RE: A4 Skyhawk build
Having now done the rudder it actually works rather well which has taken me by surprise as the other models I've built using this method have been less than satisfactory. The only slop in the rudder is that of the gear train on the 8411. Still need to see what its holding power is like but feels promising.
The steering uses two cylinders on either end of the system the servo moves one and the other moves proportionally to it, have a look at post two and you'll see what I mean.
