So…I was out flying, around 430m height, and all of a sudden I lose directional stability. Then I notice the altitude decreasing? Weird. I push up more to maintain, and the craft responds. Direction steady, all good. 10 seconds later… All heck breaks loose and I’m just seeing props, body, Sun… And I know something just hit the fan. Altitude is plummeting. I’m at like 40mph… Going down. Then nothing. I’m in a snow bank.
Thank God I got the 8" of soft fluffy snow otherwise it would be a write off.
Post mortem: one Chip missing from the ESC, solder melted clean off. Wires to front left motor got toasted, all melty. Burnt windings in motor.
Question: what was first… Blown ESC or damaged windings?
Is there any way to see?
