Default Tonka TRX4 Tow Truck

I have a project I am working on where the chassis and WB have to match the body, and I am using the TRX4. Once I get it done I will post up a proper build thread, but given all of the work still to be done, it will be a while.

For this project I needed the WB to be just 9 1/8", that made me get creative. the back end wasn't that big of a challenge, it is just a shortened 4-link, but the front end with the pan-hard bar challenged me a bit.

Also, the suspension is really short. I am running droop in the front with a compressed eye-to-eye length of 80mm. The back is even shorter and I am still looking for shocks, I am thinking of maybe 4-Tec. For now I just put solid links where the shocks would go, but I am amazed how much articulation I am getting.

Looking at running droop in the back, anyone know of a shock that is 40mm (ish) eye-to-eye when fully compressed?

I have some cco1 70mm shocks which I believe are 40mm fully compressed..... I will check on that in a bit.

Progress continues on this project. I am starting to get the parts and pieces put together, but it is a little disheartening to know that it all has to come apart before it can all go back together again.

But, I do have one major shareable milestone in the bag...

When I saw these rear portal mounts with shock mounting provisions, I thought they could help on builds like this.



I believe they could be installed in the opposite direction so the shocks mount on the back of the axle which would move the upper mount higher on the chassis like this:



With raising the upper mount and lowering the bottom mount, you would be looking for a shock closer to 60 mm compressed (about a 80 mm uncompressed) which would be much easier to find.

More work on McShorty... Other than a few odds and ends, the chassis is almost ready. The body is almost ready as well, almost time to strip and repaint. One thing really left to do, and it is really giving me fits to get it right, but that is half the fun of this project.

Here are a couple of pics...

This one shows the difference in WB from my 12.3" TRX4 and McShorty.

The drive shafts took a little bit to get right as well...

Just need to install the kit to get it out of mode 2 and we'll be in business.

As far as the truck itself goes, just waiting for Spring, literally... It is too cold in my garage for stripping and painting right now. Can't wait until it warms up, 10*/f almost feels like shorts and tanktop weather...

Sorry I have not kept up with this thread, if you are interested, there is a more detailed build thread over on the Traxxas forums (linked below).

Here is a quick video update, will add more pics and a running video in the next couple of days.

Many thanks!

Here is some running video of this guy. Like I said in the previous video, the booms still need some tweaking. I am thinking about getting rid of them altogether and just going with a big winch in the back.

And, some pictures with it lit up...
