I have read the manual back and forth and I can understand the single custom mix. But what I would like to know is is it possible to mix more than one channel????

What I want to do is create a 20% - 25% mix from the cyclic to the throttle. So far Have been able to either mix the aileron channel or the elevator channel into the throttle channel but not both.

What am I trying to achieve here? Well I dunno if this happens to any of you guys but while Im hovering the heli will lose headspeed and some altitude with some cyclic inputs (I think this is what they call pogo effect?). So I got to thinking if I mix a bit of throttle into the cyclic this should minimize this????
