According to what I found on the Internet, the standard is based on 100 degrees Celsius / 0 degrees Celsius, which is 32 degrees Fahrenheit / 212 degrees Fahrenheit. Which makes sense: it is commonly used for this type of ratings, because 0° is water freezing point and 100° is water boiling point.

I mounted a Carter electric fuel pump on the right fender well. I then decided that not being able to use full throttle was a bad thing and remounted the pump near the gas tank...problem solved. Electric fuel pumps push fuel, not pull fuel. in order to maintain proper fuel pressure, mount it as low as possible and as near to the fuel source as practical. Colin & Bev Rainey wrote: I have a Facet pump on my Camaro due to changing engines to a late model 3.4 which had no provision for a mechanical pump, so it necessitated use of an electric. The fuel lines were very difficult to get to in the back near the tank which is where the Facet directions said to put it. I installed the pump on the front fender which works fine as long as I don't go full throttle on the engine, which then runs the float bowl dry after about a minute because the pump cannot keep up with the volume required.Colin Scott Cable KR-2S # 735 Wright City, MO s2cable1@yahoo.com __________________________________________________ Do You Yahoo!?

I have fill in some details and have more to yet to do. Allot of detail to fill in. KRron Accomplishment is largely a matter of creating a vision and then filling in the details. With time, effort and commitment, you can accomplish whatever you make it a priority to accomplish. First, create the vision. Make it something with real, meaningful value, something that brings you true fulfillment or solves a vexing problem. Then, begin to fill in all the details. Many of the details will lead to other details, so be sure to fill in all those, too. Filling in the details is more than just thinking of what they will be. You also must bring those details to life with your actions. Depending on the scope of your accomplishment, that could take anywhere from a few minutes to several years. Stick with it for whatever amount of time it takes, and the accomplishment you envision will surely come to be. Dare to create a vision that's the very best you can imagine. Then use your time and effort to fill in all the details, and bring your dream to life. -- Ralph Marston Ronald R. Eason Sr. Pres. & CEO, KCMO Office J.R.L.

It seems I read somewhere that the KR aircraft behave a little funny with 2 people flying, like the aircraft is really only good as one seater. I think if the builder makes it too heavy or has loaded the airplane with extra equipment that 2 occupants tend to overload the thing. If anyone can clarify this, please do, as I need a reliable two seater aircraft.

