I have some RC-friends who are airline pilots, and they had to learn to fly model-airplanes like anyone else The difference is quite big.

When you sit in your 767 everything is the right way and you have a lot of training, but when you take off with a model the hard thing to learn is orientation. In addition things happend so much faster, difference between headwind and tailwind is noticeable and windghusts really do affect the plane. And as soon as you get used to all different orientations you still have to know a model stalls. I remember when one of my airliner-friends did maiden his Chipmunk I told him on the downwind leg that he were about to stall. "No" he replied, "I have enough flyingspeed"... and then he tipstalled and crashed. I told him how important it is to know winddirection and not just look at groundspeed as the parameter.

But you already have gained some experience, and I know you will like this hobby. Just do as already mentioned; get a foregiving trainer and get a lot of flying time. Then you could build a nice low-wing plane which you really like, but use the trainer for a while and get used to models before you maiden a Mustang or Mig. When you are used to flying against yourself without problems and launch a scaleplane always make sure you have enough flyingspeed. Especially when you don`t have the height to recover. The first stalls and other dangerous manouvres have to be tried at good height to get used to what happend.

I know the Minimag is a good, rather small but strong trainer. When the wind is calm just use the dualrates and you have a smooth model. Not the nicest thing on the ground, but when airborne it will give you what you need.
