So weird seeing this vid 2yrs after it was made because we now just have a rtr 4ws capra and its so damn good

[@Waltkat]

I added rear steer to my Capra too. I bought an entire all metal aftermarket Capra front axle for around US$50 which came with everything including steering linkages. I wanted the rear suspension to work so I cut away part of the cage to clear the full size steering servo. In order for the servo to clear the receiver box, I 3D printed 5mm thick spacers to move the servo back enough to avoid hitting the box. Works great. I'm using a Radiolink RC6GS transmitter which has a rotary knob for channel 3 which is used for the rear steer. This knob is located near and to the rear of the normal steering wheel but it's too small to reach and operate with my left thumb while controlling the throttle at the same time. Solved this by 3D printing a new knob which is bigger and is textured for better grip. So now I can front steer with my right hand and control throttle and rear steer with my left, all at the same time. Dig is currently activated with a toggle switch but I may move it to a push button located near my left thumb. This way I can keep my hands on the controls and never take my eyes off the truck.

[@AdamJohnSwenson]

I need to trim my cage as well. Do you have a link to the file for the 5mm thick spacers? Or I suppose I could try washers too...

[@mredias3762]

Now THIS is how one should provide P/N when doing an upgrade. One that I will be performing soon.........THANKS !!!!

"Im not riding inside, so i don't care how rough it is" HaHa! That cracked me up!

[@davidmedley5970]

I'm about to buy a Capra and have been watching lots of videos. I know this video is a year old, but if you do any more bench work videos, an additional light behind the cameras would help for our viewing. Looking forward to my trip to Utah this summer.

[@Art-zs6sl]

I have been wondering about this. Thanks for posting.

[@josephwimerYoYoYo]

Thank you! I hadn't considered using a dial for rear steer. I think that is going to be a game changer for my driving.

[@sjmagrum5176]

Thank you for this video, everything I was looking for with this build.

[@doubleu2]

funny timing on this, just subbed last night and did some research on all the parts needed to do this!

[@vwagon5566]

Thank you sir for all your work and helping me fully understand this process. Always wanted to have 4WSing (I hope that's a word) on my "Goat". So thanks to you I will. 👍👍. Please post more...

[@nathanwirth9906]

Totally appreciate this video man I would have been working on this for months if I wouldn’t have watched. You showing all the parts needed was a life saver!!! I’m also very envious of the crawling landscapes you show. Thanks again!!

[@westdesertwheeler2666]

Awesome, I’m glad it helped!

[@zachgerwig7529]

Thanks man love the videos this is definitely one mob I've been wanting to do for a while now after watching this I'm ordering parts today

[@brentlykins7281]

This is exactly what I was looking for thank you

[@tiborbeetles1882]

Brilliant video, thanks from the UK 👍

[@jerryhermann7233]

I needed the radio setup.

[@garybeckwith9045]

Exactly what I needed for parts requirements. I run Radiolink and tried the pot control for 4ws on another vehicle and didn't like it. I instead shifted to mixing (slaving) the rear into a 3-position switch for rear steer on/off with the main steer. Works great. I don't know if the GT5 can do that . Looking at your crawling videos I can see why you need variable. I don't. Another example of setting the rig up for the normal terrain.

[@210419590457]

Thank you for this vidéo, it is well done and very useful. Have a good holiday. 👍👍👍👍

Good information just bought a used capra store return super cheap adding r.steer.thanks race nitro truggys need crawler info.have that radio for my x factor awesome video s on the rocks

[@kimandreblesvik3451]

Recomend using sanwa mt4 radio. Perfect radio for 4ws rigs, using the lever joystick to control the rear steer.

[@CRAZYBUILD349]

thank you , your the man, all your info is very grateful, can we buy a front axle all ready assembled????? now a year later? i have a capra 4ws but Iam making one too, and cant find the set I need,

[@trevorprewitt9394]

Very cool I've been waiting for you to do a tutorial good job with explaining my one request is the lighting would be better if it was on the other side of you 😀 I will look into buying that controller

[@vwagon5566]

Trevor that's a fantastic transmitter, feels good in hand, lite weight, 20 separate vehicles, trucks, cars and boats. Cheap for what it's capable of doing. Win-win. Imo..

[@StudQBeefpile]

Just a heads up. . .I think the knuckle screws are AX31403 instead of AX31489.

[@desertghost5668]

Great video. Do think that the new Capra 4WS RTR will be as capable as yours?

[@CrawlerCanyon]

The Spektrum family of 5-channel radios (DX5C, DX5 Rugged, DX5 Pro) all have full channel mixing for four wheel steering, including selectable mix for front only, rear only, crab, and four wheel steer. Also, many low-profile servos will clear the back of the the cage without cutting.

