> have you seen and/or used the miniature flux gate compass sold by Jameco >for heli/model directional and heading control ? Have you considered it >for this ? (and is it legal in your country ? ). No: 1) I don't fly heli's. Planes are hard enough for my limited eye-hand coordination (boats, though, let me kick your butt). 2) I was only doing the work under contract, not because it was of particular interest to me. The pilot worked for FMA, too. Besides, they cancelled the project before I had anything to deliver. 3) Why would it NOT be legal?
