Any updates for your RaceBoard?
bushings, esc… ?
That’s pretty soon to plan a trip out there…
Installed the mamba XL x on the raceboard. Very pleased with the tuneability and performance of these…
Bushing wise on the raceboard the fast and large turn setup is satisfactory. The under 20mph tight turn I have yet to dial in… Will have that dialed in before the Colorado race in April…

Racing season is upon us… Skateboard racing slicks. Couldn’t get these to slide at Spd2, don’t think it will be much different at the Colorado Race in Colorado Springs Apr 8. Stuck down grrrip!

Look light and fast MoeBro! 
Sign me up for a set 
Would anyone here be interested in delta/WYE switching? Ima about to assemble a test circuit

It’s small enough to mount on a board
That track is made for these! Still wish I could go.
What’s keeping the rubber attached to the rim?
Stripper glitter and beer

Bonding agent holds it together, . wheel has 1/4" hard density foam with a rubber sleeve overlay. Weight is 9oz and have been tested to 57mph.

Hey @PatRocks. I will be in Colorado Springs on the weekend of April 7 racing. Also gonna make a run at Pikes Peak. Would be a good place to make a run with your quad build. Im your huckleberry.

4.5mile uphill on a 40mph setup at a down hill event happening this weekend. 1131watt hr stack and pack.

okay, so how do you guys build for speed… i want to go fast and am not satisfied with my speeds now
EDIT: how do you guys build to go fast safely
It’s never safe to go fast. For a start it’s not if you fail it’s about being prepared for when it does fail. Mitigating hazards: Heat is the enemy. Any time your pushing the limits of electronics your exponentially speeding up the clock for component failure. In electronic equipment there is no Bullet Proof. Midigate equipment hazards by overbuilding your delivery system. I like to use the 65% zone as a safety factor. Just pulled data from my 2mile uphill pass at Tepe’s & Tacos DH event on a 40mph setup. 128deg f on the ESC was as hot as it got. Also motors need the same Safety Factor, heat IS the killer. The more watts your motor is capable of handling the cooler it will run. Every board running 40mph should have 8kwatts available. Do you need it to go 40, No, but the failure factor goes way down. Mechanical setup: sketchy and fast isn’t a good combo. Plenty of bad equipment out there that has no business going over 25mph. “Guys! Heads up. Your high horsepower Speed Trampa builds don’t work!” SPEND THE MONEY… buy precision trucks with proper angles and put them on boards that don’t tortionally twist. Speed wobbles come from the rear… I am building new board for breaking the world record and have deceided to test a front drive setup. The rear setup is the key to making stability at speed. By taking the drive off the rear it takes that dynamic out of the equation on the rear axel. Will be testing this theory soon enough…

Thats a good idea, and i kinda figured thats where the wobble came from… I tightened my rear trucks and use the front for steering now (granted i can’t take hard corners w/o forcing a power slide) and im running a board that the calculator says has a loaded speed of 30 mph but i havent gotten close to tht at all im using a single drive (dented my can on my other motor) TB setup, 218mm trucks and all… I have my own setup that I’m trying to get machined but I can’t afford it at all it’s a full suspension board w/ 8" pneumatic tires 4x4 hub motors… It’s only in paper rn but as soon as I find a machinist that’s willing to make them affordably so I can test them I want to start selling them
