For me the regular automotive creepers designed to be low to fit under cars were too low to comfortably work under the airplane. Reaching the underside of the wings and belly of the plane was a stretch and not comfortable for long jobs. I got […]

Vent door friction

I live and fly a lot in So Cal where the summer temps hit 110f, I don’t let the temperature stop me from flying but the Rotax does complain, oil temps will hit 245f on days when the air temp is over 80f in a […]
