TETRA Rookie 20 Refreshment

Refreshment of TETRA Rookie 20 is completed, motor replacement from OS 32 F to ENYA SS 35 and fixed nose gear to steerable one. No movement of CG occurred as a matter of fact. Though, 35 motor might be recommended that too much for the 20 class trainer, just overpowered leading to an unable woman, F3A pattern maneuver on windy condition requires unbalanced motor power.
Probably, precise motor controlling technique might be obliged to keep stable flight.

I wanna ask to myself that do I do my works more conveniently, more quickly!
Do I make myself in a comfortably warm spring bathing?
A trifle person like me has a tendency to lead a life with eating full, oversleeping and  wasting time, especially a dragonfly living in a Paradise, in Japan country with no aggressive fighting, no starving, no dangerous circumstances even in the middle of the night.
Situated in Far West US Strategy Front as Japan country is, we are keeping a peaceful daily lives here, is this phenomena brought just because of Japanese Peace Constitution? Or, because of US military air bases scattered all over Japanese land, 84 in number?
Should we Japanese nation recognize the fact and truth that the occupation by US has been long lasting since the end of WW2?
Remember that a cleared up blue sky also exists in a biggest Typhoon Core Center!

Throttle modification for YS system

The most important requirement is often lost to modify ordinary motor to YS fuel pressurized regulating system. Orifice effect in the throat while low speed operation should be removed to obtain stable rotation.
In order to do that, lower part of throttle valve must be opened freely when drum type throttle construction is invited, otherwise YS system would not demonstrate it's performance enough. So, the throttle valve must accept some irreversible modification, no return to natural aspiration.

Replacement parts

ENYA SS 35 was disassembled only on the front housing portion for the purpose of setting up pressure nipple, in combination with YS fuel pressure regulating system.
The bearings for main crank shaft supporting is #6901 and for front is R4A inch size promptly. The capacity of their road is adequate design for this 35 motor.
Careful scaling was performed to establish the most suitable pressure withdrawing timing, nipple position and crank shaft engraving point both are very important requirement for proper performance of the regulator, between 105 and 160 degree value ATDC is the key to success.
As for an original carburetor, 6,5 mm throat diameter is designed for the use under natural aspiration condition, but judging from an actual scaling the port gas way in the crank shaft, 7,5 mm diameter, more 1 mm wider throat wold be effective for the ultimate performance if operated under fuel pressurized condition.
Consequently, ENYA GM type carburetor with 7 mm diameter throat is invited for the upper purpose. The mechanical construction of GM carburetor makes it possible to adjust mixture as to attain the best low rotational condition not only natural aspiration but fuel pressurized conditions.
The reputation of SS 35 among the modelers is not so favorable because of narrower in take gas way in the crank shaft, but my modification would thoroughly wipe out such kind of rumor, YS fuel pressurized regulating system is the only way to do that.

Rookie 20 maintenance

Long awaited modification is not on the way on TETRA Lookie 20 trainer airplane.
Because the surface condition of flying place is flat well, fully plated with dubber mat, too much distance the airplane goes without stopping.
So, steering function on the nose gear is indispensable at all. This is why I made up my mind to apply TETRA Nose Gear S type on Lookie 20 in stead of fixed one.
The performance of OS 32 F could be understood enough in combination with YS pressurized fuel regulating system, so the motor would be exchanged into ENYA SS 35 that is light enough to meet with OS 32 F. A pressure nipple to withdraw pressures for pressure signal activating the regulator in adequate timing.
Indirect mounting mechanism should be fabricated again utilizing L shape cross section Aluminum Alloy material by myself.
These modifications are very simple as described, but they are relatively complicated and time consuming task.
It became cold outside, so now is the time to be spent for working table tasks rather than going out for flight.

ASO 88th Regular Concert in Fukushima OSAKA

We enjoyed utmost Classic Concert this evening, Ashiya Symphony Orchestra 88th Regular Concert, also ASO 50th anniversary special Concert was held at Fukushima The Symphony Hall OSAKA. And it was successfully performed as usual under the conductor Mr. Kazusi Yamashita. Additionally, beautiful vocal encore was done for the sake of the spirit of disaster in Tohoku area a few years ago, actually the made a concert tour at Ishinomaki on 3ird in November, at Sennan Art and Culture Center on 4th November, and today.

