Hi ernest2:

I have never thought about biulding a putput boat, I think it would be a kick in the pants, you would only need a single channel radio, and a very small servo to stear, I had one whin I was about 8, it took about 6 min. to start, and it would run about 5 min. go for it and let us know how it goes.

yup i think i'll try to make one. maybe about 15" long so that it's big enough to carry an rc unit. my only concern is that maybe the steam engine's too small for it. well i'm in the process of making my first engine, had one done last night but it got busted.lol.
thanks for the reply, i've search the net for an rc putt putt but none.

There were several articles in the English Model Boats mags in the 1980's about building this sort of thing including the history of them going back to the early 1900's when some really big ones were tried. If I remember correctly the most successful ones used separate intake pies fitted with one way valves fron a car windscreen washer system. The problem with them is that they go slowly most of the time with occaisional sudden bursts of speed. This is a design problem which the valves cured. Will post again if I can find the articles. Cheers, Ian.

one very important thing I remeber is that the out put tubs must stay clean, if blocked from palutons in the water it will burst the tank, thats why I don't have mine any more. And you must not use a full heat that will exspand, investagte the full.

To aid the search, they were often known as pop-pop boats as well.
Thinking back to the mag articles, the better performing ones had a chamber with a flexible lid, which increased both "suck" and "blow" at the expense (or maybe prize) of much more noise. The simplest "motors" were just a coiled tube that the candle heated, with the two ends both poking out of the transom, below water level.

We did some pop pops with our Scout Troop a while back. We used the copper tube type engine. I did install a servo for the rudder in mine, It did work. I wonder if a Kitchen Rudder would work with one? Something I will have to play around with.
Regards,
Gerald.
PS I think this should also be copied over to steam.

I'll have to take some picture of mine. I did it just to bust the guys in the club. I was the orphen, no live steam. At one of teh trade shows I picked up one of the larger Put-put tugs. Rigged up a rudder and a slide for the candle. 2 channels steering and speed control with stop. Not the best running but it does work. Going from stop it does take a couple of minutes.

KMOT Hi, thanks for your support!

The engine is a spiral of copper tube, is quiet, no noise. In a few days I will have completed an engine of the same dimensions but with diaphragm to hear the music of the engine.

A greeting from Spain.

Hey!, is simple, the tube is very easy to bend, making it firmly on a wooden or metal cylinder
