My house is in a heavy oak/hickory tree three acre lot wooded neighborhood. I've flown about twenty missions off my rear deck, climbing through the only "open canopy" area available... then doing neighborhood waypoints and orbits (usually Litchi).
One day last week after two uneventful and fairly lengthy waypoint runs, I just wanted to send her straight up off the deck to hover. It was getting dark and I wanted to show my wife the multiple Cree strobes.
Well, all heck broke lose right after takeoff. I was getting so much warning input that I was mentally overloaded.
Bird finally glanced off a roof gutter, inverted and crashed upside down on my concrete sidewalk, continuing to run and bounce upside down.
In doing so, I panicked and didn't think CSC stick shutdown. I grabbed the bouncing bird to pull the battery, and REALLY sliced up my left hand with the props. Not good!
Yes, those blades CAN cause serious injury and cut deep!
Well, it appears the only thing needed was prop replacement. Calibrations remained OK, and no shell cracks. Just had to wipe some blood off (yuk!)
Subsequent test flight a few days later (after prop replacement) went fine with video and pics.
But I cannot understand the sudden turn of events that took place at my standard location! No metal changes nearby, or anything like that. Just my private deck area!
I guess point E (WARNING! MOTOR OBSTRUCTED) indicates the first note of impending disaster, yet it has flown fine since the props were replaced (which was a result of the crash, well past Point E).
And I SURE as heck cannot understand the minus 1000 Feet + altitude readings noted on the below flight log!
Thoughts?
