Re: [PSUBS-MAILIST] cockpit control pics

Hi Peter,

"Repeating others' success is easier than building a better mousetrap"

An occasional reminder of this and other basics is always helpful. I have re-thought many details based on this very notion and every time I am reminded, there is a design improvement.

The Ercoupe reference was simply an example of mechanical linkage for single yoke / stick, three axis control for anyone so interested. I wouldn't give up the pedals on an aircraft but I imagine a sub doesn't have to worry about cross control issues causing much more trouble than maybe a little drag. My design wont have roll control at all.

There is a 3-axis joystick that moves left-right, forward-back, and up-down. Don't remember where, or who made it, maybe it's on Deep Rover or the Martin Marietta Manned Maneuvering Unit.

Regarding Ercoupe, many have been converted to use rudder pedals.

Repeating others' success is easier than building a better mousetrap.

I'm thinking of a control stick like aircraft, but to one side (out of the way) and with a twist. Why not control all three axes from a single stick? Push/pull for pitch (like an aircraft elevator), left/right for roll (like aircraft ailerons), and twist for yaw (like aircraft rudder pedals). This could eliminate pedals which would enable an exit hatch in the floor for my ambient dry sub.

Sounds good, but I suspect somebody here can troubleshoot....

Thanks...

I've got pics of about half a meg apiece of my steering wheel/control stick options.

I don't know what's hapenming with Moki - jeepers that thing is awkward to use.

Anyhoo, anyone interested can let me know and I'll send them offlist.

These are game control steering wheels and a joystick. As far as aircraft controls go, they are extremely light. I'll be adapting them for use with mechanical linkage, probably drum and cable with eighth inch S/S marine cable around through bolted pulleys. There will be NO computer/motherboard/electronics aboard with the exception of my depth finder/collision avoidance. The usual electrics, of course (nav lights, red night lighting, etc.) I have a knotmeter, depth gauge and voltmeter. C'est tout.
