[RCSE] Epoxy odors
I haven't done any building in a while and am I am installing the radio in a new ship. I had to mix up a tiny batch of generic 30 minute epoxy that the local hobby shop sells so I could install the servo tray. You could smell that tiny bit of epoxy throughout my two story house. The smell wasn't overwhelming but you could still smell it. Is there an odorless epoxy on the market I can use for servo mounts and other similar applications/ I'm not talking about glassing wings or building a fuse, just simple installation jobs where a small amount of epoxy is needed.

[RCSE] Epoxy odors
I'm no chemical expert, but I'm pretty sure the catalyst is acidic and that's probably what you smell. All epoxies will have some odor to them. I would recommend doing it in the garage or workshop next time to keep the smell out of the house. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, August 25, 2006 11:16 AM To: rc Soaring Exchange Subject: [RCSE] Epoxy odors I haven't done any building in a while and am I am installing the radio in a new ship.

[RCSE] Pike Superior pulls out a squeaker over Flamingoid
MOSS held its umpteenth annual "Hanford Memorial " contest last night. It doesn't have anything to do with nuclear waste facilities, fortunately. Ed Hanford years ago laid down the challenge: "I'll bet $5 I can outfly anybody in the club after 6 p.m." So each August 24th we go out and try, and the longest single flight after 6 pm wins the trophy, which is Ed's $5 bill, framed for presentation. Lift last night was scarce, but we had about 20 club members and a few spouses on the field. Paul Wiese did 5:05 with a Pike Superior in essentially zero lift conditions. That was the mark to beat. I found a soft bubble with the Infamous Flamingoid and did 6:45, and for the first time that I can remember, I was in the lead in a club contest. Paul came back and squeaked past me with a mere 21+ minutes, finding the only real thermal of the night. The 6:45 held up for second. Todd Anderson kicked my butt at Air Hog, though. He laid down the challenge: see who can sit in a lawn chair and launch and catch their Air Hog the most times in a row. Then he proceeded to log two catches. I logged a total of zero. We ran out of daylight before we could do the Air Hog pylon, limbo or combat. Or even better the Air Hog pylon-limbo-combat. Maybe next time. Tom H. Nagel Judicium ProcuratorRecuperatio

Re: [RCSE] Foil Wing Bags joining edges
When using the foil/bubble wrap from HomeDepot there is an easy way to join the edges. Using a straight edge about 1/4 inch in from the edge, cut through one layer of foil. Then peel back the strip. You will then have some of the bubble plastic left where you peeled off the strip. Do that with the other edge you wish to join. Place the exposed plastic on the edges together and seal with a hot covering iron. My explanation is not very elegant, sorry. It's the best I can do today. Robert Samuels ...

Re: [RCSE] Foil Wing Bags
Just food for thought In the material that I use and that is used in Europe there are no bubbles as in bubble wrap. The bubbles contain Air, trapped air will continue to get warmer as the sun hits the surface, It strikes me as quite strange that a person would want to protect a high dollar Sailplane with an a low dollar item that may do significant damage in the long run. That seems parallel to the people ( some I know ) that would go to great lengths to find the cheapest and lowest costing brand of battery to place in there planes. I do not understand that thinking. Myself, and this is only my opinion, I only trust the best in my planes, considering that the least expensive kit that I have was 1200.00, with that my planes go up from there. I only trust the best in them and if it cost a little more so be it. It's a lot of money up there. -- Ken York County Soaring Lighthorse Team YCS Silence is Golden On 8/25/06, Bill Johns [EMAIL PROTECTED] wrote: On Aug 24, 2006, at 11:59 AM, Jimmy Prouty wrote: Hi!

Re: [RCSE] Foil Wing Bags
...bubbles as in bubble wrap. The bubbles contain Air, trapped air will continue to get warmer as the sun hits the surface. = Air is a pretty good insulator. The insulating properties of your fiberglass mat home insulation, the down in your sleeping bag, the foam in your cooler and the thinsulate in your ski suit are all attributable mainly to the trapped air. The solid material provides loft to maximize the volume of the trapped air, and baffling to stop the air from circulating via convection. The thermal conductivity of air is less than the majority of solid materials. The insulating ability of a most common insulation materials is more or less proportional to the ratio of empty space to solid material. Down is such an effective insulator because the quasi-fractal structure of the little branching feathers means that a small amount of solid material can puff out a lot of volume and provide very effective baffling.

