Are any of you guys or  gals experiencing extremes of heat in the cockpit while flying.  I got a  Kroger sun shade and installed it thus eliminating direct sunlight but am still  getting a lot of unwanted heat from I suppose the engine compartment even though  I closed off the extra space in the slots where the steering rods go through the  firewall.  Are any of you having the same problem and what are you doing  about it.

I have a 701 and live in the desert (Tucson, AZ) and I get lots of heat from it. I wish I had put aluminum for the skylite instead of lexan. It seems to be dirty all the time anyway and I seldom look up through it. I am sure I will be replacing it in a few short years because of deterioration. If it was aluminum it would still be fine after thirty years or more.

I put a layer of insulation on the cabin side of the firewall during construction. I don't feel any heat from the firewall, so it seems to work.

Bryan, what type of insulation did you use?

I got some stuff from J.C. Whitney that I used for the cabin floor also. The stuff is designed to be used under the carpeting in a car. It's basically shredded rags treated with fire retardant and glued to a sheet of aluminum foil. It's about half and inch thick. It holds up pretty well under the flooring and works as sound and heat insulation.

Home Depot sells a product that might be slightly better for firewall insulation. It's used as air duct insulation. It's half an inch of fiberglass insulation glued to aluminum foil. It is probably a bit lighter than the stuff I used. You'd have to seal it up pretty well with aluminum tape to the keep glass fibers from getting into everything.

I just bought a couple of rubber shift stick boots out of the JC Whitney catalog to seal off the nosewheel steering rods. I bought the closed cell foam sheet insulation from AS but I don't know how well it will work yet.

To attach it to the firewall did you just use glue?

I was thinking about using those snap -together floor mat s that are 24x24 

sq. they 're about  1/2 " thick  . I'm sure they will kill all the vib. 

sound ,going to glue them to the inside of the fire wall, floor ,and floor 

sides also,the rear storeage shelf and the over head of the shelf .Ifire 

tested them with a tourch they didn't want to burn,and didn't put off any 

bad smoke going to fit them tight around thr steering rods with just a slit 

for the rod to travel up and down, the whole bundle couldn't be over a 

couple of lbs.  you can get them in any color  Home Depot, harbor freight, 

cheap....I think they will do a great job ..    Joe N101HD  601XL

I used a spray on adhesive similar to what I used to glue the seat foam together and then taped around the exposed edges with aluminum tape. It's held on tight for two years now.

Bryan,

      Could you be more specific  as to what kind of spray on glue you used and where is it available.  Also  what did you glue on and where is it available.  My ZodiacXL is completed  and flying so it will not be easy to install a heat shield but I have to do  something because the cockpit heat is unbearable and will get worse as the  summer gets hotter.

I think this is the same insulation I used from J.C. Whitney:   http://tinyurl.com/2foco5and they sell an adhesive for it:  http://tinyurl.com/2b7p23

I've also seen fiberglass air duct insulation with a foil backing at Home Depot that might work well.The adhesive I used, I bought either from ACE hardware or Home Depot.

3M Super 77 was one type I have used: http://tinyurl.com/2xo8sk 

Office Depot also sells it: http://tinyurl.com/2uth3y

The ACE store had another brand of spray adhesive that also worked well. A brush-on contact cement might also work well.

I had the stock Jabiru muffler until I had two weld failures.

I replaced the stock muffler with homemade pipes that extend behind the

cockpit (it's in the archive).



The stock Jabiru mufflers dump the hot exhaust directly under the cockpit

floor. Put your hand on it - the floor it's hot. I put a piece of metal

between the Jabiru exhaust pipes and the cockpit floor, that helped some.

But dumping the heat further away helped more.



Also, I stick a couple of pens underneath the front of the canopy -

between the canopy and the forward top skin. That gives a stream of

air that helps cool the cockpit. (It's recommended by Chris Heintz.)



I also put a pipe vent on each side of the cockpit to get more air.

Can't open a window - that canopy does get hot in the sun.

JC Whitney sells some pretty inexpensive heat/sound

insulation that I may use on my XL. Search for

ml274040.

 

http://www.jcwhitney.com/autoparts/Search?catalogId=10101&storeId=10101&sku=ml274040

Another supplier, although more expensive but maybe a

better product, is pegasusautoracing.com. Search for

part #1832.