We are longing for the next ASO Concert next Spring.

Accidental affair

I was disappointed to know that OS does not supply the part of 7DV carburetor spray bar any longer because of old model. As I have been suffering from stuck feeling at the fuel squeezing construction from new condition. This strange phenomena should be caused by some low manufacturing(poor quality control) by the manufacturer. So, I tried to establish the centrality of spray bar inclination by inserting metal rod inside, applied stress damaged splay bar slit portion by chance and incredible breakage happened along through the slit miserably as a matter of fact, Oh my God!  Fuel squeezing mechanism in 7DV carburetor has lost completely, how come?
The carburetor should be brought to OS service front asking any countermeasure before I did poor action on it, then they must have done well with it as usual.
This destroyed part had been thrown away for long time because of the reason.
Just I imagined the way to rescue this lonely one by myself imitating the fuel passing ways in YS 60 FR motor, yes, engrave the sharp triangle passing way on the throttle valve and carburetor body inside.
Deeper consideration should lead me to do that because have I a good control in front of me.
Several precise modifications must be required on the way of machining procedure, but I'll do that once the idea comes in to my mind.
Wanna I fulfill my ambition, it is interesting, don't you think?
Of course OS 61 RF rear exhaust port type motor would be operated in combination with YS fuel pressurizing regulator system.
Reporting on this interesting trial attempt would be done later.

Super Beetle brake maintenance

As I felt some strange feel at the state just before stop, inspected I front wheels of
 Super Beetle by lifting up, then unacceptable rotational resistance was observed in right side wheel, so to speak stuck feeling.
Following the natural countermeasure for this inconvenience, the brake drum was removed, no problem was found out in wheel bearings, inner and outer.
Careful checking on the operative cylinder, the sliding pusher for the trailing side was cohesively stuck. This kind of banish like material might have come from gradual leak of brake fluid or denaturing of silicon grease applied at assembling stage.
Removing all the banish there and reassembling the construction re-obtained the natural function again.
Whenever we start the brake maintenance work, some dust sheet under the wheel must be prepared, otherwise, the pit floor would be spoiled as shown in the picture.
I felt the necessity to check brake construction periodically, the maintenance sheet by the constructors is not prepared unreasonably.

YS pressurized fuel regulating system

Though the performance and stability in actual use is already proved by the manufacturer, their regulator system is available or not on another motors by different constructors except Yamada under the natural aspirating carburetor fuel pressurized condition. According to the opinion(probably scientifically proved by actual measurement by the company) The pressure value of the first stage compression in 2 cycle motor crank case is the same no matter how the displacement value might be different, meaning that the first stage pressure value is the same in the smaller motor as 10 cc motor. We might regard it smaller in a smaller motor, but they are the same value, even in L.M. Cox 010 cu inch motor. So, my curiosity to prove the fact if it is possible or not, to apply the system on another motors, it is a simple but long lasting reason why I have been advocating on this point.

The way of experiment
The pressure nipple was set on the front part of crank case for the purpose to pull out the first stage presser that compress the fuel tank to supply pressurized fuel to the carburetor and controlling the fuel amount adequately and supply stable amount according to the motor speed under some changeable burdening condition in the maneuver scenarios. YS regulator is mounted on somewhere nearby the motor independently.

The requirement for operating YS regulator system in steady state
No pressure leak in fuel line and pressure line including one way valve and fuel strainer and regulator such as small grain dust or fiber material from the textile.
Pressure nipple(pressure extracting point and duration) should be properly between 105 degree and 160 degree ATDC. The pressure extraction angle value is very important to obtain the most effective controlling avoiding pressure fluctuation caused by fundamental 2 cycle piston valve construction. The stable pressure supply contributes not only to the tank burdening position, most of the case it is near CG point but also to the linear carburetor action in combination with the diaphragm regulator system. Requirement of the carburetor YS fuel pressure regulator does not have the capability to control the fuel amount at the lowest throttle position. The diaphragm control is not so linearly at the throttle closest position.
Consequently, it should be controlled by carburetor construction by means of fuel squeezing mechanism such as an additional opposing needle or slit closing spray bar designing. Air through controlling screw is not always necessary here. ENYA G-type carburetor is available if the fuel way should be closed utmost following the groove engraved on the throttle valve drum surface.

