I'm not a trainer so unable to help in that regard.
A thought if you are unable to find a trainer in the training arena, go into the main arena (MA) and simply ask if there is a trainer. First use country channel, so the green print. Chances are a trainer will not be on though there are many good sticks (pilots) who will take some time and help you through some issues. They are likely not going to know as much as a trainer but can certainly help you with most questions.
A couple hints. When idiots suggest hitting 'alt-f4' don't do it. It crashes the game and you have to log back on.
Second, pick one plane and get really comfortable in it. Many new pilots change birds like socks, somewhat thinking they are all the same. There are big differences between planes in many, many ways. Switching around will ruin your confidence and any good habits your learning. I suggest a P-51D, which might be the most common. You might be heckled for it but hey, its an awesome bird for a reason. And keep your speed ('E') up!
Best of luck and if you fly Rook ask for some help and I'll see what I can. You'll find great sticks in all three countries.
