Welcome to RC Aircraft.

I think you may want to choose a different aircraft to learn with. Keep that plane for the future, but I would follow the suggestion above and get a good high-wing aircraft that has been rated as a trainer.. slow and forgiving. Get one with four channels, throttle, elevator, rudder, and ailerons.

Forget all the gizmo's (flaps, slats, and all the other stuff) until you get flying the trainer as a trainer and can sucessfully fly it, and land it, without crashing. Fly it high (we call it three mistakes high).

Since you already do RC Cars, you know the right-left thing (orientation changes as the plane is coming toward you from what it was going away - all turns are with reference to the aircraft and not to you).

By their nature, warbirds are difficult to handle and are not really good trainers.
