| Re: new2rocks Guide to the TRX-4
Just found this thread - great info on the TRX4 chassis and drivetrain. Can you comment on motor choice for TRX4 Sport? Does it have the same reduction as the Defender and others? I had two motors on hand, a Crawlmaster Expert 16T and a Trailmaster 550 21T (it might be a 27T - I always forget to account for the bigger can). Stock gearing currently, but I probly have some other pinions hanging around. I ended up installing the Crawlmaster and it runs real nice on 2s, a little fast on 3s, but have not tried the latter in the rocks. Did I miss the boat using the bigger but cheaper motor? Sure easy to change out. |

| Re: new2rocks Guide to the TRX-4 I'm not sure what you mean by exposed portal bearing, but I've never had any fall out. Are you sure you have the correct size bearing installed there?

The Traxxas sub-micro servos have plastic gears and can be a bit delicate. Blue Bird and EcoPower have metal gear sub-micro servos that bolt in and are much stronger. That said, I havent lost a shift/diff lock servo yet on my 2 primary TRX-4s. Last edited by new2rocks; 04-09-2020 at 06:29 PM. | ||

What type of grease is needed please. 2. Check the diff, tranny and transfer case gears for grease. Greasing from the factory in early production models has been hit or miss, which isn't uncommon with RTRs. Cases shouldn't be packed with grease, but there should be enough grease to give the gears a nice, full coating. Thank you, Uncle Pete |

Grease just the gears and not the T-lock that engages and disengages the lockers.

Adding this link as we have had wheel mounting issues cropping up a lot recently: TRX4 wheel fitment info IMHO, the link itself is worthy of being stickied, but whatever... |

I have a 2021 Bronco, I find it lacking in performance. I have been doing what I can to make it work better. Has anyone been spending any time working with the "new" bronco. I know alot can transfer over but there is some differences that can be looked at.

| Re: new2rocks Guide to the TRX-4 love this guide, I'm going to have to reverse my hubs now to see if it improves the side hilling of my TRX4 Defender, I used the bushing instead of a washer, that Tamiya stick in their 14th scale trucks instead of ball races
