Recently upgraded the rustler 4x4 brushed to brushless. Here's the first test flight with the original 10 tooth pinion, 54 tooth spur and a 2s lipo...
Definitely faster but not by a whole lot, need to get a gps for more accurate assessment. Motor is getting very hot, can only tolerate touching it for about 5 seconds, esc and wires staying very cool compared to motor...
Now that i'm in too deep, need more speed, gonna next take it up a tooth with an 11 pinion. Also got an adapter for adjusting the gear mesh, set it and forget it and a 3s lipo to boot. I've ordered a heatsink for the motor but its backordered, good chance i'll experience overheating issues but planning to cut out windshield if need be to allow some better air flow...
Noticed the stock plastic center driveshaft had a wee bit of a wobble so was going to upgrade it with a aluminum shaft. After disassembling the plastic shaft, i discovered the steering apparatus was rubbing and had worn the plastic shaft some. Being that the aluminum shaft diameter is larger than the plastic shaft and i see no adjustments i could do without reducing the already limited steering radius, i'll continue to use the plastic driveshaft till i figure out an acceptable solution. Last but not least, some new lug nuts...
Looking forward to the next test flight, will edit in update asap...
