Rans S21 Build - ep 38 - Engine Baffling 2

[@gotchagoing4905]

On the left front engine baffle and the 'mystery' plate that it bolted to the front left side of your engine with 4 bolts. Wouldn't that be where your prop gov for your CS prop goes? I'm thinking that's why the cover plate. And about that bracket on the front top of your engine, have you thought about turning that upside down and fastening that to your front baffling without that small plate you made?

[@treetopflight7624]

Yes, I believe that I mention that the plate cover is for the CS gear box/governor. Unfortunately, there is some engine casing that sticks out that does not allow that bracket to be turned upside down (hard to see in the video). I could fabricate a new bracket (not hard) but I'm waiting to see if my "EZ" solution works. There is very little stress on that bracket, and I will leave it if the cowling fits.

Is all this baffling just to route the air intake from the coweling around the engine and then to the underside?

[@treetopflight7624]

basically yes. The air is forced around the cylinder fins and down. Some is forced to the oil cooler (which looks like a small radiator) and some is forced to cabin air ducts.
