That's interesting. Finding the originator of the idea (and when) is worth a little research if anyone is so inclined. I can only add that the technique was on the original Top-Flite Gieseke Nobler plans.
I do know we (me or anyone I flew with) had never heard of the technique back in the mid-60s -- which doesn't mean the technique was discovered after that. But it was not widely known then, for sure.
Well, I don't think it is widely known today, otherwise you wouldn't have posted it.
