The rear planes seem to have been giving me grief lately. I have not had much time to work on them recently, but for such a simple task there proving to be a pain.
The rudder fins are screwed to the upper and lower hull. They say in the instruction that if you glue them on they can become dislodged easily or broke. Seems a bit odd, that most other boats have them glued but there you go.
After the holes have been drilled carefully, you can insert the screw from the inside out into the fins. And screw them up by drilling another hole in the bottom and top of the opposing side of the hull, where the screwdriver is inserted. But if theres any defoprmation in the inner coating of the GRP hull like mine, the screw wont sit flat, and therefore the fins are wonkey
So after more grinding with the Dremmel and cutting threads in the fins for the screws they are on at last. Both rudders work off different shafts, so a coupling device is made up of a small sheet of brass, 2 pins and 2 couplers with grub screw tightened collets. If you have small hands you are laughing. If not ( like me ) its awkward.
The planes are fitted a sililar way, just modified mine to use a brass tube as a bearing which goes into the fin and the hull, with the solid brass rod going through the centre, and glued into the fin.
Works pretty well.
