After cooking breakfast for everyone on Mothers day, I started work on the vertical stab. fairing. This is a job I was not looking forward too, however, once I had a plan of attack it wasn't too bad. I was going to use 4mm rivnuts but decided to go with 3mm as instructed in the Sling4 and TSI build manual. I have four more rivnuts to install after I remove the fairing, then I can put the rudder, vertical stab, horizontal stab. and elevator into storage.
