Hi all,

I tried flying at night recently in my back yard for the first time.  I took my Spark straight up about 20 feet or so, and came straight down.  At one point during the flight, it appered that it was not going straight up, but it was very slight.  I hadn't touched the right stick.


As I approached the landing area, with the Spark about 4 or 5 feet off of the ground, it all of a sudden flew sideways about 5 feet, hitting a shrub and flipping over.  Luckily it sustained no damage.

Today I did a test flight in full daylight, and everything seemed to be fine.  I am wondering if it is possible that the outdoor floodlights around our house could interfere with the sensors.  The lights are that bright.  It has never to my knowledge flown eratically like this during my previous daytime flights.


Thanks.

If I am reading this right, it looks like I did move the stick to the right at 15.7 s, but that was at altitude, and I think I did that to correct for the unexpected horizontal movement.  It looks like the right stick stays at center as I am landing.
