e378 - 2WD/4WD Selectable Traxxas TRX4 - Shodog TRX4 Part 5

[@liamchilver1691]

This is a feature I've always said I wish was more common on rc crawlers

[@AMPROEngineering]

Same here. Weirdly, this is what the Tamiya Hilux and Bruiser had at the start. Then it just vanished.

[@liamchilver1691]

@@AMPROEngineering hopefully one day it'll become a more common feature. Also unrelated, I'm looking forward to hearing what your thoughts are on the new tamiya bbx. Seems like the right kind of modern buggy for you

[@FreedomYak]

So satisfying to watch it switch on the fly and recover itself. That is a nice bit of engineering.

[@AMPROEngineering]

Seriously it is. I have so much more fun with this now.

[@chibiskyrc]

I finally picked up a TRX4 Defender for a steal used yesterday and I've literally been thinking about this! This is awesome! It would be cool to see even the remote locking diffs implemented on the Tamiya trail trucks seeing how they have diffs from the factory or even implementing a 4WD system similar to a bruiser on a more capable platform

[@AMPROEngineering]

I have wanted to do that also. For a while i was contemplating installing these axles since they are better.

[@willanderson5088]

Idk why KZbin has taken so long to show me your channel with the years of rc researching I’ve done but so glad I found it. Awesome video

[@AMPROEngineering]

Lately KZbin hasnt shown me any channels under 250k subs. Money I think. Glad you found it too!

[@yfzermatteee]

You can reverse servo operation in the transmitter menu. Look up the option tree.

[@AMPROEngineering]

Yes but that wont work for how I made the axle lockers work.

[@michaelmccameron5959]

Dude are we ever gonnna be able to pick this up.whats goin on

[@AMPROEngineering]

They have been selling them a while now. Are you on the discord group?

[@millboss1372]

I never thought of how fun the trx4 would be in 2wd. Great idea/kit.

[@AMPROEngineering]

It is a lot more engaging as you drive.

[@JosephBuffkin]

@@AMPROEngineering how do in get the kit

[@timothybrown1189]

I'm on the waiting list and can't wait to get this. Thank you for the lead. I do think I'll be figuring out a way to run the rear locker independently. I think it would be fun to spin doughnuts in 2wd locked. Only because not many crawlers can "hoon" and crawl. Or maybe just spool the rear end and use the rear locker servo for 4wd shifting for a cleaner install.

[@AMPROEngineering]

I know they are slowing making them! It is a better idea to run a more capable radio but I didnt want people to think it was needed.

[@jesseharriott4253]

I swapped diff lock servos channels on the receiver and then used the menu and set button to reverse their direction so rear locks first then the front. It makes more sense to me because I like drifting

[@AMPROEngineering]

Oh nice. That works.

[@TheAmericanUhate]

I asked to be put on the waiting list to buy a kit, can't wait!

[@AMPROEngineering]

They just showed me the final version!

[@All_RC_Fun]

That is a very cool upgrade. Great demonstration. Your trail buddy was eager to assist. 😊

[@AMPROEngineering]

I know I love it. Oh yeah, he’s very helpful!

[@dcrafty427]

So excited for this kit! Already signed up on the website!

[@AMPROEngineering]

Nice! I ordered a second.

[@madonion48]

Amazing. I booked my reservation too ! It would be great to be able to also lock the rear diff when in RWD.

[@AMPROEngineering]

Awesome. This is a killer truck with that 2wd/4wd shifter.

[@timothybrown1189]

Just got mine today! Thanks for the lead. Can't wait to install it. I'm going to upgrade theradio. I wanted to keep the stock but I also want full control of the lockers and 2wd. You can still get on the list, I signed up for another kit. You can order multiple but I didn't want to make anyone have to wait any longer for theirs.

[@AMPROEngineering]

AWESOME! Glad these are shipping! So nice to see people making amazing stuff for the hobby. I love this option.

[@bshizle8410]

How much does this kit cost? Their website doesn't show bc they're on a waiting list

[@xargon1234]

First of the kits have gone out a couple days ago some have received them already, looks like they only have 4 teeth instead of 6 in the final will ship with 3d printed parts and are $150

[@AMPROEngineering]

Awesome. I already got my new one.

[@The_RC_Guru]

I will be looking forward to the website selling these kits! I don’t have a discord acct. Best one of these 2wd 4wd mods yet.

[@AMPROEngineering]

Yeah I rarely go to discord but I signed up and am on the list for the production one! Can't wait.

[@evanwebber9981]

I'm building a 2 door JK out of my TRX4 right now, I would love to add this eventually! I want to try and configure it so I would have 2hi/4hi/4lo like a real JK would. I think I could make it work, since I changed over to a Radiolink RC6GS radio. Awesome kit!

