    Any Alpha drivers out there with active bow planes?
    How effective are they at death keeping?

    I keep breaking them off, so they are not being used at all now.

      Yeah! .. me!

      What's it to you, you Northern born, squid-throwing, bacon munching, Queen worshiping artifact from the glacial era??















      Bow planes are perfect for fine depth-control. But, as with any submarine, they are only an asset if the boat is properly trimmed for submerged operation.

      In fact, my 1/72 ALFA was working perfectly at the just concluded Groton get-together -- I hardly had to touch the stern plane knob. At least that was the case till Bill Lambing performed an unprovoked, evil, dastardly ramming attack on my boat by an evil American ASW platform. The ******* took out not one, but BOTH, of my boats vertical stabilizers.

      Commander, Red Banner Fleet has endorsed an angry letter that will be posted to the American embassy!

      We, the proud, peace-loving People of the Socialist Republic, DEMAND SATISFACTION! If not, we'll start by bombing Canada, (why not, it would be the perfect warm-up act) and then work our way southward. Or, you can send us Lambing's head, on a platter if you wish to deescalate from this razors-edge of world destruction a unit of your pirate-navy set in motion last Sunday.

        Dear comrade butthole ski mr. Lambing is an American citizen there for America's problem please do not threaten the peace-loving pot smoking bacon munching squid throwing Monarch worshipping butterfly and despot ruler with violence we absolutely will not tolerate this and will probably send a strongly worded letter of Our Own while on the subject how about a retract system do you know of anybody who has bothered with this or model it either in or out use or not bother?
        I I've run a 196 scale Alpha for several years now. Using only Stern plans and don't usually have much trouble maintaining Periscope depth I was considering making the bow planes on a 72nd scale boat functional and retract but just wondered if it was practical

        P.s sorry I was not able to make Groton this year hopefully next year

          There!

          Now that the pleasantries have been addressed

          The smaller the model, the quicker the response curve to yaw and pitch commands. Confirming your observation about the good depth-keeping ability of the tiny 1/96 ALFA. That too was my observation when I operated one well over ten years ago.

          I do find them useful (bow or fairwater, don't matter) on any boat over 40" long.

          I have not worked out a practical retract device for the ALFA bow planes, but would be a good idea, if for no other reason than to minimize handling damage when out of the water or running on the surface in traffic. If you do, keep in mind that the port and starboard planes are staggered a bit so they can retract laterally.







          Was just not the same without you, pal. Next year!

            RC Sub Workshop made a brass retract system for the Akula and Alfa.

                  Complexity Warship on display!

                  One cam, two pins, a pushrod between a pin and inboard end of a plane and you're done. At 0-degree the planes are extended. At 180-degrees the planes are retracted. Duh!

                  Wow!

                    It does look like a rube goldburg machine. I couldent see how it worked. Dave could you post a pic of what your
                    discribing?

                      Yes please, could you post your version of how it could be done?

                        Hello
                        Any chance you could put together a drawing OR a sample of the mechanism Please!
                        Thanks

                          You try and make a sketch and we will throw in our ideas to.

                            Captains, just go to Ebay and look at the close up pictures on the site https://www.ebay.com/itm/RC-Sub-Mech...IAAOSwBLlVA~jN
                            I could post them here but they're larger and clearer on the site...

                              Thanks! Nice pictures of the mechanism.

                              No Sketch off? :(

                              My thought was a single actuating rod that moved forward and back for pitch control and rotation for extending the flippers (planes).
                              The gear rotation would push the planes out with cranks on a crankshaft.
                              When the planes were extended the rod would move forward and back to pitch the planes.
                              The gear would un-mesh in the up and down position of the plane travel and would not retract till rod\planes came back to centered gear position.
