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…
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…
Original Motor 3S battery: 20A full throttle 950g static thrust (10X5 prop)
E-flite Motor 3S battery: 22A full throttle 1325g static thrust (10X7 prop)
E-flite Motor 4S battery: 33A full throttle 2150g…"
"I did both, I changed the motor first (E-flite Power 15) and flew with a 3S power pack, the performance was better but not great. Then I changed from 3S 5100mah to 4S 5500mah and the performance is good, lots of power to climb and at 8-10A cruise I…"
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…
"Thanks for the input Ben. After much searching, and some simulation I am switching to 4S batteries. A static thrust test using 3s batteries and various propeller pitches produced results in the 1375g range for a 2700g aircraft. The 4S batteries…"
"I was finally able to complete the 2nd flight of my Ranger EX 757-3. My expectations were high, the results were less than impressive. After installation of a 450W motor, I expected to the current in the 40A range (Burst) for takeoff, followed by…"

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…
"Kieran - an unfortunate delay postponed my maiden flight, as a result the LIDAR-lite V3 I ordered has arrived and is installed. I do hope to complete the maiden flight this week and work out the initial tuning. Ultimately a successful auto…"
