    --> RV-List message posted by: Jeff Point <jpoint@mindspring.com> No need to glue the foam to the floor. Cut it to fit snug and it will stay in place. You want it easily removable for when you drop hardware while working under the panel and it rolls back and under the spar... 3M77 or even better 3M90 to glue the carpet to the floor. I used one piece of carpet over each of the two outer sections, and one narrow piece for the middle foam section, and this makes the whole thing pretty easy to remove and install.

That keeps from digging in. That goes under the carpet although on top might offer some advantages. The plastic also came from Home Depot or Lowes. This is one plastic piece on each side. Ron Lee

    --> RV-List message posted by: Ron Lee <ronlee@pcisys.net> I just tried it and wanted to compare your results with info from the ADDS site. With dialup it took me perhaps 20x longer just to get the raw data than it took to get your results. Then I still had to determine the proper wind data, calculate headwind/tailwind component and decided it would be past breakfast time if I did that. So I gave up on doing it myself. Very impressive Dan Ron Lee Do not archive because the original post is still there.

I used 3M Super 77 spray on foam-to-floor. I used double-sided carpet tape (from the aviation aisle at Lowe's) to keep the carpet in place. The first year, the passenger side kept scooting forward, because regardless of how clearly briefed passengers were on how to get in, it seemed like they ALWAYS dug their heels in. At the first annual, I pulled up the old tape and replaced it, and I used almost 2x as much tape, particularly in the area where a bonehead would dig his heels in. The carpet hasn't budged since. )_( Dan RV-7 N714D (643 hours) http://www.rvproject.com

    Subject: Re: RV flooring & adhesive
    --> RV-List message posted by: Jim Oke <wjoke@shaw.ca> Dave; My solution in a RV-6A: fitted the foam between the floor angles and then fitted a sheet of 1/8 " hardboard (aka "Masonite") between the lower longerons and on top of the foam; glued the foam to the underside of the hardboard with 3M spay adhesive; next fitted and glued some lightweight indoor/outdoor carpet to the top of the hardboard. The hardboard was cut to fits in two pieces (L&R of the stock battery box) and the carpet overlaps the hardboard joint and is secured by Velcro strips. The carpet extends a few inches up the fuselage sides and is secured by more Velcro. (Velcro purchased from the aviation department at Weal-Mart). Result is a nice firm floor and the carpet doesn't wiggle around or bunch up, the floor system is removable and the bit of carpet going up the sides means that dropped pencils, etc. don't fall down in a crack and get lost. The hardboard didn't seem to ad much weight but I suppose some lightening holes could have been cut in non-critical areas. Lightweight plywood or similar would do the same job.

    Subject: Rain
    --> RV-List message posted by: "lyle" <lyleedda@telus.net> HI Rvers, Today is a day, in my country, when, if you are a pilot, you would not normally push open the hangar door, nor for that matter, drive out to the airfield. For today we have wind and rain which beats so hard that my wipers barely keep up. But then, this was such a day when, at 17, and invincible, I completed my cross country when everyone else turned back and, upon my return, was both congratulated and vilified. What the hell did I know ? it was all new to me to see rain run uphill on the windsreen, and since I only had one day off a week and had spent whole days waiting for the white light to go off on the tower, was up to the task. No radio in those days, and no need to even crane your neck to see under the wing as to what the ident for this particular ship was. All I know was that I took off on 08 and assumed to come back the same way, especially when I saw a Hurc sitting on the button of same, but NO, I found out later, they wanted me to land on 26 after skimming at 600 over the shoreline and black overcast, but the Hurc was a better indicator to me than the windsock, which I could not find anyway. And a steady green light I took to mean..OK, land !.....I mean, it was getting blacker and windier and it wouldn't get better any time soon. Pleased to get their aircraft back, the office staff told me that one Owen Lloyd in the tower would like me to call. Call, I did, and got a reaming I shall treasure always....but I was 17....a virgin still, but a warrior of the sky just the same. Which brings me back to today. For some reason, I relish a hellish day when I can sit in an airplane with wings rocking and see if I can do more than just a circuit to see if I am still at one with the elements. Besides, I now have a metal prop and that makes a difference. Well, takeoff is a non event other than the normal thrill an RV imparts, but climbing out keeps me in practice of my dance steps as I head out East and follow my beloved river. Rain is so neat to watch steaming back in rivulets as it does with the speed that an RV pulls it. Low cloud base, but the visibilty is still surprisingly good and the rivers course and sand bars with rainy day fishermen are still where they always are. What a hoot, bending this way and that with the hills still far enough away, but the tops of them and the giant Firs in mist. Before long however, things close in somewhat and after the last bend the hills rise steeply and one enters a canyon from which decisions are best wisely and quickly made, however fun and thrilling this may be, for to fly another 5 minutes this way means very bad things be lurking and even so, to get through and land at the little grass strip where gliders live may mean that one would not get home today or tomorrow, for the sake of 5 minutes more this way. This river wends its way from countless galcial streams with clear ice water to a torrent of brown, silt laden, rushing to the sea and creating the delta upon which I live. This silt can be seen for miles out into the gulf and as I turn to follow it, I now have the outflow winds from the mountains at my back and I am racing at 209 mph on the GPS back toward the barn. An RV is a very fast pony to race with, but also makes for a short entry time in the log unless you decide to run a while longer while vis is good and traffic is nowhere. I can see a white line where waves break on the shore, and freighters from Asia leave wakes a mile long behind them, and what great fun to drop down to about 300 along the shore and marvel at how now, I can actually see the speed which altitude cannot give you....no head in the cockpit now, just a very gentle suggestion to the right with two fingers and thumb, and we drop the wing and round the corner of the point, level off, climb back where we belong, race over the green pastures and call in for landing. Straight ins are a bore, and no test of skill, so a short carrier approach with speed bled off sits me down with satisfaction once again. Sliding back the canopy and I get rain in the face and when the prop stops, the only sound is banging hangar doors where some other RV builder has decided that a rainy day at the airport is better than TV at home anytime, and therefore a visit makes for a nice way to top off the day. Even if it was way too poor to fly, I would still get a boot just to sit in the cabin and watch the rain beat and listen to the wind sing her song..... Rain was meant to flow uphill sometimes.

