It's lightweight, and simple to install. I don't see anything wrong with it. However, it is not a 50-60A car alternator. I am looking closely at my power budget as I have chosen to use a Comp-U-Fire ignition which can consume up to 12A in the static state. I think it is more likely to consume about 8A while running, but I haven't checked this yet. This plus the current requirements for a fuel pump, and a radio get you to about half of the alternator output. Don't forget, you also want to recharge the battery after engine start. So, you have to consider that you can't hang everything on the alternator you might want. In my case my radio and transponder will only take about 3A worst case so I have lots of room left...

The idea of using an electric heater in a KR seems like a Salvador Dali kinda thing to me. In an aero engine, we throw away about 75% of the heat energy. So poking a hole in the firewall could make sense.

With the Soob, there is nice heated water available to use for cabin heat. The discussions were excellent; lots of ideas and simple heat exchangers (concensus was a heater core out of a Ford Econoline van makes the best heater, but that's for something the size of a Murphy Rebel), but the controversy centered around the safety of piping hot fluid into the cabin. The 'cons' didn't want to chance a leak while inflight, and the fix was to provide some stop cocks which could be closed in a hurry (but think about the fun it would be reaching back under the inst. panel of a KR while inflight, two-up, trying to find those #@!%!! shutoff valves with hot coolant spraying around!). The 'pros' argued that it's done in millions of cars and trucks and when was the last time you heard about somebody getting hot coolant in their lap in a car? So again, let's call it a preference. My own choice- if I have it available, I'm going to use it. That way I can put the heat exchanger where I want it, and no chance of getting carbon mono in the cabin. No drain on the electric system, and the heat is always available when the fan's turning. As to using an electric heater- I can't see myself at 10,000 ft. over the beautiful skies of Oregon in the winter... huddled around a 100 watt light bulb to keep warm. It was bad enough in the C-150 in Texas, with heat muff cabin heat- I remember one night flight at that altitude after a cold front. I could see the glow from every city within 150 mi., when my teeth would stop chattering long enough. Makes you appreciate the beauty of VFR night, though, and makes you realize just how little there is between you and the cold air outside. I'm sure Mike has fond memories of flying in Alaska in bermuda shorts and a tank top, right? ;o) Oscar Zuniga Medford, Oregon ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ------------------------------ Date: Mon, 26 Jan 1998 10:26:05 EST From: RFreibe131@aol.com Subject: KR: V-tail KR2 I would be willing to design a linkage system for a v-tail 2 if someone else will do the aerodynamics ( Size and Angle) Ron ------------------------------ Date: Mon, 26 Jan 1998 11:20:19 EST From: Willard561@aol.com Subject: Re: KR: Alternative alternators (formerly Cabin heat) In a message dated 98-01-26 01:02:32 EST, MikeTnyc@aol.com writes: << But we really don't need to use just alternators of this style. You could easily modify the alternative engine installation on page 99 of the manual to run another alternator that way, with the alternator on the belt drive instead of the magneto.

Although electric heat would make quick and clean work of the heater issue, I think I would rather go the exaust manifold heat exchanger route rather than electric heat since you get the exaust heat for pretty much free anyway. And like one of you mentioned, if it's still too cold, you can always plug in some electric socks! :) My concern was really if there are any gotcha's with respect to cabin heat in the KR, but apparently not. With these alternators, though, isn't the output drop at lower RPMs a product of the alternator drive ratio? I mean, it seems it would be possible to drive it a little faster with a different ratio so you could run all your gizmos without sacrificing your battery charge. Or is there a mechanical limitation somehow with the VW setup? Or are we trying to save a couple of horse power by under driving the alternator?

Indeed, winter survival gear is particularly a good idea on those trips "up north" in the cooler months, that's cottage country here in Ontario and it can get darn cold really fast, this is generally not a good area to get caught in with only your T-shirt, things could get ugly in a real hurry, the other consideration obviously is weight and size, winter survival gear could be tend to be heavy as well as bulky, so probably a good idea to look around for the kind of gear that gives the most survival bang for the stowage buck and bundle it into a nice neat kit for stowage. Even in the (he he) season I'll loosely refer to as Summer, the cold may not get you but the mosquitoes and black flys will make life extremely unbearable in some of the deep bush areas if you have to spend a few days hiking out, I've seen them so thick you can hardly see through the swarms....hmmm....mabey in that situation you could glue those little guys legs to your wings and get airborne again! After all, I've heard rumours of the mosquitoes carrying away whole human beings! :o) Anyway, the moral, I guess is that's it's always a good idea to pack the approprate gear should your plane go down in an unpopulated area and mabey have to spend a few days in the elements. PS: While on the subject of outdoor survival, to survive outdoors in the winter here for any significant amount of time, you WILL need fire at some point.

True, It's a low probability that the heater core or a hose will burst and start spraying hot fluid about the cabin, but I think the significant difference here is that in a car, you would just pull into the nearest garage or side of the road and you're safe and sound. In flight, if the outside air temp is low and you have a bit of hot steam building up inside the cabin, visibility will start to become a problem due to condensation buildup even with a relatively small leak (I know this for fact because my old clunker Econoline Ford van leaked in the heater core a little bit and was a real hastle with the glass fogging heavily in the winter). Also, in the event of even a moderate leak, I would imagine you will want to contain the remaining coolant inside the motor instead of all over the cabin floor, or else your troubles may be just starting. Also, I think it would be worth while to think long and hard about the heater core placement. You don't want to put it somewhere where an object or person moving about inside the cabin could inadvertantly puncture the somewhat delicate core, perhaps it needs to be in a protective enclosure of some kind. The idea of hot water heat is very attractive though. I'll be sticking with the VW powerplant anyway, so it's not an option for me... :( Mike Sharkey X11 Development SoftArc Inc. http://www.softarc.com/~msharkey ------------------------------ Date: Mon, 26 Jan 1998 11:46:01 -0800 From: Micheal Mims Subject: Re: Re(2): KR: Cabin heat At 01:33 PM 1/26/98 -0500, you wrote: Also, I think it would be worth while to think long and hard about >the heater core placement.>>.

This setup can be used for fresh air all year round. It also doesn't route air through ducts when you aren't using it. VW makes a nifty little plastic valve for their heater coolant that is set up for a push-pull control. Those of you flying: Is the cabin sealed up enough that you need an air outlet to get fresh air to enter? Could the outlet act as the flow control? I'm a long way from building my HVAC, but I can't help thinking about it.

I question whether one is even necessary unless you are flying in MN or ND or something like that. I have been flying my bird all winter and have not installed a heat exchanger, nor do I see much need for it. Our winters are quite a bit colder up here in the mountains than anything you see anywhere near Medford. :o) The wooden boat of the KR does not wick away the heat like a spam can will. Yesterday I flew up to Blanding, Utah for lunch with an outside air temp of -1 F cruising at 10,500. I was quite comfortable wearing a light winter jacket, uninsulated light leather gloves and tennis shoes. I've been much colder in warmer temperatures flying a heated plane with an aluminum fuselage. Keep in mind that the KR was designed to be light. Adding weight will cost you dearly in climb and speed. Unless you are "Thinking Light", you will be robbing yourself of the performance your plane will be capable of. Kind of like running a horse in the Kentucky Derby with a 250# jockey. It just can't perform the way it's capable of doing.