Gnathologisches instrument

Gnathologisches Instrument
Gnathologisches Instrument Bedauerlicherweise geschah eine elende Angelegenheit.
Ein kostbares und teures articulater, Charles E. Stuart entworfenes völlig justierbares Gnathologic-Gerät im zahnmedizinischen Feld verschwand im Museum, das Fall zeigt.
Ich fand es zufällig in der Lagerstätte im Zustand des Verlustes der Schneidezahnführung und des abgetrennten oberen Gipsverbandes.
Als ich fragte, wo es sich um den Chef des Zeuges handelt, antwortete er, dass es irgendwo ist und er es später suchen würde, wie lange ich auch den ganzen Tag warten könnte, die Zeit, den Ort zu schließen, er bereitete sich darauf vor, nach Hause zu kommen. zu ihm, dann bring es mir morgen.
Wahrscheinlich dachte er widerstrebend, er bediente die gebogene und verzerrte Führungsnadel mit der Entschuldigung für den Fehler, der von einem der Dinge verursacht worden war. Aber er hat nie erklärt, wer es mit Namen getan hat.
Fallunfall war der Grund, den Artikulator zu verbergen!
Laien oder Laien verursachen manchmal solche Fehler, weil die oberen und unteren Bögen in Arcon-articulater getrennt sind, nicht im Scharnierbereich.
Er hat sich entschlossen, die Strafe durch eine gemeinsame und multiple Verantwortung zu bedecken, es ist nichts anderes als eine japanische Denkweise, als ob er eine Person mit warmem und sanftem Geist wäre.
Er versteckt die Beweise für immer oder bis es offensichtlich wird?
Auf der anderen Seite habe ich eine andere Art zu betrachten, dass ich und betone den Punkt, die Bedeutung ist, wie wir den Unfall entgegenwirken können, reparieren oder ein neues Teil an den Hersteller bestellen.
Sich zu verstecken oder sich anzuziehen, als wäre nichts geschehen, ist nicht der richtige und faire Weg. Sorgen in seinem Kopf ließen ihn das tun?
Ich missachte oder bestrafe niemals irgendeinen Fehler, wenn es nicht absichtlich geschehen wäre.
Die Wichtigkeit ist die Gegenmaßnahme unmittelbar nach dem Unfall!
Wir sollten gemeinsam über das Problem nachdenken, wie das geht, es hat nichts mit der Bestrafung einer bestimmten Person zu tun.
Ich muss das mit einer sanften Ablenkung, etwas schwierig, einer anderen Generation von Jungen und Mädchen beibringen.
Erinnert an meine Vergangenheit, bestrafte mich mein Chef im Institut der Graduierten-Universität am meisten, wenn ich nicht allein, sondern allein getan worden wäre, ich habe die schlimmen Umstände ertragen, weil diese Art von Entbehrungen Energie und Kraft sein würde, um mich selbst zu leben. diese Zeit. Und ich stellte fest, dass ich niemals die Person wie er sein würde.

Gnathological instrument

As a matter for regret, a miserable affair happened.
A precious and expensive articulater, Charles E. Stuart designed fully adjustable Gnathologic device in Dental field disappeared in the museum showing case.
I happened to find out it in the storage place in the condition of being lost of  incisal guide pin and separated upper plaster cast.
When I asked where it is to the chief of the stuff, he replied it's somewhere and  he would seek it later, however longer I might wait it all day long, the time to close the place, he prepared to come home, and I said to him, then bring it to me tomorrow.
Probably he reluctantly thought, he served the bent and distorted guide pin with apologizing the fault caused by one of the stuff. But, he never declared who did it by name.
Falling down accident was the reason to hide the articulater!
Layman or laywoman cause such kind of mistake sometimes, because the bows upper and lower are separated in Arcon type articulater, not jointed in the hinge portion.
He made up his mind to cover the punishment by a joint and multiple responsibility , it's nothing but a Japanese way of thinking as if he looks a person with warm and gentle mind.
He keep concealing the evidence forever or until it becomes obvious?
On the other hand, I have different way of regarding that I put and emphasis on the point, the importance is how we can countermeasure the accident, repair it or order a new part to the manufacturer.
Hiding or dressing up as if nothing happened are not the correct and fair way to go. Sorrowfulness in his mind let him do so?
I never scowl or punish on any mistake if it had not been done intentionally.
The importance is the countermeasure immediately after the accident!
We should think over about the problem all together, how to do that, it has nothing to do with the punishment applied on a specific person.
I must teach about that with some gentle distraction, a bit difficult, to a different generation boys and girls.
Remembering my past, my Boss in the institute of the Graduated University punished me utmost if it had not been done by myself but by himself, I endured on the sever circumstance, because this kind of hardships would be some energy and power to live myself at that time. And I determined that I would never be the person like him.

