RE: 1/2A society
Well, obviously 'true 1/2A' means a displacement between .020 and .050. That's why I suggested I.M.E.S. - it avoids the whole class and competition limitation. Personally, I think it would be a good thing to avoid a serious class system, and avoid serious class-based competition. Something along the lines of the reedie races and suchlike would be fine, but the actual class competition is already covered pretty well in other groups such as SAM and so forth. I think it'd be better to focus more on the sport end of our hobby. I think it might be a good idea to use the IMAA as a model to work off of. You know, 15 years ago or so about all that was available for giant-scale (in the powerplant department, anyway) were essentially modified weedwhacker and chainsaw engines. Look what IMAA has done for giant-scale, why can't our organisation to something similar for .000-.090 size planes?
