30 minutes of flying between storms


Waypoint navigation is pretty useless on VicaCopter because:

Flight time is too short to go anywhere.

Open spaces R too small to go very fast.


Advantages:

Don't have to manually set up every hover.

Just swap batteries & go.

Previously we tried setting waypoints in flight. GPS proved too unreliable to pull that off & the user interface was too confusing. One flight's waypoint was another flight's tree. Now hard coding pragmatic waypoints is the key.

Maximum flight time with flybarless is 11m30s so it added 1 more minute. The kit battery is abysmal.

None of the software heading hold strategies worked. They tended to not allow any yaw control at all & rapidly drift, making for very exciting flying.

Now seeing much less vibration without the flybar. IMU drift with flybarless is too good 2 B true. Unfortunately, the last 3 campaigns had significant oscillations in autopilot & manual cyclic was very unstable. Oscillations R in the 2 sec range, hardly what we expected with flybarless.

Autopilot pushes target attitude all the way over with no response from the cyclic. May be more yet to discover about flybarless dynamics unless it's blade tracking.
