| Subject: | Revisiting and old topic... CO in the cockpit. ** UPDATE!!! |
Hello all. Well, my airplane is completed. My "restoration" over the course of
the winter has solved my CO problem, and I can now accurately tell you where and
how it got in. My IN-FLIGHT CO readings are humorous now....
In normal climb, 2ppm. Cruise, 1ppm, and slow dirty flight, 4-5ppm. THATS IT!!!
Does my co machine thingy work? Oh yes it does! Went off in my garage after only
a short time of running my propane heater mid winter. I've got her sealed
up good and tight, but not, if that makes any sense. I sealed the seat backs,
and rubber booted the steering rods. Extended the exhaust down, dooowwwwwn another
10" or more. Got it down and away from the plane. Well, my shiny new interior
has a really neat centre boot that covers up the Y stick. It's not a tight
fit around the stick, but get this. Here is the airflow of the 601..... Canopy
creates a low pressure in the cockpit, and air RUSHES up through the tail,
desperately trying to equalize. In my case, being sealed up so well, the only
place it could show itself was through the centre column. Air is ballooning out
my Y stick center console cover. This is the source of the CO. It's air coming
from the tail. If there is ANY exhaust stuck to the fuselage it will become
part of this mass of air entering through the tail. Extending the exhaust Down
so low, sealing the firewall, and the problem WILL go away entirely. I have
a brand new custom exhaust because the original was leaking like a sieve. Hopefully
I can post a picture of the finished product, or a link to the flickr account
where you will see one hell of a transformation! This airplane is near
PERFECT now! Having some issues with my flap motor, but I think it's a bad switch.
Future updates on that problem.
Cheers, and I hope this helps others that have encountered the same problem. Just
get that exhaust down and as far away from the fuselage as possible, as long
as the exhaust stack doesn't hit the ground, you are long enough!
Cheers!
Chad
