    Hurricane/Spitfire-type control stick?

    Does anyone know what the advantage/disadvantage of the ring-type (spade grip) control stick used on British WWII fighters might be (Hurricane left, Spitfire right in pics below)? Maybe the point was to allow you to pull with both hands?

    And not just on fighters, here's one from a Percival Prentice trainer.

    It does seem to me that it would offer more alternate hand positions and easier changing hands than a conventional stick. Anyone every see one on a homebuilt plane and/or have dimensions/drawings for making one?

    I suspect it's about alternate hand positions. Those sticks were also jointed differently from a conventional stick. For elevator the pivot is on the floor in the normal place, but for ailerons the pivot is in the middle of the stick so the top of the stick moves through a greater angle. Not a bad setup really, and gives more clearance for the pilot's knees in a narrow cockpit.

    Re: Hurricane/Spitfire-type control stick?

    Spade grips were used into the jet age in Brit tactical birds. It does ease hand changes, which are needed a lot in those busy single seaters. And, as Dana pointed out, it also accommodates the big angular movement of the "broken" sticks common in Brit fighters.

    This was all before HOTAS became the rage, and while many of the things in the cockpit were not electrical.

    Sounds sort of like a lot of our homebuilts. Tight cockpits, manual devices, maybe a "broken" stick with a spade grip is a good idea.

    I have thought about this sort of thing for my homebuilt, but decided to build with pivots down low and a straight handle to start. New stick with a spade grip would be easy. They are all around 6" OD, maybe 3/4" tube. Easy enough to experiment with for shape, tilt, buttons, etc.

    Re: Hurricane/Spitfire-type control stick?

    it was quite common in aircraft of the thirties and not confined to British aircraft. The early 109 had them for some customers and Russian fighters had them, too. Also has the advantage of a gloved hand fitting comfortably in them and usually found with hand lever brakes, common on British and Russian aircraft. Also used on shared-stick aircraft, such as Zeniths and my old aircraft, a Malmo MFI-9.

    Now that I think if it, this would a be great project for a 3D printer to then take to have cast in light alloy. Or I have actually seen some carbon-fiber reinforced 3D printing that might work well. It would be covered with grip tape in any case. Hmmmmm....

    Re: Hurricane/Spitfire-type control stick?

    Can someone explain how the aileron control mechanism on one of these works? I've never taken the time to figure it out.

    Thanks,

    Kyle

    It's like a Cessna control yoke at your knees with a extension going up.

    A sprocket on the aileron pivot connected to cables going out to the ailerons.

    The Quicksilver GT400 has a pivoting stick for elevator, with a modern yoke on top for ailerons (also common on many older planes). My friend had one; I always thought if I had a plane like that, I'd ditch the yoke, move the pivot down, and do a spade grip.

    there are 3d printed Spitfire style grips available for simpit builders, to full scale.I saw at least one Zenith which has a y-type stick, which had a half-circle tube welded on top to become a spade type grip.

    Battler Britton, that Jurca stick looks canted forward in the second pic. Is that your plane? Got a drawing you could share, even if just a camera phone pic of a detail of the plans?

    I put self-vulcanising tape, also popularly known as tennis racket tape, on mine. Gives great grip.
