In the very hypothetic case that I would like to replace one of my extremely powerful and reliable 46AX for an OS 4-stroke... what model would give me the same performance? My planes are a Bridi Advance trainer and a low wing design (very similar to a Sig 4* 40) and both have unlimited vertical performance, something that I wouldn't like to exchange.

Additional information: I use MA 11x6 and APC 11x6, with Byron 5% fuel.

All coments helps. Thanks
