Out this morning early Syma X5C-1 - [bumpers; landing gear; and no camera]. Weather - Sunrise with calm winds, 38 F with winds becoming breezy (3 to 4 knots) as the sun rose. Operations - burned 3 batteries practicing turns and 2nfros. Damage - Snapped off a landing strut. Observations - Switching from Low mode to High, I noticed that it assumed a very sharp nose down attitude at full throttle/forward. I had to keep a higher altitude or it would have driven right into the ground. After removing the landing gear I noticed that the quad didn't seem to have much oomph for lack of a better word. Blade check ok, gears and motors seem ok. Hmmm. I'm leaning towards a bad motor. It was fun but cold.
