ok, thanks. When your new to a hobby, its hard to tell if a shop is being honest, or just trying to offload its junk.
So far, this one seems to be checking out well.
One more question please, If I want to have a servo to move the rudders, as far as I can see, i will need to have the servo at half way travel, so that the rudders are dead ahead, then it will go left or right on command.
Is that usual? will the servo stay exactly where I set it?
(I did say I was new to this, didnt I?)
