Hi everyone, I have an Erevo brushed with dual titans that I want to make brushless on 4s although I am looking to still keep it waterproof. I don't know a lot about electric yet as I had nitro. So here are some of my questions...

-what are my waterproof esc and brushless motors options?
-I have been looking at the hobbywing sc8 with the 2000kv motor. Ya or Nah?
-will I be able to run a single brushless motor on the dual motor setup that my erevo currently has?
-If so do I need a special motor mount and is there a cap that I can purchase to cover the 2nd motor hole?
-Will this require lots of mods our is there a fairly simple option?

Sorry for all the questions, but I want to do this right
