these things are so reliable its mad, get rid of the traxxas electronics and went power hd micro servos, savox steering and hw axe motor and zero problems. broke the pin that connects the front portal to the shaft the other day after nearly weekly use from release, i measuered the other pin and it had worn down to 0.8mm where it contacts the gear. replaced pins and still going strong

[@jamesplymire5342]

I just seen it in the comments but I was gonna mention the Ecopower Micro Servos. They are a great little servo.

I replaced one of mini servo with a EcoPower 640T for the 2 speed transmission. Great little unit!

Excellent advice for a TRX4. I followed most all your tips and my rigs are perfect for what I expect out of them. Stock motor lasted me three years with weekly river crossings.

[@markcole6475]

I’ve been upgrading my recent TRX4 Brown F150 high trail! Brass C knuckles , brass hubs , light kit , HW fusion pro 2300 kv , upgraded wheels and tires ( a little smaller ..imo the stock tires are too big) I love watching your upgrades and throughly impressed with your knowledge of the RC world.

Tha k you for this return that could help a lot new TRX owners. For my opinion, this truck is very well born and extremely reliable in any use, that so rare to mark it bolded. He will be so much better with a lot of weight as low as possible No needed of anything over the wheel level, but axles,links,portal hub, wheel hex, ... In brass and it run so much realistically New shocks mount of longer shocks to 100mm could be good, not so hard to keep all whells on ground as often as possible And alloy beadlock wheels and tires 1.9' dependant on ground you want, stock tires are good for begin and sand surface But as soon as you drive on softer or rock or water, tires are made to excellence for these uses. Add a controller one hand wheel steering to be at top of confort. With cruise control you are so easy to fun. All other mods are not necessary but I prefer add lights, ESS dual sound, all metal accessories for looking, light don't forget, and tqi Bluetooth. Stock motor survives at all I try to kill him, including salt water and beach, just redo brushes. You could change but brushed motor are hard to kill. If rock crawling, it should be stay for years. That's it. My opinion From France 🇲🇫 Cheers

[@dirtysteve4878]

@ RC Girl It looks like your passenger side tires are on backwards, but maybe I'm wrong.

PowerHD for micro servos. Replaced my stock and haven’t had any problems yet. 1 year strong.

[@mauriceprudhomme5296]

I agree with everything you said. Stock shocks can’t be beat.

[@jamesmorrell2901]

I agree: I have them on two other non-Traxxas vehicles.

[@SandJ-Adventures]

A really interesting video! We bought our TRX4 Defenders a year ago now and have used your thoughts and ideas when considering what i wanted to change or up-grade. We didn't go full metal axles, but much of your other ideas have been taken on board! So its great to hear that after 3 years your TRX4 is still going well on what you chose. We are well happy with ours - long may they, and your videos about them continue!

[@andreaskey5371]

I just changed the 3 mini servos recently

[@ruddygomez1455]

How do I get the links for the parts cause I have a defender and I wanna upgrade it to have more weight on the bottom

[@gonzaloguerrero3110]

I enjoyed your video it was really helpful thank you 😊

[@rastaralph7154]

Hello. I was offered one of them last night for cheap. It's only 1 year old and he's only used it 3 times and paid about £900 for loads of extras and only wants about £380 for it but I've got a cen genesis that he's wanted for years. It's barely run in. I bought it new and when I was running it in the pullstart snapped and I've still not fixed it about 15 years later. I have one but I never have time to do stuff like that. You can get carried away upgrading, I know I bought a t maxx and another in bits but the other is all custom parts made from aluminium instead of plastic Which looks mint but it's in bit's. I did build it once and found it's a drive shaft from complete so took it to bits again to upgrade the other because it's got an aftermarket racing engine and hand made tuned pipe on it and does about 90 mph. It's actually hard to keep it on 4 wheels on any terrain. Do you think I should buy or swap the genesis for the TRX? I really do like them and it will be nice to just switch on and go instead of getting the engine going even though that's half the fun and better sounding. Subbed for more cool videos. Do you have many r/c's? ❤️💛💚👍

[@frenchie177]

I've got a wonderful TRX4 and started upgrading and making the chassis stronger. I put the metal gear set into the shift servo, and surprisingly I do believe I have the stock steering servo. For a 4 year old Defender its held up really well. However I've gone through countless motors. I would like to upgrade to the Hobbywing

[@ClevelandRips]

I just ordered my first TRX-4 Defender! Can’t wait to crawl it. Can I get some of your stickers to put on it??

