    Apollo x18 dirt bike

    Hey, so what's your battery configuration? I'm planning on doing the same exact setup as yours but different controller and battery. I'm thinking about putting on a 20s 12p so 240 cells. How much do you have on yours?

    Yamaha YZ250F

    I finally ordered the qs180 through the original qs website. It was a little strange tho because they gave me an option to pay through this website called "wise" its basically a website that sends money to other countries in different currencies. I dont know where you ordered from but if it was...

    I'm confused with brushless motor and brushed motors. Let say I have a brushed 72v 600a controller and motor Now let's say I have a brushless 72v 600a controller and motor rated at 1200 phase amps peak. The brushed controller dosent have phase amps. Would that mean that my brushless motor...

    Yamaha YZ250F

    Yes, sorry for the misunderstanding, I meant 600a peak.. so 43kw peak? Not 43kw continuously l. For my kart, I'm not planning on racing it or anything. This is just for fun, riding around home, race some friends. My main goal for this kart is to get a good 0-60mph in under 6 seconds. My batterys...

    Does that mean that the ND721200 is to much for the motor? Because it's rated 600 battery amps and 1200 phase amps..

    Do you think that if I give the qs 180 motor 600 battery amps continuously at 72v, that it would be to much for it?

    I have my controller set for 500BA and 1600PA. Doug Why do you have it set at 1600pa, does 500ba make 1600pa? Or did you just set it at the highest number. Cause wouldn't 500ba make only like 1000pa? And jot 1600pa

    QS 180 90H vs Zero 75-7

    When I asked this question I was asking about the nd721200 and the qs 180 90h. If you had to choose a controller for the qs 180 on a 160kg shifter kart, what controller would you choose to move that thing from 0-60 the fastest.

    Just keep in mind im planning on using this motor on a 160kg shifter kart. Can you check if I'm on the right steps of planning. Im planning to use the 180 with a nd721200. For my gearing I'm simply planning on using a 14t sprocket on motor shaft, and 28t sprocket on Axle. Do you think im...

    Have you gotten any 0-60 timing on the setup? I'm also planning on using a qs180 90h motor on a shifter kart. Still thinking what controller I want I was thinking about getting a ND721200. What are your thoughts?

    QS 180 90H vs Zero 75-7

    I'm also planning on buying the qs180 90H motor. I just dont know which controller I want. Qs says that this motor is rated for 300a dc current and 450a phase current. I hear people buying nd721800 and nd721200 controllers that give the motor 1200A, 1800A phase current! Is that safe for the...

    QS138 90H VS QS180 90H

    Hey how is your build going to far? I'm planning on making a go kart using a qs180 80H as well. I'm stuck with what controller I want. It's either the nd72850, or nd721200. I'm thinking that the nd721200 is to powerful for that motor. What are your thoughts??
