Anyone who has built or dealt with a Four Star 40, does this kit have any right-thrust buiilt into the firewall? After mounting my engine, it just looks a little crooked, and I'm not sure if that means I mounted it wrong or it's supposed to be that way.

Yes, it has a bit of right thrust.

Thank you...that makes me feel better. This is my first try at building a kit, so I was afraid I screwed something up.

I've built 3 of them and yes it does thrust built in.... I questioned it on the first one also. LOL

I just checked my plans and it says 0 degree side thrust and 2 degree down thrust.

Odd. The ARF I have has visible right thrust. My first Cor-Star (coroplast Four Star copy) had zero thrust, and I ended up putting washers under the left side of the motor mount because it pulled so hard to the left on takeoff. Zero thrust may be OK for a gutless 60, but I would seriuosly consider adding a degree or 3 if going with anything bigger. Especially if you like short take off rolls. The 4* only needs 15 feet before it's airborne.
