[b]I have to be fair here. A local flying buddy who is also in twins has been having engine problems in them. GMS 32 engines shelling their rod bearings, the Magnum XLS 52s wont run together, but his planes running pairs of the OS 46 AX engines just keep going. He says he's becoming an OS fan.

As far as I know he's not tried the Thunder Tiger engines.
