AC2,
The tail wheel servo has to both raise and lower the retract assembly and open/close the doors . The retract mechanism its self is a bit sloppy as far as side-to-side play with all the parts and pieces, but built sturdy (looking). I found the linkage geometry for the tailwheel doors a bit time consuming to figure out because the linkage is not a straight up/down action. Due to the length and travel of the retract bracket (and the lesser travel of the tail wheel doors) the linkage has to swivel. You will see this when you hook-up the tail wheel assembly to the doors on your mustang.
You very well may find (I hope) a slick way to hook up the linkage and make the tailwheel retract and gear doors work with the micro servo. If you do please share your ideas (with pics) so I can see what I'm doing wrong with my plane.
Thanks bud,
Sonny
