    RE: Need opinions on what could be wrong

    Hi Peter,

    I noticed in your opening post that you set the ESC's at a soft cut-off.
    I accidently had done this at one of my ESC's and the runtime was 'dramatically' short (2-3 minutes),...

    RE: old Robbe Diabolo help needed...?

    Hi Colosus,

    I assume you know the 1300-9 needs watercooling on both can and brushtabs, to keep is alive on 20-24 cells NiMH or 7-8S Lipo?

    RE: old Robbe Diabolo help needed...?

    Hi Colosus,

    A large 920mm hull doesn't 'need' a flexshaft, a solid shaft will work just fine, as long as it's long enough to keep the propshaft angle at a minimum.
    The angle doesn't need to be...

    RE: Prince 25

    Nice work Bass!

    I noticed in your previous set-up that you cooled the motor first and the ESC last, I'd reverse that in the current set-up, as the motor heats up the water substantually more...
  6. RE: turborix 2.4 tx will not set with forward only esc, pls help!

    Hi PM,

    If the ESC in question, or the TX at hand, gives you so much 'trouble', why not get another cheap tx/rx set from HC for this boat (and other boats that don't need a selfcentering stick,...

    Hi PM,

    Did you consider a ratchet for that stick?

    I have one on my transmitter and use it for speedboats (forward only) and scale boats with reverse alike.

    RE: RE Hobby King radio 2.4

    Hi Larry,

    For scale and sail they work fine.

    It may be an idea to get a seperate receiver for each model, to save time and trouble swapping from boat to boat.

    What you describe is typical for a surface piercing drive, as your boat has, it's called propwalk; the rotation of the prop, combined with the fact only one blade is in the water, will...

    Hi Madworm.

    The Shockwave and SV27 are well known, the V24 is the most scale looking boat, but it has the same motor as the much smaller Arpro, the 3635 1520KV outrunner is way too small for...

    RE: LiPo Q

    Hi John,

    Running lipo's in a 'hot' set-up requires pre-heating the lipo to 40°C prior to the run, failing to do so may result in bloating.
    This is a 'normal' response of a Lipo that's been...

    RE: ESC Help

    Yes,

    A watercooled 100A ESC is sufficient for the 1880KV motor.

    Short leads between the Lipo('s) and the ESC are also important.

    Our moderately set-up Arowana's run 65+ km/h (40+ mph), with a faster motor, or a 5-6S Lipo 50 mph is possible.
