Thanks Trevor. Do you mean a whole new thread about building cars in general? or the RB6 specifically? Id love to have post #1 on this thread.. I would be happy to spend time to fine tune/polish that first post with all information gathered up about the car... But alas, the powers that be wont give the power to be

Let me see what I can do.

It seems that every 30 posts the same questions come up. The TLR 22 thread had a sticky and it was quite helpful for me.....

Brandon, send me a request in a pm and I will look into it. If anyone is qualified to do it you are!

Busted my servo horn on Saturday. Does anyone know if the horn from the rb5 is usable? Or is there an aluminum horn that is similar to stock? Everyone is sold out of the servo set and I hate not being able to drive my rb6

Yeah it would be nice. The first page of the 22 page was very helpful. I would include a baseline setup for indoors and outdoors. Anyways Brandon where are you at as far as setup for indoors.

had my RM car working extremely well this last weekend, but had much less time then I wanted to play with setup. Got to the track late, had to re-wire the misses' car, and it was a series points race, so I decided to play it safe with setup. And I have been out of town on vacation for the last two weeks!

So like I always say... still a work in progress