[@gsheist]

A really helpful summary! I love that you pointed out what’s a good value for the money in terms of improving performance. Your rig looks amazing!!

[@jensa281]

I use the Power HD TR-4 micro servos in my TRX-4 Defender and they work great! Direct replacement, metal gearing and you can run 'em on 7.4V!

[@gangsterHOTLINE]

And they are high voltage too! This is great can finally up my BEC thats all that was holding me back

[@warwickeioncampbell4737]

Spend where needed and save up for the fancy longer lasting parts. I dont have one but it would be metal axles, servos (steering then micro servos) motor bead lock rims (opens up options) then accessories, added weight.

[@chrisslky7018]

Thanks for the ideas. I got a TRX4 Sport for my nephew. He doesn't use it much yet but need to keep in mind upgrades for the future. Cheers!

Absolutely great video! I just started shortly with my daughter, she want one for her 10th birthday and I got her a TRX-4M. Now I learn the in-and-outs, so that we can develop our small one over time :). I think I watched ~50 RC Videos already, in the last couple of weeks, and I like your Channel and the "RC Review" most.

[@BigWillieFPV]

Great video, agree with the brass you don’t need all of it for sure, Your Traxxas transmitter will bind up to 30 different traxxas models, get the Bluetooth module you can adjust all the settings change the multifunction knob to all different things like TSM, steering sensitivity etc, and with the Traxxas lighting kit I can change the lights high low and turn on off the head lights rock lights and roll bar lights,

[@johnmolands2326]

Completly agree with you, mine is upgraded almost like yours exept the metal axles 😉

Tr4 HD shift servos are the only option worth looking at. However I have mine on 8.5 volts and my stock servos have been fine.

[@jjshobbypower9091]

Very good video! 😊👍🏼It is important to show others what they could potential do to upgrade their rigs with all the option parts out there. I have spent over £2,000 to upgrade my TRX-4 Defender in grey and it is weighing over 5kg. I think I might have overspent on the upgrades, as you suggested not everything is necessary and might have an adverse effect. I'm sure for those who have seen my channel would think I have spent way too much on my TRX-4, but we are all in this RC hobby and free to do whatever we want, which is the beauty of it. Your Defender looks great by the way, and I watching your channel has given me some ideas of what to do to my rig. I upgraded my motor to HobbyWing Fusion 2in1 1800kV after watching your video some months ago, and I love it since I had it fitted, so big thank you to you also! Keep these lovely videos coming!! 😃😎💪🏼👍🏼

@@RCGirl haha.. I know what you mean. To some people they just don't appreciate RCs like us. It is a very nice hobby and people are genuinely very nice and helping each others. Can't believe your TRX-4 is already 3 years old, I think I got mine around the same time, we both started with the grey body but you have changed yours. 😅 oh, I have noticed you have spent some time lately on RC planes which is really cool, I'm also considering flying drone on my channel soon. I live in UK and couple of months ago I have got my licence on A2CofC and Master Class, so want to put my learning into practice. Hopefully I will have some drone footages soon, will see if I can record the rigs from drone, should be fun and cool to do. 👍🏼😅😃🥰

[@runnerbaba]

yes, but not the stock reciever....

[@mnmvuk]

Yes, the TR4 is a perfect replacement for the stock shift/diff servos. Out of two rigs, I've only lost one stock servo and the was actually my fault by trying to remove the servo arm while the radio was on. That said, I have several TR4s on the shelf ready to go when needed.

12:43 If I'm not totally mistaken the external port on the XL-5 (TRX-4 ESC) is just a connection to your battery. So solder your own plug onto the connector that you connect to your battery. Edit: Before you plug anything to the battery, make sure that it can handle the voltage the battery delivers.

[@markyates1270]

The small red connector from the TRX ESC is for accessories such as the LED lights power module etc....

If you are looking to upgrade the tires look at the pro line krawlers and proline super swampers. Jconcepts land mines are Also another great tire. Another thing worth adding is the traxxas light kits are well worth the money. They aren't quite as bright as the my trick rc but everything is well thought out and made specifically for your specific truck. I've got a few of the traxxas light kits and light bars and ive never had an issue with any of the lights burning out or the wires.
