Covering of the Canard and central fairing was fairly straightforward, but I agonised for some time over the attachment of the winglets. In the end, I fixed them with double sided tape and a carbon pin at the trailing edge. The outer face of the winglet was covered after it was attached.
The winglets are easily snagged, so it will be interesting to see how long it is before they get knocked off.
Of course the same applies, only more so, to the tip fins on the main wing, but that's a dilemma for another day.
