After having the 'floating spring' steering idea i then had to think of a way of transfering this steering input into the wing
As the wing frame is only made of 5mm fiberglass and wanting to stick with this for its great balance of light weight, flexibilty and strength, it also had the drawback of not being very good in torsion.
I needed to make a wing steering design that transfered all the energy from the servos through the wing else it would just twist the keel and do nothing
The best way i found to do this was using a 6mm aluminum sleeve over the keel and attach everything to that due to aluminium being alot better in torsion and also being stronger for the hang bracket point and the bearing to ride on.
The clamping kingpost/'a frame' mount is also mounted to this alloy sleeve, aswell as the bracket the servo arms come up to,
This means all the energy goes from the servos, up the arms, pushes off the steering arm plate and tranfers that force through the aluminium sleeve and down the 'a-frame' to the corners when its can pull the flying wires which are mounted halfway up the leading edge of the wing,
This offers a big increase in leverage and better steering.
On the early version i had a problem with the steering plate bracket slipping slightly on the alumimium sleeve and putting the trim out, to solve this i ran a cable down to each corner of the 'A frame' to hold it in position,
This is now a really proven and solid design which i am pretty proud of :)
Ill post some better pics to explain this when i get some
