Ranger EX 757-3 Auto Mode Test

Completed a successful "Auto Mode" test today using a simple rectangular circuit.  From the "CTUN" graph you can see the roll and pitch response matches the demand.  The aircraft flew stable and as expected, I also repeated this test using 2 different altitudes verifying throttle, airspeed, and rate of climb in…

Ranger EX 757-3 (Auto Tune & Auto Trim)

Maiden Flight of Ranger EX 757-3

The GOOD:

  • Initial parameter selection flew the aircraft safely and successfully in Manual and FBWA! 
  • The build was good (no bits flew off)!
  • All the systems checked…
