Default Scale 4x4 R/C builds a SCX10 6x6

So I had an extra SCX10 kit courtesy of Axial show up one day and I decided to start back down the road of a multi-axled rig. My last one was a lot of fun to build and an interesting challenge. So I decided that I would see what it took to build one out of two SCX10's. I know it had been done but I wanted to see how easy/difficult it was to do. So with that in mind I googled 6x6 SCX10 and found numerous results.

After looking a few of the links and watching a video or two I realized that while there was plenty of info and it seemed pretty straight forward I was still somewhat unclear of how everything went together and what parts were needed. So I decided to see if I could come up with a method that used only the parts that came within the two kits and didn't require any special parts to be created or purchased. So with that said, I am going show what I did to make mine work!


First the parts that you'll need:
  • AX30502 - Chassis rails
  • AX80003 - Solid axle set - you'll need the two output/input shaft sides for the center axle: RCSparks has a good how to on this, so no need to rehash.
  • AX30518 - 6x98mm link
  • AX80005-2 - angled neck ballend (installs on 98mm link)
  • ZX30516 - 6x106mm link
  • AX80005-1 - straight neck ballend (installed on 106mm link)
  • AX80005-6 - angled neck ballend (installed on 106mm link)
  • AX80026B-2 - x style cross brace
  • AX80126-8 - rear bumper cross brace
  • AX80043-1 - center link mount for axle - you will need this for both center and rear axle.
  • AX80003-1 - this is a center mount for the top of what is normally the front axle, I use this on the bottom of the rear axle (trimmed) for the screws to tighten into.
  • AX80025-3 - rear shock hoops
With this parts list, you'll have everything you need to create the 6x6. If you have two complete SCX10's and the spare parts that came with them then you shouldn't have a need to buy anything else. This is not every part you'll use obviously, as I didn't mention the drive shaft, axle internals, etc. But you'll have those anyway and will be able to figure out how to use them. This is more about getting the axles installed.

Here are my completed links


Here is the center axle link set up, as you can see this is pretty much stock




Here is a look at the rear axle upper link mount

In the image below you can see how the two "angled neck ballends" differ and are used.


Here is how the links mount to the center axle (these are the links between the center and rear axle)


Here you can see how the links mount to the rear axle, lower links and shock mount in the same location on the axle.



Rear axle center link mount.


Here is a good view of how the links look from underneath.


This shows the top link mount that I trimmed to use on the bottom of the rear axle.


Here is a view of the chassis extension. I cut the chassis just before the bend. This will be clear in the video that I will post later.




I'll be post a video later that sort of walks through some of this. But if you have any questions please let me know as I am more than happy to try and answer.

I think it's time for an update on the 6x6 build.

1st, I've made modification to the chassis to deal with the flex issue I was having, I'll be posting that in a few days.

In the mean time Mike and Rick are debating about which tire combo should go on the newly received Rogue Element Components wheels.


Mike wants the bigger tire option while Rick seems to prefer the smaller option.






I personally prefer the middle option which is a Proline Flat Iron (front).

Here is the update on 6x6.






As you can see in the images above, I changed how the two chassis sections connected together. While it doesn't completely eliminate all chassis flex it significantly reduces it. You can see the old way below for comparison.

I did similar in 2011 but made the rear axle steer too, it ended up with the same turning circle as the standard SCX10
