Well, I just added the "and" as per your instruction. When it didn't work, I deleted the whole Auto-trim section. This worked trim-wise, however, the whole steering (front wheel, rudder, ailerons) was out of order.
Therefore my question, if there was a way to delete the Auto-trim while keeping all the other goodies.

PS: Maybe this has nothing to do with the problem: After start-up, I have to push Ctrl E in order for the GPS to work. (electrical state?)  :-[
