| [quote=wonwinglo]*** Well spotted Malcolm,the outlines are made from either thick card or in this case balsa,three to four strips of 1=32nd by three sixteenth balsa strips are wound wet and left pinned overnight,the next day they are unpinned and then glued together,left to dry again and sanded,result one very strong and light wingtip,having used this on models from a few feet to several feet I can testify the bouncability !

I modified the rudder construction of the Tiger Moth I am building in this sort of way.
The plan shows a sheet rudder. I made a template from ply and formed four laminations of 3/16 x 1/16 balsa glued with PVA and taped to the ply using masking tape to make the rudder outline - it was a bit tricky to get the curve round the top.
When this was dry I built up the rudder with scale position "ribs" and the reinforcing members and covered the final assembly with Solartex.
The leading edge of the tailplane was made in the same manner - this was detailed on the plan and prompted me to try the technique - often used for lightweight wing tips on free flight models years ago - for the rudder.
For my money this produced a lighter, stronger unit with a more scale like appearance. I was very pleased with the result, which so far has stayed warp free.
