Has anyone ever designed a model of the cozy for a flight sim? That would be the coolest thing in the world. If the flight characteristics were to be portrayed acuratley it could give a potential builder a better understanding of what it would be like to strap a cozy to thier butt and fly around. Give most people an understanding of the scale of the plane and let them know what it is like on the inside. Wanna talk about a sales presentation? I know a little bit about modeling in 3D Studio Max and would be willing to donate my time if someone has modding experience with Microsoft Flight Simulator. Just so you guys dont rake me over the coals, I know that MFS would not give the total experience of flying in a cozy. I am also not implying that it should be used for flight training. Just a demonstrator of the flight characteristics of the cozy and an example of the scale of the plane. Any thoughts or offers? TES111

No sir! Dont turn this into an anti-america, anti-armed forces thing. JEEZE Both of my brothers are in the armed forces. I guess you have to be around military personel or have some in your family to understand thier humor. Hey if it makes you feel better my brother works in supply for F-16's with the airfarce. They call their F-16's Yard Darts. I am the farthest thing from anti-american. Its was all meant in good humor. TES111

Yea; schematics is a far better word than plans guys and girls. They have to lead the public into believing that they know what the heck they are talking about. Was this kid a Navy pilot? Of course the kids mentioned in the article would all be to stupid to get the heck out of the way. What really kills me is the people that complain about living to close to the airport and its traffic. Idiots One last thing; should an arrester hook be implimented into the schematics for landings such as these?

Hmmmm. Airhead:rolleyes: He doesn't get it. I'll drop this one before I have to explain:D

No center keel with a yoke conversion. Hmmmm. Airhead?

418 lbs. Hmm? Whats the dry weight of a lycosarus?

http://www.vaircraftengines.com/ Does anyone know anything about these guys other than thier own marketing and PR releases? Were they at OSH this year?

What about the smart plugs? Don't they let you burn all types of fuels?

Will a plastic container omit a spark? Prime please correct me if I am wrong. Out with the bad and in with the good?

Thats kinda my point shender. You wouldn't do that. On a car its grounded when the nozzel touches the filler tube. Because its metal. Since you are not pumping gas before you make the initial contact there are not enough fumes to expldoe if there was a spark. A cars gas tank is preasurized. I dont think that a planes tank ever gives you that woosh sound when you unscrew the cap. There-for you still have alot of gas fumes lingering in the air space of the gas tank. One spark and Kaboom. On a cars filler tube it is filled with fresh air when you unscrew the cap and get the woosh of fresh air rushing in.

Only if your pumping gas before you put it into the filler tube. There was a neat special about this on myth busters last night.

The only reason I would purchase from marske Is that he would help design a spar that will hold the cozy's performance specs. That is the key factor and the only way that I would do it. (Same flex/strength)

I dont have it all figured out. Never meant to imply that I did. I know that I alone could never figure out this design issue. Fortunatley there are smarter people than you or I out in the aviation inndustry. Fortunatley they have made this stuff work in the past. I've been talking with a guy that makes carbon fiber rods for spar caps. He says that it is quite possible. As long as I keep the spar as stiff or maybe alittle bit stiffer than the origional spar. http://www.continuo.com/marske/carbon/carbon.htm Heres a link to his site. This stuff is quite amazing.

Those would look pretty sexy on my engine. However they look a bit small for coolant lines. http://members.aon.at/wrathall/rotary/ Check this out!!! See #72-Engine (Radiator Hoses) Thanks Again Prime:D

Dont know if you want that posted here. These are just a few that I thouth might be useful to people.

Thanks Large

(except for that one second after the implosion) I've gotta see that done atleast once before I die!

I can appreciate your concerncs but once again I think that it is possible. Not that you are saying that it is not possible. Just go to a few sail plane/Hang glider pages that utilze carbon. It is safe and there are a few that transition from glass to carbon in thier designs. "does the carbon part weigh the same but have greater strength? Or does it weigh less but have equal strength? These questions be come relevant below." My argument and fact finding is that you would want to make it the same strength but make the part weigh less. I think if the part has the same srength it would not change the properties of the aircraft just the weight. CG might be an issue but that can be worked out during the build/redesign process. "I hear similar arguments against carbon or other "alien" (again, for lack of a better term) materials on a pretty regular basis. I obviously agree with them. However, since I don't have a lot of experience on the subject, I'm interested in finding out more. Where does one find data detailing the strength of carbon fiber parts in all the aspects that are relevant here? Torsional rigidity, compression, tension, etc? " http://www.acp-composites.com/acp-ucfl.htm - Strengths & Pricing

Assuming cost where not an issue, are you saying that there is no way to plot a series of ribs for a canard? (compufoil software) Once again I'm not focusing on the spars or the wings. More specifically I am talking about parts that you would not have to modify the shape or size of. However, if you wanted to make a Carbon spar you could keep the airfoil the same and modify the notch to fit the spar that has been made. To imply that this is not possible is to say that you cant send a man to the moon even though we all know that it has infact been done. I did not want to start a pissing match here. I am not implying that you don't know what you are talking about or that you dont know how to build a canard or wing. Just simply that there is a way to design a carbon fiber part that won't be too rigid in place of the fiberglass piece that it will be replacing. Just because I design apartment buildings for a living does not mean that I know everthing about them. To say that your experince makes you knowlagable is true. But dont get so caught up in the plans that it retards your thinking outside the box. I know that I am not an expert, but do know that many people have made carbon fiber replacment parts for loads of applications. The one thing that they have stressed is that you do not need to build that part to the old specifications just because thats the way it was designed. If it is going to be stronger why not not make the part the same strength but modify the size so that it will retain the designs specifications but be even lighter? My bird is flying right @ the computer screen.

Using your lack of common sense wouldn't you make the notch the correct size? assuming you made the canard and did not buy it prefabricated. Chuck im not just speaking about a spar for the canard. Alot of the parts/mainly for skin and bulkhead applicatioins could be made the same strength but with a much lighter material such as carbon fiber. If it were the same strength it would'nt flex more , would it?

I disagree to a certain extent. If you were to use the same amount of layers in a bulkhead layup then yes a carbon fiber bulkhead is going to be stronger than an e-glass bulkhead. If you make the carbon fiber bulkhead the same "strength" but with less layers you will derive a lighter part with the same integrity. If you were to incorporate this logic to all parts would you not end up with a much lighter plane doing the exact same job? ( I stress logic ) TES111

I was going to buy plans next week. Do I still get them from Nat? TES111

Actrually marble it was two cheap pumps from an auto store vs. oem, new pump from volvo. And the reson the hoses kept failing was because the new pump had a much higher output than the old pump (due to wear on the impeller and bearing on the shaft of the old pump). The old heater hoses could not withstand the higher presure. TES111 BTW marble if you ever need a slave/helper im in atlanta and would love to help/learn alittle before I start my cozy

I totally agree large. It would seem that it would not be to expensive to go down to a muffler shop and have them bend some pipe for you. The fittings would be the difficult part right?
