        None that I can see. Maybe the stutter bump warning system actually works this time around? Stutter bump is supposed to warn you of low battery voltage.

          Yeah, on my UL-1's maiden voyage I hit the LV cutoff and never saw anything like a stutter bump. Of course it could have been my inexperience though. I learned to time my runs after that.

          Let us know if the handling is any better after 50mph...

            I am not expecting handling to be any better.

            I plan on trying a reverse rotation prop (x442r) to see if it helps reduce chine walk. Of course I will need to use a wire drive or reverse turn cable to try this. Reversing prop rotation will pull against turnfin side only. Hopefully pulling against turnfin side will prevent prop lift during acceleration.

              Sounds like a setup issue to me rather a prop fix..
              When they are set up loose and fast they will walk some, If they are wet they won't walk much at all and be slower as they are more glued to the water

                I ruduced AOA of sponsons on my older first generation UL1. That mod helped lots, but slowed hull slightly.

                      The best part about this hobby is trying different things to see what works and what doesn't work. I think trying the reverse turn prop will just make it more fun...especially if it works.

                        I hear ya!
                        that would be very cool if it does actually work and make the boat more tight on the water and still retain speed..

                          I just read threw that whole thread and very interesting stuff. I may try and do something along the lines that PC was doing with the batts through the sponsons. Very interesting how AoA and aerodynamics of this and I assume all hydros are very similar to those in aviation, maybe my 7+ years as an aircraft mechanic will help me out with this hobby a lot more than I thought.

                            Besides the cap can you tell any other defferences between the new version and the old one?
