im mounting a os.61 engine in a alpha 60 after i measured, drilled and installed the engine when your standing in front of the plane looking back at the tail the engine is setting slightly to the right not much but you can see a slightly larger gap between the engine mount holes and the outside of the mount on the left side will this matter enough to have to do it over? man i hope not i sure thought i had it lined up perfect!!

Most planes require right and down thrust. If looking at the front of the plane FROM THE REAR, the prop shaft should be pointing to the right and down. If it does, it's probably ok. Now, right and down.. only a small amount..a few degrees only. Not severely.

Sounds like he means it's off center, which shouldn't hurt anything.

Joco, don't sweat it.

didnt think it would matter but just wanted to be sure! i sure thought i had everything lined up perfect, checked it several times and then drilled it and it came out like that! kinda frustrating when you think you have done everything right!!!