    Subject: Re: BETA: Winds Aloft Interpolator
    --> RV-List message posted by: sportav8r@aol.com This brings up an interesting question which I am too simple to reason out for myself: at what angle does a quartering tailwind actually begin to be more help than hindrance to a pilot? A direct crosswind is not neutral from a groundspeed standpoint, since it requires a crab angle to compensate for, and reduces forward speed in the desired direction. A direct tailwind is obviously good. Variations between cross- and tail-winds produce a vector sum of good and bad effects, but at what angle does the net gain really begin? My hunch is that the "magic angle" will be 45 or 60 degrees off of a direct tailwind bearing, for reasons that have something to do with half-forgotten trig from the 11th grade. Somehow I don't think the answer varies with wind speed and true airspeed, but maybe it does. What's the answer, Dan?

    Subject: Re: BETA: Winds Aloft Interpolator
    --> RV-List message posted by: "Dan Checkoway" <dan@rvproject.com> It's not only wind angle, but wind speed and your airspeed which determine at which point a quartering tailwind becomes more of a hindrance than help. The greater your airspeed, the smaller the wind correction angle required to cancel out the crosswind component of a given quartering tailwind. It's all about vectors, baby. The short answer is: Get out the E6B and play around with it. In the meantime, the http://www.rvproject.com/wx/ wind interpolator thing is going to stay ultra-simple. GREEN=tailwind, RED=headwind, using very simple math. I think it solves 99% of the "problem" for 99% of the cases the way it is (and hey, it's free). I'll make it more sophisticated (integrating at least airspeed) at some future point in time. )_( Dan RV-7 N714D http://www.rvproject.com ----- Original Message ----- From: <sportav8r@aol.com> Subject: Re: RV-List: BETA: Winds Aloft Interpolator > --> RV-List message posted by: sportav8r@aol.com > > This brings up an interesting question which I am too simple to reason out > for myself: at what angle does a quartering tailwind actually begin to be > more help than hindrance to a pilot?

    --> RV-List message posted by: "Konrad L. Werner" <klwerner@comcast.net> To paint beautiful pictures with words craftsmithed like that! Sure sounds like Austin, doesn't it? Either way: Thank you for detailing the beauty a rainy day can have upon us, given the right perspective and frame of mind!

    Subject: Re: BETA: Winds Aloft Interpolator
    --> RV-List message posted by: "Richard E. Tasker" <retasker@optonline.net> I have attached a simple spreadsheet that will calculate what you want to know - actually two spreadsheets. Since I do not have Excel (I have Quattro Pro) I have translated it into Excel and have attached both versions. Hopefully the Excel version works - I will check it tomorrow at work. I realize the attachments will not get to the list, so if anyone else is interested, let me know and I will email it to you separately. And, yes, it is as Dan has said - vectors and the relative speeds do matter. Enjoy!
