    You'll need a DeWalt one if you want it to match your plane

    Millwaukee heated jacket. Works great, has 3 heat settings. Ive been wearing it everywhere. Red is a poor choice for a guy who cant stay clean. The jacket rocks, lasts 8 hrs on low.


    I have made a couple of passes at more cabin heat with some real good results. I flew this morning for 1/2 hr at sunrise 5 below zero, the cabin pretty comfy. Not overblown yet, but were getting there. Will post up my changes when I get the thing where it looks good and works better. There is hope yet to fly with no gloves and hat.

    If you are to shy to post the "in the works" photos or you're waiting for the Patent, you could always send them to my private (Clinton) approved email server. How long are you going to keep a friend in the cold?

    i have made a couple of revisions to my experiments. It's still just a gorilla tape hack job right now. I spent a fair amount of time studying my friends Carbon Cub air intakes. The carbon fiber air intake on the CC is much more sanitary than the alum periscope on the sport cubs, not sure if it helps
    The problem is two fold, the heat muff doesn't make enough heat below about 10 degrees, and there is not enough airflow thru the muff. I had my local fabrication shop in the hangar today working on my idea. Hope to have a somewhat final version by the weekend. Will show you Sat when you come over to Alton Bay for lunch

    Yep, company (Hot Headz) confirmed 3.5 amps for the one I'm using.

    My mechanic said that he brazed screws to a pipe in an RV-6 to get this kind of heat radiation. He said that worked very well. Only in experimentals, though...

    I pulled the Sport Cub heat muff off tonight to try the wrapping a spring trick and found this

Harley realized long ago that there was good money to be made selling it's customers logo branded apparel they were proud to wear. And you have already created the market by selling them an airplane with very little heat.

    What type of spring are you thinking of,
    maybe adding fender washers and nuts for additional surface area?

    If Jim put the springs in would like to hear report on how much it helped

    That's certainly not the case on the 2014 CC EX. I would think that should help quite a bit.

    As far as the springs, I would think that would help. Also a copper mesh, like the pot scrubber things, would help transfer heat. Of course, any restriction in the muff will greatly hinder air flow--a two pronged problem.

    As far as basic calculations for a sanity check: If you're burning 5 gal / hr, the max BTU generated is going to be about 560,000 give or take. You probably dissipate 1/2 of that heat in the cylinders so that leaves 280,000 going out the pipes. There are four pipes, so we have about 70,000 BTU per pipe to work with. You would think we could keep the cabin warm with that, right?
