Well I just did an order with Tower, bit of a top-up of parts actually and are using http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFV43 with one for the rudder and two for the elevator, but will be jointing the two elevator rods at the servo end with this here http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFV37 I think as long as they run up each side and come together parrallel it should be ok, KISS "keep it simple stupid" its alot better than mucking around with bearings like my old design
