    Hi Doug
    The mesh on my Taycol was flat so not surprising it sparked so much. A friend who exhibits vintage models etc has my motor on loan at present so I can't upload a pic. The special had extra coils so could be reversed by connecting the battery to one of two connectors to reverse the field coils. I see the extra holes are on your paxolin end formers. The extra field coils did make for a heavier motor but a simple relay could be used to reverse direction. This was a big bonus in the 1960's as the radio was not cheap and multi channels were not that common.
    Happy days

    Hi Dave,
    "I did suspect that the modification to work with modern RC would have had a beneficial effect."
    I recall that we had a discussion about this effect a few years back (2018, in your Dave M incarnation ๐Ÿ˜‰) while I was restoring/modifying Colin's motor and my Target.
    I guess you only had chunky germanium diodes available back in the sixties?
    The early silicone diodes were relatively low current as I recall.

    Have had a dig around and found some pics of the restoration and a short vid of a test run.
    Attached a few Before and After pics.
    Site rejected the test vidโ˜น๏ธ I'll try it in a separate post. (More time wasting. Grrr๐Ÿ˜ )
    Unfortunately I have no vid of the pyrotechnics before the modsโ˜น๏ธ
    Cheers, Doug ๐Ÿ˜Ž

    This is my Sea Commander which I built a few years ago. Brought her out a few days ago for a new prop and for Alice to re-battery and here she is on the lake earlier today.

    Hi Colin, great to see yet another of the classics restored and now getting some use. I hope that I am able to finish my own Sea Commander to such a good standard.

    I agree with your comment regarding the battery weight. Whilst the speed may well be scale like, the boat does appear to sit fairly low in the water, so I believe that a lighter battery would definitely be a good call as it would increase freeboard.

    Overall though, a great looking model, well done and time to enjoy it now. Will

    Hi Doug
    I did suspect that the modification to work with modern RC would have had a beneficial effect. Only wish the modern diodes were about when I was using my Special. I bet the bearings have made a great improvement although the speed I used to achieve resulted in a most satisfying whine but did require frequent lubrication of the oil pads on the solid bearings.
    I agree it is a pleasure to see a Sea Commander and the motor all afloat and restored.
    Cheers,
    dave976

    Hi Colin,
    " I don't appear to get any sparking if the brushes are oiled correctly, only if allowed to dry out.
    I did a test at night without light and no sparking."
    There's a very good reason for that (or two๐Ÿ˜‰)!
    Mainly, the diode bridge that I used in the reverser box (to provide forward and reverse with a standard modern ESC) suppresses the sparks๐Ÿ˜Š๐Ÿ˜€
    I should have a test run video and scope traces somewhere (on an old PC) that show this effect. I'll rummage around.
    Also I machined and polished the commutator and brush ends for the best possible continuous contact.
    I trust that the ball races I fitted will also help to reduce friction and jack up the efficiency a little and thus reduce the current drain a bit ๐Ÿคž

    Very happy to hear (at last!๐Ÿ˜‰) that my efforts (from a corroded 'block' to a humming motor) were not in vain.
    Thanks for the credits in your posts ๐Ÿ‘ I had fun doing it but was glad that I had previously practised on my Target.
    My little Taycol Target which I converted before your Supermarine also does not spark.
    I'll see if I still have the photos and test run videos that I made during the two conversions. Some info on the Target conversion is in my Sea Scout Jessica Blog in case anyone else is interested in going this route.
    Very nice to finally see the Commander afloat.
    Well done. Happy sailing.
    BRAVO ZULU THAT MAN
    Cheers, Doug ๐Ÿ˜Ž
    PS to Dave976 (AKA Dave M) As far I know the brush mesh was from the 1960s. I certainly didn't change it, just cleaned 'em up and squared off the ends.

    Hi Colin
    Probably the modern mesh is better than I had in the 60's but good to hear you are running this motor

    Good evening Dave, I don't appear to get any sparking if the brushes are oiled correctly, only if allowed to dry out.
