      I don't sell stuff anymore.

      However, if you're talking about a SD for the 1/144 Trumpeter KILO, then you're talking a 2" diameter SD. Such:

          Oohh! I see. That's supper small! Agreed, maybe you can get a 1.25" SD into that Type-7. Tight fit for the 1/144 GATO. I'll help if I can.

          • Thanks David for the eye candy! Is that a single drive shaft converted to dual with the gears? How do they attach to the prop shafts, I see what looks like tubing, I assume for illustration? Any thoughts on a submarine that would accomodate a 2” that turns sharply? Maybe a boat with the props forward of the planes & Rubber(s). Most seem to be dual props so would need to convert single shaft to dual ising gears.

            • Great job.

                How do you get your fat fingers in that little cylinder?

                  Conversion from a single output to two counter-rotating outputs is done with the simple addition of an opposing gear that meshes with the single output shaft gear. Like so:

                  Here you see the only difference with the 1.25" SD motor-bulkhead is the inclusion of the opposing gear to drive the second propeller shaft.

                  The soft rubber tubing (silicon or latex) forms a poor-mans universal joint between drive chain elements. However, using this means of correcting for running gear off-set mandates that the thrust loads be absorbed at the after-most bearing points: The shaft strut bearings on the GATO; and the ball type gimbal on the Disney NAUTILUS.

                  That little KILO turns just fine! https://youtu.be/oc4XLg79QDI

                  Don't over-think this project!

                  • Thankyou “my lord”, invaluable information! The photos with your descriptions always tell the story, even for numb nuts like me!

                    • So my 1:144 Kilo Pool Trials went well on surface maneuvers, however, ballast pump was inoperable. Upon my return to my shop I found that my Tx settings had been changed. I mapped my ballast channel five to switch C. Somehow that got changed…..grrrrrrr. Will return for pool runs in 10 days.

                      • David, silly but I cannot figure how the second driveshaft with the opposing gear is anchored to the endcap? Hooe this makes sense.
