I have an OS 46 VF which has a front carburator and rear exhaust. I also have an OS 46 VR DF which has a rear carburator and rear exhaust. They both have the same case as it is marked with a V. The only difference I see is where the carburator is mounted. My question is; Given the same size prop will they perform the same? I am trying to decide which one would be the best on the plane called the Vertigo which is a VTOL plane. The engine will not use a tuned pipe.
