RE: Byron Wedell Williams Racer Build
Mine is set up like the pictures in the build manual. In fact it is the one of the planes that was constructed to make this manual. However there is nothing wrong with putting the rudder servo in the middle.
Remember also that the servo cases were larger when this was first built in the mid 90s. the maint thing is to get the controls where they don't rub or bind. The fuselage is long enough that the rudder servo can be set to one side if needed with no adverse affect on this particular airplane. The tailwheel springs are a bit weak. It wouldn't hurt to take one to your local hardware store and see if you can find something about twice as stiff. Dont worry about feed back to the servo as about any late model servo that you choose will have more than enough gear train strength.
