Receiver dust cover
 

Has anyone ever come up with a decent way to keep dirt and dust out of their receiver when mounted in an off road car or truck that doesn't have a receiver box?

I am looking to shed as much weight as possible in my Losi SCTE and using a spektrum 3500 micro and getting rid of the receiver box and mounting it directly to the car but I want to figure out some way to keep dust and dirt out. Since the receiver will be mounted with servo tape, I will need something that just fits over the top and is lightweight.

Any suggestions? Anyone make such a thing already?
