      I raised my strut maybe 1-2mm and I noticed a nice jump in speed.
      And I have everything sharpened to kitchen knife status
      gps last night 43.6 with stock prop.

              Stupid newbie question: When adjusting the strut, it seems like you have to bend the stuffing tube. Is that correct? Is there a risk of fatiguing the tube and having it fail on you?

              Thanks.

                  I have never had a problem with stuffing tube when adjusting
                  The strut. Water test in bath tub. Use loctite on coupler on this boat. Famous

                    For speed run adjust turn fins up alot ( away from the water ). Boat still turns well

                      Just make it parallel with the hull bottom and run it there. I will measure mine tonight. (8.21.2013 hull on flat surface measured up to the center of strut hole .400") Look at Revolt Redone it has a great shot of strut height.

                          Can you please elaborate here?

                          I'm running the same starting setup as many in this thread it appears.

                          Stock Revolt motor, ESC
                          (2) 2S 5000mAh Turnigy NanoTechs - set for 30% COG
                          X642 S&B
                          Turn fins all the way up and angled forward (still turns on a dime, doesn't slip)
                          Left outboard trim tab angled down just a touch in attempt to offset the right pull the boat has (had to still trim rudder quite a bit left to keep it straight)
                          No adjustment to strut.
                          Rudder sharpened.
                          Using Spektrum MR200 and DX3C.
                          Garmin Forerunner 101

                          My GPS said 45mph one day using the stock prop. Never seen that again.
                          Another day it said 30mph.
                          Today it read 35mph on one run, a little less than that on another run.
                          On yet another day, it was low 30s on one run and then re-armed the ESC on the next pack as expected and it hit 40mph.

                          No major differences in water surface/chop. Pretty darn smooth to very light wind ripple.

                          When I plug in my packs with radio throttle trim set middle, it beeps about every 1 second. I unplug, adjust throttle trim down one click at a time, then plug back in. Keep doing that until the stock ESC does the single beep thing, then I pull full throttle until it beeps again, then let it out to neutral, where the ESC completes the arming sequence beeping.

                          To me, either those Turnigy batteries kind of suck (individual cell voltages don't support this, but I'm no expert) or the ESC isn't setting up right. I have 4 packs of the 2S Turnigy Nanos and 1 pair of Hyperion 2S 5000mAh. I have yet to try the Hyperion due to time but will be hopefully later this week.

                          (8.21.2013 Place hull on flat surface remove prop and shaft. Now measured from the flat surface up to the center of strut hole mine is @ .400")
                          Checked this a week ago or so and pretty sure mine is the same. I'll double-check again.

                          What am I missing?

                            The variations in top speed are most likely due to the throttle calibration you need to do every time you power on.

                            I'm using the DX3S with an MR200 in my Revolt (it's for sale in the swap shop!!) and never had to mess with the throttle trim to get the stock ESC to calibrate. I changed out to a SK 120A early on, for a few reasons, so I don't have a whole lot of experience with the stock ESC though.

                              Hi Rick, saw your Revolt on the swap, nice-looking package!

                              Just don't trust the stock ESC with that re-arm thing.

                              So you had your throttle trim set to middle and it would arm?
                              If so, I'm going to start over and rebind the MR200 to the radio and try setting it all up again.
                              As it stands now, the throttle trim has to be set about -5 to get it to arm.

                              I have a Seaking 180A that I got randomly for a good price that I'm thinking about swapping into the boat just for the hell of it, as the re-arming thing on every pack change for the stock ESC kind of sucks, not to mention that I can set the LVC on the Seaking to what I want. I time my runs anyway to drop to about 3.6-3.7v on each cell, but having the backup feel-good LVC on the Seaking doesn't hurt.

                              I'll mess with it tonight and see.

                                Try callibtating throttle. hook up the motor, receiver and esc.
                                turn on the radio and the receiver (if you are using a seperate receiver battery. (you should be)) (if not, just continue to the next line with the transmitter turned on.)
                                pull the trigger to full throttle and while holding it there connect your lipo battery up to the ESC.
                                you should hear APROX. 3 beeps, then IMEDIATELY release the trigger and you should hear a confirmation beep.
                                unplug the lipos from your ESC and you are done calibrating the throttle.
