The wing root fairings were a little strange in that you need to countersink the forward holes on the upper wing root spar in order to accept the dimples of the upper wing root fairing. It's a little difficult to do with the wings in the plane for the most inboard hole. Would have been better to do this before mounting the wings. However, once I got my right angle drill out and carefully countersunk each hole everything came together perfectly. There also was a small gap in between the fairing and the fuselage at the front but not really anything between the rest. I'm not sure how to address this but I'm dining many people with the same issue and they are using various solutions. Some sort of seal material would be nice but I can't seem to see an easy way to install any of the options out there. I'll postpone this for the moment. This was only short lived as I still need to complete my rigging and also need to connect my fuel system. I have decided to go with the wing root fuel filters which will be a deviation from the plans and will also require me to remove the fuel filter from inside the tunnel of the plane. It is assumed this will save me time in the long run….let's hope so. These mods are not cheap! The rigging was incredibly satisfying. Although I did not enjoy working through the access hole to remove and replace the bolts holing the bell tanks together, I did manage to get good at it with the right combination of universal head and extensions on my socket wrench. This allowed me to adjust every little detail until I was able to get both sides perfect in trail at the same time (with flaps fully retracted). The “trail” position of the flaps is -3 degrees and so when you combine that with the ailerons you end up with a slight mismatch of the ailerons and the wing tip. This is normal although it appears wrong. There is no way you could have both the ailerons and the flaps line up with the wing tips so apparently this is just the way it has been designed. At any rate, mine lined up perfectly together, so hopefully it flies like a dream.
