    Dive/Sail Plane Question

    Can the dive and sail planes be combined into one channel via a Y servo connector? Is this possible or recommended? Never had a sub with working dive planes before, but I don’t care for separate channels. Thanks.

    Possible. Not recommended.

    Ganging of the two sets of horizontal control surfaces does work, but only in a vary narrow sweet-spot of speed, bubble-angle, and depth. Out of that window and the boat bobs up-and-down, almost uncontrollably.

    Surface effects and bubble-angle does a lot to move the boats center of pressure back and forth. You want those horizontal control surfaces to be slaved to separate input generators: Angle-keeper for the stern planes; and you for the bow/fairwater planes.

      In many cases it might actually be better to simply forgo the front dive planes and use stern planes only if you are not interested or able to separate the two channels. I’ve built an operated many boats that only had stern plane inputs for pitch control and they operated perfectly fine. Just know that you want to be submerging resurfacing on anything anywhere close to a level Keel.

ID:	149931 I have enough channels but I’ve never run sail planes. I’ll put them on channel 2 and give it a try. Anyway, it will look good running in the pond we have here and show folks who never knew rc subs even existed. Here is my turf, Big Spring in Huntsville.

            Spring fed. But, only restrooms are in the eatery places and parking is limited on weekends. Click image for larger version

              Where is this location? I agree with David, it looks wonderful.
              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                  And it's a target rich environment too!
