For now we'll just have to do it for bragging rights.
Before we even consider a sponsor we have to popularize it.

We could do it by segment & class

Classes:
Electric
Nitro


Segments could be:
Tight technical
Longest/Fastest Sweeper
Some kind of Challenge such as:
Who can drift with a half cup of water taped to their shell without spilling

ect...

There could be more... Just the top of my head
