Crown gears are 10.8mm with 20 teeth. They have a 2mm bore and I have to drill them out to 2.38mm for 132 cars. For 143 I use 2mm axles so no mod is necessary

Gorrilla CA adhesive is my preferred CA. It has been formulated with a good sheer strength and can handle wrecks well. I have yet to have a chassis fail except for a wreck that propelled the car over the catch fence and down 40 inches onto a concrete floor. It was back in action in minutes.
I have one chassis running in the Pan American Proxy. It is a mid packer, running a Jack Rabbit motor and is still going with a couple of races yet to go.
I have another one running in the Trans Am proxy, but it is way underpowered running the small Mineabea S can motor, so is sitting in last place I think. No fault of the chassis though, just needs more grunt. This is why I started playing around twining up the motors. Two of them together are just short of a 100g/cm torque, but they only turn 15-16 K at 12 volts. If they get stuck on a track at 10 volts they are really slow. At home I run them at 14 volts, and at 14 volts they perform well, but I have discovered most proxies are run at 12 volts or less, so these little S cans don't do so well. They need 14 volts to come alive.
