I recently read in the SkyRanch Engineering Manual something to the effect "if at all possible, try to maintain cruise head temperatures below 300 degrees F for maximum engine life". Just because some manuals call out certain "expected" CHTs doesn't mean you have to be that high! I would make the argument that if it's running that cool, it's either getting too much air (and therefore cooling drag), or maybe the gauge is not quite accurate. Still, I certainly don't think 300F is too cool to worry about. > For some reason I can't post to the KR net directly since I changed > to > Hotmail .

More thorough discussions can be found in the Pilot's Handbook of Aeronautical Knowledge, and the Airplane Flying Handbook both available at any decent pilot store printed by ASA. First when adding weight aircraft speeds will go up, stall speeds, lift off speed, climb speed (to achieve the same rate of climb as solo if enough hp is available) while cruise speed typically reduces as does top speed (depending on CG & hp). A look at two aircraft that are similar will show that all things the same, the heavier plane will fly slower at the same power setting. Again, I will not re-write the book here, more can be found in the two texts I referenced, and I strongly recommend ALL who are testing read or re-read these two texts at least where aircraft performance and behavior sections are in them. A rearward CG changes the airplane's flight characteristics in known ways. What isn't known is HOW MUCH each KR example will be effected in these ways. An aft or rearward CG makes the airplane fly faster due to the supplemental lift received from the tail due to having to hold the tail up with elevator, since the weight moving back tends to lower the tail. This action allows a lower angle of attack and less drag for the available horsepower, hence flies faster. Better fuel economy, range and speed result. The downside to this CG location is that the arm, or simply the leverage the elevator has over the rest of the plane just got less. Your "prybar" for moving the tail around just got shorter by how ever many inches the CG moved to the rear. This has the effect of making the elevator less effective, since you cannot change how much it moves, or how big it is. So to get the same response from the plane requires larger inputs. How much depends on the speed, the slower the speed, the more drastic the effect is. It is possible to get slow enough that you will lose virtually all effective control of the plane and not be able to raise the tail or maintain level flight due to lack of elevator effectiveness. Remember you weigh more also so it takes more speed to maintain any flight regime even though the aft CG works to lower those speeds; a challenging paradox to test for. The most dangerous part is that when practicing (or not practicing) stalls, the aft CG tends to make the plane enter a flat spin, which in most cases is not recoverable due to how the resulting spin removes the control from the surfaces. The most uncomfortable part is that the Center of Lift is now close to the Center of Gravity which you can simulate by standing on one foot and balancing for awhile. That is why a KR with two on board gets pretty "busy". I may get flamed for this comment, but the above explanation is why I bumped my speeds in the pattern and landing up to what it takes for two on board and use them all the time. Other aircraft publish speeds that work in any flight configuration, as long as you are in the CG envelope. I was copying their pattern of publishing. Yes our KR can get slower, but my habits will allow for safe flying no matter what my load, or winds. If I wanted a bush plane I would have gotten a Kitfox or Cub. I am not bothered by using 1500 feet to land, or take off. Test carefully and with deliberate safety in mind....

