New grade 5 titanium plates on GorillaMaxx G2R

The reason for this custom build was that my GorillaMaxx G2R was the carbon edition with the 0.09" thick carbon fiber top plates. I always thought they were too thin and they did end up breaking.

I considered many options and eventually decided to make new plates in .090" grade 5 titanium instead. I looked on ebay and finally found a scrap piece. I then drew the plates in Google Sketchup, converted them to .dxf and had a friend cut them using a wire cutter and a final bead blasting.

You are welcome to re-use my drawings for your own projects: Download .dxf drawings (single .zip file)

Here are some pictures of the G2R before and after:

Custom RC-Monster center diff/motor mount mounting plate

I was in need of a RC-Monster universal center diff/motor mount mounting plate for my GorillaMaxx G2 chassis so I went ahead and made this together with a friend (Thanks, Henrik!).

You can see more pictures of it installed in the gallery for truck #6.

Edit: A number of these mounting plates were sold on the UE forum.

Wing mount for use with Mugen MBX6T wing mount and UE KnuckleHead tower

I wanted to install a wing on my UE KnuckleHead tower and came up with this wing mount together with my friend Henrik.

It is designed for use with the Mugen MBX6TR wing mount (E0411, MUGE0087).

Edit: A number of these wing mounts were sold on the UE forum.

8 Spider differential (a.k.a. Unlimited Engineering 8 spider diff)

This build is inspired by this guide (thanks to Neil (a.k.a. ArmyofDarkness, a.k.a. suicideneil) for always helping out):

http://traxxas.com/forums/showthread.php?8926045-Unlimited-Engineering-option-for-Upgraded-diffs-in-the-Emaxx-(-all-models-)

- On ebay I found some nice looking, used 8 spider diffs:



- Remove the six screws using a size 2 hex. Carefully take the diff apart:



- Pull off the side gears, slide out the pins and pull out the drive cups:





- I use the Traxxas stub axles (#5454) which I modify to length using a hacksaw and a fine metal file. This allows me to use the Traxxas steel CVD's (#5451R):



- Insert the modified #5454 shaft and assemble the side gears again:





- Remember to put the sealing rings on both sides of the diff case:



- Observe the very nice looking spider gears. Make sure they are all in good condition and that they all have the small shim installed:



- Install the spider gears in the diff cup (can be a bit tricky) and fill it up with diff oil of your choosing (I used 10000 for a front diff in this case):



- Tighten the 6 screws holding the diff together lightly and you are done:



Note: Neil mentions parts/alternatives needed to complete the installation of the diffs.

- As an alternative to the Traxxas #5454 you can get the RC-Monster 1/8 diff output shaft:



- If you plan on using the stock plastic center drive shafts you need to use the RC-Monster Revo drive shaft coupler (8mm bore):



- If you plan on using the Traxxas steel center CVD's (#5151R) you will need to use a drive cup with 8mm bore like the RC-Monster hardened steel drive cup:
