I began tackling the various fiberglass tips this evening, by marking and cutting the notches in the vertical stabilizer tip to accomodate the VOR antenna "puck." This will eventually be where the cat's-whisker VOR antenna elements will be attached.
I know, a lot of people install them underneath the aft part of the fuselage, and if I had a time machine, that's probably where I'd try to put it, too. However, in the old RV-8 kits (like mine), that location is a lot harder to use because the aft fuselage has VERY limited space into which to insert one's body. And therefore, in 2003 I installed that VOR puck in the top of the vertical stabilizer -- and by golly, that's where it's staying.
The only bad part about this location is that the antenna elements become eye-pokers. I will probably have to remove them when the plane is on display, just for the safety of spectators.
