Evening, Afternoon or Morning together (depending on where you are at in the world),

after spending several months of thinking of a new hobby, I have finally arrived at fixed-wing RC planes.

Well, I already found out that this can be a very expensive hobby, if you dont take your time to learn it.

Basically, I found an RC Plane Club nearby, which I plan to visit and check out before starting (and if only to get a reconfirmation and to know what guys im gonna have to deal with).

I do have a grasp of basic aerodynamics, but not to the point that I could actually build a plane and hope that it flies (I might get the wings right-side up but on the wrong sides...)

I plan - if I can get my hand on one - to buy a used training plane. What I would like to know is what I should watch out for. Like what kind of plane should a total beginner use, etc.
I will also try to get some instructor training, but I think that I cannot really fly someone elses plane and then crash it. It would not feel ok to me, even if the owner would be fine with it.

So: How do I get started (beside finding a club to join)?

Cheers
Sid
