RE: co-pilot?
Learn to fly without electronic help. You'll be a better pilot. Don't take shortcuts in the learning curve.
When I flew my first 1/4 Fokker Dr.1, I used a gyro on the rudder, mainly for ground tracking during takeoff and landing. Sure, it helped. However, after several flights, I took it off and simply learned how to fly with the rudder. Now I'm a competent rudder pilot, and it helps considerably in windy conditions.
