Does anyone know if you can use bravo trim pumps to operate 280 k-planes? I wonder if the pressures / flow rates are the same in the two pumps. What does a set of k-plane pumps cost? Thanks.

Sure you can, same basic pump. We sell them for $375 complete. You just have to be sure to connect the hi pressure side to the top of the cylinder.

As Marc said, yes you can. But they will move much quicker. The flow rate is quite a bit faster then tab pumps. The pressures are different too, but shouldn't be a problem if you make sure you hook up the "UP" (left hand port as you look at it) to the line that connects to the top of the cylinder to push the tab down. Sounds backwards doesn't it. All of these type pumps are this way because the high pressure port is for pushing out/up on the drive against prop thrust. When they use them on tabs, it's backwards.
