Does anyone know if down thrust is required. The kit plans do not mention any and there appears to be no offsets with the firewall? I add right thrust as a matter of practice however, if it is not built in to the firewall.
Thanks for your help.

Right thrust only on mine and it flies great.

I added a bit more right thrust with washers. Now the vertical is good and straight. I have a Saito 100 in mine.

I have a supertiger 91 on my FourStar 60 and it the best motor for the plane .It make it fun to fly!!!!!!!!!!!!!!!!!!!!!!! What motor are you going to use

I'm using a O.S. 91 Surpass 4S with pump. Plane flys very well.
Good kit overall.

I built a 4*40 a few years ago and added @ 2 degrees of down thrust. The airplane flew like C#!*! It required a large amount of up elevator trim to even get it to take off. It would not roll, and, naturally, would not fly inverted.
