RE: SPA Rules question- Why aren't retracts allowed?
Regarding Aerobatics - we have an AMA Pattern SIG, a Scale Aerobatics SIG, and a Senior Pattern SIG. We also have FAI. There are many factions, which are basically distinct and separate from each other. Can they be or should they be united? Is it easier to try to unite them or create another division with another flavor for 70-80s pattern planes? I don't know.
I do know that the real question is this.... "should we create a class and see if folks will come, or do we try the idea by flying some 'demo' competitions to see if there are enough participants to support it". I favor the latter. If you feel there is enough support for a Piped .60, retract class, develop a contest schedule and see if folks participate.
The way things happen is that someone has to make them happen. I don't think you can ask a special interest group to expand their special interest to include yours. You have to do it for yourself and the others who feel the same way you do.
I fall into the same category as Raineday. I am building what I like and not necessarily for competition. May compete in SPA, may not, just enjoying how the older planes fly now.
