Up for sale is an OS 32 engine that I just took off of my Raptor. I purchased this heli with this engine in it and it runs perfectly without any problems. Starts right up and runs strong.
I upgraded my engie to a 50 size so I have no use for this engine. As best I can tell this engine is a ringed OS SX-HX ringed. I took a lot of pictures so you can see all the details of the engine. One corner of the heat sink has 4 broken fins [see pictures]
I took the engine apart and thoroughly cleaned it.
My local hobby shop lists the different versions of this engine as follows:
OS .32 SX-H Non-Ringed (12956) 119.00
OS .32SX-H Heli Engine Ringed (12956) 137.49

The specs of the engine from the OS site is below.

Larger front bearing and rear bearing w/nylon retainer maintain smooth power delivery
Type 20C Carb features larger, 7.5 mm throat and dual needle valve stabilizes hovering and adds to top end power
