The flutter characteristics of a folding control fin with freeplay are investigated by the flutter wind tunnel test. Based on the characteristics of the structures, the fins with different freeplay angles are designed. At the situation of 0° angle of attack (AOA), the wind tunnel tests of fins with different freeplay angles are carried out, and the vibration is observed by accelerometers and the high-speed camera. Based on the tests at the case of 0° AOAs, the fins within the same freeplay angle are tested in the wind tunnel under different AOAs. The result showed that the flutter speed increased due to the existence of the freeplay. As long as the increase of the freeplay angle, the flutter speed increases. The aerodynamic load could decrease the influence of the freeplay. Along with the increase of the AOA, the flutter speed decreases untill to the linear flutter speed.
