Bill,
Do you think John Barker (the US version) could have been misremembering the AMA rule: ‘Horizontal stabilizing surfaces in excess of 50% of the supporting surface (the wing area) shall be considered as wing area’?
John Barker (the English version).

I agree that the larger surface should be considered the wing. I would think that the larger surface would be measured by area not span. Mini stick has a maximum stab area rule. How can I find out how this would officially be interpreted before I put knife to wood?

I once overheard John Barker (the USA version) speaking of this. His contention was that the larger surface should be considered the wing.
I'm not endorsing or rejecting this - just repeating what I heard. I think if this is the "intention" of the rules then a rule change clarifying that all surfaces must be 18" span maximum would be a good thing. Maybe a similar rule for ministick as should also be introduced.

A few days ago Vladimir Linardic mentioned his OPP was ruled out at USIC. It seemed like it was due to 24" stab span, but maybe it was due to something else. I can't see where a 24" stab would be against the rules. I ask because I was thinking about building an OPP and have considered a large span stab. I know that people fly ministicks with large span stabs because the rules are silent about this. Isn't it the same for OPP?
Thanks,
Rey
