For linkages I am going to do just as the manual says: two pieces of wire joined by heatshrink, with z-bends at each end.
I put the Extreme tape under the wing tape. The manual said to do the same but to just use wing tape (4 layers). I used 3 layers of Extreme - I think that will be enough.
The reason for the heat gun is again, just because Doug suggests this (as an option) in the manual. Being a clueless newbie I didn't even think of an iron. Can an iron be used on wing tape?
