Here's bit closer look at how the guy is attached to boat as well as how the ores are hook together.
I had seen one of these in action when I was just a small child and have always had a fascination with them.

The propeller is attached to a small shaft that runs through a barring and continues on under the boat.
Unfortunately I've only completed one other which is located out by the garden in an attempt to scare off the birds.
A microcontroller takes the throttle and rudder signals from the receiver and converts them into synchronised drive signals to 4 servos.


The little boy in the front has a pretty good size fish on his line although I'm not too sure how long it will stay there before it snaps the line.
The main shaft has a piece attached to the other end with an off center hole for the main activation rod to hook to.
It's made up of a bunch of scrap parts I had laying around and has a small telephone bell on the back side. I have had all the pieces for at least 4 years and even had it slapped together at one time to give it a test run.
The tail end is much longer than the diagrams shows and helps balance out the weight of the propeller on the front and also has a vertical fin to keep the whole thing pointing into the wind.
If not and you like whirligigs it might be worth watching it just to get a look at 'em.


I must say it worked great although I'm sure it will need some maintenance from time to time. I plan on placing it off to one side of a small TV antenna tower I have and this first photo is similar to what it might look like from the ground.