40 years old ENYA 60 X

A radial mount for ENYA 60 X was fabricated with wooden plate to be burdened on a flying motor testing airplane, Sukhoi 31.

Though the radial mount  is set on the bulkhead by way of 4 points rubber insulator, I designed to support with rubber plates in addition for the purpose of avoiding combustion knocking vibration. This kind of mounting method might spoil the true maximum and ultimate performance of the motor, but the effect of prolonging the lives of potentiometers in the servo's construction as well as of all the moving parts in the airplane. 

Rubber insulators for the motor mounting take effect for silent flight, vibration and combustion noise including that is produced by propeller's cavitation in the sky and that is similar with combustion noise. Most of the noisy air plane amplify both noises on main wing and fuselage surfaces, in short, they play a part of noise amplifier in the sky. This is why the method to separate the noise causing origin with airplane body at the point of the first bulkhead by means of setting any insulation materials, rubber.

But, remember here, a slight fluctuation on the motor thrust line affects on the flight, most of the pilot might feel some funny reactions to every direction.

Considering the physical property of the viscoelasticity in rubber material, below JIS #70 coefficient is not  recommended for the purpose here. 

This motor had not been operated as long as 40 years just after once testing operation with Tuned pipe on Curare 60.

As a secret information, the main crank shaft supporting bearing is a very seldom one, the outer lace diameter is 2 mm wider than ordinary #6903, so the engraving on the front case for supporting bearing does not accept #6903 so far as the space here should be fulfilled, a ling spacer must be required if popular one is desired.

This is why ENYA 60 X has not been used as my first line fighter's motor, however deeper I might love the specific character of ENYA 60 X, good performance producing stout construction and Aluminum alloy-Chrome plated cylinder design.

שריר עבודה על VW חיפושית סופר

בעיה קריטית קרה במחשב הראשי שלי הבוקר, איך זה קרה? זה לא מתחיל בכלל, AD-Aware ותוכניות Spybot SD רץ אמש, כי היו הסיבה לתקלה? עכשיו אני יודע כמה אני מסתמך על מערכת אינטר נטו לחיי היומיום שלי. אני לגמרי מחזיק מעמד המצב!
התקנה מחדש של מערכת ההפעלה ב HD החדש פתר את הבעיה הפעם, אשכול התנגשות עשויה להיות הסיבה.

רדיו אתלטי אימון הבוקר נזכרתי על העבודה שריר על שלי VW סופר חיפושית אתמול.
אם לשפוט על פי שיטה ראו דרך על גלגל קדמי חזית במצב ine, ערך רב מדי נצפתה, ההיסטוריה הבלתי נשכחת בעבר נקרא שוב, הרס מוחלט של השיחים התחתונה זרוע התחתונה, הייתי חייב לעבוד שרירים הגדול ביותר!
תגובת ההיגוי מוזר תוך כדי הסתובבות, התנגדות מכנית קלה מאוד רק כאשר היא מפסיקה בלי בלימה המבצע, הרגשה נהיגה לא מוסברת רע, יציב היגוי עמדה מרכזית, כמה אי הנוחות שנצפו.
למעשה, אתמול נאבקתי, למעשה, החלטתי לפרק את בניית הצירים הקדמיים כדי לבדוק את מצבם של שיני הצירים, שברי הגומי בהם.
לא היתה בעיה מוזרה נמצא שם אחרי הכל, אז מה גרם אי התאמה על ערך נגרר, 11 דקות ערך זווית?
כנראה לדמיין אותי כי הלחץ המתמשך מכיוון מסוים עלול לגרום ללחץ אלסטי קבוע של התכווצות חומר גומי בין השיחים, זה סוג של תופעות כמה פעמים קורה.
זכור כי משקל הנהג על המושב לא צריך להישכח בעת מדידה והתאמת על יישור ההגה ואת בניית סרן, שהוצג לעיל, 3 מקרים פולי מלא מים 18L נקבעו במצב.
בכל מקרה, הנוהל של dis- הרכבת ועקב מחדש הרכבה של בניית סרן הרכב גורם לי להרגיש עייף כל כך, זה נגרם על ידי הזדקנות?

