Hi all, I asked a very experienced pilot at the club to help me get the kinks worked out of my new build, a Volantex Ranger EX with Pixhawk and Ardupilot. I think the throws of the control surfaces were reasonable and the CG was good according to the manual. Battery weight was high with two 5000mah 4s packs. I thought the weight would make it stable, and wanted the autotune calibration done with real-world conditions.
took off in MANUAL mode with 50% flaps deployed and 100% up elevator. was not easy to gain altitude. Flaps set to 0% for the rest of the flight (you hear us talk about this during the flight) flew quite nicely but with not a lot of authority on bank angles. flipped to AUTOTUNE mid flight and really struggled to control it. went back to MANUAL, lost altitude and crashed in a field. not much damage luckily.
I’ve attached log files of the flight. Hopefully the community can offer advice on if the plane was setup correctly before the flight, and what I can improve before trying again? Thanks.
