Hi Paul, Congratulations on a low cost answer to getting some effort =
into control forces.
Steve, the set up you describe will work fine. I already mocked up a =
lower tech version for rudder pedals using a pair of small cycle pumps =
linked by rubber tubing and a restrictor clamp. The cycle pumps have =
light springs fitted inside the casings to provide a little self =
centrering. The type of pump is the small emergency pump about 9" long =
and 1" o.d. I'm sure they sell the same thing in the States.
Regards, Brian West.

Hi all
I have been working on a control/feel system without using =
springs/hydrolics etc and have come up with the following.
This is a DIYers dream ! cheap , free for me I had the bits !
Take a piece of 40mm plastic pipe make a piston from a piece of 15mm =
dowel two plywood washers( nice fit in pipe ) fastened to the dowel =
either side of a piston made from foam used in the UK for lagging copper =
pipes.=20
The foam for 15mm pipes is a tight fit in 40mm plastic pipe , with a =
piston made from a 100mm length of foam I cannot push it down the pipe =
with 50mm it moves smoothly.
There is no tension when the system is at rest and the force can be =
tailored to your needs by the size of the foam piston.
I may then put a bungee on with just enough pull to slowly move the =
piston.
regards paul
