Here's a couple pics to update the ongoing changes. The first is my home made foam filter. Just a hollowed out foam, and left a lip to go around the motor can, held with a zip tie. I cut slots and some holes for the motor wires. it gets oiled and cleaned to keep crap out.
I also lined the battery tray with velcro. It's more for shock protection of the batteries than anything
A little velcro helps keep the side impact from hitting the carbon center dif mount and helps stability
Then I put velcro on the batteries and also on the back of the esc and battery plugs. After the battery gets plug in, it gets tacked on to the side of the battery. It keeps things from moving around and that should also stop me from getting the battery unplugged again.
I didn't get any pics of the steering ackerman I made. I took a bike tool and cut it wih the big carbide discs I have, then heat treated it to harden it. I had to go buy a new titanium nitride drill bit just to get through it hehe. I polished it after with the dremmel a bit.
