      Had to jump into a little way back machine for this one- video link provided by Richard Jenkins in connection with a project to build a pop-pop boat with a R/C kitchen rudder. He formed a wad of aluminum foil into a cup shape to see if it would make a little pop-pop boat backup, and voila it worked! Two servos would be required for a real Kitchen rudder though and cheap R/C cars usually have two reversible motors for skid-steer control instead of servos and tie rods.

In the past I've seen RC cars at walmart for ~$6 that had foward/reverse motor control and left/right steering control using two control sticks. Need to get one and see what could be modified for pop pop boat use.

        Yep, there are a lot of tiny R/C gear options these days. Most toy departments have something cheap that will work. I am using a Spektrum micro brick because I have a couple laying around. But a lot of the $10-$15 micro cars have actual tie rod style steering and could be used. Also micro airplanes and helis like AirHogs or Revell from Walmart. The only things you need to be careful of with micro cars is that some of them have extremely short range (like 12 feet).....and some inexpensive planes and helis use infrared transmitters which may not work very well in the bright outdoor sunlight.
        My Spektrum receiver/servo brick is about 1"x3/4"x3/8"...including the 2 on-board servos. The battery to power the RX and servos is a single Li-Poly cell, smaller than a stick of gum. All in all, a very tiny package which should be suitable for pop-pop steering.
        The small boats I have with rudders seem to steer fine. I have one that I trim to run in the kitchen sink, tight circles with about 15 minutes running at full speed (flat boiler), then another 10-15 or so at half speed as the candle burns. That one gave me the inspiration to R/C version. I also noticed you could control speed somewhat by moving the candle fore and aft. Seems simple enough to use the 2nd servo to just move the flame.
        What I am really aiming for is a small "control module" that I can pop out of one boat and into another. Save on cost that way, since the Spektrum RX/servo bricks are $60.
        I've seen some photos of gorgeous R/C models powered with flash boilers. The small size and simplicity intrigue me.

        BTW: I was dubbed Weird Jack about 15 years ago by the online slot car community. I manufacture slot car tires as a sideline.

          Go to http://en.wikipedia.org/wiki/Kitchen_rudder and consider the possibility for a unit similar to an outboard engine that could be attached to the transom of any tinplate boat large enough to hold it without sinking.

            An "outboard R/C" was my initial thought. The rx/servo brick is tiny enough and it has 2 servos (so a kitchen rudder could added to such a unit).
            My own goal is not to retrofit existing tin boats, but to build tiny R/C wooden steam launches 6-9 inches long, designing one micro rx/servo brick module to fit in all of them. Although I would love to drop an R/C brick into a Victoria boat or a Webley Super Cruiser.

            As an aside: I read somewhere online recently of a guy who was going to market an patent and "outboard pop-pop" engine. Now I can't recall where I read it.
