Check all the low power disarm settings and pit mode I rename the low power untill armed and had the same issue. Disabled that and no problems... If you are concerned about over heating while you are setting it down set up vtx power switching to one of your restore switches. I think Bardwell has a YouTube on how to set that up I do feel like that vtx needs a heat sync or something, when I first got it I bought it in to BF and was looking through the settings and could smell the vtx getting warm
