Bill, did you ever get a reply to your post. the cushcraft traps are fairly straightforward on what goes where!! The traps withthe taper on one end go on the outside and the traps with the same size ends goe to the inside with the end with th screw terminal under the black cap on the boom side. Below is the turns cheat sheet for their traps!

Cushcraft p/n designator
TA...............................10m trap has 18 turns
TB...............................15m trap has 31 turns
TC...............................15m trap has 31 turns

TA traps go on the inside (boom side) on all three elements.
TB traps go on the outside on the front (director) element.
TC traps go on the outside on the driven and reflector elements.

Good luck with your project if you are still doing it!!!
