Autopilots
Hi Doyle,
TruTrak autopilots are a whole family of units, from basic single axis to three axis IFR units that fly approaches right down to the concrete. This company has a lot of experience. Their servos are high quality stepping motors and their units can be upgraded later on to additional features. So far EZ-Pilot only has one model single axis control head and is using the Navaid servo which is not comparable to a stepping motor.
