Maybe this thread needs to be locked away for another 10 years, by which time we'll all be flying sub 4.5kg, contra drive, electric, composite tri-planes and we can all look back and have a good laugh at the 5Kg rules that USED to be so important but just isn't an issue anymore

Hopefully by then I'll have the new Futaba Faasssteestesst 4.8Ghz system with 42V servo's (or will we be arguing over 10S vs 12S by then?) running some Ice-cream Sandwich OS (or whatever dopey name they can think of) instead of Windows CE...
