Have been desperately looking for something to help keep the Turbo Shotgun Epoch's wheels on the ground instead flipping right off the track just because you didn’t accelerate into the turn perfectly on the traction side of an RCP track without the obvious but totally unacceptable answer of slowing down.

This did not help the rolling but it did help tracking.

Remove the front suspension access cover.
Fill the king pin holes with epoxy.
Let epoxy dry and harden completely (preferably over night).
Drill new holes ½ of the king pin diameter closer to the outer edge with a #54 bit.

By moving the bottom of the king pins out you also get a slight toe-in, if you were to do it to the top holes you would get a toe-out.

I would not recommend this if you only have one Epoch but if you have several you can then easily swap the plates out between cars.

Seems like a place for you to do some mill work :) How easy or difficult would it be to mill out a new top plate?

With the right mill, it would be pretty easy. I need to finish the work on mine to do it without a major effort. If I can get around to finishing the belt drive and CNC upgrade it shouldn’t be too difficult though.

Making one would solve part of the rolling problem I’ve found too. The problem is that at the speed the SE is capable of when you corner with out a top spring spacer it depresses the spring far enough to catch the part that holds the king pin on the rough RCP surface. But that extra spacer also limits the suspension travel since for racing it needs the spacer below the knuckle to keep it from rolling due to a the higher center of gravity. When making one you could build in the spacer using that higher part to hold the king pin eliminating the section that extends below the chassis altogether. It looks like you could use a flat piece of CF eliminating anything that protrudes below the chassis altogether, which would also be a piece quite a bit easier to mill too. Hmm, might have to try a level CF plate.

So is the pro-epoch chassis done yet? :) I can seriously see you finishing the pancar chassis everyone has brought up once in a while.

EDIT:

found a decent servo to gut for use in a pancar mod (this would remove the stock gearbox for a cleaner servo based install): http://www.allerc.com/product_info.php?cPath=40&products_id=1195&osCsid=9f92574904ddc5a284dc782b5ccef4ae
