MGM Compro 160...Hydro Version???
 

If my MM setup doesn't work out I was looking at the MGM Compro 160 with the switching BEC. I just don't get what "Hydro Version" means?

Can someone explain this.

Hydro version means it is at least splashproof, with a thin clear protective layer around the circuitry. This is good because it's easy to accidentally get harmful water or other debris onto ESCs in our cars/trucks.
