Re bending.
You're right - it's to do with the quality of the camera and the effective framerate and/or shutterspeed (ie low on both counts). The camera I used is quite literally the size (and shape) of a Zippo lighter. Not bad considering...
Notice that it's most exaggerated in the first clip yet there isn't any in the second clip (because it was taken with a much higher quality camera).
(FYI Thumper, the photo with the bendy TR was actually taken at the summit (rotors turning), whilst waiting for the skis to be unloaded!)
And to 407 Driver:
The wx was indeed incredible. I arrived in BC expecting a -20C Canadian winter but on that day (as you can see) there was unlimited viz and even calm winds! The snow was 3 days old but we still had fresh tracks all day. Divine.
Safe flying all,
