Am i correct here? The current OS .32 avaliable is the "SX." Prior to the "SX", there was the "SF." Then prior to the "SF", there was the "F". All I believe were avaliable in an Heli or ABC version.

Or did the "F" precede the "SX"?

Please help.

The current OS 32 is the SX. Prior to the SX was the F. Prior to that was the 28 F I believe.
There was no SF version of either. Both the 32SX and 32F are excellent engines.

The 32F was available as ringed or ABC (ABN) for Helis but only ABC (ABN) for planes although you could easily convert the plane version to ringed with the right parts - same with the 32SX.

The 32sx is a bad little motor. I own one and love it. They only thing that runs better that 32 is my YS 63.

Anyway the 32sx is a great motor. I have heard that "F" is even better because it is a little lighter, but has the same RPM output.

Ryan take a look at the Webra.32 Speed, it's got lots more power and runs better than the OS. It's a little less $$$ too.

Already have the OS "F". Was NIB until I test ran it yesterday. Turned an APC 10x6 @ 12,700 RPM. Engine was hardly rich when I checked the RPM. Will run rich a little longer before leaning it out. What can I say: AWESOME!
