With a nose wheel equipped KR it is quite easy to setup safe single person operation with a hand propped VW.
I carry a chock with a rope that can reach the cockpit, I can then start the plane, walk around and get into the plane and get comfortable. Once ready I simply "reel in the chock" and I am ready to go. The chock can be seen "deployed" in the photo in the link below. http://www.rudix.site/zu-cgr/Photos/rv7_5708_std.jpg Fly safe, Rudi
