Holmes Hobbies BR Mini


The TorqueMaster BR Mini is brand new and ready for your tough tasks. It is the shrunken version of the BR-XL- no case, no heatsink, and a smaller footprint. Perfect for weight conscious crawlers, robotics, and off road trucks. It has been designed from scratch to meet the rigorous demands of low speed control and high torque density.

Comes stock with Auto lipo LVC, Full drag brake, instant reverse, and 100% reverse throttle settings.

1 year warranty
6v to 25v input
30a continuous, 80a burst
6v 0.5amp linear BEC @ 7.4v input, external BEC suggested for all installations.
28 x 28 x 6mm PCB
8 grams (without wires)
Brushed only
Stick and Castle Link programming compatible

Reverse and brake adjustment
Throttle and Brake curve adjustment
Regenerative Drag Brake
Active Hold Brake (The Holmes Hold!)
Quiet mode




Useful in competitive RC Rock Crawling and Off Road Truck environments, robotic and servomotor applications, and ultimate proportional winch power packages. The TorqueMaster BR Mini is THE brushed controller! Get yours today!

First batch is now in stock on the site. Expect these to have the same burst performance and drag brake strength as a BRXL, but in a smaller package that is thermally limited by the size of wires, motor, and battery being used. ON resistance is the same, so the amount of heat will be no higher. But, a smaller size causes temperatures to be higher without careful use. Tune at your own risk!


The controller listed for sale is not protectively coated to allow for easy motor and battery wire installation. Users will need to do this for best operation. Plasti-dip works if conformal coating is not available to you. We will shortly have dual controllers and wired controllers listed on the site, they will be conformally coated.



My recommended installation is with 16ga or 18ga wire in USRCCA style competitive situations with limited run times. You can run any single brushed motor from Puller 550 to 400 frame sizes, but heat must be watched on larger and lower resistance motors. 180f max is safe for limited time runs.

In longer driving situations, like scale rigs and G6 competitions, larger wire such as 13ga or 12ga must be used to wick out heat and provide higher thermal mass to the system. Any single brushed motor frame sized 550 and smaller can be ran, but heat must be watched and gearing adjusted to keep temps below 160f. Your rig weight, gearing, and throttle finger will determine how hot the system gets.





This is a high performance product, not a stock replacement part intended for a specific vehicle. As such, you will need to find your own system limits for each system. Happy tuning!

Awesome! These are my next esc purchase right here.

[STANG KILLA SS]

yes yes yes!
ive got 3 BRXLs im running now, and plan to replace them with these.
awesome work John!

[ittybitty]

Glad these finally showed up...gonna have some in my rigs VERY soon!

[JohnRobHolmes]

In servo / winch / mini applications the main capacitor can be reduced in size. We are working on instructions to describe this and multi unit bricks.

[Hittman]

Awesome stuff. I am glad I have one coming. Will you have some with you at Nats? Because I need to pick up a few more

[eric113]

For scale applications, are you going to offer later on...

1. Cased,heatsink,waterproof

2. Non cased, heatsink, waterproof

?

[JohnRobHolmes]

We will offer waterproofed versions with 13ga wire attached for scale applications and users that don't want to wire and coat themselves, it will just be heatshrink covered as a final protective layer.

There is not a plastic cased or heatsinked version planned at this time. Because of the small size the thermal mass does not increase much with a regular heatsink. We may look into doing an extruded case for protection after the RTR scale version is settled.

[chevotafun]

Awesome can't wait to get a set of these.

Would you offer these already smashed together for a extra cost?

[bigstu]

Looks sweet..
Any thoughts on a combo?

Two mini's, smashed with a CC bec, and a pair of matched pullers ???????
Sounds like the ultimate comp crawler combo right there..

[xigtc]

Pretty fricking smart!! I think I'll be picking one up for my next build!

bingo. want!

[JohnRobHolmes]

I will start fleshing out the other build types about the middle of September after Nationals and after we have moved Volt Riders to the new location.

[Olle P]

What parts get heated? One might consider using thermally conductive glue/tape to stick the ESC to part of the frame or so for better cooling.

order placed for a set of 2 for my berg V1

waiting for any small engine and very powerful

thanks john ..

His Puller 500's fit that bill perfectly

[ittybitty]

Got mine in the mail today. Installed 2 of them in the XR...they're buttery smooth just as they should be...and of course they pack more punch than other ESC's

Great work on these controllers John!

[JohnRobHolmes]

A heads up for you early users, we have seen some issues where two units tied together run hot and have some amperage issues. We are tracking down whether software or hardware issue and will have it resolved asap. This wasn't an issue in the protos and doesn't seem to be affecting all production units, it has been difficult to pin down so far but we will get it solved whether it is a simple firmware update or new units being sent out!

Edit- 1.10 Firmware has a bug, do not use Hold mode.