[@Braindog]

The FS GT5 has all Modes in it. U can change it in 4 Modes for 4 Wheel Steering in the Menu.

[@CrawlerCanyon]

@@Braindog I would say the weakness with the GT5 is the inability to assign the 4WS function to a specific button. If you wanna use it, you have to use the menu wheel, and it's really tough to steer and operate that menu scroller at the same time. I will say that setting up 4WS on the GT5 is an absolute breeze compared to the Spektrum.

[@elvicio-zd3hu]

Hi .. I love your videos .... It is also possible to buy the complete front axle and that's it, right? less manpower true

[@blink730]

Hey thanks for the videos. Love the scenery you get to crawl through.. I've been thinking about doing this.. so you think a real strong servo is needed for the rear or how strong should I go with? I'm trying to build this body more on the light side

i wish you went over how you actually control the transmitter. i have the same transmitter with rear steer on channel 6, even bought a clamp on thumb wheel and i still struggle with controlling everything

I noticed your clearance links you have what is the brand on those cause I can’t find those anywhere!?

[@Fabio13Devil]

Hello can i use 2 complete front axels to do 4ws? Or i need to use the rear axle pinion and gear?

[@mikesblueskyproductionsuta7634]

Never thought about eliminating my rear springs. 🤔 I may need to try that. I saw on one of your other vids, that you removed your spring caps on your front shocks. How has that been working?

[@davidmedley5970]

Hey Logan, loving my 4WS Capra. Just purchased a FS GT5 and swapping it out with the factory Spectrum receiver is not as straight forward as I thought. Can you help me out with this? I’ll be in St George in June and looking forward to go wheeling. Any help would be appreciated.

[@27hogue]

Hopefully you see this I know it’s an old video, I bought the 4WS capra RTR. I’m wanting to add dig so I need a new receiver. My question is sense the spectrum is a 2 and 1 system can I even use this receiver? And if so what do I need to do to get it set up? I don’t want to change the motor or anything like that yet.

[@mredias3762]

Hey West Desert Wheeler, REAT video !!!!PLEASE get back to gigiboxa and I as these two P/N (AXI31489 & AX31403 )do look the same but ARE of different dimensions.

[@mattsmith5432]

I totally mean this in a positive way, but thanks to you I bought a Bully2 MOA and now I'm thinking of a scratch build Capra with all the good stuff I see in your vids haha. I have a UTB18 already and am thinking of RWS for it as well as other upgrades before I go full-size Capra. I watched your video on the UTB18 and wanted to know if you have tried anything crazy with it yet? Thanks again for the great videos and info!

It is currently tore apart waiting for a brushless system, rear steer Reefs raw 400 and other goodies

@@westdesertwheeler2666 Same here. I am going with a Holmes Revolver and Mamba X2 to start. I used your affiliate link and have a GT5 on the way and ordered all the other goodies through my local RC Shop including the steering axle for the rear. Will probably put the stock servo in back and get a good one for up front. Can't wait to see what you do with yours.

Thanks. Will the flysky gt5 work with the receiver/esc combo unit , firma 40a, that comes stock on the capra rtr?

[@rollmeover5547]

I am thinking about building a kit capra and making it rear steer while I’m building it. Do you think it would be cheaper to buy the kit then convert it to 4ws or to just buy the 4ws rtr. Thanks

[@westdesertwheeler2666]

The 4ws is the cheaper alternative

[@rollmeover5547]

Thanks! Picked it up this morning! Love it

[@BoomslangSuss]

You didn’t have to trim any of the chassis rails to clear the rear servo?

[@westdesertwheeler2666]

It’s optional

[@ohsofilthyeazyre5771]

I got the screws but the don't fit in the knuckle I don't get it

[@Mr._Dice006]

How about the drive shaft rotation?

[@westdesertwheeler2666]

What do you mean? The axles rotate the same if you swap ends. So a front will still work fine on the rear

[@Miniscapes515]

When I got to 4ws and hit the inhibit button it won't let me scroll up

[@EthanCmsrc108]

Aren’t the Capra portals the same as the 10.3 portals?

[@westdesertwheeler2666]

The portal gears and diffs are. Axle shafts are narrower due to width

[@Guden79]

Hey :-) could it be, that AXIA1264 is totally wrong for this build? Servomount is included with front-axle :-)

[@westdesertwheeler2666]

It’s the screws not included with the servo mount 👌🏽

[@HBFTimmahh]

Hey Logan. Now that you have your Capra CMS mount available, do you think it could be modified to work in the rear for rear steer, opposed to having the servo mounted on the axle? thinking of taking my original rtr Capra and going Rear Steer with it using your mount. LMK what you think.

[@westdesertwheeler2666]

It will not work on the rear
