    @LunchBox I've had great luck with Castle Creations products and would certainly recommend them to others.

    Castle mamba probably. I really don't see how big a jump a cheap system like a hobbywing would really do for the truck since its already brushless

    Not to dis' Castle, but don't you feel nickel and dimed by them? I sure did.
    You get the ESC and motor, then gotta spring for the fan [not included] then programming card, what am I missing?
    I'm loving my Duratrax 1/10 Onyx 4550kV Brushless. True-dat, it's pricey but all included.

    Sorry if I´m hijacking your thread Lunchbox, but the title is related to my next question. Do you have a gearing idea for a 4 pole motor 4250 kv. Right now i´m using stock gearing 18/87. It´s a trackstar combo. Do you think it can handle 15/54.?.

    Thanks
    Cobi RC

    I was wondering about gear ratios when I changed tire dia, but left gearing stock, then change gearing, "what if", "what if", on and on.
    Cutting to the chase, here's a site where you can input tire dia, spur & pinion and trans ratio to give final ratio. Hope it helps!

    I just realized that the problem i have wasn't gearing oe esc setup. I was having problems with the clutch. The new 4 pole motor turns so fast and makes the clutch slip. Do you have an idea how to solve this?
    Thanks and i wish you all a happy new year

    I had the same problem, going from brushed to brushless.
    To resolve, took the slipper clutch cover off and re-adjusted according to the instructions, with cover off and testing on a clean street [not dirt], began turning the nut down 1/2 turn, test, 1/2 turn, test, and so on until the problem was corrected.
    I'm taking the position the clutch pads will wear faster now, so tossed some into my cart to have at the ready when I cut my next order.

    Castle Creations had an "upgrade" program last year. Long-story-short; they created a list of RCs and the ESC/motor combo they recommend. Scroll down to the link "a list of more than 70 “upgradeable” vehicles", it will open a .pdf file, navigate to your Arrma for their rec.
    Good luck!
