    Has anyone tried using a differential?

    I have had trouble finding big enough differentials for mountain board use. I am sure that they are out there. I just don't need it for that use. Sorry. If you have any questions let me know.

    stuff

    Gimbals would work except they would get hit by stuff and break. I have thought about it and they simply dont have the ground clearance. Your on the right track though.

    Legal?

    I use my board all the time and go like 18mph on only 350w. I mean you could current limit it to 200 prob go like 15 and not get in trouble. Just an idea...

    DUAL E-MTB BUILD

    If you are willing to shell out that much money for a speed controller I would get a kelly controller. I have had these crappy hobbyking ones blow up on me many times. The kelly controller is the real deal. Pick your flavor http://kellycontroller.com/PWM-Motor-Controller.php

    Has anyone tried using a differential?

    I think 4wd would be cool for winter purposes.

    Has anyone tried using a differential?

    You are right the outside diameter of the housing where it is rounded is 1.8 inches, it can be cut down to 1.366in with out any problems I just left it thick cause it looks nicer rather than skimpy. I also think this is a premium product and should cost more than a belt drive system one because...

    Has anyone tried using a differential?

    Thanks man, I dont know whats so complicated about this. It is hard to make and it was difficult to design in such a way that would work. Because on longboards there are forces that want to pull the wheel out and push the wheel in you have to make sure it wont pop out. and make sure no pressure...

    Has anyone tried using a differential?

    I tried reading all your posts and this has gotten off topic. I don't think you guys understand how this works. I will try to explain this as best I can. The only reason the differential is good is because you can drive two wheels with one motor. I do think that on turns the differential helps a...

    Has anyone tried using a differential?

    you are correct you will lose traction but its the same as if you didn't have an e board. I don't really know what you are saying anymore so.

    Has anyone tried using a differential?

    Thank you for posting that video I was going to but I posted already and i was like w/e people might understand. THE MOST efficient is to have one of everything, one speed controller one motor one battery. Every time you add a component you lose efficiency because everything isn't perfect. And...

    Has anyone tried using a differential?

    I understand what you are all saying. Look at it from not a electric longboard, but as a car or something. If you turn the outer wheel turns faster than the inner wheel. We can agree on this. It doesn't matter which way it is facing or fwd or rwd. It could be more efficient to have two motors...

    Has anyone tried using a differential?

    you can use it on either truck the beauty is you just flip two of the phases and it becomes fwd or rwd. I think that there is a difference between the two. Fwd sort of pulls you along and if you don't have as much weight in the back then if you accelerate to quickly then it skids out. Rwd is...

    This is for scale the differential in the middle is the one in the link and also those are 90mm wheels.

    Has anyone tried using a differential?

    all it is is the differential, and the differential is more efficient then a belt drive, probably like 10% or more. http://www.ebay.com/itm/HPI-Trophy-Buggy-Flux-3-5-DIFFERENTIAL-Front-Rear-Diff-Pinion-Case-1-8-101077-/371130515940?pt=Radio_Control_Parts_Accessories&hash=item56691a41e4

    you dont make it you buy it from a company that makes 1:8 scale cars.

    Has anyone tried using a differential?

    I am currently on my version 3 board and might finish this week. There are tight tolerances and i screw up, haha. Anyway I will post pictures when i am done but I hope to make something out of it but if nothing comes of it, it will be my last build.

    Has anyone tried using a differential?

    Its like 20 dollars for the diff, and another 60 dollars for another motor and another 60-80 bucks for another speed controller. You will lose the efficiency in your motor controllers more than the gears. so you are looking at another 120 at least in additional electrical components. I think...

    Has anyone tried using a differential?

    it is a 1/8 scale truggy? Differential, also that motor was WAYYY to big for anyone. I fell off of it 2 times cause it had way too much torque. I had to replace a differential after about six months of abuse IE not current limited controller. I really don't think you need 4wd. I made this in...

    Well here is a teaser, this is my version 1. Let me know what you think. Feel free to ask questions.

    Has anyone tried using a differential?

    So you are saying you have never seen it before? Cool I have devolped a way to do it and have been wondering if anyone has done it before. do you think people would be interested in seeing some pictures?

    Has anyone tried using a differential?

    Hi, I am new to the EV thing, I was wondering if anyone has ever seen anyone using a differential with one motor to power two wheels on a longboard? Also what is the best system in an ideal world to power a longboard, Direct drive, belt drive, Differential if it was possible? I want to build a...
