That is exactly what I am trying to accomplish. Get a HDS 5 in a 5 gallon bucket. The Vexilar packs have a fixed width if the width of the gimbal is real close or wider than my hds I can make it work. I am going to check my ICE-35 mount tonight but I don't see that I can order one of them. I don't know if the Marcum non lithium shuttles fit in a bucket if they did then I could just use my current gimbal in that. I do have a soft pack for the hds but prefer the form of the shuttle.
