I had to stuff things in around the seat to cut down on the freezing cold air  coming in from various places overcomming the anemic heat source yesterday. Had to come down to 11500 ( taking advantage of the 70mp tail winds), and legs still shaking. 2 questions. Anybody tried adding a 2nd heat muff on the rt exaust, and 2, is it practicle to try and cover the inspection panels for the flap actuators. I have insulated the fluting on the baagage bulkhead, but still get lots of cold air. I got the drawings for the actuator covers, but dont see that as a good seal. Charlie Heathco

Hi Charlie,



I bought an insulated USAF flight suit (Nomex and never worn, $100) and wear

felt lined boots, gloves and a hat.

Charlie, we have 2 heat muffs on our 7. We bought it in MSP so they were  

being prepared for the COLD. I have no idea what you may encounter in the  

process. Appears that it would not be a problem to add it.

Charlie,



A lot of the cold air may be coming up between your legs from the opening 

for the control stick.  I get a lot of cold air there - nice in the summer, 

but brutal in cold weather.  I have seen various schemes to keep the cold 

air from entering underneath the floor pan through the aileron push tube 

holes in side of fuselage.



I am considering using a control stick boot to at least cut down on the air 

flow.

I built 2 RV-6A's which I flew in northern British Columbia.



I installed two heat muffs with two entrances into the cockpit.

I insulated all the side walls including under the panel.

I installed boots around the aileron push tubes (the biggest offender for

cold air)

I put weatherstrip under the rear skirt on the slider canopy as well as

along the side skirts. (2nd biggest offender)

I never did the baggage bulkheads or the flap actuator rods.



The plane was comfortable to fly down to about -15 or -20 deg celsius.

I had the same problem 4 years ago when I flew to Rochester, MN. It was

10F below when I landed. My daughter and I were dawn cold.

Later I added a second heat muff, built aileron boots to cover the push

tube exit hole. I also insulated the panel where the flap horn exits.

I have a slider and I placed some thin weather stripping at the very

edge of the back of the canopy.

Another thing is the air coming in along the side of the canopy. A

simple fix is to get some 1/2" foam pipe insulation, and cut to lengths

that will sit between the front part of the slider and the locking block

in back. Simply put these in place after you have the canopy closed and

are ready to taxi.

After these fixes we flew very comfortably when temperatures were below

0 F.

PS I don't recommend flying when temperatures at 10 below F.

There is an amazing amount of air that flows from around the edges of the 

canopy - especially the rear area.  I put weather strip around the canopy,  boots 

around the airleron control rods thru the fusealge, and boots on the stick.  

The combination made an enormous difference.

My 6A had a second heat muff and it did nothing but negatively impact

cooling air exiting the airplane (with oil temp problems).  I now just

use one heat muff and it is probably better.



I also have the drafty issues and fixing those is among the best

remedies (along with Stephen's warm clothing comment).

I just ordered my exhaust system from Vetterman - with dual heater/mufflers.  It gets cold here on the DelMarVa peninsula...



I'm also interested in what everyone else has done / is doing to cure this.....

I would run each heat muff to a separate entry into the cockpit.



One for pilot and one for pax.

That was part of that plan...I also have injection so the induction system doesn't need heat.......

Vans recommends plumbing the 2 heat muffs in series.
