FTL (Fixed Tail Long): The FTL has a longer pedestal, making the distance between your front and tail foils longer, essentially lengthening your fuselage. The FTLs are more stable with pitch control that stabilizes your up and down movement.
These are Solid Carbon Fiber tail wings. Built of High Modulus Prepreg Carbon under high pressure and heat in an Autoclave. This technique gives maximum strength and bonding of the Carbon Fiber.
