I have Futaba 3151 on ailerons and elevators, and 3152 on rudder, 3001 on throttle. I find the original horns and pushrods quite OK, except for the rudder. I have upgraded the rudder horn to a much more rigid horn, and the pushrod is a 6mm carbon tube with ball links. I also use Sullivan .60 - .90 size tail wheel assembly, the original steel wire broke quite soon (actually, Iäm on my second Sullivan tail wheel bracket already).
