I’m ambidextrous. In the school we been forced to write with right hand. In the service all equipment is for right handed. Bulpaps except AUG are horrible)) I learn to row Olympic canoe right handed. In the restaurants I ruined the day of a lot of people by holding knife in the left hand and fork in the right hand. List can go on, most of people don’t even think about lefties, only when they see them write.
I learn to fly CL right handed. It’s a common way in appearance at least. My experience flying combat in early days without safety strap was dramatic. I was able to switch hands during the flight, and in practice we switched models during the flight with opponent, if one model was too slow. Starting engine left handed - I do all my life. It newer work for me to be mechanic in the F2C races. I have a scar on the left forearm from running prop. I started engine on the combat model, holding engine mount by right hand, switched hands, and stepped over lines. I do that if no helper around to hold the model. In the time of stepping over the lines the heel of my shoe caught the line, and prop bit my arm.
My opinion on the training of grandchildren - do anything to make them happy and encourage them to fly. But don’t build clockwise models. The granddaughter may like to be one of the famous CL girls, and will participate in the competition, with rules for counterclockwise models.
