Hermann Andresen sent me a design for a Limited PP prop...I wasn't
building a LPP at the moment. So I put it on the A-6 (more or
less) ... not that this makes any particular sense! I can't see how
blade shape will accomplish much on an A-6 prop where the wood is so
thick that you aren't likely to get any flare.
Hermann's prop design is based on the idea that the trailing edge
should be straight, and the tip and hub should be straight or square
too, not rounded or tapered as we usually do. I have concerns about
the "straight" or square hub from the point of view of getting the
steering line locked into that area.
There isn't anything exotic about the A-6. It came about because
Mark was involved with the rules clarification for A-6 and I was
curious about the class. I find it difficult to have much insight
into model classes I haven't actually built.
