Tutorials for CFS3 repaints ?

Does anyone know of any tutorials for repaints specifically for CFS3 ?...If possible, using Photoshop..since thats the programme I've had most experience with. I just want to do something simple to start with. I've done a few textures for other games in the past but aircraft will be a first for me. If anyone can point me in the right direction I'd be mighty grateful.
