    I've been away from simracing for a while and have been revisiting WWII combat aviation.
    I have started work on Spitfire controls for me to use in my simracing rig and my oldest son for whom we are gonna build a Spitfire style cockpit.
    I'm stuck at how to transfer the aeliron motion to preferably a hall sensor.
    The movement is a total of 90degrees from right to left and a link in the chain moves about 65mm.
    The bolt does not rotate.

    That sounds interesting! I never heard of those. It can also be useful for the brake lever for the landing gear.

    Large slide pot attached at one end of the chain?
    Pot attached at or near the centre bolt with an arm reaching out 90degree and then back towards the centre hub @90 degrees.

    I even went to the trouble of photoshop for you, not my forte mind ;)

    Thanks for the effort! Those options has crossed my mind and I could use a 60mm slide pot if I reduce the travel to 80degrees to give a total movement of a chainlink to just under 60mm.

    if you want to use a hal sensor you could drill the centre bolt out so that it stays in situe but is hollow, insert a spline conected to one face , with the magnetic tip on the other , thus causing the rotation , then make a mount for the sensor

    If you go slide pot you can get a longer one no need to reduce the travel unless you really need or want to.

    If I understand what you mean it would require the bolt to rotate but it doesn't. I could on the other hand do a similar solution to what Not Lifting Off described and have a hall sensor positioned at the end of the bolt and an arm that holds a magnet that rotates around the sensor. Would that work or would I always get the exact same reading from the sensor since the magnetic pull would be the same all the time? Would it be a better option to have two magnets, one positive and one negative, one getting closer when I roll right and the other when I roll left.

    the sensor reads the change in the polarity N/Sso you either have the magnet n/s fixed in a static posistion and the sensor rotates , or the sensor fixed and the magnet that rotates

    That makes perfect sense!=) My first idea would then be completely useless. I'll go ahead and order a BBU836X from Leo Bodnar and some 1301 and 1302 hall sensors and magnets and do some experiments.
