I have did the mixing a number of ways using flight modes

try it with an w/o the mix for your 3d and see if u needed or do not need it. I also fly the EF Yak and it required so little of mixing on ailerons about a 2 if I recall correctly. A 2 is not high enough to effect that deal. I have an BG 30% ultimate that in one direction it requires more elevator than the other and the ailerons mix is a 7 so those ailerons are moving a bit more than the 2 pervious mentioned.
