The Futures TMF 2 (The Middle Finger) Trailer Fin is a 5th center fin that can be added to any quad set-up. By reducing the area of the TMF 1 the TMF 2 allows for more release. The fin will increase drive and provide directional control through turns. The perfect addition for any high performance quad. The upright template of the TMF-2 allows the fin to pivot more freely without sacrificing speed, flow, or the freedom of movement typically associated with a four fin set up.
