ALUMINUM SLIPPER DISK

Nitro vehicles use aluminum clutch shoes inside hardened steel clutch bells so there's the hardened steel slipper disk already on the ERBE, why not use an aluminum slipper pad. So that's the route I decided to take. I have been extensively testing this slipper for the past month and it is holding up to just about any kind of abuse I give it. I tried a carbon fiber slipper disk before that and it held up for a while but failed once it got the abuse of racing at the track.

This is how the disk looks after more than 25 cycles of 4, 5 and 6S runs at the track and bashing. The middle disk is the test one, the left one is new and to the right is the slipper steel plate.

Here are the measurements to make one out of a piece of aluminum anywhere between 2 and 3 mm thick. I tried to be as accurate as I could with the measurements.

BULKHEADS

I have a tendency to over tighten screws sometimes. Especially with the plastic bulkheads. I feel these need to be sitting as tight as possible against the chassis but I often stripped the threads in the plastic trying to do so. I installed some Dubro brass inserts to deal with this problem. Now I can torque those screws very tight and I believe that this helps make the bulkheads sit very snuggly against the chassis adding to the overall structural strength.
I used the 4-40 inserts for the screws that go through the shock towers and 6-32 inserts for the rest on the screws.

ROCKER POSTS

I don't know about you but when I want to take the rockers arms and this happens, it annoys me.

The P2 progressive rockers will be used but this is a small modification I like to do to the rocker posts. I take out the M4 button head screw, I make sure the rocker post is firmly screwed to the bulkhead. Then I take an M4X.7X16 mm set screw and screw it firmly in the rocker post with red Locktite. I then use an M4 Nylok nut to secure the rockers. Whenever I need to take a rocker out, the post stays in the bulkhead.

REAR BODY POST

There’s not much to say about the rear body post but I just wanted to show what I did to it. The body post used on the ERBE is the same as the 3.3 Revo with Easy Start so it has this orifice in it for the Easy Start plug. It is not used for the ERBE so I sanded it off with a sanding drum.

AXLE CARRIERS

This is something I always do with the axle carriers. I use a longer screw and a lock nut.