[RCSE] Epoxy Odors
Sorry to disagree with you George, but you're wrong. Almost all epoxy systems consist of two parts. One is the epoxy resin, the clear, gooey, essentially odorless component. This piece contains epoxide linkages at each end of each moledule which are just waiting for something to interact with them. The other part, the catalyst, is a diamine, which is a compound with a reactive functional group at each end of each molecule. This is the component that stinks, and will turn yellow with age. Since it is a diamine, it will interact with water (you can wash the catalyst container, and yourself with soap and water, unlike the resin). The diamine is also a sensitizer to both the skin and lungs, and the reason some people develop allergic reactions to epoxy systems. Here is a little test you can do yourself. Take a few drops of the catalyst and place it in a few mL of water. It will disolve. If you try the same thing with the epoxy resin, it will just sit there. The resin requires an organic solvent (like isopropyl alcohol or acetone) to disolve, while the catalyst has both water soluble and organic soluble regions. The strong odor emanating from the epoxy system that started this thread suggests that the diamine catalyst is old, or has broken down somewhat. This tells me that the cured epoxy matrix that will result will not be as strong as if the components were fresh, since the chain lengths of the polymer (yes, that is what epoxy is) will be more varied than if the fresh components had polymerized.

[RCSE] How high?
Some time ago I put an Avocet wrist altimeter into my 3.2 meter plane and thermalled it up to where I could barely see it. The altimeter max. alt. read 2,400 ft. Recently I read a review of a small on board max. altitude recording thingee and the reviewer said he thermalled his 3 meter up to 2,300 ft. at which point he could barely see the plane. I've had a guy tell me he was able to fly his plane to over 3,500 ft. as measured by a full scale plane that was at the same altitude. (the r/c pilot was on the ground). I don't believe him. Who, among you, have measured how high you can see (fly) your 3 meter? How high were you able to go and still control the plane? Robert Samuels ...

[RCSE] How high?
Best I have been able to see with the help of three witnesses was 3,400 feet here in Louisville, the sky had a huge thunder cloud that I went up toward and that helped me see my Pike Superior, Picolario reported 3,400'. I might have been 'able' to see it higher but those standing with me, said no. This was during one of my LSF 4 one hour flights. Normally 2,100' is about the max on a thermal day. 1,700 makes it really uncomfortable. Be warned that coming down is a problem because your plane is nose in and angled down toward you , so disappears for a long period on the decent. Gordy Louisville, Mid America Soaring Champs this weekend in Lexington, part of the OVSS Series.
RE: [RCSE] How high?
Samuel, On Monday I flew my Sagitta XC (span of 14'). My Picolario said I was at 3,200'. I was at the very limits of my eyesight and I brought it down with spoilers to 2,500' for the rest of my one hour TD, LSF Level IV thermal task. I believe seeing the airplane will be totally dependent upon your sky conditions (cobalt blue being the most difficult for me); humidity/haziness; your own eyesight ability; and the span and chord of your wings. I'm sure some of the XC-boys from the West Coast will want to chime in on this one.

Re: [RCSE] How high?
I've thermaled a Boomerang combat wing to cloud base, with witnesses. A local weather service office confirmed that cloud base was over 2000' AGL on that day. Personally, I am only going to bank on it being 1000'. I can say that my vision varies. On this day it was pretty good. But, a 4 foot span combat wing is mighty small at a 1000'. I envy you guys (you know who you are) who can scape the stratosphere. Personally I'd rather fly the plane 50' in front of me than hundreds of feet above me.

Re: [RCSE] Foil Wing Bags
I've heard that a similar / suitable type of heavy-duty bubble wrap material is used to make swimming pool covers. (Jimmy Andrews) I'd be careful with that material. Its a high quality bubble wrap -- it won't tear easily -- but its designed to act like a greenhouse, letting radiant energy in from the sun and trapping the heat of the water. You'll notice this when you pull the cover off the pool, the top 6 or so of the pool can get bathtub hot. You'll also notice that you get an opaque sheet of plastic with the cover. You use this to shield the cover from the sun when its rolled up because if you don't the cover can get so hot it will actually start to melt the plastic. So, yes, the stuff's good for shielding the wing from bumps and scratches but don't leave the wing in the sun unless you're trying to cook it.

In 2004 I recorded an altitude of 3,604 with my Sapphire using a RAM altimeter. I did loose sight of it for almost a minute. Not to be outdone, Troy Lawicki flew his 2 Meter Duck to an astounding altitude of 4,077 as announced by his Picolario (witnessed by several people at our 2-Meter contest).

