Re: new2rocks Guide to the TRX-4 I'm new to the RC hobby, and newer to crawling. I bought the TRX4 mainly because I know the Traxxas name won't disappoint, and this thread has been a Godsend. So much useful information in here. All I've done to mine so far (3 weeks now) is take the portal and diff covers off to lube them up, change the oil in the shocks to 15wt, and play super hard with it (at least 30 battery packs run through it) without a single problem. Love this truck, and my boys (5 and 6) love it and have been super hard on it as well. I know something will eventually break, but so far it's a lot more durable and fun than my Traxxas Slash, and I can give the controller to my kids without fear because it tops out at abou 10mph. Thanks so much for this thread...there are several others on this forum as well, but this one has helped the most. |

Welcome to RC, RCC and crawling, and thanks for the kind words! Glad to hear you're enjoying your TRX-4 so far (it's a great truck) and that you've found the guide helpful. Also glad to hear you're getting the kids involved. It's so much more fun with family involved. "thumbsup" |
Re: new2rocks Guide to the TRX-4 Lots of great info here. I've been staring at my shopping cart at RPP Hobby, ready to click buy. Any thoughts on running a 550 brushless motor, like the Team Brood Vigor 550 2000kv? Would it be overkill? |

Re: new2rocks Guide to the TRX-4 Are you going for "insanely fast" speed? Why? |

Re: new2rocks Guide to the TRX-4 Quote:
Agreed. The only reason for a 550 brushed instead of 540 brushed is to handle the tall top gear ratio. A good 4-pole 540 brushless will have plenty of torque to handle the gearing, and with a low kv (e.g. 2200) 540 can, top speed is already giddy. |
Re: new2rocks Guide to the TRX-4 I stuffed a 3500kv hobbystar pro4 in mine and I am very happy with the results on 3s. |
Re: new2rocks Guide to the TRX-4 It's time for some updates. Started with the intro to add info on the new Bronco and kit versions. More updates to come... "thumbsup" |
Re: new2rocks Guide to the TRX-4 Added new section 2 with performance upgrade recommendations and updated axle section to discuss portal delete option. "thumbsup" |
Re: new2rocks Guide to the TRX-4 In the performance section, you note on behalf of HH: "Holmes Hobbies offers the TorqueMaster Pro 550 in 21T and a limited edition 30T. They also offer the Crawlmaster Pro 550 (which is a 5-slot design) in 10T and 12T flavors, which would be comparable to a 21T and 27T 3-slot motor, respectively" Any thoughts on how much it will impact performance to go with those motors that are not reverse turn, like the stock motor? PS: why is this thread not stickyed yet? |

You can also specify what timing and direction you want when ordering directly from Homes. |
Re: new2rocks Guide to the TRX-4 New2rocks, what an awesome write up! Thanks for all the effort you put in! |
Re: new2rocks Guide to the TRX-4 Which model is that manual included? My bronco came with very little info/lack of a manual other than start up |
Re: new2rocks Guide to the TRX-4 Started putting my kit together the other night and found my trans gear to be undersized as well, if you need another data point. |
Re: new2rocks Guide to the TRX-4 First of all, what a great topic! "thumbsup" Suggestion for updating 4. Motor and ESC. Quote:
In the page MOTOR RECOMMENDATIONS you can find the recommendation from Holmes Hobbies for the TRX-4. https://holmeshobbies.com/motor-recommendations TRAXXAS TRX-4 General Trail use: 27t – 21t TrailMaster Sport 550 27t – 21t TorqueMaster 550 12t – 10t CrawlMaster 550 Puller Pro BL 540 Standard TrailMaster Pro BL 540 I personally run the Trailmaster Sport 550 27T with the stock TRX-4 ESC in both my TRX-4s and it is smooth, powerfull and not expensive. Also got a question. You suggest to get 80mm shocks or to mod the standard ones. Quote:

Re: new2rocks Guide to the TRX-4 So, does the Team Raffee body fit on the stock TRX-4 Defender Chassis? |
Re: new2rocks Guide to the TRX-4 Will swapping to slightly softer spring rates f/r effectively give you a lowered ride height without switching to a shorter length shock, which I assume would limit the suspension travel range? |
