Hi there,



last week I did circuits for 4 days

in a row, my CO-detector went

off the most of the time and I was

sick like a dog.

I had my exhaust stacks extended

but apparantley it made no difference.

All the holes in the wheel wells and

flap well are sealed. I have the feeling

the fumes enter the aircraft mainly

through the canopy.



Did anybody got rid of that CO-problem

by now - if yes - every constructive input

is very much appreciated.



Cheers

The only way to solve it is to go to a self contained compressed air

system. The use of a diluter demand valve entrains ambient air so you still

get CO if it is present in the cabin. The CO scrubbers are extremely

expensive and generate alot of heat in that they use an exothermic reation

to reduce the CO to CO2. They work at the same temp as your catalytic

converter. Atleast the ones used by NASCAR do. The NASCAR guys would not

even talk to me. F1 it is! They know how to turn right and left when

racing. Sorry for the lapse!

Now, there is a company called Whiff's that make CO / Smoke absorbant

filters for wildfire fighters.They are disposable. These filters last about

4-8 hours depending on the environment you use them in. The filters are

called Excapers. You can get more info on them at

http://www.whiffs.net/about/index.html. The individual filters are about

$6.50 each. The mask that you use them with is pretty funky looking though.

Have not tried them out yet though. Just found out about them about a week

ago.

Our 52 was getting lots of smoke in the cockpit any time we turned the 

smoke on, then several Yakkers discussed the co problem, sooo--we 

purchased a professional quality co meter, tied it around our necks and 

test flew the Yak--hardly off the ground when it pegged and said vacate 

the premises ( unit built for home use).  Next we put shop air in the 

exhaust stack and bubble checked all exhaust flanges and smoke nozzle 

flanges.  Smoke nozzles were the worst culprit plus two badly leaking 

flanges.  After leak correction and several more test flights, the only 

time we could get co readings above .05 was taxing with the canopy 

open.  Hope this helps>
