Defeated but I'll survive!


Now I lost a favorite "Hornet", YS 45 FR powered and the setting for F3A maneuver pattern almost has been done for over 11 months, I realize that I've lost some index to go. In order to comfort myself try I remember the procedures I had done on my victim, because the legacy I got on the way of nourishing it remains clearly in my archive, know-hows and datum obtained as a matter of fact. Wondering am I in the piled design papers, I'm choosing next model to be built next.
Deeper consideration led me some conclusion under the condition of an indispensable capability to draw F3A P-19 maneuver patterns, PILOT Fighter N-400 or modified Harold De bolt's All American Senior would be my choice.
However completely I might be defeated by the accident the other day, I would survive again like a Phoenix.

GA & OT meeting over successfully

Thanks to a desperate effort by the Executive officers, KMA Golden Age & Old Timer meeting at Uji Kyoto was over very successfully. We appreciate their contribution to the Special Meeting yesterday,especially do we Mr. Ymamoto who is the representative of Vintage division of KMA.
The applicants there are not always from near prefectures, but from Shimane, Aichi, Chiba and Tokyo.
Our friendly relationship becomes deeper and deeper, all are so kind and friendly as to make friends each other immediately after the first conversations. The time had passed like an arrow from early in the morning till evening.
I could have an opportunity to have a talk with a very famous in our field, Mr. Tetsuji Sato who is an original designer of control line model "Phoenix".
Talking about ENYA 20 TV that is one of my bad mood motor, immediately he pointed out the procedure of head screw tightening torque. Uneven and to much torque invites cylinder distortion leading to some bad operation condition. He put an emphasis on the point that ENYA 20 is very special motor that needs keen precise handling because of thinner and weak cylinder construction. Inviting 15 crank case and modification caused this inconvenient result. So, conventional and ordinary concept and principle should be forgotten when reconstruct this motor.
In addition, about an inconvenience on 60X Al-Chro motor that the stuck phenomenon between a piston top with inner edge of exhaust port and Schnuerle ports. He said that it is impossible to cause such a problem because the cylinder inner surface is finished after a relatively thick Chrome plating procedure, so no idea. Imaginable reason, someone in the process in dealing might do some thing wrong, fiddling.
As for my opinion on the problem, too much grinding might be done in lapping procedure causing narrower piston skirt portion forming and it invited slanting diagonally?
Any way, an experienced senior engineer such as Mr. Sato is indispensable person in our field.

I must declare very sad news, "Hornet" was lost and missing in a deep bush this morning just because of my trifle mistake.
I should have waited more 5 minutes before taking off till dens fog disappeared thoroughly,
It faded out into the dens fog immediately after P turn following to taking off.
It's a matter for regret to have made haste to take off early in the morning in the dens foggy circumstantial condition.
God gave me a warning against my Arrogant!

Making haste


Finding out several pieces of strawberries this morning, I felt so happy and some anxiety to be stolen very soon by a wild bird. But it must live to have some food in the urban circumstance, I would forgive them if the affair happens.

The limitation to participate in the meeting, KMA Old Timer & Golden Age at Uji Kyoto is now threatening, 24 th September is the D-Day.
MK Star 15 is ready for that at 98 %, but Star 06 is not yet, make haste as quick as possible, I feel it like a horse race just before the goal.
Once decided, must I do that for myself, to myself and by myself.

Rained cats & dogs

I was drenched to the skin this morning while driving my Caldina, because the driving seat had sponged water!
Carefully checking revealed that the origin of the water was coming from the sun roof, my car parked outside last night and had we relatively heavy rain fall while sleeping. Remembering the past, the first generation SUBARU Legacy LSi (US made and left side steering) had the same problem.
Because of secular change of the rubber sealing material, the space formed between the sun roof glass edge and the roof hole of the body becomes wider gradually to let the rain water comes inside. Of course some drain pipe is designed most of the case, it's hole sometimes crags thoroughly with dust forming, then the disaster like this morning happens.
What I must do is perforating and making reform pass through way for the rain  piling water, and remake the thickness of the shrunk rubber sealing material applying a sticky Polyethylene self fusion tape inside.
Now I have solved the mystery, the stain traces on the inner lining at A pillar portion.
I'll do that troublesome work after drying.

YS system

The main reason to introduce YS fuel pressurized and regulatory system is the stable operation while the maneuver pattern and the unchanging fuel mixture especially on a late acting. Pressurized fuel supply consistent fuel mixture even when the plain rising up or coming down. So, a fine tuning on the main needle valve relying on a intuition is not required if the best setting at the taking off moment is established. From the beginning to the end of the patterns, stable, monotonous operating condition is proved, whatever quicker pattern might be drawn in the sky by the pilot.
In spite of these truth and fact, it's very seldom to come across with YS motors including 2 cycle ones recently, less more, I've never seen the independent YS system invited on the another motors except YS manufacturing.
Contrarily am I fond of this, setting that on OS 25 LA and OS 32 F have I some good operating conditions for both of them, remember here, the carburetor of 25 LA is exchanged with 25 FSR's one because of fuel squeezing mechanism.
YS regulator does not have enough capability to control the fuel amount at the lowest speed, so the only that position it is controlled by the squeezing mechanism. The key to establish the regulator operation is to adjust the angular position it to make the transition from the lowest to middle rotation with smoothness.
Once these adjustment is well done, the good operation described above would be proved so far as any dust like fiber should not be come into the fuel line.
Remember here, any 2 cycle motors would do, because the primary crank case pressure is the same, the amount of combustion displacement has nothing to do with the system. Even 180 motor or 049 would do.
The system mentioned above resembles with the relation between Bf 109 and Spitfire while the WW2, the former had the fuel injection system and the latter did ordinary natural aspirator carburetor, no argument is necessary to talk about the superiority between them.

Comfortable Super Beetle

Thanks to the desperate effort on the thrust angle adjustment, my Super Beetle goes straight without being influenced by any external disturbance such as road surface inclination.
Main factor to establish this ideal condition depends on the procedure to replace front lower arm hinge bushes those were destroyed completely.
The concept to adjust the trust angle was changed from just establishing the Zero Angle to additional precise meeting with front wheels vector direction.
The direction of Vector Directions, F/R should meet with precisely, should be parallel each other while straight running.
The idea this time is Bingo!
Remembering the past for over ten years, it took me long time to come to this simple conclusion, but much indispensable Know-Hows and technologies were obtained on the way.
The fact that I come to the conclusion, Goal is not so important for me, but the experiences on the way is worthy for me and the effort to be exerted there is my indispensable Legacy.

New constructions

Construction of two MK Stars is gradually proceeding and final settings take time unexpectedly.
Moving their main wings forward processes are done to meet with correct Center of Gravity position antroposteriorly, this problems are brought by wearing heavy mufflers and larger displacement motors, OS 11 CZ for Star 06 and OS 25 FP for Star 15 promptly.
Long lasting habitual character of myself to avoid and to postpone any troublesome works must be obliged to do at any rate with setting some limitations.
24th, September is the D-day this time, Golden Age & Old Timer Meeting at Uji Kyoto held by KMA. I make it a rule to participate in it with new constructions.
Because have I many planning to be desired for long time of period and much
materials for the works in my working room, the rate of my processing speed depends on only my own will, intention and motivation. Need I some external factor and power to do that. Consequently, the meeting would be a good and worthy opportunity to be given some pleasant stimulation.
