    How fast would you guess this is?

    I'm relatively new to boats, and have yet to get a GPS, but any guesse on how fast my Impulse 31 is going now in this video? Seaking 180amp, TP4082-2180kv, M445 prop, 4s2p. Think I'm pushing 55mph yet? Also, I'm open to any setup suggestions, I'm guessing I need to bring the strut up a touch maybe to stop the wobble, especially when I run back along my wake, I had it down a bit because it was a bit choppy and windy the day before. I realize I'm probably close to the limits of this hull.........

            For that motor combo I would run a 447 prop. With a little cup in the tips of course.

                Looks like a pretty fast ride to me.

                I don't think they ever look fast on camera compared to real life though. Always more impressive in person.
                It could be faster than my guess too...it's just a guess.

                    I calc it to 51mph & looking at the vid looks like around the same area to me.

                        looks around 48 - 50

                        looks like the turn fins are in the water on the straight runs ?

                          for my opinion the top speed is about 70kmh so less than 45mph...
                          anyway you're at the hull top speed limit....
