i've had my sukhoi for a few months and overall am very happy with it. the only "issue" i have is more pitch coupling than i'd like when i'm on the rudder (especially at extreme deflection). with small rudder movement, i have to mix in about 8-10% of up elevator to prevent it from pitching to the belly. but at extreme defelctions (like when doing a hammer-head turn, it pitches really badly to the belly, and the 10% mixing is no where near enough to get it straight. i also like to do "knife-edge harriers", which require 100% rudder and it's very hard to do on this plane b/c it pitches so badly to the belly.

anyone have this problem and/ or suggestions on how to correct it (other than using radio mixing). is there something i can physically change on the plane to compensate for this coupling?

one other thing is noticed is that i cant get it to roll quite as fast as i'd like. on high rates, it rolls just as fast as low rates, which is about 70% of high rates. in other words, there is a limit to how much aileron deflection i have and how fast it will roll. right now 30 degrees on the alerons is about as much as i can go to increase the roll rate. (when i increase the travel to 45%, it does not make it roll faster). i'm thinking about putting on some home made "side force generators" on the tips of the wings to "trap" in the air flowing ove rthe wings and maybe this will help make the ailerons more effective??

any comments/ suggestions?
