Having pre shaped the shrouds that also act as a guide for the lower wing pegs I braved up ! and drilled the spar to fit them last night. Careful drilling – don’t want to mess the spar up. Also, you have to be careful as to where the rivet will go, there are large doubler brackets inside the spar that you need to miss !
When done and during fitting .. make sure you can ‘twizzle’ the connecting rod ie it runs freely
