I'm trying to do fine tuning on my wraith and having some issues I have Momba Master pro ESC Tekin ROC 412 3100kv Steering servo JR racing 9100HVT Hey OK winch controller with winch Spetrum SR410 CC BEC 2s 3800mih The rig drives nice all functions work well except. When I make hard right turns it releases the drag brake and drives in reverse, When I turn full left it releases the drag brake and drives forward. The rig does not go fast when this happens. the way I noticed it wanted to go forward or reverse when turning was by holding it in the air. Any advise would be helpful.

| Re: Have tech questions? Will answer. If your 45t is getting hot on 3s and you don't have any binding in the drive train your gear ratio is too low. Get a smaller pinion or bigger spur or both.

Ya, sounds like servo mixing. Radio reset.

whats the smallest pinion and biggest spur I can fit with the scx10ii edit: just occurred to me. I need to change the pitch.... that's how I can run a super small pinion and similar overall size spur gear. any recommendations. Last edited by intheworks; 11-07-2018 at 05:41 AM. | |

These gear ratios slow the vehicle down so perhaps use my handy gearing chart to find a gear ratio you prefer Last edited by Voodoobrew; 11-07-2018 at 08:48 AM. | |

Voodoo killing it in here faster than I can respond, lol! I've got nothing to add more than has already been said. I have a TRX4 running the TGH 30% overdrive tranny and it does make a Custom Pro 13xx 540 run warm, but not actually hot. Might depend on driving and terrain as well. A 550 is a good choice if a few extra ounces are OK, they really drive nice. The 27t 550 Torquemaster or the 12t 550 Crawlmaster would be my choice. I tend to lean crawlmaster. |

I got some feedback that 32p gears are inherently stronger so I decided to get 32p 9t pinion and a 32p 64t spur gear. I'm hoping this will take a little strain off the motor from the original gearing I had 15t pinion and 56t spur hoping if not my next move will be that 550 crawlmaster beast

any ways the new gear ratio you have chosen is double what your old gear ratio is so your truck will be half as fast on the same motor with double the torque, if you want the speed back you can get a lower turn motor and you will still have plenty of creepy crawlyness, torque and a cool motor IMO. and ash holms said the 550 motors are great, I would go with the faster 10t crawlmaster or the 21t torquemaster or 21t trailmaster myself though. | |

the transfer case is 20/26 vs 26/20 making that number .769 So previously with the 45t that got hot as hell I was running: 21.51:1 terrible 56/15 spur and pinion 36/18 trans 20/26 t case 30/8 axles FDR bone stock scx10ii kit version 36.36:1 FDR with V2 chassis stock 15t pinion and 56t spur with overdrive = 21.51:1 FDR with v2 chassis stock 15t pinion and 56t spur no overdrive = 36.36:1 FDR with V2 chassis 9t pinion and 64t spur with overdrive = 41:1 FDR with v2 chassis 9t pinion 64t spur no overdrive = 69.32:1 Last edited by intheworks; 11-08-2018 at 10:39 AM. | |

I'm running in my yeti a puller pro R 540-L powered by a Monster X on 3s, in the description i found these specs: Twelve slot stator, 180C resin impregnated copper windings 180C rated high strength neodymium magnets so should i set the motor temp cut off to 180° ? And which gearing would be recommended for U4 racing style driving using a 64T Spur and 2-speed trans? |

If you find the car is too fast and uncontrollable or gets too hot, slow it down or reduce the punch. If you don't have problems controlling it and its still cool enough speed it up. I don't race U4, but I don't think everyone's car should be set up the same in this regard. | |

The Puller doesn't have a thermister inside. Start with slower gearing at first if you dont know the setup. 180f on the can is about right for an end of the run temp with plenty of wheelspeed. . | |

if i understand correct the puller pro haven't a thermal sensor inside, so the setting in the esc doesn't matter. Tested 19/64 gearing, cause i used this gearing with the CC1410 3800kv. No thermal issues, max measured at the outside where 59°C approx 140°F, normally i can touch it by hand But this was crazy fast and i had some accidents with nice roll overs and broken rodends so i went down to 16t not tested. was just curious what is used in racing u4 with this motor, will get some other pinions next time to find my sweet spot. Appreciate your answers thx |
