Flying out of the garden tonight with battery #2, had already flown with battery #2 a few minutes earlier but it was a bit too early for the sunset. No wind, temp must have been around 3-4C. Auto take-off from the same surface as a few other flights, glass topped table.
Props only spun fast enough to just lift it off the table. I realised something was adrift so straight back on the table. Tried a manual take-off, seemed better but I didn’t trust it and brought it down.
Insert battery #3, up up & away, no problems. Airdata logs below if anyone can explain why it just didn’t want to take off?
Auto take-off - problem
Manual take-off - seemed OK but didn’t trust the battery
Auto take-off with battery #3 for 8 minutes
