I have a P-100RX that I use on a F-16 and my Blanik. The RX engines make it easy to swap turbines. As a matter of fact, I swap the turbine, ecu and pump. The reason I do the pump is because the RX engines have pumps that don't have a fixed lead on the back. The lead plugs into the back of the pump making it easy to pop out. I got JC to send me the wire harness, an i/o board, mount and some fittings. It cost me $280 and now I double the use of my P-100. I can switch it over in less than 30min. Just buy some extra festo caps to seal off the fuel lines when the turbine is removed.
