Only removing plywood packing, I will mount the turbine on the rails and try. So yes, raise the front of the tube around 6mm from where I am.
My very early kit the elevator servo plate is lower than later kits and restricted height option, hence the packing plywood.
If you place a straight edge across the wing seat, my purple Jetcat 120 cover is flush now and will be 6mm higher after the change.

Dave
