| scx10 honcho no need for DRAG BRAKE?... already has drag...
i built my honcho n i thought i needed a esc with drag brake so the car wont just roll in some situations and angles but after i built it it seems that i dont need any dragbrake the car itsself already has enough drag to stop it from rolling away anywhere... does this sound ok or did i do something wrong?? Thanks! |

I don't know how the TR differs from the Honcho kit but my TR def doesn't have a drag brake.

It depends on the motor. I don't know the differences that make one have more drag then others. I do know that my scx10 will roll down a hill quickly with my 12T in it but with my 55T it will just do a slow crawl down the hill.

If your ESC does not have a drag brake, you will definitely experience rolling in whatever direction the weight is being pulled by gravity.

Gear mesh between pinion and spur. Bet it's noisy huh? Shouldn't be hardly any noise at all if it's meshed properly. If it's meshed right you can hold the pinion TIGHT, and wiggle the spur back and forth enough for the "engaged" spur tooth to 'click' a bit between the "engaged" pinion teeth without the gears moving, just a tiny wiggle/tick . If there's no play at all between the pinion/spur, you'll typically get a RRRrrrRRRRrrrRRRRrrr noise natural "friction" drag brake sorta, plus it'll put more wear on the gears and the motor will run hotter. Gear mesh goes a long way to the logevity of parts. |

disconnect your driveshaft from the axle and try to spin your wheels. It should spin freely.

Other than what they said, I was just thinking...when you assembled the axles, did you make sure to press the pinion gear all the way in?

Yupp made sure the diff pinion was pushed all the way. Ok so final solution 2 this is that i believeits my motor cuz without it it's nowhere close 2 having as much drag. It's a handwound 24degree 27 turn stock race motor thanks 4 all ur help n imput guys! Can't wait 2 get out n crawl!!!!!! |

sort of sounds like a bad motor bearing maybe. had that problem on an old losi buggy, ran fine but would slow way down when you let off the throttle. tried everything but nothing fixed the problem until i swapped motors.

if its a brand new motor then its the magnets in the motor mine does the same thing when you run it. the motor gets warm and it will loosen a bit i run a trinity 27 turn motor and those magnets are strong just keep the motor from overheating and the magnets will stay strong i dont think its the way you built your rig. i can put mine on an incline and it wont budge until i give it throttle i didnt have to buy an esc with drag brake just a good motor

and if your motor has bushings rather than bearings, it may need a drop of oil. ive run a stock 27t axial motor,brought it inside, and went to turn the wheels,it was like it locked up??? put a drop of oil on both ends,work it back and forth,and it loosened up a bit. | |
