    Jorg has been kind enough to provide some details on his record-setting hydro. He is one part fo the JAG's team - Arne and Gunnar Hold and Joerg:

    Boat: .......... JAG's T Hydro 2015/2016, 125cm long, 55cm wide
    Motor: ......... LMT 2260/5
    ESC: ........... Highly-modified Schultze 18.xxx with lots of big FETs added
    Battery: ...... 8s1p RoaringTop 5100 80C, charged to 4.23V/cell, prewarmed to 45°C
    Propeller: .... JAG's C2044/3 (exact same design which set the 140mph record in 2006)
    Hardware: ... 2.5mm piano wire with own design strut and rudder bracket, knife blade rudder

    Acceleration power of the second pass (185 mph average) was 590A @29.0V and flat out power was 320A @29.5V after about 4s of full throttle. RPM came up to 63,900.

    The boat has dual air brakes in the vertical stabilizers which cooperate with the proportional motor brake in the ESC. Total boat weight is approximately 7.5 lbs.

    I want to thank my friend Joerg for providing us with this information. Of course what he did not tell us about was the very hard work over the past three years which lead up to this record. Combining that with mostly custom equipment, his record should stand for a long time (unless he wants to try to top it himself - but then why should he?)

      Was there a reason he used RoaringTop Lipo's when there's many other brands especially now with Graphene, etc?

        What Jorg has done, both in terms of his setup and record is just nothing short of impressive!

          Simply put?? The best batteries I've ever seen on my charger... Seems a valid reason to me.

            Fasizzle that's a load of amps. The esc design is remarkable.

            Is there 4 wires on the motor or 6??? or 3? Looks like 4 in a few shots.

              Darin, really? I have a pack of 70c's. They're not exactly what I call impressive in terms of IR compared to others especially Revo's which are easily 2-3x less in IR.

                  Ummmm... OK... Believe what you will. What do I know anyhow... I've got no experience at this whatsoever.

                  Show me some numbers, because "easily 2-3x less in IR" is a REALLY bold claim.

                  This is just the second discharge cycle from 4.22V@40A, battery at room temp.

                      Sounds like you've got it figured out. So we'll see you at Legg next month?
