Best viewed at 144p for highest bitrate. This is the 3rd flight of the Mojito.
iNav had lost some of my settings before the last flight which made it less stable and less responsive. Fixed that, cranked I-terms up some more. Straightened the twist in the wing. Added some more useful OSD elements like the speed so I can test its limits.
Launched LoS in Acro mode with it pointed about 40 degrees nose up. Still dropped the nose a bit and I am not launching it wings level. Still not entirely comfortable with the idea of launching from flat ground, but will get there.
Current reading is about 15% low.. still dialing in the current sensor scaling factor.
The value just above flight time is W*h/mile to get some sense or efficiency, although I'm not really flying it that efficiently. Highest efficiency is probably at about 6A draw and 50mph or so.
Below are the markers for the various tests I performed including top speed, power off dive, slow speed, manual mode, cruise mode, RTH etc..
Two issues. Motor isn't braking enough so it windmills and slows me down while diving power off. Nose bob in RTH mode. RTH seems to have it's own stabilization settings and don't have much experience dialing them in.
