The RC model airplane and helicopter nuts are already using electronic piezo (sp?) gyro stabilizers to dampen pitch, yaw and roll. These things are compact, light and adjustable for rate sensitivity. Just check one of the radio control model airplane magazines and look at the ads; or search www for piezo gyros. These things can be used to provide switching signals to servo powered trim tabs or anti-servo tabs. Thought your idea might be a great one for an anti-servo tab on the elevator to dampen pitch.

Rather than turning the engine backwards, you would turn the engine around and drive off the other end where the engine was designed to drive. That also has the effect of changing the prop rotation to the same as the Continental/Lycoming engines.

Warron > No doubt that a spring preload would help decrease the sensativity of the plane and keep the elevator from wandering so much (like the aerobatic map folding). That's why the GlasAirs are build with a centering spring on the elevator. I have given some serious consideration to adding centering springs to my KR for the same reason. It goes along ways towards addressing the sensativity problem which is mostly a lack of feel from the elevator. The springs add some feel to it. I haven't done it because after so many hours, I don't even give the sensativity a second thought the vast majority of the time. However, It isn't a cure all and doesn't completely address the pitch stability problem which is due to an undersized horizontal stab. That is why the GlasAirs extended the fuselage, then went to a 10' wide horizontal stab. Although the GlasAir 1 stability is much better than my KR, it is no where near stabile as a Super 2S model. An improvement to the stability and sensativity would go along ways in avoiding first flight accidents and incidents for the KR line. Before you poo poo others flying experience with "high performance airplanes", we had all better start comparing log books. :o) Jeff Scott - Los Alamos, NM mailto:jscott.pilot@juno.com See N1213W construction and first flight at http://www.thuntek.net/~jeb/krjeff.htm ___________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

KRRon ---------------------------------------------------------------------- Subject: Re: horizontal stab From: Michael Taglieri Date: Tue, 18 May 1999 21:45:20 EDT X-Message-Number: 18 It sounds to me that what he's describing is a "downspring," a time-tested improver of stability (although it has nothing to do with balancing the elevator). A downspring pulls the stick forward with a slight force at all times, so when the airspeed drops, the downspring will "help" the elevator go down and makes the nose drop. Therefore, to some extent, it mimics the effect of a larger tail-volume without the drag increase of a larger tail. That's my Reader's Digest version. They're discussed at greater length in "Flight Testing Homebuilt Aircraft."

Those being Stability and Sensitivity. The stability of an airplane reffers to the inherent ability of the airplane to seek equilibrium. For the sake of simplicity, picture an airplane flying along straight and level. If you pull back on the stick and let go, a stable airplane will oscillate - first up, then down, then up again and so on, with each oscillation getting smaller and smaller until the airplane is again flying straight and true (equilibrium is reached.) A KR that is not stable will continue to oscillate, or worse, each oscillation will be larger then the preceeding one - therefore, equilibrium is never reached, and the KR is inherently unstable. Volumes have been written on the subject of stability - well beyond the scope of this email, but let me assure you - balancing the elevator has no effect on this, and I don't care how many hours you have - this doesn't change - it's a function of the airplane. Keep in mind, that this is where the limits of the CG are dervied from - too far forward or aft, and the airplane becomes unstable. Sensitivity, on the other hand, is very much a pilot-based phenomina. The sensitivity of an airplane takes many, many things into account, but for the sake of simplicity in this discussion, let's just say that it is the amount you have to move the stick to get a reaction out of the airplane - after all, that is how the pilot measures (feels) it. Just for the point of illustration, let's examine a couple of the many things that effect sensitivity. 1. Elevator Size. In an airplane that is known to be very sensitive, the first gut reaction is to make the elevator size smaller. Sure, it will now take more stick to get the airplane to do the same thing, but the pressure on the stick that the pilot feels for a given travel of that stick will be much less. Most texts reffer to the stick presures when discussing sensitivity, and by using this definition - you just made the airplane MORE sensitive. The danger in this is that at low speeds (as in landing,) you have to make sure that there is enough airflow over the elevator to keep it functioning. If you go with a larger elevator, then the stick forces are increased per degree of elevator change. 2. Moment arm. The further the tail is away from the CG the more it must move vertically to impart the same change in angle. I'm not going to go into depth on this - it's pretty inuitive, but remember that changing the moment arm also effects the stability of the system. 3. Gearing. By changing the gearing of the connections from the stick to the elevator you can effect sensitivity. A wider bellcrank on the stick to a smaller bellcrank on the elevator will mean more stick travel per degree change of the elevator - Sensitivity is changed. Remember here, that you still need to have adequate travel of the elevator at low air speeds. This can become limited very easily. 4. Springs and things. You can artificially create a less sensitive system by using springs to change the stick pressures. If I was building a "RR" tail, I think I would go this route. But, you are complicating the system. More parts to fail (and failure could potentially be a BAD thing) and more things to adjust as the spring tension changes over time. But it is functional. The list goes on and on - I don't to bore anybody here so we'll call it enough already. But notice that I didn't include balancing the tail. Yeah, it's on the list but WAY, WAY down there. The effects of sensitvity changes due to a balanced system are insignificant compared to the things listed above. But should you balance the elevator? - YOU BETCHA! Balancing the elevator is the foremost thing that you can do to decrease the chances for flutter development. In any airplane like this where velocites of 200 mph are not unreasonable - balancing the control surfaces should not even be an option - it should be done - period, end. I'm trying very hard to play nice.

My response to your post was a bit on the as*holish side but I couldn't help myself because I found it kinda funny. (mostly because of the apparent confusion of stability and sensitivity and I can be a as*hole now and then) As far as "non-flying persons" well I think all three of us fly regularly and I know at least one of us has a few hours in various high performance aircraft. The resource on the KRNet is actually quite awesome considering the scope of experience. Think about it, we have engineers, structural, chemical, and aerospace types. We have real test pilots, we have mid to high time pilots with experience in a multitude of aircraft. We have machinist, mechanics, computer engineers, and yes we have doctors! :o) Best of all we have real KR pilots. I guess what I am trying to say here is although most of us don't know it ALL (I am working on it) we do have something to share and for the most part when we speak we are NOT talking out of our ass. Not that its the word of God either mind you. That being said I agree with Jeff in that the KR is a pitch sensitive airplane but for someone with a little experience you should be able to get used to it and fly it within your limits on a daily basis. If not you should probably turn your certificate back over to the FAA. But lets not forget the one thing we are trying like hell to prevent. Those all to familiar "first flight mishaps" due to the thing being a little more sensitive than say and F86 Saber Jet. Your spring idea helps in the sensitivity department by adding feel or friction to the controls but it does NOTHING for stability and that being the reason for my response to your post. Stability is that thing that will keep you from recovering from a stall or a spin. Sensitivity is that thing that will cause you to enter a stall or a spin too easily because of the lack of feel. I honestly believe that vary few KR flyers have ventured too far into the stability thing while flying. If you have you would know it by the strange way the nose keeps pitching up and down no matter what you do to try and stop it. That would be pushing the envelope a little too far.

I wanted to know if there would be any problems strenght- wise using this finer weave cloth instead of the 18 x 18 cloth. It may eliminate most of the pinholes.

(wing levelers) >> For wing levelers, yaw dampers and pitch stabilizers gyros are more useful. Accelerometers cannot differentiate between forces generated due to acceleration and gravitational force. There was a thread about a year back when someone talked about using a model airplane gyro for pitch stabilization. It may be a good idea to have a sort of stabilizer so the pilot can take his/her hande from the stick for extended period of time. Haris Closed rear center spar today.
