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 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.
