I am currently using a 90cc plastic tank from Hobby King. It's supposed to be a clunk tank, but I am using a rigid pickup tube. I set it up as uniflow, with the uniflow vent at the front of the tank, along the outboard side, slightly above center. Rotating the uniflow vent up or down inside the tank gives the same result as moving the tank up or down to equalize the run. I am running on suction with a 1/4" venturi with a spraybar through the center on an OS 32F. I am using a plastic Bolly 8.5 x6 prop, mostly because I have a decent stash of them.
