  • Krick U25: Refit and Restoration Log 2019-09-11

    The latest addition to the Fleet. The venerable Krick U25. A very simple, 3 channel Dynamic diving RC Submarine that is fun to use!! I had one which was in fact my first boat back in the late '80s.

    You can actually read an article about the loss of her, “Grey Lady Down; A Users Perspective” The SubCommittee Report, Issue 26, September 1996. Pg 41. I learned a lot that sad day.

    After restoration and refit with some modifications to insure survivability, and compatibility with modern running gear, she'll be a perfect go-to fun boat at the pond for myself, inexperienced people who wish to try, and children that may become future RC Submarine enthusiast's. The best way to bring people into this hobby is to join a local RC boating club, and hand someone the transmitter. Dave M. and Bob M. have no issue doing just that. I plan to run a “Subschool” with anyone at my local group who is interested.

    Her keel was laid by no other than by Jim Butt of Subcommittee fame, and I got her from Joe Oliver at this past 2019 Groton SubFunRun.


    First things first…..strip her down….clean her up!!!

    Ed, this will be a great WIP. I think your idea of a sub school submarine is a great idea.
    If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

      I second that. And if any non-qual's get out of line ……...… grease 'em!

        Despite the fact we've been running boats every weekend since Groton, and I find myself overjoyed on how well SSN-591 has been running, I've been finding the time to work on U25.

        She's been stripped of operating gear and all that grease the former owners felt to use since apparent failure of her push-rod seals, which was revealed upon cleaning.

        I also ripped out the old style "grease gun" stuffing box's, which will be replaced by my home brew dual cup seals shaft seals. That means I'm tossing the original 1.96mm shafts with L/H, R/H molded in plastic props. On order from the Prop Shop UK are two brass replacements that will use a 1/8" SS shaft (P/N V3011/3 BRZ scale props handed pair). The new Shaft tubes will only be increased by 1/32" in diameter.

        As you can see it took a wee bit of "surgery" to remove them. We may differ in our definition of "wee". You know what they say about egg's and omelet's. One should never be afraid to proceed!

        ANYTHING can be fixed.

        All the electronics, both motors, both batteries will be replaced. New lid as well as lid sealing system will be used.

        I'm printing 3D printing the new motor mount as I write this, I'll update in a few days. Now back to PROTEUS.

        Nice little winter project that will fill the gaps when I'm not working on the other boats.