[@AMPROEngineering]

That would be cool. I had limitations since I didn't want to change the radio.

[@evanwebber9981]

@@AMPROEngineering What kind of tolerance is there between the gear and the shift dog? Is there much slack?

[@thqp]

That is a really satisfying setup! Love watching it go!

[@AMPROEngineering]

Me too. It makes this truck so much more fun!

[@IowaBudgetRCBashers]

This thing is so cool!! The pinto mags really make this look legit

[@AMPROEngineering]

Thanks! I have those wheels on one of my pintos so this truck needed them!

[@IowaBudgetRCBashers]

This mod is absolutely genius.

[@AMPROEngineering]

I am in love with it.

[@viru52000]

Cool addition, might help with turning radius as well.

[@CptnKapti]

Especially if you lock the rear diff and gas it!

[@AMPROEngineering]

HAHA! Oh thats the truth!

[@mikeymike3240]

The kids are really precious, aren’t they, yah just gotta love em 😊, that’s a great bit of kit to fit, it’s amazing 🤩

[@AMPROEngineering]

Crap was something in there? Haha! I thought it was just a hole!

[@jonnyroberts225]

@@AMPROEngineering I tried pausing the video, thought I could see an owls head. If it was, probably a young one hiding until feeding time from it's mum 😃

[@l0ls13]

wonder how far along is the company on releasing this kit. I check their site regularly seems like there isn't much progress.

[@AMPROEngineering]

They are trying to ramp up production. They do this on the side and demand has been high so it is not easy to keep up with demand. Even I want another one!

[@TheAmericanUhate]

I keep checking every few months. Hopefully this is still going to happen

[@AMPROEngineering]

They are already filling orders. I think it's just slow based on the fact they do it in house.

[@TheAmericanUhate]

@@AMPROEngineering How do I order one? On their site, it only tells me to be put on a list to be notified for them.

[@Sol-hl2rj]

Wow! This is a really nice option, very interesting! A 5th and maybe 6th channel would be the icing though.. You would maybe achieve the same servo reverse via Traxxas’ app. You’ll need to purchase the bluetooth module for the TQi - there you can servo reverse all channels within the app. I run my TRX-4 with servo reverse on the diff lockers - this enables the rear diff to lock first, then the front. Another option is to add one more hardware switch to have totally independent diff lock options. (The link didn’t work on iOS by the way..)

[@Chrisflyss]

I decided to go with a 6ch radio. I'm using Radiolink and it's been absolutely awesome. Completely independent lockers, low/high gear and 2wd/4wd.

[@AMPROEngineering]

Yeah, a better radio is totally the way. The guys that made this showed me how they were using it but I felt that some would not want an additional cost. There were limitations for the stock radio but for the cost, it works!

[@AMPROEngineering]

Yeah that is the one to get.

[@Sol-hl2rj]

I see what you mean about holding the cost down. And, the TQI is a good radio. Many will want to keep it for Pro Scale Lighting, as me. I opened one of mine: A video about adding a single action flip switch might be a good idea. From my memory it’s a three position switch with common ground. Left is off, first action activates one wire, second action the next wire. I’d believe that making a jump ground between the old and a second switch and just moving the second red positive wire to the new switch would work. Then you’d have independent diff lock/unlock.

[@selenaenochs8540]

This thing looks amazing man absolutely beautiful

[@AMPROEngineering]

well thank you! It was an awesome build!

[@chadzigler]

i am gonna buy another trx4, this be easier to work on with the right parts compared to mix match parts lol. waitin list i am on, will check discord out if the link is still active

[@AMPROEngineering]

It sure it. They are slowing building sets. They have an updated version people are getting which is cool!

[@mwesston]

Super neat upgrade! Finally a selectable 2wd trans in something other than a Bruiser. I wonder how this would perform in the Heavy Hauler?

[@AMPROEngineering]

It is a well made metal part so I cant imagine that it wont work well.

[@helmydewa]

Wow this is exactly what I'm looking for, so it can drive on asphalt or another high traction surface without transmission binding, where i can get one...? I'm from Indonesia, I'm really interested in this...

[@pallito020390]

@@AMPROEngineering any updates?

[@DoRC]

I wonder if you could just flip the servo horn to the other side of one of the locker servos to reverse its direction.

[@AMPROEngineering]

So I did that but reversing the horn and the servo means it does the same thing.

[@DoRC]

@@AMPROEngineering can you not just put the horn on the other side of the servo?

Hopefully this will soon be aviable :-)
