Hi Everyone; 



I'm taking a long hard look at the CH750, but am wondering if the aileron flutter mitigation is also performed using control line tension or uses mass-balancing too.



Does anyone know if flutter analysis was performed on this design?

I will chime in here.. First I have an 801 but I assume the whole 701-750-801 line has mechanical linkage between the stick and flaperons.. Also the 801 has split flaps/ailerons, That in itself "preloads" the entire flaperon and should stabilize it to prevent flutter. You 701-750 guys can add to this if I am off base.. 

do not archive

Gents! Flutter prevention and mitigation is part of any designed aircraft.   The subject line is valid!



Given the recent hubbub (real word?) and my interest in the design of my candidate aircraft list, I was curious as to how it is approached in the CH750. 



For example, in my research, I've found that the Kitfox uses a mass-balance approach for ailerons in combination with mechanical pushrods.



I suppose that given the limited activity of 801/701/750 owners on this list, it's a question I will have to phrase delicately to Zenith and see with my own eyes next chance I get.



I really wish I could get to Florida for some sun n' fun!  I guess we'll have to give it a look-see at Osh.
