Retrieved the nose wheel spat from the ceiling storage. The two went together very well. I have drilled 3.2 mm holes at the moment. The manual calls for 4mm rivnuts to be used, not quite sure why, I'm sure 3 mm rivnuts would be OK. I will have a think about that over the next couple of days. Back to work tomorrow, I have got alot of building done in the past 3-4 weeks, our jobs really do get in the way.
