The Futures Fins TMF-1 (The Middle Finger) Thermotech Specialty Trailer Fin is a wide-based trailer fin for use as a 5th fin option, adding just a little more control to your favorite quad. Made in Huntington Beach, the Thermotech product line does not have the traditional plastic feel of a composite fin. Instead, they have a consistent flex that creates drive and release through turns.
