I am having a bit of a problem trying to set the right height for my Jetcat thrust tube. the engine (JetCat) is mounted on the engine rails. I am not using any packing.

The Carbon turbine deflector guard which mounts to the bellmouth and its mounting ears sit between the engine mount and engine rails is keeping the thrust tube sitting to high.

I cannot lower the thrust tube( airplane inverted) because of the turbine deflector guard. I do not want to add packing to raise the engine on the engine rails.

Is the deflector guard really necessary?

What have some of you done to solve this problem?

Thanks,

Stan
