It worked, but the engine wanted to pivot on the bottom rear supports. Sat heavy on the bottom front ones, and pulled hard on the top rear ones. (Yes. I had six attach points.)
With what you have, I foresee the yellow members being in extreme tension. Not a problem as long as you anticipate and plan for it.

Ernest - forgive me if I am not following but it sounds like you are saying the mount did not work for you?
Looks a lot like what I did for the Dyke Delta I built if you leave off the yellow tube on both sides. The nose wanted to droop down. I even had two more triangle that attached to the top rear corners of the engine with adapters that I built. The engine pivoted on the bottom rear supports. The bottom front pushed up, and the top rear pulled back.
Well I think I have designed my mount for the Glasair. Overall I think it will be a bit overkill but I am ok with that.
Should put the CG close to the same spot as for the Lyco. Thrust point in the same spot. Green bars were part of the Glasair mount for a Lycoming. (There was also one between the two upper points but I don’t think any of them are truly necessary with the stabilization of the plate. Yellow bar I am calling optional at this point to make it easier to work with intake/exhaust. Another idea we had was to weld on a flange for both sides of the yellow bar and have it bolt on during final install.
Thoughts?
