BRCA rules - reverse & bodyshell painting

[Yorkiebar]

Hi all,

I'm trying to find a definitive answer on this old coconut - the use of reverse when racing.

I've read through the entire rule set for 1/10th offroad and I can find no mention of reverse being banned for racing use, so did this just come about as a local level gentlemen's agreement? Or was it a ruling in the past?

The other rule I'd like to find some confirmation on is painting of a shell. I had an idea for a design which meant the windows were painted over, but was told that it was a ruling the windows had to be clear? Again, I can't find anything on this, and some out of the box designs like a Tamiya Dark Impact have opaque window coverings from memory.

Anyone in the know able to clarify please?
