There was a disclaimer about the rack being prototype. I'm sure its a ploy to sell as an upgrade. Typical.

get a piece of carbon fiber, trace your plastic pieces on it , use a jig saw to cut it and a dremel to round edges

I am sure Avid will jump in and make some aftermarket parts...after all they seem very focused in the 1/10 market now!

I took advantage of the channels the best I could, one with the speed control, the other with the receiver antenna. I'm really not sure if this might cause signal loss, but I ground tested it a 1/4 mile away with no issues. There is a ton of space for battery adjustment and weights if needed. Still messing with the wiring and have to install the motor.

Sorry its upside down

I cracked the seal last night. I got one thing done... put the vinyl on the chassis and cut out all the holes.

This is done with a fully built car, in ready-to-run trim, with no oil in the shocks. There is quite a bit to it actually, and id be happy to explain more if you want, just send me a PM
Now this I find funny. You were an early critic of my balance tuning method going so far as to ask why I thought my method was possibly better than using the setups that the pros developed and here you are using it after all.

If anyone wants to know how to do it, look at the "Tuning with Camber Links" thread. It's not some top secret tuning method.
