We are in indiana with a GSHP system using copper tubing in the ground and R122 as the heat exchange medium. Its a very good system now though the first compressor we had blew up not long after installation. It was fixed and we've had no issues since. Our house is also all electric and...

If you've never flown one it will be tough to justify anything. If you have flown one you'll agree that they are really nice and comfy. They're great flyers too. There are some mods to speed them up a little but as noted, they are slow for the power. On the other hand it is wonderful to carry...

Downforce is lift in the other direction. Vortex generators can make a difference even at low speed as they help airflow remain attached just like on planes. It can allow more downforce by reducing lift or by allowing airflow over areas that would normally be in turbulence. We used VGs on...

I worked for a factory that built sailplanes and for a mechanic who did general aviation maintenence. After 30 months I got signoffs from the guy who ran each business and took the writtens...passed and took the practical. If you have good mechanical skills and pay attention you can go that way...

Is that the owls head area? Frank

I was skiing at Santa Fe in the 70's.....definitely not new. It was old then. They added some really nice lifts in the 80s and have a very nice area for newbies. Angel fire is not bad and they also have some good slopes for newbies but its a lot further from ABQ....not sure where you're...

I guess what he meant was that he didn't need a huge ship to go out into the ocean and fish out the shells of the solid rocket boosters. His rocket returned home where no doubt it will need overhaul too but the cost savings should be huge. Wonder what just the fuel cost is to go 100 miles...

Weight doesn't affect the glide ratio except in the extremes. It changes the speed at which the best glide ratio can be obtained and that is a key for the high performance glider types. Note that Brian said his best L/D went from 50 to 60 knots. This gets you more distance over the ground in the...

When I was going down every weekend in the 80's and 90's the lake was full and pretty big. I heard they lost their water rights lawsuit to mexico and texas though and had to dump a lot of water. Caballo is now a mudpit if even that. On the other hand I watched a couple float planes land on the...

I went to military school....but it was because I wanted to. In 3 years of high school there I saw about 50% of the kids who were sent for control/attitude issues fail out or get tossed. The remaining 50% seemed to actually learn something worthwhile. I think most of what we learned was that mom...

I've seen some seriously overheated rings that would bend like solder. The pistons looked like hell and so did the cylinders. Not a common thing however from what I've seen. Frank

They can also have straight pipe threads vs tapered pipe threads...... at least we don't have whitworth and BSP to deal with....normally. Frank

I set mine vertical in the hanger so no one walks into it.. hard to see in the dark and not much room between nose and door. Lots of good reasons to do it and not to do it.....depends on the situation more than the plane and prop. Frank

looks more like Switzerland than the midwest.....sounds like it too. Might be Germany too. Sounds more like Deutsch than Schweizerdeutsch though..... Frank

I'm still trying to figure out why the ecofreaks have such a hard on for diesels. They're more efficient then gas and produce less emissions per gallon and even less per mile. They whine about carbon emissions then complain that diesels capture most carbon as a solid.....soot. Soot is now the...

They sold a pretty extensive machinegun collection a year or so back. That brought in a fairly good amount......at least what most of us would consider a fairly good amount. Probably not a drop in the bucket for them..... Frank

I was standing in the lobby of a hotel in Dresden Germany watching the second plane hit the towers. Along with the others standing there we were trying to figure out what the hell was going on. We were also wondering if we were going to be allowed to come home. Took us two weeks to get home and...

Adding the nose wheel changes the flight and landing characteristics but doesn't help the cabin comfort. You lose the offroad advantage of the plane while retaining the the cabin. You might as well buy a 235 cherokee. You don't lose the landing characteristics but you gain a nice comfy...

I'm kind of partial to the FW190-D9. Father of my childhood sweetheart flew them in russia. .... they were fast and sporty too. Frank

I've seen it from the rocks and from the top of the lighthouse but never from the air. Nice pic. Thanks Frank
