Well yes exactly that. You would turn left on the rudder which is also the primary turn direction. But then use the Aileron to keep the wings at the right angle. Obviously mostly all planes will roll with rudder input. So if you want to keep the rudder in there you will have to compensate a little with opposite aileron. Also keep in mind that keeping the wings absolutely horizontally is not at all the idea. Just a comfortable angle for the model. And well obviously depending on what you are doing. Whether it's catching a low thermal or just plain doing a steep turn.

The thermal thing on AFPD must have helped I got my first spec out with the Electra the other day. A good 40 minute flight (I retired after serious neck strain). And well in actual fact it did spec out, for about 20 seconds we couldn't see or find it. LOL
