Hawker Hunter air-brake detail and correction set 1x lower fuselage section 1x air-brake actuator 1x air-brake panel. Correct one of the few shortcomings of the Revell kit with this simple to use set. This includes the characteristic trough in which the air-brake actuator rests when the air-brake is closed. Remember the Hunter's air-brake remains closed on the ground, although drooping is common.
