I've had mine posed that way for about 6 months so I hope not! I did take him down after a couple of months to tweak the pose a bit and I didn't notice any issues then - should probably check this weekend. I think the biggest risk might be strain on the jetpack fixings as the figure settles into the clamp.I just want to display Boba in his flying pose fighting with Sarlacc pit. Would it damage the body if you keep him in that flying stance for a long time guys ?
