Default Wiring Diagram

I'd like to run some wiring for two of these units before I close the front skin. Is there a wiring diagram available? All I've found on the website is a video.

Default one other aspect to report...

I flew to lunch yesterday and OAT was around 80F. I left the cowl flaps open while parked, ate, returned and fired up the engine. Normally I don't have terrible problems hot starting but it frequently takes once of hitting the start button, advancing the mixture, catching and then dying and then doing it again and then it keeps running on the second time. It also then has the typical injected rough idle due to fuel still boiling in the injector lines.

Well yesterday's hot start was on the first time after only a very few blades and it idled very nicely thank you very much Now this is admittedly a sample size of ONE but I do believe that leaving the cowl flaps open on a short turn around might help to purge the hot air and reduce the hot engine rough idle problem.

Smile Cowl Flap

Im looking to install cowl flaps in an RV6 ,but not for CHT which run very cool. I would like to know how much an affect they have on oil temp when you install and report to us RV drivers your results.
Thanks Bob

Default RV-8 Install?

Has anyone installed these on a -8? I measured and I don't think there is enough room without getting into the curve of the cowling. Any thoughts from -8 installers?

Default effect on oil temp

I have a friend at Livermore who installed 2 cowl flaps to help with his oil temps. He doesn't seem as happy as I am, but that's hardly scientific

I will try to press him for more objective data but I think it will require significantly more patience to test it as oil temps take a lot longer to stabilize. I should say at this point that when I initially tested my plane I was very oil temp limited until I bit the bullet and installed a MUCH BIGGER oil cooler. That solved the oil temp problem, but I still had CHT problems until I installed the cowl flaps.

I dont have an -8 but I did install one on the RV-4 in the center rear section of the bottom cowling instead of on the sides.

I thought about that, but what a hot, brutal environment right by the exhaust. Do have any pics of the installation?

For my RV-4, its actually the best spot as far as distance from the 4 exhaust pipes.

See post #95.

... If possible I would like to see some photos as well. I don't have access to a RV4 so I have very little information when asked. Thanks much, Allan...
