Hi All,
Sorry for thsi post, but I'm stuck !
I've got a trainer with a MDS MDS40 Pro Aero engine in it.
I can see where the server rod is connected, but it will not open the air hole, it look like its stuck. Its a new engine. What I need help in explaining what each screw does to the engine (A B C & D on the photo). If got my first lesson on the weekend, so it will help me learn if I know what they are talking about.
A is where the servo rod is attached to the link. The "hole" (sorry, don't know what its called) between B & C will not open like it should ?
Is one of the screws locking the engine?
Thank for your help,
Pierre
