Hi All, I have an Ovation 2GX with the 310 HP STC conversion. Only one new chart in the POH per the STC paperwork. Anyone know where to find data on Cruise Settings operation.? My POH has data for the 280 HP engine. Perhaps I should just get a 3GX POH. Is there a good source for POHs?   I just upgraded to Performance level in ForeFlight and they may have the other data for runway and climb performance. Thanks as Always!
