The light was fine.
Bright sunny day.
The AC doesn’t get above 4ft before it throws itself to the ground.
It’s quite violent
The first time it happened I thought it was trying to self destruct.
I know this is an old thread, but I thought I’d update my experience with my seemingly self destructive spark.
After much study and frustration I noticed that the front right motor seemed slower to spin up.
I replaced the motor and the Spark has resumed normal behaviour.
I can’t even begin to express the lengths I’ve gone to to resolve this issue.
The difference in motor spin up was very minimal. Wondering if the extra load of the motor was creating the battery fluctuations.
Back to being happy with my Spark.
Hope thus helps someone else.
