Another
Bert Persson masterpiece from years gone by ...
In gliding mode with prop feathered.
The
cowl was opened during engine run and closed on shut down.
Digital
video wasn't around in those days! The configuration shown
wasn't too bad. However, imagine a wing-tip mount of the
camera counter-balanced by a weight slung under the opposite
wing (so as to be out of view) and then doing aerobatics!
