Hi hegykc,

I am also in the middle of a flight control (bf109/fw190) design. I have a few comments about your concept if you don`t mind.

The gas springs are not really suitable for this kind of an installation. Their characteristic is very flat, which means that the min and max. spring force is almost identical. Well, you plan to use a pair working against each other to center. They will not center. The stick will stay more or less where you left it.

Also you need to consider that the gas springs are not designed for this kind of an abuse. The manufacturers usually suggest 5 cycles per minute of usage and the spring lifetime is only a 20-30.000 cycles. Well it is only a good 20-30 hours of intensive flying.

I suggest to use metal springs + high quality hydraulic damping.

Best regards and good luck!
