That’s GREAT, I will give it a shot in near future, I got one of my maytech ESCs back after repair and have to rebuild my board (also need to upgrade chain to 25H instead of 6x2,8mm). Thanks a lot! So You normally upgraded firmware by USB programmer and an app (do You have any new version of it, I have the one maytech sent me)?

Thanks for posting the firmware

You guys are very welcome, its the least i could give back to this community. Now everyone can ride safely with your new brakes :wink:

I have the USB link and software from Maytech. That software is made by FVT also. So you don’t need anything else.

Is this the esc your talking about?

I thought airplane esc’s didn’t have breaks in the first place…

I think that’s the same one TB sells with SimonK firmware. If yes then it is the same.

This is the one on FVT’s page: https://m.alibaba.com/product/60403982435/SWL-HV-OPTO-120A-Brushless-ESC.html Then you just have to load the firmware on it.

Does anyone know about flashing an ESC? There are some cheaper ESCs like this:

They run the same Silabs MCU as the one discussed in this thread. I know they can be flashed with BLHeli and .HEX files, but no idea how one would go about trying to flash one with a .HGM file.

Thanks, Dude! I’ll have to try this out when I get back from AZ. I went back and forth with the sales person from FVT who was going back and forth with the engineer. I got a couple of firmwares out of him but nothing that fixed the brakes. Way to go!

Hey that’s good results. Not sure about your issues. I’m not having any with random brakes or not synchronized beeping. Try using my settings below. I didn’t like very slow acceleration. much better set to high. also make sure to set your trim on the remote properly. Also make the neutral range less if the delay is annoying. I’m using 190kv motors not sensored and a 15/ 65 gearing

I finally was able to upload this firmware to my ESCs, unfortunately they started acting weird. I’m using nano remote and I think this may be what’s causing this problem. So, when I fully break and then rapidly release throttle lever, ESCs for second recognize that as full throttle. After fiddling for many hours with throttle trim potentiometer (it’s almost completely turned to max counterclockwise position, ESCs take a while in this trim position to notice receiver and start), and setting neutral range to 3%, I don’t get this strange full-throttle-while-releasing-break action. Something like this has never happened with the old firmware.
