Have fitted the two fins (Keels) today, one being made up of three layers of balsa and shaped to profile, and the other from a broken model helicopter blade, scrounged from a friend.
Helicopter blades have exactly the right profile for a fin and rudder - if you have a friend who flies RC helicopters, they will have a broken blade or two lying around - trust me!
Once again they were tacked in place with cyno and then when secure, set in place with epoxy.
Both rudders have been cut out and the intention is to again, layer them up from three pieces of balsa, but to set the pivot into the middle of the lay-up. This will be done in conjunction with setting up the rudder pivot tube to get the correct height and placement to enable the servos to be mounted in the hull.
Hi David any chance of going into more detail of your keel...I'm looking for dimensions etc in depth if possible. I'm building my first footy boat but the plans I have do not include a keel or rudder. Thanks Simon