Muskelarbeit am VW Super Beetle

Kritisches Problem ist heute Morgen auf meinem Hauptcomputer passiert, wie kommt das? Es startet überhaupt nicht, AD-Aware und Spybot SD-Programme liefen letzte Nacht, das war der Grund für die Fehlfunktion? Jetzt weiß ich, wie sehr ich mich für mein tägliches Leben auf das Inter-Net-System verlassen habe. Ich bin völlig in Aufrechterhaltung!
Die Neuinstallation des Betriebssystems in neuem HD löste das Problem dieses Mal, Cluster-Clash könnte der Grund sein.

Radio Athletic Training heute Morgen erinnerte mich an die Muskelarbeit an meinem VW Super Beetle gestern.
Nach einer durchsichtigen Methode an den Vorderrädern war zu viel Wert zu beobachten, eine unvergessliche Vergangenheit wurde wieder aufgerollt, die komplette Zerstörung der vorderen Unterarm-Gelenkbuchsen, ich war zu einer größten Muskelarbeit verpflichtet!
Seltsame Lenkreaktion beim Wenden, sehr geringer mechanischer Widerstand gerade wenn sie ohne Bremsvorgang stoppt, unerklärliches schlechtes Fahrgefühl, instabile Lenkzentrierung, einige Unannehmlichkeiten wurden beobachtet.
Ich wurde gestern tatsächlich gerungen, ich entschloss mich, die Vorderachsenkonstruktion zu demontieren, um den Zustand der Scharnierbuchsen und den Bruch von Gummi in ihnen zu untersuchen.
Es wurde schließlich kein merkwürdiges Problem herausgefunden, was machte dann eine Diskrepanz beim Tow-In-Wert, 11 Minuten Winkelwert?
Stellen Sie sich wahrscheinlich vor, dass die andauernde Belastung aus einer bestimmten Richtung die dauerhafte elastische Spannung in der Gummimaterialkontraktion in den Büschen verursacht haben könnte, diese Art von Phänomenen passiert manchmal.
Denken Sie daran, dass das Gewicht des Fahrers auf dem Sitz nicht vergessen werden sollte, während Sie die Radausrichtung und Achsenkonstruktion messen und einstellen (siehe oben). 3 mit 18L Wasser gefüllte Polykoffer wurden in Position gebracht.
Wie auch immer, die Prozedur der Demontage und des Wiederzusammenbaus der Achskonstruktion des Fahrzeugs macht mich so müde, dass sie durch Alterung verursacht wird.

Muscle work on VW Super Beetle

Critical problem happened on my main computer this morning, how come? It does not start at all, AD-Aware and Spybot SD programs ran last night, that were the reason for the malfunction? Now I know how much did I rely upon Inter net system for my own daily life. I'm completely in holding up condition!
Re-installing operation system in new HD solved the problem this time, cluster clash might be the reason.

Radio Athletic Training this morning remembered me of the muscle work on my VW Super Beetle yesterday.
Judging from a see-through method on frontal wheels toe-in condition, too much value was observed, unforgettable past history was called up again, complete destruction of front lower arm hinge bushes, I had been obliged a greatest muscle work!
Strange steering reaction while turning, very slight mechanical resistance just when she stops without braking operation, unexplainable bad driving feeling, unstable steering centric position, some inconveniences were observed.
I was wrestled at all as a matter of fact yesterday, I made up my mind to disassemble the front axle construction to inspect the condition of hinge bushes, rubber fracture in them.
No strange problem was found out there after all, then what made discrepancy on tow-in value, 11 minutes angle value?
Probably imagine I that the continues stress from a specific direction might have caused the permanent elastic strain in rubber material contraction in the bushes, that kind of phenomena some times happens.
Remember that the driver's weight on the seat should not be forgotten while measuring and adjusting on wheel alignment and axle construction, shown above, 3 poly cases filled with 18L water were set in position.
Anyway, the procedure of dis-assembling and following re-assembling the vehicle's axle construction makes me feel tired so much, it is caused by aging?
