Jeff,

They must have sent me the LX version by mistake; even the pushrods are austenitic stainless steel.

BTW - For Jack and others, here's some more photos of the wing assembly fitup pieces...

After very light sanding to remove factory surface glue, still measures about 2.0mm thick with my caliper's depth gage.



fitup with carbon rod (same outside diameter as aluminum pipe)



fitup showing fitment with factory bevel edges



again, fitup from other side, similar factory bevel edges

then together. You can see the foam step up where they meet



again, leading edge. Foam steps down where they meet.



fuselage opening, looking rearward, no steps in foam



another view looking forward, again no steps in foam.



A solution might be to replace the 2mm thick plywood with 1mm carbon sheet or 1/32" (0.79mm) thick plywood. The carbon would remove 2mm of step from where the foam meets up. Removing the factory plywood without damaging the foam could be a chore, and cutting carbon is pretty messy. You'd also need a 10mm hole cutter (pins measure 9.78mm diameter). Sheet carbon available from many sources, including HK...
