I agree the parts are simple to cut, I did all the parts in one Evening.
The wing ribs a snip, as Peter said cut a ply template and it's easy. I then did Peters other trick clamped them together and sanded to final shape.
This is only my second build and it will take me about another two weeks to complete. I entered a Year ago at the deep end with a TN Lysander 300 hours later it's finished and I am really chuffed...Having got my A cert in three months!
