Hi Larry, You might want to check on the GRT yahoo group to see if anyone wants to sell theirs - most of the GRT EFIS systems show the trim on the EFIS. Just as an aside, do you actually use the trim indicators very much while flying, or is it just to set the trim at takeoff? -- Mickey Coggins http://www.rv8.ch/ #82007 finishing do not archive ________________________________ Message 2 _____________________________________ Time: 04:05:41 AM PST US From: "Ron Schreck" Subject: RV-List: How to add 15kt to cruise speed by adding weight --> RV-List message posted by: "Ron Schreck" I like both Dan and Rick's explanations and throw in a specific example of a very unstable airplane to illustrate the aft CG phenomnon. I used to fly an airplane that had the CG well aft of the center of lift (CL). In this configuration the tail plane needed to produce lift in order to keep the aircraft level. The advantage of this configuration was that both the wing and tail plane created lift in most every flight regime rather than the wing producing lift and the tail plane producing down force as for a conventionally balance aircraft. This made for some extremely tight turns and rapid response to control inputs but also made the aircraft impossible to control by the most experienced pilots. Solution: Put a computer in charge of stability and let the pilot input his desires through an electronic input to the computer. Thus you have fly-by-wire technology and the only way to control an F-16. Ron Schreck RV-8 "Miss Izzy" Gold Hill Airpark, NC --> RV-List message posted by: "Rick McCraw" I like Dan's explanation, but will add a bit more. Specifically, we require the CG to be forward of the center of lift (CL) in order to have a stable aircraft (and one whose nose drops when the wing is stalled). The closer the CG gets to the CL, the less induced drag, but the less stable the plane will be. If the CG should go aft of the CL, all bets are off in terms of controllability. Another e-mail commented on Bonanzas and how their CG moves with fuel burn. Whether the CG moves aft with fuel burn should depend on the CG of the tank and its fuel relative to the CG of the plane. I fly an A-36 Bonanza, and when weight is up (hence, realistically, with a CG farther aft than when lightly loaded), I have indeed noticed greater pitch sensitivity after a long flight. When I plan flights at higher weights, I check my loading by calculating CG for zero fuel, just to be on the safe side. For extra margin), I try to land with fuller tanks, too.

To get stability (AKA, hard to flare), you move the CG forward. Think Lawn Dart. In this mode, the tail actually pulls down, not up. This results in the wing needing to produce more lift (weight + the tails negative lift so that total lift = weight). If you move the CG back, you have less and less down-lift on the tail, letting the wing work less, thus getting less induced drag. Faster. A heavier airplane, with the same CG, should fly slower than the same plane, same CG, when it is lighter. The reason is the heavier airplane must have a higher angle of attack to produce the needed additional lift. That means more induced drag. The CG limits are set to give reasonable handling. The forward CG is limited by the ability to flare. The Aft CG is limited by the need for positive stability. If we moved the CG back to where the tail was lifting, we would have no stability. In the normal range, as the plane slows from the trimmed AS, the wing and the tail both lose some lift. But the tail is now lifting less in the downward direction, letting the nose fall down a bit and resume the trimmed AS. If we move too far back, we lose the stability feature making the airplane difficult or impossible to fly. Rule of thumb: smooth air, load for aft CG (within limits). Rough air, keep a more forward CG. So your data does make sense. (But the faster/heavier combination is probably just due to aft CG.)

The weight should be properly secured. You don't want it coming loose during turbulence or an off-field landing and hitting you in the back of the head. 2. Adding weight aft will increase the moment of inertia on the yaw axis, and this will probably degrade the spin characteristics. I.e the results from any spin testing you did without that weight are now invalid.

At 5,500 ft, I have measured 9.2 to 9.4 gph using the 'fly it half an hour on one tank then see how much it takes to refill the tank' method. To get the aft CG, I added weight to a fixture I built for the aft baggage shelf and added a 50 lb sand bag to the aft seat. Total 142 lb. I can refly the forward CG test at the higher altitude & will report the result. But it will probably be a while because I'm flying the RV to Brady TX for paint. I'll have to leave it there about a month. Of course, I'll put everything in the aft baggage compartment for the flight!

These are all just opinions about POSSIBLE problems and solutions. If you don't agree, delete or pass up the post. No one wants to know how much more you know than the poster. All posts, including this one by the way, fall into the wheat and chaff category: take what you can use and throw the rest away. You can do what you want to your airplane: they are experimental. This is ALL good information, even if it isn't what you would do. As for Wheeler, his skin is WAY thicker than that. He's cool. No need to worry about insulting him off the list.

I'm going to check the weight and balance after it's done with just me, and then with my bag of salt in the back and see where she sits in the envelope. Then I'm gonna fly her both configurations and see if I can see a speed difference.

WAY to much room in the front seat of an -8 ?. You will then absolutely hate any Rocket 'cause it has lots more of the same. Where do you put your arms in turbulence ??, With one hand on the stick & the other on engine controls AND properly belted in the wide open space so as to not turn shoulders black & blue banging them off the interior hard parts of a too tight cockpit. But then again as one ages things can get difficult, like getting in & out of my LT-1 C-4. BUT that's just IMNSHO (In My Not So Humble Opinion). 8*) KABONG HRII N561FS aka RV-4 on steroids. ----- Original Message ----- From: "Michael" Sent: Wednesday, May 31, 2006 9:47 AM Subject: RV-List: Front seat, back seat, when I'm flying in my plane > --> RV-List message posted by: "Michael" > >>Simple, get an RV-4, RV-8 or Harmon Rocket II.

Michael I was once teaching a new aviator (3 to 5 hours) Helicopter primary flight, demonstrating setteling with power. When the Big Scielence (engine failure) over came us. It being a demonstration only manuver with considerable altitude, I was already on the controls, entered autorotation, made all the radio calls, and setteled back to enjoy the quiet. The scielense was almost immediatly broken when the student pilot screamed in quit an aggitated tone," What do I do, What do I do." My reply," Grab that switch and recycle the rotating beacon at three second intervals." After we were back at the breafing room, I could still see the dismay covering the student's face. I ask," What's the matter kid?" He said," Sir' I just can't understand what recycle the rotation beacon.........." Interupting him, I explaned that it occupied his mind and kept his hands clear of the controls while I was taking care of bussiness. A big smile errased the look of pusselment from his face,I winked, and he resumed telling his fellow student aviators about his hair raising event. Now from all this you can conclude that almost any action you take that doesn't make a bad situation worse has a good chance of improving it. On this list you pick out the salutions you like and file the rest away for later referance but,you never dismiss any or alienate anyone that offered them with good intention, because this is an inviorment where you never want to run out of salutions.
