Thanks for the tips guys, by the way Oipigface the Fighteraces website is blocked on my pc as it's a 'dangerous website' and hence black listed!

The object of the exercise is to wet out the cloth with the minimum amount of resin for maximum strength and minimum weight. Applying the resin to the wood first allows the balsa to soak up the resin and once the resin is into the grain the credit card will not get any excess out. Laying the the cloth over the wood first and applying the resin through the cloth allows you to apply just enough resin to wet out the cloth. I then lay kitchen roll over the the wetted out cloth to absorb any excess resin. I use the foam rollers to apply the resin as with a lightly loaded roller you have to work it into the cloth until the the cloth has absorbed enough resin to go translucent rather than just daubing it on with a paintbrush. Doing it this way around requires considerably less resin which equals more strength and less weight. Works for me.

Hi guys, here's the port wing of the LF-107 Lunak, from rib R8 to the tip 6mm washout is built into the aileron. If I do it this way then I would make the tip sweep up on the trailing edge to match the aileron. I was suggesting making the whole wing with a slight twist to allieviate the wing tip 'sweep'. By twisting the building board the wing and aileron could be built 'flat'. Perhaps I should just go for option A and jig the aileron?
