While last year's Mud Man wasn't the best for taking out the wheel. The year prior was a blast. Between passing sand storms I was able to get a lot of good rides in. 240 miles of time out there in 2 weeks.

I found that there was two types of dirt surfing out there. The hard pack playa and the sand traps. Both were fun. The sand traps added a whole new adventure at speed. If you cut into one, you went from complete control over the board to actually feeling like you were on water as you sailed through it. No control and you had to just learn to go with the board. Such fun.

After a number of days learning how to surf playa, I decided to go for a speed record. Burning man only allows 10mph anywhere, but Shhh! I won't tell if you don't. I had figured out my course and eyed it for any holes or dips. Who wants to hit a sudden hump at 25+.

I was able to record a pass at 30.1mph on a stock GT.. on playa. Felt pretty good. The whole rest of the week was filled with a lot of confidence out there on the dirt and I became a runner for the camp to get supplies. Burning man can't really get upset at something they can't catch. Right?

I did fall once. Stupid slow speed sand trap fall. I don't recommend falling on playa. The alkaline of it gets in the cut and keeps it from healing. Kind of sucked, kind of didn't care for the rest of the trip.

All in all, great time.

As the title says. I am looking for a custom front control box. The goal is to fit the maximum space available within a rear bang bumper moved to the front.

I know what you're thinking. Why in the hell is this guy adding so much room to where the controller goes.

Well, another 18-20 batteries is why.

There's a guy on the YouTube who has figured out how to fit another set of 18s 21700 batteries, a BMS, and controller into the front of an XR, using a badgerbox torque box in the front... Why on earth hasn't anyone done that to a GT with the added room it has.

I know there are connector details that need to be addressed, configuration considerations, deletion of the front handle and a lot that goes into this design. That's all fine with me.

I can cut and shape sheet aluminum for the heat sink, I can solder and build a battery pack. I understand the wiring configurations. I just cannot design and print a box.

Anyone have any know how and want to do something crazy. Anyone who can work on this project with me can keep the design files after to use at their disposal. Sell prints, etc. id like to just fund my own adventure.

Details people will want, I'm sure.
This board is for downhill street. I've found that even on a vesc, the braking capacity reaches it's upper limits on the hills I have. This means turns and slowing down becomes dangerous. I mean, safety third, am I right? But still.

I'd like to see if I can fit a 30s2p 21700 split battery in a GT, with something like an x12 or any other controllers that can handle the 130v.

I've had more then enough experience at 25-30mph on street and am just looking for a bit more control. Not necessarily mileage.

I'm absolutely open to other ideas of what to do with my extra, dead GT. I've heard the GTV is nice but again, braking power has been a limit. I can't just tail slide the bumper away, all the time.

Thanks in advance, and again, if this seems crazy, trust me, I know.

@franko 5...10...30.. same thing, right? Ha.

Ya, luckily I did not see any one wheels stuck in the mud but that thing went away when the rain started.

I got used to riding really slow, so I'd ask people if I could come play their games in their camp bar while staying on the wheel. Became fun to do dildo toss while rolling.

@lemur oh man, that's some heavy lifting. Good creativity though. Oneans paperweight is another's one wheel adventure.

@biell that's true. I haven't really considered the exact battery configuration beyond wanting to do something like a 60cell combination.

There is a tonic x12 that handles 130V. It should be able to handle the voltage in and out without much issues on the 12 mosfets.

@biell said in Needing custom Gt Control box:

@highspeeddirt Have you found a VESC which will support that kind of voltage? I didn't think there were any that went that high. Also, have you thought about a 20s3p configuration instead? The 20s3p would also give you hella torque from the extra current it would support.

After looking at how torque and motor braking works, I think you're right with the idea of 20s3p. Plus, I would up my total miles by a third, at least.

Granted on this slope, I gain 2% Regen every .4 miles easily. So with a 7mile circuit, I can't start this track with more then a 50% charge on my battery.

@franko there definitely was. It was fun, granted it happened during a dust storm.

@lemur that's about what I figured. The 30S version seems appealing for my current build interest. I do a lot of downhill riding. I started out on a long board bombing hills. Speed doesn't scare me and my ankles are in great control of a one wheel, even with a high psi.

I'm looking to build a setup that can handle a lot of braking power. Coming up to a corner at 30mph and not knowing if trust the board to stop or tail slide through the turn is a bit concerning.

I have a 20s2p 250r GT that I am looking to upgrade from. Even with that setup, I can't seem to get it to fully support the amount of control I need for the corners.

I'm looking to build out a custom controller box to fit an extra 20cells and possibly run the x12.

@franko ha, ya I only ever grab one if someone else wants to go get one. And everyone I'd run into with a one wheel would tell me where the meetups were. I killed a battery sometimes twice a day I was on it so much.
