The Use of ARTF Aircraft for Aerobotics Research
May 21, 2006
To this end the group has tested the autopilot with a number of ARTF aircraft an example of which is the robust and inexpensive Multiplex EasyStar typical of a number of aircraft in this class. The modifications required were minimal with the autopilot being installed in the cockpit cover.
Test flights proved uneventful with no aircraft specific tuning of the autopilot being required. The specific tests conducted were for the aircraft to return to the launch point at safe altitude on simulated failsafe.
It is our expectation that most model aircraft will come equipped with integrated autopilots, including GPS navigation (return to origin), and spread spectrum communications if only to ensure safe use of recreational aircraft by unskilled pilots - "litigation mitigation" if you will.
These features will serve to contain aircraft to designated safe flying spaces and return them to the vicinity of the pilot should they for any reason stray out of radio range.

VMC Autopilot (V2) installed entirely within the Easystar's Canopy
A brushless Hyperion motor was installed for these tests to give adequate power margin however the standard motor would give adequate performance as the current autopilot has an all up mass of 105gm including all sensors and cabling.
Launching the EasyStar
Aircraft returns to home launch GPS waypoint, hold altitude at 100', circle waypoint - await further command if the R/C transmission is acidentally or deliberately lost.
Pilot can switch back to R/C manual mode (pilot-in-command) at all times. Manual take-off and Landing with 2 other MAAA insured pilot /observers nearby out of camera shot.
Hyperion Y22L-2840 Motor with fixed prop 6" X 4"; also Florescent stripes on wings and reflector tape on an extended rudder "visual aids" to assist pilot and ground observer tracking.
