I hear you brother! That is EXACTLY what happened (and continues) here. It was the top rotor and inside the fuselage it was the right side of the rear motor set motor that malfunctioned within a few flights. Same thing — the stalled rotor, the blade strikes. And PLENTY of spontaneous lift offs bound for the sun or something.
In fact, as I reported, I got the motor swapped out and it's performed brilliantly all morning, apart from when we took it outside (there was no wind) my son lifted off, and it just zoomed skyward and disappeared over the neighbor's fence.
We reached "Big Chinook Down", and it looks okay (she's a tough old bird) but she's still prone to "going rogue".
Question S026 Owners: have these two behaviors also affected the smaller Chinook??
