    Go for a higher pinion, the motor can handle it. I'm working on the gearing for my sc8 to do the same. Love the idea!

    Sane people are boring. I'll be watching this for sure. Here's hoping you break 100, and it doesn't break your car. :)

    Small update!

    I hit a small roadblock in the build. For some reason I thought that the new esc had a mounting point on it, soo I have to order one more thing. I need a esc hold down for a e-revo, and there are two holes in the frame to mount it. I will do as much as can for now, and I will post more pictures when I can. Does any one know where i can get a GPS speedometer for this thing?

    Picture time!!

    first this is how the electronics will be setup! the recever will be behind the front shock tower
    IMG_0199.jpg IMG_0200.jpg

    this view you can see the hole for the hold down that i need to order tonight, this thing is huge!
    IMG_0201.jpg

    And the last thing i still need to figure out is this
    IMG_0205.jpg
    that tall stack of 2 batterys, the traxxas extended mount is not tall enough for 2.

    All my shafts will be here tomorow, then i can get it all put together and wait for my hold down to show up, and start pricing 6s 4000+mah 40c+

    And i think im going to get the low center of gravity kit as soon as i can! :)

    I thought a higher KV motor gives more top speed? Correct me if I'm wrong?

    All depends on the voltage you are planning on running. The higher voltage motors usually have a slightly lower kv

    your right if you dont change the voltage, but in my case im going from 3500kv at 11.1v =38,850 rpm to a 2650kv at 22.2v =58,830rpm the kv rating meens a 3500kv motor spins 3500 rpm per volt.

    I like what you are planning, insane is our middle name...lol...

    Please correct me if I am wrong but from what I understand you should never run a BL motor over 40,000 rpm so your 3500Kv @ 11.1V is near the limits of the motor? Is this right?

    Dean

    I ask because I plan on running a 1800Kv on 6s 22.2V which will give me 39,960 rpm in my boat (secret project keep your eyes open vid comming soon...lol...)

    it depends on the motor, the traxxas motor has a max of 50,000, the Neucastle motor has a max rpm of 60,000 and im going to push its limits!:psychotic:
