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 "Auto Mode" as well. Finally, everything is coming together for…Continue

I finally completed "AUTOTUNE" and "AUTOTRIM" activities on my Ranger, after fixing a self-induced configuration mistake. Once "AUTOTUNE" was completed, FBWA mode flights were stable and responsive, ready to test an "AUTO" mode mission next. Once "AUTOTRIM" was complete I ended up with a nice "MANUAL" mode trim and stable flying…Continue
Finally had the time for the next flight. I increased the Roll and Pitch gain settings as the first two flights were quite sluggish to control inputs. I was hoping to complete the "Manual" mode trim setup this flight but I continue to have too much starboard roll for the trim setting on the controller.
I completed the maiden flight of my Ranger EX 757-3 today, with mixed results. The flying weight today was 6lbs, using a standard rule of thumb, the power requirements would be 450 - 600W. The supplied 3715/1000KV outrunner brushless motor only provides 300W.
Update: The local weather is improving and looks like tomorrow will be the maiden flight, really looking forward to its first flight. The field I have selected is grass, and I have increased the main gear size to 4.5", which I…Continue

For my maiden flight, takeoff and initial tests will be in the FBWA mode. Followed by switching between FBWA and Manual to get the trim correct.
Some basic gain/dampening factors for the first flight, except for…Continue