To: KRnet Message-ID: <3.0.6.32.20050822091321.008368a0@pop.midwest.net> Content-Type: text/plain; charset="us-ascii" I would like to know from those that have tried. Due to the banana boat the fire wall and longerons are not perpendicular. If I use the smart level and use the firewall as my main reference what will it do to the flight stance of the plane? >Steven Phillabaum +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ This post is long so if you're not interested, hit delete now........... You will get as many opinions on this as there are builders. All will claim to be easy and accurate. Without saying my process is the only way to go, I'll let you decide. It worked for me and my KR flys without any fixed trim tabs and both aileron trail edges matching the wing trail edge. I attribute a very, very, very slight right wing heavy condition at cruise in my KR to me getting the trail edge rib on one side of the center section wrong. That can be eliminated by using the "Langford" method on the ribs. This process will work with either wing and whatever incidence you decide to go with. Just mark your ribs accordingly. Consider the important points ( I think ) of engine thrust line, wing incidence, and horz stab incidence to having a nice flying KR. My opinion is that the fuselage being off by a degree or so is much less critical than these items. I recommend using the firewall to level. It won't get crowded until much later in the building process and then you can use a short ( 6 inch ) level somewhere on the firewall to set the fuselage to level for W&B. Top or bottom of the firewall will do with only 3 inches or so of the level on the firewall. Do yourself a favor. Buy a "SmartLevel" (digital level ) now as you can use it to build/rig your KR and set control surface deflection later in the process. As Mark suggested, a good bubble level can be very accurate. I used two bubble levels to set up my KR and found it to be within 1/10 of one degee when checking later with the digital level. I started this process after I had my wing attach fittings installed on the spar with dihedral set on the work table. You then remove one set of fittings to install the spar as suggested in the plans. A complete "dry fit" run of this process before any epoxy is mixed will insure no surprises later. I'm speaking of a dry run of the center section only here, that being the forward spar, ribs, and rear spar. Start by leveling the fuselage using the firewall and place a level "across" the top longerons to level side to side. Insert the forward spar and level side to side and check distance from tip to tip to the tail for 90 degrees to the centerline of fuselage and spar is parallel to firewall (vertical). When you're satisified, glue the forward spar in place. Determine what wing incidence you want, draw all markings on the 48" ribs (cord line, spars ) and cut the 48" ribs using the "Langford method " with the "humps" at the spar locations. Cut out the spar holes and mount the ribs on the center section spar. Double check the incidence (using cord line and SmartLevel) and glue the ribs in place. If you have any twist in your forward spar (as I did) you can adjust your ribs using the digital level and cord line to compensate. Now use the rear spar cutouts to locate the rear spar and glue in place. Make sure you remove the "humps" on the ribs before sanding the wings! :-) Setting the horizontal stab is a matter of leveling the fuselage again (using the firewall) and place a SmartLevel across the horz stab spars, set the incidence you want, and glue in place. I set mine to level using a bubble level and probably should have been set to 1/2 to 3/4 degee down using a digital level. I'm using the RAF48 set to 3.5 degrees, 3 degree washout, with a 24 inch fuselage stretch. Go to Langford's sit to get an indepth read on this subject. I build my outer wing panels one at a time and that worked out also using the "SmartLevel". Level the fuselage (firewall) and attach the outer forward spar. Attach the 36" rib so it will pivot on the spar such as a nail through the rib to the end of the spar. Use the digital level and cord line on the rib to set the incidence you want with washout, jig and attach the rear spar, and start building. If each step in this process is done correctly, you will end up with a perfectly rigged KR. No math, no water levels, who cares about the banana boat, etc. I was able to build/rig my entire project as a one man operation. The only help I used was to cut/taper the outer spar caps and that probably could have been done solo also.

My Revmaster uses J wires held in the head with allen screws. These tend to read 50 degrees F lower than wires below the spark plugs. Also, you might want to google the web for info on the j temp probes. Depending on your method of running the sensor wire from the engine to the gage, you can end up with much lower temp readings.

On this subject, I painted my first KR with Dupont Centari and was going to do the same on this one, but it was $150 per gallon. The PPG Omni brand was $40 plus hardener. The reason I say was is because as the price of oil goes up, so does the price of paint.

Follow the procedure as I understanding. 1. Sending the foam. 2. Cover/squeegee over the foam with slurry (Micro + epoxy) 3. Cover the wet slurry with glass cloth. 4. Cover over the glass cloth with pure epoxy and squeegee off any excess epoxy. 5. Wait two day, when all the slurry/epoxy is dry. 6. Sending the surface area. 7. Use macro slurry to fill in unsmooth area. My question: A. This process is correct? If not please correct me. B. This process suitable to all area with foam like: Wings, Horizontal stabilizer, Elevator, Vertical stab and so on? C. Within the "Book Plan" of the KR-2 mentioned, Micro beads is totally non structural. How this instruction related to the cover of the wings foam with Micro beads and then covers with glass cloth? Waiting to confirmation or correction.

I have added the following steps in my practice. 2a. I allow the slurry to cure. 2b. Sand and fill voids, sand and smooth out surfaces to near final finish. 4a.Add peal-ply cloth over the fiberglass. If you want to have a superior finish these my help. You will eventually find what is best for your taste after a few tries.

I believe that the "Grove" type, single piece aluminum gear is the easiest to install although it is a bit more expensive and a little bit more heavy that the Diehl. I see nothing wrong with the RAF48, but if I were to do it again, which I won't, I might try the new wing, and that would only be if the spars were not already installed.

Also, I too found it odd that a CHT could possibly be too cool unless it is a sign that you are dumping pure gas into the cylinder. See you in Mt.

Still, I certainly don't think 300F is too cool to worry about. No clue on that one, although Hotmail is notoriously unreliable... ------------------------------ Message: 23 Date: Mon, 22 Aug 2005 16:41:00 -0500 From: "Robert L.

Of course this depends on the trim pattern. You can see mine on the KR year book, http://www.krnet.org/krnet_yearbook.htm about the 20th or 21st down.
