We realised the HL King Tiger Henschel Turret is not easy to modify for recoil as the barrel won't fit without machining. So we made a small batch of KT Henschel turrets complete with servo recoil, elevation and magnetised the 2 halves for easy access.
plug and play for HL upper hulls, as it is the large turret ring. (no turret ring is included.
you will need to use HL v6.1 or any upgrade boards that supports servo outputs
the paint is not perfect so some minor touch up or painting is needed