I am a bout ready to order the spruce for my spars and i am going to use the new airfoil. Is there a good place beside aircraftspruce to get the wood. I don't mind milling it myself but not shure of the order list. of quanty and size. I need to get the plywood too. i live in colorado and shipping will most likely be as much as the wood. thanks jerry morris kr1 boat stage. Hi Jerry, I would direct you to Mark Lankfords site and look at the section entitled " The Gospel according to Mark". The answer to both of your questions is "yes". I did it for functionality and looks, and ease of building. With the bend at the fuselage I can lay up the whole wing and do away with the plywood rib at the stub end. I suggest you do a search on the archives before you start. If I were starting now I would order the spar stock in 1/4 inch width, for both the main and rear spar center sections. I ripped the stock they sent me with the kit, and that was a REAL PAIN. I had to order more spar stock anyway, because of the material you lose doing the ripping. I bought the 5 3/4 stock and cut it in half to save a little $. My spar is stronger, do to the fact that it is laminated. I'm getting really stoked about my project right now. On the Spruce....I live just 20 miles from Aircraft Spruce. Lucky me! I just drive there and pick up stuff "will call". I have never had a problem with them, and I would not try to save on the wood kit by cutting myself. It is a small expense of the project as a whole. I would use only aircraft quality spruce for a reputable distributer.........but that is just me. You are in for some real fun............as soon as you begin.......Jerry :) Ron Smith, Kr2ssxl http://ronsmith.myphotoalbum.com/albums.php ------------------------------ Message: 15 Date: Fri, 29 Apr 2005 09:10:24 +1000 From: "Phillip Matheson" Subject: Re: KR> Re: KR> Fuel injection in planes( LONG so BEWARE) To: "KRnet" Message-ID: <009201c54c47$76d05180$2a31ddcb@StationW2k04> Content-Type: text/plain; charset="iso-8859-1" Netters.I have been discussing the EFI with Ron Slender the owner of VW Engines Australia, His comments may be of interest to some, it is long!!!!!! Phillip, The comments made regarding fuel injection and the experience that some writers had are consistent to using a system in an auto. This may appear to be a cheaper solution it is fraught with possible problems in respect of sensors not required, altitude compensation, timing overall not to mention temperature operated at. RG are world leaders in providing EFI management for experimental aviation use. Demonstrated by our very successful RG TT 2200 and now the RG TT 2000 EFI. Our EFI runs on 2.5 Bar pressure............not 75 psi indicated. The computer controls the fuel pump and unlike an auto mechanical pump will keep on pumping as long as the engine is running. The RG engines run on MAP sensor, and head temperature for initial start enrichment. The engine is automatically leaned off according to map sensor at altitude. The computer also runs the ignition through an igniter and dual output coils. Advance and retard are controlled by the computer and the spark generated is better than a magneto could ever think about delivering through iridium spark plugs. Because the fuel map was done under a huge verity of load conditions the computer has been taught to deliver fuel and ignition according to those load demands. Optimum power delivery by precise fuel management and ignition that is what EFI is all about. Setting up for EFI properly is not cheap. You have to have a dyno to map in the engine. On air-cooled it is even more difficult because of the cooling required and the control of temperature because a tuned engine runs best at the temperature it was tuned at. Because it is easier to mount the engine in a car and to provide the cooling to it still a specially prepared car was needed to tune and map in the engine under a lot of various load conditions including acceleration rate under different loads. More expense. Not to mention the dyno time cost, fuel, long hours with highly technical personnel. One may THINK you can map in a EFI with the propeller because you are applying a load. In theory, but for that one propeller only, and at that pitch only. Change the pitch you will require a different tune. The wiring loom is a requirement so that guys cannot mess with it. Most of the aftermarket EFI specialists will tell you amateur EFI wiring almost in all cases has to be redone. That is why we include the loom ready made and tested with the engine so that this level of expertise is done to a very high standard complete with high quality terminals and crimping methods. To do all this for 1 engine is not practical unless it is a labour of love and determination to have FEI on an engine. That is why are engines are built as close as we can to the same specs so that the original tune is right for the engine. We have come a lot further now with the fact that if necessary you can data log your flight with a memory card or lap top. You can send us the data and we can make incremental changes if necessary and em mail a new program. You can have an on board 0 2 sensor but this doesn't control but reads only. You can read extra temperatures and what is really good with the new laws regarding the security of your aircraft you can unplug your computer, take it home, and NO ONE can fly your plane. Downside.......cost, yes more expensive, no carb heat, more torque and power. Some of you may say that if this fails or that fails but the same can apply to any engine and on any component. When you boil it down to reality there is always the possibility of a single point failure that will stop the engine or any engine for that matter. I keep a couple of certified engine crankshafts on hand for that reason. They say that those engines are reliable.....yes but I have 2 cranks that are cracked. When did they crack? Did they do it between pull downs? What would have happened if it had broken before the rebuild? Don't know really, but if it had broken in flight or just when you are up 100 ft it would have certainly stopped BOTH magnetos and stopped the pistons going sideways. This is experimental aviation guys where we can develop our ideas and put them into a new level of experience and the rules are to fly where you can land if necessary. Most that do abide by those rules are still alive to tell what happened. EFI..............has to be the way to go because the components are more and more reliable at 2005 manufacturing level. Our engine.........the 2000 and 2200 EFI aircooled gear drive. Currently the pick of the engines for the Typhoon and Cyclone aircraft. The choice of many aircraft builders including KR2, Europa, Sonex, Boomerang, XL Price of the engines are not as expensive as most 100 hp engines on the market and certainly more economical to maintain.

I eagerly went to the airport and installed the prop and took to the skies. The prop was a 56x64 and is now a 54x54. I have been running a three blade 52" diameter Warp Drive set at 48" pitch for the last eight hours of flight. Well today, I made a two hour flight with the re-pitched prod. To make a long story short, the performance numbers are basically the same with all three props I have tried. My conclusion is that I get 1100" climb at 100 mph and 2950 rpm. I get a cruise of 130 mph at level wide open throttle of 2950 rpm. My conclusion is that my carb is robbing me of power which this engine is capable of producing. Plain and simple, regardless of prop, I can only get 2950 max rpm in level WOT flight. The plane flies great but I really want that extra power I am being robbed of. I must get an Ellison EFS-3A and sell my Ellison EFS-2 which is actually rated for engines up to 85 HP. I still will fly the EFS-2 until I can replace it with the EFS-3A. I am having a blast flying this KR. I love landing the KR now that I have gotten the hang of it. Also, today I was taxiing to the pumps and there was a Cessna ahead of me. I pulled up and sat in the plane while two older gentlemen exited the spam can. One of the guys started over towards me and the first words out of his mouth were "when are you going to get a real airplane". Mind you, I did not know these gentlemen and I replied to him, "I have a real airplane". After the pilot finished fueling he approached and asked if that was a KR. Then the next thing he asked was "what engine is that? It sure sounds great!" With that, the conversation turned towards that pilot really talking up the KRvaircraft and his passenger basically not saying anything else. So far this plane has turned every head it has passed while on the ground. It is like a sexy lady. Men just can't take their eyes off of it. Gotta love it.....
