Those motors are reversible outside of software, you just need to re-order the pins of the hall-effect sensor as well as swapping around the blue/green wires. It was being so weird because it was trying to spin, and the sensors report that the motor is spinning the wrong direction so the controller freaks out.

[@ProdigyAutomotive]

What kind of motor is this? I'd like to price one of those electric setups

[@Hellsong89]

@@ProdigyAutomotive Kit alone is around 1500$ to 2000$ for 11kw kit depending on battery you choose and closer to 1K$ for less powerful ones. Its cheaper than some kits i have seen but least for me i dont have extra income to throw 1.5k for racing go cart and 2K for electric setup, when you can get really good daily driver for that price and proper road legal dirtbike or get small diesel crate engine into cross cart frame, witch will beat this in utility in any day.

[@OverbuiltByHenry]

Guys! When you want to reverse the direction, you need to change two phase wires and two wires of the hall sensors if you want to do it the "long" way. The short way is to reprogram the controller (as you mentioned), changing the correct setting (indicated on the programming software) will make the motor spin the other way. Trust me, I've done it both ways.

[@rendaddy_]

surely the company they contacted suggested that first

[@esqueue]

@@rendaddy_ Just the way 3 phase motor works, that would be the solution. The fact that they didn't suggest it means that they didn't know or didn't want any mixed wires. All they will do is connect the controller to a computer and program it the correct direction. All my cheap controllers can work by switching the wires and my decent ones can very easily be programmed via adapter and USB cable. This is universal.

[@agentcrm]

@@esqueue I'm guessing it's a liability thing. It's far safer to say send the controller back, that minimises the risk of damaging hardware and having other people see the video and hot wiring their own motors.

[@ericdeangelis7496]

I know this was driving me NUTS!! I'm here wondering where's Ethan to tell them to reverse ANY two phase wires and BOOM problem fixed!

[@aviandooley3466]

Pro Karting driver here, if yall ever track that kart or do some fun street stuff, I recommend trying to get Mojo D5 kart tires if you have a 7 inch rear rim, or Vega Blue tires for 6 inch rims. It might be very tricky getting a hold of these tires as they are used for professional karting and they are pricey, but trust me, for a kart with that much power it would give it good grip

[@MarkBlance]

It's cool to see Will taking on more projects. It's also cool to see you guys doing stuff with electrics. Speed and power don't care about their source!

[@TheRealAlpha2]

The best thing about these little builds is how approachable they seem. Like a motorcycle engine might be cheap and easy to obtain, but it's so friggin' heavy compared to a small electric motor and battery you could almost slap on anything with wheels in a couple of days and get obscene speeds. (well, assuming your motor controller isn't the wrong way around... Also: Edited for typos I didn't notice originally...)

[@AussieDaz87]

I wonder how much the motor and battery weighs compared to the 2-stroke engine a fuel tank. For something this small there probably isn’t much difference

[@maynarddrivesfast804]

​@@AussieDaz87I'd imagine the weight of this electric setup is probably really close to like 125 or 250 2 stroke engine with the flywheel/stator attached (45-55lbs). However, the torque that this electric motor can instantaneously produce makes the beefy powerband of a 2 stroke feel like a 49cc gas engine in comparison. Seriously, anyone who rides bikes or karts owes it to themselves to try out a comparable electric powered setup. The G's you'll pull with good traction will blow your mind.

[@johnsherby9130]

@@AussieDaz87honestly power to weight is probably better with a little 2 stroke but the torque on anything electric is so damn fun

[@LordHolley]

This video could not have come at a better time! A good friend of mine has decided he wants a go-kart track in his backyard. It will have some elevation changes and cambered turns, etc. It should be epic! but we can't use gas carts because of the noise (friggin neighbors!) I suggested finding rough/retired shifter karts and put in electric motors. I don't think he fully got the concept. I'm definitely sending him this video. This thing you're building is overkill, but it's the right idea.

Still wish you would build an electric snow cross-cart with tilting battery pack over track so you don't have to lean (can do "wheelie" sitting comfy up front while able to turn+ can ride steeper slopes) The design has been tried in the past but using the fuel source weight to solve main problems (tilt/lean) is something nobody have done.

@@MADEINNSW The level of control they appear to have, the power curve isn't set correctly. It seems nearly an all or nothing response, with not enough ease-in.
