Flashing Lane B after initial start and warm up

Hi Peter

Perhaps start with a check of the sensor values as shown in the Heavy Maintenance Manual.

Cheers

sorry, did not attach it for you...

Not sure if you've got it solved already, but here's my 2 cents-

What battery are you using? The only time I've gotten flashing lane lights on startup was with lead-acid batteries that don't have enough CCA. They usually work fine for about 50-100 hours before it starts doing it. That's usually right at startup though, not after it's running for a while. Lipo batteries like Earth-X solve this version of the problem.

Your oil temp looks right for idling a few minutes after startup, but the coolant is wildly high... you can pretty much idle on a hot day for an hour without moving, and it still probably wouldn't get that high on a Sling. Usually we have to do tricks to keep the coolant temp UP to run the heater, but never have to do anything to keep it down. Have you always had this high of coolant temps?

If your oil temp sensor ohms out correctly, I'd investigate the coolant system. I see you don't have a thermostat, but if you have tape on your radiator, remove it. If no tape is installed, check the system for kinked lines, check the coolant temp sensors, make sure within spec. Last, maybe the water pump is damaged and not moving coolant through the system well enough? 

Thanks Evan, some useful ideas to try there.  It's a lead acid battery. No tape on coolant radiator.

I will go back through the g3x data logs and see what coolant temps I got last spring. But I think it's always been around 100C . Could have crept up a bit as 114C soon after start up is a bit high. In flight it's lower and quite stable. Thanks for your comments. 

100c is too high also unless it's very hot outside. You've got something wrong with your coolant system, 100% for sure.
