In fact Mikado links work out well enough, not sure if the geometry will work out, must get the head built to see.
Have balls out 11mm from centre, that translates to plus/minus 16mm (Total 32mm) on the elevator crank before any binding. It does bind slightly just before the servo maximum throw, the servo horn hub comes into play but should be good with these if I have enough movement on the crank, fingers crossed.
Post edit, the swash needs a mere 7mm of movement for 13 degrees of pitch on the main shaft, plus cyclic in worse case, looking good for throw.
