I've got a race and need some help
Me and my buddy are real competitive. I have a spartan vxl-6s with 3s lipos, 5in dual pickup rudder, alum water jacket,dual water outlet, splash guard, 69mm turn fins, and adjustable trim tabs. Well he said "Don't worry Ive got something for you". I know its a catamaran of some type. What else can I do so I don't have to worry about him beating me. I was thinking about getting a CNC prop but don't know which one. Also what else is there to do get a new esc and motor? I've got 2 weeks before he will be ready.
