Well, I was an (amateur) drummer - a drum kit is operated with both hands and both feet, all doing different things.
So I hope, that won't be too much a problem. It's only the forgetting about the twisting of the stick, that may be difficult.
That is pretty barmy indeed, and so I understand it very well. But remember, the German pilots were usually very well
trained in big Fliegerschulen (like Müncheberg, southwest of Berlin; or Döberitz, west of Berlin); so they would know
how to land their kites, I guess. See the pics here, if you are interested in Fliegerschulen:
