Default Small, light 4s capable BRUSHED ESC

Does anyone know of or can recommend a small, light brushed ESC capable of operating on 4S?

Holmes Hobbies BR mini will handle 6s and is programmable with a castle programmer.
I've had my castle creations sidewinder micro and mamba micro pro on 4s in the past, not sure if that's still possible on the newer sidewinder Micro 2 and Mamba micro X

I've been wondering if the micro X would put up with 4S, ratings are usually on the safe side of things. I wonder what the test would be for this, run it and check temps? I'm really not sure.

BR mini is all that comes to mind for me too, its a de-cased BR-XL. The regular BR-XL isn't all that small but if you need the extra cooling it may be worth a look too.

It will not explode if you plug 4s into it but we have it locked out in the firmware because continued 4s use causes excessive amounts of heat and can prematurely damage the ESC.

Ok thanks Robert.

I just tested this and the Micro X will not start up, I just had to check.

I love the daring attitude!


I think the Holmes may be the only small ESC that can handle 4S. I haven't tried that ESC.

The old FXR with a cap upgrade and external BEC was a setup for 4s back in the day wasn't it? However Like the older castle micro , unless you have one or get a good deal for a used one you're probably better of getting a Holmes Mini and running it under rated

Thanks for the info. It looks like the BR Mini is the only viable option. Unfortunately, it's currently out of stock. Just in case you're trolling through this thread, any idea when you'll have these back in stock Mr. Holmes?

I don't think the FXR could do 4S.

Setup stock notifications at Holmes and RPP with your email. That's how I got my SHV500v3 servo.

You could use 4s on a Tekin FXR with a cap mod, again not worth it in this case unless you already have one. There are other threads, but this came up.

Sorry, I misread your post. Missed the upgrade part. Tekin discontinued the FXR series sadly. So, like you said, it's only a good mod for those that already have them.

do the crawler motors (20-35t axial/HH whatever) handle 4 cells without issues?

^^^^^^^
My xl5 esc runs 4s. That is the only test I've done. It's the older big heatsink style. A few have told me to run a Bec just in case, I have not grabbed one yet. It's big, but if you remove the case and coat it up, I'd bet it would get a bunch smaller. No drag brake

I stripped all the unnecessary crap off a pair of WP880's and got them down to 40.5g each (with wires for a single motor, no heat sink.) They're still big compared to an FXR/BXR or BRmini, but not AE5 big, and it happily runs 4s. Decent BEC to boot. Heck, for that matter, I used to run 4s through my AE2 (and I've read of others getting away with 6s, I never tried) and I'm sure you could at least partially de-case one of those? I know that "small" and "light" are relative, so what are your goals and limitations?
