[ARC5] Biggest Radio Controlled boat?

[J. Forster]

That kind of control was called a 'clockwork mouse'.

Also, a battleship turns kinda slowly, unless under a lot of duress.

> Control may have been like the old "rudder only" control on model

> position one pulse would cause the rudder to go one direction (say right).
>  The next pulse would return the rudder to center.  Then, the next pulse
> would cause the rudder to go to the other side (say left).  The next pulse
