RE: New Patriot XL
Looks like you have OS91FX for power. I upgraded the muffler to the Jettstream, more RPM and better high octane sound. APC 11x9 prop will give better efficiency than the MA. Flaps are very useful to slow it down for landing. I also use half flap deflection to shorten take off, otherwise tougher to do on grass runway. Don't forget to put on some air whistles from i4C for that turbine sound...
