Radcom,

I am suggesting to always use Bi-Di. On the Battle Axe we fully cover the wing in Bi-Di. I don't know how the "floyd" usually does it, but if I were you I would fully cover the wing in Bi-Di, and then use the colored tape or econokote.

The Bi-Di tape is what gives the wing it's strength. The colored tape or econokote gives little strength compared to the Bi-Di, it's just for cosmetics and streamlining..
