This is the Holmes Hobbies Torque Master BR-XL Brushed ESC. Designed and manufactured in the U.S.A.! The TorqueMaster BR-XL is the hottest brushed motor ESC for rock crawling applications. With a 80 amp continuous rating and a huge input voltage rating of 28.8V, this ESC has been designed from the ground up to meet the rigorous demands of low speed control and high speed power giving even the most power hungry drivers what they want. A 5 amp, 6 volt on board switchmode BEC delivers unbelievable servo power at any input voltage.
The TorqueMaster arrives factory programmed with auto lipo LVC, full drag brake, instant reverse, and 100% reverse throttle settings. These settings can be easily altered with stick programming, and are fully computer programmable via Castle Creations Castle Link with instant firmware upgrades.

Features:

• 1 year warranty
• 2s to 6s lipo input
• onboard 6v 5a switchmode BEC
• 46x34x20mm
• 38 grams (with battery wires)
• Brushed only
• 80A continuous, no single 540 motor limit
• Desinged and manufactured in the U.S.A.!
• Super easy Stick programming
• Computer programmable via Castle Creations Castle Link with instant firmware upgrades!
• Reverse and brake adjustment
• Regenerative Drag Brake
• Active Hold Brake (The Holmes Hold!)
• Quiet mode

Are you saying A-Main is the evil empire? :lol:

I dont get it... CC has been making the HH ESCs for a long time.

I have a question though- is it "brushed only" just because it's missing a wire? Could I open it up and solder in the third wire and run a BL motor with it?

*crawls back under his rock...*



:sleep:

No it's custom designed for brushed iirc

Awe, bummer. That'd be a sweet deal if I could just modify it to run BL. :yes:

It's aimed at rock crawlers. :)

Personally Im going to use a MMPro for mine; that way I have option of brushed, or sensored/sensorless brushless, or can use it on something else. Probably take off the fan as the loads, etc. shouldn't be high.

Just be aware that the MMPro's BEC won't do anywhere near 5A continuous...

And this is an issue with? Not had an issue with it in my XXX-T or SC10, granted both using standard digitial JR91000S servos

Well, seeing as how the HH/Castle ESC has a 5A BEC, I just wanted to mention that the BEC in the MMPro is not comparable. Its output voltage drops significantly around 2.25A. In 1/10 scale vehicles, it works OK, but many have had problems with strong servos and/or in larger vehicles.

Ah, yes. Well, in my case, its going in an 1/10th rock crawler, so think things should be good. But definetly in an 8th scale vehicle you are probably right.

Would be interesting to hear from Rob on how the HH is different than say a Sidewinder SV2 which it looks a lot like, other than the 5A BEC and being only brushed.

or when you use bluebird/cheap servos....

I would say the cheaper servos don't help but I don't know if that's the whole problem. It's a 3amp bec which should power most any servo out there. I have noticed the spektrum receivers are finickey with voltage fluxtuation but my mmpros have ran a few diferent digital servos just fine. They seem to really like the futaba brushless servos(me too!). The only issue I have had with mine was when I got my jammin sc with a ballistic 4.5 the rx would reset on a full throttle luanch. Never got it any other time or with rapid or locked steering inputs. A glitchbuster later and everything is good.

This speedo makes me want to break out the lathe and get some mods around 10-12 turns and relive the glory days. Oh yeah I can do that with the mmpros hmmmm....

Not sure what servo your going to run in your crawler but most of todays 'comp worthy' servos, draw well over what most internal becs can handle (the HH being the only except but it's still only 6v). If your running 7995, 7950, S9157, 7980/7990, 7954SH, 8711 your going to want a CC bec minimum for power wise. Remember crawlers work servo's A LOT harder than other applications. Plus most of those need around 7.5v to get the most out of them:yes: Also I am pretty sure the HH is a completely different board to the sidewinder original and SV2, the only similarity is the sidewinder case. Which is shared with a number of ESCs now.

While I admit to being a bit of a newbie in crawler world, I think all those are complete overkill for a 10th scale crawler. Personally I was just going to use some non-high voltage servos I had for 8th scale nitro applications; should have more than plenty torque but where it can operate on internal BECs.

I doubt its its own board unless its the same board as the new Axial ESC that is a rebadged CC; otherwise the run size would just be too small for its own board.

In comp crawlers it's around a minimum 30kg (400oz) of torque, anything else is just a waste of money. Might seem like overkill but after you go up in torque you can never go back. I know for a fact that JRH has commented and said the only relation to the sidewinder is the case. I don't fancy going through the entire RCC forums to find where he posted that, but I remember it clearly. Neither the sidewinder or the new axial can handle 6s nor come close to the rock crawler specific programing or physical features of the HH they are different ESC's. The only pictures I can find right now of the board on the HH itself are a very very original proto that only recently gave up the ghost. Not much good for ID in comparison the a sidewinder.

Edit, I've had a bit more of a look I can't find any pictures of the brxl board for comparison sorry. Also sorry if I come across as a bit of a know it all. And finally don't underestimate the popularity of the BRXL, it's a very common ESC in crawling circles.
