Brief Description: RV-10 vents in side of boot cowl
We had a return trip from Idaho in a Cherokee 235 a couple of weeks ago. It was a little bumpy and pretty darn hot even at 10.5K. The chief pilot informed me that I better have some better venting in the Bearhawk.
I have a expert builder friend that suggested I try the RV-10 vent kit. They are simple, light and effective. He has them in a Rebel, RV-4, and RV-12 and worked pretty good when I've flown with him.
