After selling off the parts from my old MBS Comp 95 board I am left with a hole in my quiver for a powerful off road capable board, something with enough torque that it would yank my socks off and roll away into the sunset if I didn’t have bindings on it.
The current plan is to make a custom maple and fiberglass deck for this down the line, but until then the Faultline is a placeholder
So far so good, everything is accounted for and the assembly process has begun!
For the battery we are rocking a 12s4p P42A brick battery with 30mm * 0.2mm nickel for the series/parallel connections and an ABS spine to keep it all nice and neat. It will be packed into a Pelican Ruck R60 with an LTT smart BMS so I can keep an eye on it. All of this is gonna get tucked away between my feet, thankfully the R60 isn’t terribly large so the stance will not be as uncomfortable as the Comp 95.
The rest of the electronics get packed into a matching Pelican Ruck R20 and it will be bolted to the rear baseplate so I don’t need to run so many wires across the length of the board (also I am a sucker for split enclosures). The big ticket item in there is a pair of Enertion FocBox 1.7 ESCs on a 3DServisas heat sink which just barely fits into place, I will need to do some fuckery to get the wires in there but it’ll get done sure enough. The rest of the goodies inside are a Flipsky 200A smart antispark because fuck loopkeys, a VX2 receiver so I can get that sweet telemetric data, a METR Pro for the logs, and absolutely nothing else because I am out of space for it…its gonna be tight as it is.
The drivetrain is a little bit of a strange combination, for some strange reason I wanted to have 90mm mounts matched with 72T pulleys and it’s been giving me some issues but where would the fun be if this was easy? The total setup is a pair Torqueboards 190kv 6380 motors with 15T pulleys on Boardnamics 270mm hangars with the new idler mounts (reversed of course) powering Rockstar II hubs with the MBS 72T polymer pulleys and Trampa Urban Treads. I have to use a 420mm belt and the 15T motor pulleys because there isn’t enough clearance for the idler, if one day the slot style Boardnamics mount comes out I will switch to that but until then I am relying on a perfect combination of parts for everything to fit. Also I needed to get 75mm * 10mm shoulder bolts and 16100-2RS bearings so that I can run the Rockstar II hubs, a little more expensive than I would like and I need to make bearing spacers so that I can actually tighten the axles but it works so well together otherwise. In order to have the clearance for the pulleys to not touch the mount I have a single M10 washer on each axle and it is just enough clearance. Regrettably there was an issue with one of the hangar threads right off the bat, but I managed to clear out a bunch of chips from the hole and how everything is the way it should be, no harm done. As it stands there is just enough room to not have dangerous wheel bite, I love that I can adjust the KranK bushings (I have 90a barrels in there right now and a longer kingpin nut) so that it stops just clear of the deck.
