Pocket Sized Posted May 12, 2016 Posted May 12, 2016 Basically what I'm thinking is this: You have a stick with 4 springs connected to it. The springs are connected to the joystick base on rails that allow the ends to move in and out. You set up some sort of servo system to tighten the springs as airspeed increases. Pros: Simple to build (in theory). Adaptable to nearly any joystick. Simple to interface with the Sim (servo/motor position varies directly with airspeed). Provides realistic stick forces, which is usually all you're going to feel in an actual airplane aside from trim. Cons: Probably gonna be big (not an issue if it's a center mounted joystick) No idea what you'd drive the springs with. R/C servos could work but are noisy. Can't simulate trim properly. Idk, I'm just brainstorming. Could this be improved? Any similar ideas that would work better? DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.

I had a force feed back stick back in the late 90" I remember it being pretty strong. There on Ebay you could find a cheap one... [sIGPIC][/sIGPIC]
98abaile Posted May 12, 2016 Posted May 12, 2016 I had the same idea for force trim. A lever attached to the axis, the lever is between two compression springs partly compressed and a lead screw to rotate a bracket that encloses the springs.
