had to solder different ends on the ESC so that it would plug into my motor but everything works great.

I had the exact same issue and it ended up being my ESC was in NIMH instead of LIPO mode somehow, solution: hold down the button- turn on car- wait until a green beeb- release button- ensure you are on option 1 via one beeb as this is LIPO mode, option 2 is NIMH

I've seen a number of posts on this forum asking and talking about various issues that they experience with the BLX ESC that is installed on a few different Arrma models. The intention of this thread is to gather those random posts into a singular thread to assist future readers with determining the potential problem that they are experiencing.

Fellow members, if you have had an issue with your ESC and have determined the solution, please add a detailed description of your problem, troubleshooting steps, and ultimate resolution. @WoodiE or @Unusual RC, if we get enough different use cases, we may want to make this a sticky.

Here is an overview of my personal experience that I had with ESC issues:

Model: Arrma Talion BLX 6S BLX

Age of model when problems started:
<1 month / <2 hours' runtime

Type of driving:
In snow, no bashing

Type of battery being used:
LiPo 4S

Description of problem:


Initially, the Arrma Talion would stop in the middle of a run, the motor would stop and twitch for a very brief moment, the ESC would beep twice, then the motor would usually start working again. Over the next few runs within 24 hours from the initial issue, the problem occurred more and more frequently. Finally, the Talion simply stopped working. The blue LED would flash four times, pause, and then repeat the cycle (blue light is supposed to indicate low voltage). No motor twitch and no beeps. Note that during the whole process the radio and steering servo were working as expected.

Troubleshooting steps:

  • Swapped out four different LiPo batteries
  • Tested each LiPo with a voltage meter to ensure that they were charged
  • Checked connections, especially the T connections
  • Dried and cleaned all areas by the motor and ESC
  • Tossed the Talion onto it's haunches from 5 feet up (this actually worked a few times when it was still occasionally working - apparently, the jolt was doing something)
  • Let it sit overnight in a dry, warm space
  • Got upset and threatened the Talion that if it didn't work right, I would leave it out in the blistering cold overnight (yeah, that didn't work)
Actions taken:
  • Post-troubleshooting - called Arrma Customer Support, explained the issue, and they requested that I detach and send both the ESC and motor for diagnosis and fill out their form to describe the issue again.
    • I shipped both devices to Hobby Services (with a completed form) and it arrived there on January 4th, 2016
Ultimate resolution:
  • I received a replacement ESC and motor on January 13th, 2016 with the following notes:
    • ESC was found to have programming issues and has been replaced
    • Motor was making screeching sounds and has been replaced
Additional notes and/or recommendations:

I had no idea that the motor was making "screeching" sounds, so I'm quite glad that I sent in both devices. Also, even in the middle of their busiest time, they were still able to turn around the warranty service in one week (excluding shipping time) - that's pretty incredible!

Tips for other users:
  • Check the battery in the car/truck first - make sure that's not the problem
  • Check the wires and connections from the battery to the ESC to the motor - make sure that they're secure
  • Note if the ESC's blue light is flashing. If this is the case and you have validated your batteries and connection are not the issue, you may need to call Arrma Support.
Can anyone tell me the toll free number for arrma customer support??

Ultimate resolution2: i disassembled the esc and found a 3mm long capacitor missing while comparing a photo of my board to another one. Come to find out, I’m missing 2 more pieces. Let me order those.
