All of this brings to mind what the REAL problem is when landing a plane on a short strip. Yes, you can use flaperons (full length strip ailerons drooped for landing) or separate flaps/aileron with and preferably if your radio is a computer version then mix in some crow (where ailerons deflect up when flaps are downlike a crows-wing/tip feathers upon landing)...or....yes....OR learn to always fly the rudder as well, 100% of the time (yeah man, that left stick is very useful in more than just knifedge)

What I am driving at is I feel that if a person learned to fly "properly" then he will have flow at least one trainer early on that was 3 channel(rudder elev throttle) and if he took advantage of a small often overlooked segment of learning between the Rudder turned plane and the aileron turned plane, he could easily train both thumbs to track a turn simultaniously. As one progresses to more advanced manuevers, both thumbs are already moving to steer the plane and it is not hard task to just start thinking of what you want to do with the left thumb and not have to think what you are doing with the right one.. The "slip" is then nearly automatic and as full scale pilots have found since the beginning of time that that is the safest, cheapest, coolest and most controllable way to "slow er down" for short strips. Doesn't matter what/whose plane your flying then, it is easily done.

There is one observation about the slip manuever. Since I do those automatically (balancing the correct aileron amount with the correct rudder amount), my only thought is to automatically add just a bit of down elevator to counteract the ballooning effect the dihedral creates as one wing comes forward. No dihedral pretty much equals no ballooning effect but be ready for the sudden drop in speed which will tend to drop the nose a bit.

The above example is complicated by which mode/ transmitter setup you learn to fly on.To really take advantage of this system requires your first Rudder-elev-throttle trainer to have the rudder on the left stick with he throttle and the elevator on the right. When you "pick up" ailerons, you will automatically be using your right thumb and not have to reteach your right thumb to fly ailerons instead of rudder.

More advantages to this method is that you really don't have to concern yourself with engine right thrust as you can automatically think of adding the correct amount of right rudder stick to offset the torque.

Its a bit more elaborate to learn to fly this way and is kinda like flying helis with no heli radio nor gyro (which I have done as well but is a LOT harder) but you learn how to REALLY fly a plane and all the computer does is make you lazy. Crow though , is pretty much ENTIRELY a computer option.
