Reading recent LML concerns about composite props, nose gear, and shimmy damper issues,
by mishandling on the ramp,
I had a suggestion:
Googled "motion triggered video" and found several IR LED and motion triggered cameras in the $80-150 range. These are intended for wildlife or spy cam apps, but still apply here. Seems a sign reminding that "you're on camera, when you move or touch this plane" might increase attention span?
