Okay, so I placed an order today for a Brand new UL-19. I'll be racing it mostly at a club/pond in Michigan. I know for a fact no one there runs one in the class. It will be 4s. I want to come up with a list of what I need to order and get on the boat (to maybe run a bit before the snow and ice show up... So, I'm looking for anything I can rob from your experience. Like I know I need to order a rear motor ring. I also need the lock ring so I don't lose the cable... What all else do I need to change? The HD flex cable and coupler? Any good tuning videos out there either General RC hydro or UL-19?
