Check your cabin heat valve for either the arm slipping on the shaft, cable slipped, or valve plate lose on the shaft. All 3 have happened to me in one ac or another ( 2 of them zeniths).

<p>If its 100 degrees in the cockpit with the outside air temp at 40 degrees, you may need to look at the airflow thru your cowling. You must have a very high temp in your engine compartment to generate that kind of cockpit temperature. </p>
<p></p>
<p>You have 40 degree air going into your engine compartment and 40 degree air coming on thru your vents - and its still 100 degrees in the cockpit. That just doesnt seem right.</p>

<p>I fly my 601 xl in 100 deg. takeoff temps but by the time i get up to 5500 feet or so, it's cool in the cockpit. My engine is an O-235 and I have the larger Vans SV eyeball vents connected to the standard NACA inlets.</p>

<p>I do have the Rosen sunshade.</p>

<p>Hello Eugene,</p>
<p>Another thing to consider is hot air from the cowling being sucked into the cockpit. While flying there is actually a negative pressure created within the cockpit if not well vented from the outside with positive pressure. Be sure to review the firewall sealing for potential entry points of hot air. Just an alternate possibility to consider. Many times problems can be caused by an assortment of issues with cumulative effect. </p>

<p>Take a look around your fuse and I think you'll find plenty outlets for the escape air.This subject was addressed before after I went out and purchased grills for escape vents and of course, they could not be returned.</p>

<p>Patrick gave an excellent report on the Vans vents. Just wanted to say that I’m in DFW and had them in my Sonex. You will not believe how much air comes thru those vents!!! It’s almost inconvenient to have anything like paper or pieces of fabric with you because it’ll just be blown around. Again, no ducting involved. Just the little flap that was by my knee. Easy open/close. I often flew with only one side open, even here in Texas. </p>

<p>Hi Eugene. Thanks for this post about the 601 being hot, despite the outside air temperature being 40 degrees. I live in Socorro NM. 41 miles south of Belen. I fly a 701. But I am building a 650B. I wondered about temperatures in the glass canopy. I saw a picture with snap vents in the canopy. For a total of 4 vents.Does a person need to provide an escape route for all the incoming air. I assume you have a sun shade. I also thought about a tinted canopy.</p>

<p>No typo. I personally walked the guy from Koger over to see my airplane at Oshkosh 2013 when I was shopping for a sunshade (he originally wanted to sell me a one-piece sunshade for a 601, and he'd never seen the two-piece split canopy of the 650). </p>
<p></p>
<p>He measured the canopy sections on my airplane, and then gave me a quote of well over $1,000. He said it was double the price of a custom sunshade because it was really two separate custom pieces.</p>

<p></p>
<p>If he's now selling them for anywhere near $200, then either something has changed (maybe he can make them cheaper now), or maybe he's selling a one-piece one-size-fits-all sunshade that they mass produce, instead of something for the two-piece canopy.</p>
<p></p>
<p>If it works, it works. And if it works for $200, then that's even better. Perhaps it would be more accurate to say that the Walmart shades are only $190 cheaper, but I imagine the Koger ones do look a lot nicer.</p>
<p></p>
<p>I was stationed in Florida. Don't recall it being any hotter there than it is here in Texas, but I was a lot younger then. It's right at 100 degrees here right now, as I type this... ;-)</p>

<p>I can’t get a shot of the vents in the canopy, but they are the standard plastic vents that aircraft spruce sells, they are pop in that rotate for air flow.</p>
<p>next time at the airport I’ll take a pic for you.</p>
<p> but they are on the forward sides of the canopy.</p>
<p>as far as a Walmart sun shield, the Kroger shield covers almost the entire canopy, is adjustable to any length in a second.</p>
<p>the Walmart shield wouldn’t cut it here in Florida.</p>
<p>$1000 less, must be a typo…</p>
