well, because there's a mixer, if the blade is at a positive angle, the leading edge will have the tendency to go downward due to the wind pressure on the trailing edge. so right now after the change, if the leading edge trys to go downward, it'll pull on the head and push on the swash because there's a mixer. and if it's negative pitch it's the other way round...

so the force exerted upright in this new configuration is basically the same as the force exerted inverted in the stock configuration? oh well, i might still need mabye a few days to try this out. where can i find the info on this though? where did you get the pics and infos?
