The M2 size bolt slips perfectly into the hole on the Saito needle valve. All that's needed is to file a flat spot and put some locktite on the set-screw. I've ordered some M2 x 6mm socket head screws from Micro-fasteners. An M3 bolt filed down also works nicely. I can't believe I haven't done this before!


And, yes, the idea of running a linkage rod to the cockpit is REALLY REALLY cool!
