They were within 2. Just change the oil and antifreeze each year. Starts and runs like new.

My first attempt was to no avail also. 40mm seemed to work much better.

I just completed the first flight of 601XL C-GYXQ today. The plane flew wonderfully. No real surprises other than: 1) I found aileron control to require more force than I expected, 2) the oil temp was getting close to max on the 912S even though it wasn't a warm day and I wasn't maxing out the RPM by any means. Can anyone offer typical temperature ranges for the 912S that you are experiencing? I'm reading 185F on the CHT (liquid) and 260F on the oil temp. I'd prefer to see the oil around 200F. I have an oil cooler installed with air coming in from a Naca in the cowl. I know I can do a better job of sealing the intake to the oil cooler, so I'll try that next to see if that reduces the temps at all.

The oil temp at 260f is hard to believe since you were not running the motor hard. You need good negative pressure on the outflow side of the oil cooler. The NACA duct really is not intended for high presure ram air and will not perform properly unless the air is sucked through the oil cooler. Congrats on the first flight. I bet the smiles are still there hours after ya landed.
