Just made the switch to Traxxas. Pricey, but I only have one boat right now. The Male connector has contacts on the top and plastic on the bottom, so you cannot cross-connect. Lots of contact area for high current loads. They have a nice, solid feel to them -- when you plug male into female, you know they have good contact and are not going anywhere. LOTS of surface area with raised details to make unplugging a wet connector easy.
