2 speed transmission vs 2 speed transfer case Hey all. New to the forum looking for some advice. I have a Redcat Gen 8 PACK kit, and would like to install some type of high/low selectable gearing. With no direct fit option, some type of retro fit is in order. Options are A: Retrofit 2 speed Traxxas or Axial transmission, or B: retrofit generic 2 speed transfer case ie... Helios. It seems to me that fitting a transfer case would be cleaner and require less modification. What is everyone's thoughts? ANY advice would be much appreciated? What would be advantage / disadvantage to using a 2 speed transfer case vs 2 speed transmission? Is one way more practical, suitable, desirable? Thanks in advance!!!!! |
Re: 2 speed transmission vs 2 speed transfer case Or Option 3, go brushless for a wider range of speed. |
Re: 2 speed transmission vs 2 speed transfer case I'd go with the t-case. I think it would be a bit easier overall. There is no practical difference between a 2-speed t-case or trans, you'd never know the difference "behind the wheel" |
Re: 2 speed transmission vs 2 speed transfer case unless the gear ratio is different enough, it's likely better to move to a Sensored ESC/Motor combo. |

Re: 2 speed transmission vs 2 speed transfer case Not an easy retrofit. I shoehorned a different single speed in there, but going much larger (2dsp is about double the size) is a bit tough. That's a big, bulky skid, lots to trim out. https://i.postimg.cc/yd1pKQ3f/20200926-175904sm.jpg |

Sensorless brushless motors are typically used on go-fast bashers, and racers. Not to complicate things TOO much, but there is a sensorless brushless motor type that does work very well in a crawler - but the motor type is different, it's known as an "outrunner" and the outside of the can spins rather than the inside. However, they are quite noisy unless used with Holmes Hobbies new Silent ESC. The Holmes Revolver is an excellent example of a crawler-specific outrunner motor. That all being said, a sensored brushless setup will have a much wider RPM range and typically removes the need for a 2-speed. |

Re: 2 speed transmission vs 2 speed transfer case Depends on the transmission. Some are more compact than others. The AX2 is somewhat bulky for example, while the TRX4 unit is a little more svelte. RC4WD makes one for the trailfinder (R3 Trans) that would probably be your best bet since it mimics the layout you already have, though you'd have to come up with a way to mount it. |

Why did you replace the stock transfer case? |
