Next - the rudder.
A piece of scrap balsa was drilled through to take the rudder tube then epoxied in place. The rudder shaft was made from a scrap length of stainless steel welding rod and the blade made from 3 bits of off-cut plasticard. The inner core was secured first by cutting out a vertical section to accept the shaft and epoxied in place. When this had cured the other 2 pieces were glued on and the whole trimmed to final shape.
This is a fairly large rudder to catch the wash from the props when turning. (Hope this works in practice).
For the tiller assembly I used a washer, a 3 pin plug pin (cut away to leave just the head c/w screw) and a piece of flat brass bar, suitably drilled for attaching the tiller rods and a centre hole to fit on the rudder shaft - these were then soldered together.
The rudder servo was then screwed into place, tiller rods made up and fitted then tested by hand- it works!
Now the whole assembly was removed, a hole cut through the bulkhead for the servo cable, the rudder shaft cut to final size and then, with the shaft suitably greased, the whole assembly was refitted and tested with the r/c gear - works a treat...
...so here's a few more photos to hopefully maintain the interest.
Aye,
Ray.