How high were you able to go and still control the plane?Robert, A few weeks ago at the Isle of Wight in Virginia the SBXC topped 3000 ft without any trouble and was still very visible and flyable.There were several TMSS members there and I gave an FRS radio to the crowd so they could listen. I brought it down because the weather was closing in around us and my instrument license is not current. I think it could easily be flown at 4000+ feet and still be visible. I am sure Paul Siegel has had his to at least 5000 feet. I have had the Supra at 2500 ft several times in recent months. This is about the comfortable limit, but it could be flown a bit higher with younger eyes. The 115 inch Playboy has been to 2000+ feet several times and is no problem to fly. Being basically a free flight model with an electric motor it is at home with itself. Flying it with the trim system works very well.There is a problemgetting it down. Usually a trip around to find some sink and then circle until it descends. It has no spoilers and tends to flutter the outer panels when pushed at speed.

[RCSE] How High
Hi Robert,The full scale pilot was reading his altimeter which was reading MSL (Mean Sea Level) So whatever the altitude he was reading minus your field elevation was the altitude of the sailplane.Last year at the SW Classic I did a couple of fly-overs in my RV7. The lowest was about 500' the highest was about 1500. At 1500' the planes sitting on the ground were tough to see.Interestingly, many years ago at our old field in Gilbert AZ we did some experimenting to see just how far down range we get. I was flying my Psyko and got as far away as I could and still maintain orientation. A crew on the ground drove to the area and measured just under a mile away. I was very surprised but it was a real test with real numbers.Darwin N. BarrieChandler AZ

Re: [RCSE] how high really
From: Robert Samuels [EMAIL PROTECTED] if anyone out there can give us some research based information on far a human can discern an object like a 3m sailplane I'd sure like to hear it. == Well, it depends on lighting and contrast. For resolving front-lit objects like lines on a page, various sources say that the human eye can resolve a pair of parallel lines that subtend 1 or 2 arc minutes (let's say 2 to be conservative). That means that if you had two parallel lines 10 feet apart, the best human vision could tell that there were two lines and not a single line if the pair were 17000 feet away! When you look at stars against a black sky, you can resolve smaller arcs. Some exceptionally gifted people can resolve Jupiter and one of its moons, or the North Star and its twin (there are actually 2 stars there, 18 arc-seconds apart. There's a third too, but only Hubble can see it). But seeing a wing against the sky depends not on the span, but on the chord. If the chord is 1 foot, it will subtend 2 arc-seconds at 1700 feet. The contrast is better than that of front-lit lines on a page, of course, so the eye can keep going. At 3400 feet, the 1-foot chord wing subtends 1 arc-second. Only really good eyes can see that, and it will be dependent on the brightness and character of the background. As you go on from there, you're surely getting to the limit of most people's vision. Both Babe Ruth (on his best day) and Albert Pujols have been reported to have 20/7 vision, almost 3x as acute as that of the poor middle-aged glider flyer. Perhaps if you want an altitude record, you could catch Albert on his day off to help spot the plane. RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] How high?
OK I can't resist. Mine's this high 3496 ft Boulder CO, Pike Superior. Recorded with a LoLo. I was approximately 1/2 mile down wind. So with a little trig that's about 4400 ft line of sight -Original Message- From: Robert Samuels [mailto:[EMAIL PROTECTED] Sent: Friday, August 25, 2006 3:25 PM To: soaring@airage.com Subject: [RCSE] How high? Some time ago I put an Avocet wrist altimeter into my 3.2 meter plane and thermalled it up to where I could barely see it. The altimeter max. alt. read 2,400 ft. Recently I read a review of a small on board max. altitude recording thingee and the reviewer said he thermalled his 3 meter up to 2,300 ft. at which point he could barely see the plane. I've had a guy tell me he was able to fly his plane to over 3,500 ft. as measured by a full scale plane that was at the same altitude. (the r/c pilot was on the ground). I don't believe him. Who, among you, have measured how high you can see (fly) your 3 meter? How high were you able to go and still control the plane? Robert Samuels ...

[RCSE] Help out a good cause - F3B Team Selection
Volunteers were a bit sparse at today's F3B team Trials. Jack Iafret and his faithful special assistant, Hutch, could really use some help Saturday Sunday. It's better than buying a shirt!! No experience necessary as you get it fast there, especially during the speed task - no pun intended. Your thumbs could help some good sticks. Even with a skeleton crew, Jack got 3 rounds in today. A warning, though, there is construction North of Muncie on I-69 so plan accordingly. Jim Deck RCSE-List facilities provided by Model Airplane News.
