    I am thinking of fitting front dive vanes to the skipjack since its not static dive what your view on this

    I've never yet had a sub with working front planes, although this one does have the option...at present they are fixed, but one connection and they can be working.

    Hook the front planes up the servo controlled from the tx, and use a leveller on the rears...that'll work nicely.


    (just thought...I lied. My Neptune had working front vanes...)

    No, I've  never used front dive planes either.

    I think the general rule is stern planes to control angle and bow planes for depth control.

    That is alright when you have a crew onboard but bow planes are awkward for we modellers (linkages etc.)

    I don't have much experience of "pure" dynamic divers though but I think that this would still apply.

    I do use bow dive planes, in the case of my Skipjack the sail planes. They are set up so the bow planes are depth control and aft planes are leveler.
    That being typed, on the first pool test for the Skipjack, my sail plane connector would not connect. The sail planes were put in a slight down position. She handled great using speed and or the leveler adjustments.
