The builder installed an oil cooler shutter with the oil cooler installed on the rear baffle behind Cylinder #4. I've closed the shutter fully and the temp is still in the 174 deg F range. I've heard you can remove the oil coolers from the RV3's and 4's. FYI. My oil temp sensor is a UMA brand and I called the manufacturer and got the ohm values for various temps. The ohms vary about 0.5 ohms per 5 deg F, if I remember correctly. The manuf stated a min of 20 gauge wire should be used and the connection should be soldered instead of using connectors to extend the leads of the sensor. I noticed my oil temp before starting the plane was about 17 deg F higher than the OAT. After changing the wire gauge from 22 to 20ga and removing the connectors the oil temp was close to the OAT temp before starting.
How many of you don't have temps above 180 deg F?
How many of you don't have oil coolers and what are your temps in the summer?
Thanks
