RE: Mini-Dust
Interesting that the engine will run without a bladder tank. The venturi's very large on AMEs (and smaller on a BigMig). On ours, we cut the 5x3 prop down to about 4 inches (you'll need to play with the diameter somewhat to get it right). I like the Sucrets tank.. British Combat fliers used to use Coleman's Mustard cans to make fuel tanks back in the 1970s.
