The plans for the 4 Star show the old mounts that the kit use to come with not the new glass filled ones. Where do I mount the engine mounts on the firewall in relation to the thurst line on the plans. Is the thrust line suppose to line up with the top of the mount rails?

I am just getting back into R/C this is the first kit I have built in many years. Below are some photos of the wing.

Yes, the top of the mounting rails are on center with the thrust line.

I built the 4 star but dont have the plans anymore (or the plane )  .  Doesn't the thrust line normally  run  through the center of the prop or is this different from design to desing with some above... some below.. and some in the middle (though the prop).

on my engines the bottolm surface of the mounts are in alignment with the c/l of prop.

The center of the crankshaft should line up with a centerline designated on the plans. There should be some type of marks on the firewall (lines or dots?) that indicate where the thrustline is. When in doubt, refer to the plans.
