    Electric motor Armature repair, NEVER TRY THIS EVER! Electricity can and will kill you if your are not careful, if you have a bad armature, replace it, do not try to repair it, this only shows you the mechanics of an armature and this probably won’t last long. I ended up using a brass brush instead, the copper did not last long, and don’t forget to clean your graphite brushes with light sanding. I also put a heat resistant ring around both ends of the armature brushes cut out of tubing and glued them in, this worked good at holding the brush in place. Any time you experiment with motors they can hold a spark for a long time after you are done so make sure you watch your project for a while after to prevent any fire hazard. Again don’t ever do this just replace the armature with a brand new one, or better yet get a new tool. The cost for a new tool is similar to an armature cost, this is desert island science, for those people stranded on an island with nothing but spare parts. keep inventing’

    With the 835E, there’s no tradeoff between affordable price and performance — you get both in the same package. The going-in price is a pleasant surprise…and what’s even better is what you get for your money. It starts off with a 1/8 scale-size brushless power system. It’s an Onyx 2200kV brushless motor matched to an Onyx 120A waterproof ESC — a combo that can translates to serious air time off jumps, explosive hole shots and wailing top end for straights.

    And things only get better from there, because the 835E is loaded with what you want. Extras like sway bars. Tuning options that are usually add-ons. A 2.4GHz transmitter. Hardened steel and anodized aluminum parts — and the protection of the only free, 1-year parts replacement guarantee in all of R/C.

    The Duratrax 835E: get it — and hit it. Hard.
