Hi Dragon Tamer,
may be your question is simple for you - it's not simple for me, and obviously not simple for other forum members.
So how would you control a battle ship using sequential control (via a decade counter)?
Before you are through with a sequence your valuable battle ship could ram a quay and sink.
Secondly, how would you stop the 4MHz clock in time to have the counter stop?
Also the 4MHz you were talking about is just the frequency you use to clock the counter. There is some distance between you and the ship which must be overcome by some means of data transmission.
A general way for R/C model control is using an R/C set consisting of transmitter and receiver with connected servos.
You might think about using modulated IR, which requires to have the model in sight at all times, an omnidirectional IR-receiver and an IR transmitter strong enough for several hundred meters range. (Be prepared to carry a truck battery for transmitter operation.
)
Multi channel R/C sets are affordable nowadays other than in the early 70s, when I had to pay 1,800DM (Deutsche Mark) for a 14 channel digital proportional R/C set with seven servos, deducted by 40% for export. (normal sales price 3,000DM)
Remark: 2 R/C channels are necessary to control one function, e.g. rudder left and right.
BTW, under no circumstances mount a 38colt in the alpha turret of your battle ship. A friend of mine almost shot a pedestrian doing that with his "Bismarck".
