Hi,Buka.
Set your c/g at 25% of the mac, this is the most important step ,,do not use a 35% cg this is way too far back on all pattern models regardless of the design.
If your wings are 900-950 sq. and the airframe is over 10.5 pounds you will need .7-.8 pos inc.
set the stabs at zero But you will wind up .2 or so pos, if they are adjustable fly first and adjust the stabs to the elevator trim ,,,after you get the airplane
flying pure.
The airplane only needs .5 down and .5 right thrust but this is not important right now,
the only reason why you would need rudder mix ,,,,is because the airplane is tail heavy regardless of what anyone told you.
With rudder mix,you are compensating for an unstable aircarft. try to shoot a arrow with no tip ,,,I don`t care how big the fletch is it`s unstable and it wont go straight.

Guys,these are not theorys they are proven by 20 years and about 15 designs,,,, prove me wrong if you can <G>
Do you want a 5 % overall improvement in your Score? ,,,,try my Method.
also How Could I predict Niko`s trim problem in my article ,,,if I can`t give you the Cure
and by all means follow to the letter of the article ,,and let us know what happened
I have helped countless guys trim their Integrals with no, or very little Mix.
set your c/g to 25 % first...very important.
then use my method.
Here is some home work for you guys,,,
Go to Oxia `s web site, look at Christophe`s new design on the side view, he also uses the same setup I use ,,,,now
tell me if his wing is not set up at about .8 pos,,,
then admire his snaps again
