Flew up to visit Zane + Maule heater effectiveness

Couple weeks ago I got to visit Zane's new playground. It was -18C, but we made the best of it with chili dogs.

Right on, good to see planes getting used in the slow season. And thermometers being read in Celsius. :D

Man, not even chili dogs could keep me warm in those conditions. You must have anti-freeze for blood.

Awesome stuff. Hard to believe there was slush under there with the temps that low. Snow blanket insulation works.

Great video and I'm thinking Zane made the right decision to move to Minnesota. Even down here when riding my bicycle I have to deal with those snow mobiles that sound like supercharged bees.

Re: Flew up to visit Zane

The slush was mostly history by the following weekend after a week of super low temps. Either the surface had firmed up or the slush did. Either way it's not a factor currently. I went for a ski last weekend and it was crusty and hard.

Re: Flew up to visit Zane

Fun times and fun video. But….please tell me you didnt use a broom to clean off your windshield #-o . Looks like your heater wasn't putting out much heat since we could see your breath. I bet those chili dogs were yummy!

Re: Flew up to visit Zane

The broom made me wince too, but I presumed it’s a soft one used for nothing but airplane snow removal. And hey it’s his plane, his choice of removal. :D

Even then, I’ve been forced into the servitude of polishing too many windscreens at work on slow winter hangar days to remove micro scratches. I’m inordinately sensitive to window care.

Better to see it treated a tad too bush and actually flown than to see a pristine hangar queen treated to clean microfiber and silicone squeegees.

Yup, very soft brush and it's not like I was scrubbing. Just removing 97% of the snow so that the heater and the sun could sublimate the rest.

And *a thousand times yes* I believe in flying airplanes. If that means that the windshield has to be replaced every 8 years instead of 20, so be it. It's a pretty cheap thing to do. Like one AMU. So $100 or $150 per year for the ability to use the plane more. Honestly, I kind of wish I needed one now, since I need to pull things apart to replace the panel cover anyway. Really, the entire interior is due for a 20 year refresh, but you've seen the videos so you know this. :lol:

Maule heat is weak sauce. Love the plane. Love the people. But the heat is awful. Good thing I'm in the "dress for the crash" school anyway.

Re: Flew up to visit Zane

Do you have the Aux heat/ heat cuffs on both exhausts? I can melt peanut butter on the floor in mine with temps below zero. We did exactly that on the way home from Alaska. Now the drafts up top are cold but the heat cranks. Seal up the drafts. It's worth it.

You have an M5? I have an M7. I've gotten a couple reports about the 5 having plenty of heat. But I'm still chasing a solution in the 7. I have the drafts somewhat under control with closed cell foam, and the floor vent puts out decent heat, but otherwise not much.

Yes mine is an M-5. Do you have a heat outlet between the left set of rudder pedals and/or one under the right seat? The one on the pilot's feet definitely makes a huge difference. Keep the feet warm and all feels great. I was trying to check your heat controls in your videos but never saw a close up anywhere.

Hear hear! Bravo, I’ve got a 185 I bought that isn’t shiny, and she’s for doing what you do. Getting out and seeing things and doing things. :D

Had the same exact issue with a customer of mine. His 5 had great heat, went to the 7 and it was terrible. Even with the aux heater. He sold it.

Re: Flew up to visit Zane

Very interesting. Have any pictures of the baffling, heat muffs, scat tubing, slide valves etc for the 7? I wonder what changed. Any idea if it's an airflow issue or just blowing cold air not enough heat transfer in the muffs?

Re: Flew up to visit Zane

Right muff heat comes from outside of right cylinder baffle through the muff and valve then goes to defrosters and under right front seat floor outlet. This one melted Peanut butter on the floor

Left tailpipe muff goes from left cylinder aft baffle back through muff then valve through firewall and right between pilot’s rudder pedals. Tons of flow and had the sole on a shoe actually come loose from the glue melting.

Ah that was Zane! I just watched the video last night when I got home from a biz trip. Thanks Rich!

I'm curious if the added rear seat heat really takes away from the effectiveness 9f the heater in the M7. It is truly a rear seat heat as it comes up under the middle seat, so it doesn't warm them up, just warms the baggage area as very few that I know actually use that for a seat.

Re: Flew up to visit Zane

Great video! Love your content.

What did you have to do to warm up the motor? Did that blanket do enough?
