The design of the P8 Compass is complete. Our design incorporates a working top ring which turns a rotary encoder. This provides the required simulator interface while following the original design outline accurately.
I had the same compass installed in my Tiger Moth, No.82871. I must admit to cheating with SkyDemon on iPhone rather than trusting that ancient piece of equipment to guide the way!
Apparently it was designed for Naval use and not terribly precise as a navigational instrument in a fast moving fighter aircraft. There is a nice users guideline provided by the Air Combat Group.
It is such an iconic part of the RAF cockpit though, and I think our example came out really nicely!
