My up elevator position in cruise is the same as Als too.

Barry;
I think Im beginning to understand a little better. I recall now also
having that issue, and I added a wedge shaped shim between the spring and
metal bracket that fastens to the torque tube; thus rotating the torque tube
and giving more up elevator travel. IIRC, the top of the shim is ¼+ and
maybe 1/8 at the bottom. Sounds like you are already doing that maybe a
bit thicker shim will help, or perhaps changing the mounting of trim
actuator.
How much trailing up on the elevator when you are at high speed? Mine is
typically about ½ to ¾ single pilot, and a bit less with a front seat
passenger.

Hello
I get full movement up and down on the ground. In flight I can't get enough
up travel. I did use a shim between spring and elevator tube to get a
little more movement ( advice from velocity) but I still can't get enough
nose down at higher speeds. I made my own canard and elevator as spec.

Elevator spring strength. Can you put more ply's on the spring to help with
trimming the nose down. If so how many ply's? Would that be uni, bid. Would
the plys be on the inside or outside of the springs?
Thanks
Barry
