Replacement of the lubricant from ordinary Silicone grease into Carbon Graphite in the gimbals stick construction required several change of settings, gimbals tension spring strength, D/R ratio and the value of Exponential for all the 3 channels, aileron, elevator and rudder.
All the moving wings were controlled too much under the former settings, also the neutral return spring ratios were weakened.
It proved that the slipping resistor between the lever and the pins affects all the setting condition in the gimbals stick movement.
Automatically, it does on the actual flight itself.
It might be regarded as a trifle matter at all, but piled trifles is not always trifle but is important and produces differences.

PILOT Junior is now construction preparing for the next Golden Age & Old Time meeting in next Autumn.
The power source is L.M. Cox Medallion 15 with modified front carburetor holder for ENYA 15 throttle valve. The part was made by the Lost wax casting method DIY.
As I prefer some stable operation from lo to hi rotation, I chose Medallion rather than more hi power Tee Dee 15 that has hi compression head and double Schnerle scavenging ports.

Running away phenomena of my ATX Tower PC obliged me to maintain today.
Long thrown away machine caused Thermal Runaway after a few hours use.
The servicing method was thought to be some easy task at the beginning, but actually not, because the piled dust was combined by mold growing deep inside of the cooling fins.
Both CPU and video card were cleaned by disassembling including power supply.
At least once a year of periodical maintenance should not be ignored.
All the machinery are invaded by the invisible flying mold and Mycelium, they are one of the food chain undoubtedly. Also they can be an allergen of the heavy allergic symptoms.
Bacteria, mold and virus are sometimes inconvenient for human being, but they have the reason to exist on Earth.

Film coating with Oracover on "Elica" has been completed relatively smoother than usual. Simple 2 colored with Cub yellow and Purple clear to obtain the confirmation of flying attitude. Recognition for the direction of the fuselage and the main wing inclination is the first purpose while she is in the sky.
Larger main wing area might be suitable for 60 Schnurle motor, but I have chosen OS 55 AX motor with normal muffler following the regulation by Cassiopeia 70 class competition.
Nobody participating in the meeting would not bring any High wing model for F3A meneuver competition, but I do that. Mixing function would cover bad habit enough to keep straight flight while Knife Edge phase including aileron differential function establishing rolling axis. Improved controlling stick smoother function in Futaba 10J entry Tx model would be helpful.
Fully DIY designing and costructing High wing model might be outstanding among China made ARF pure stunt airplanes.
Controlling servos would be Futaba Digital 4.8V S9255 for Helicopter Rudder use.
Let's see what will happen in the competition scenery.

We had some aftershock around 5 o'clock this morning, metal storm doors were trembling. Though I was afraid of more shock like yesterday after that, no more shock was observed. Thanks to the desperate effort by the engineers and the retention measures, Hankyu Rail Road are now in normal operative condition for all the lines. I would like to take Kobe line and Kyoto one this morning for the purpose of checking my working place hoping nothing inconvenient happened by the Earthquake shock.
Radio news told some miserable report that an elementary school girl was killed by a heavy block fence, sandwiched unluckily. Many flowers and bouquet were there praying for the souls. Hanshin Awaji Big Earthquake occurred tens years ago was remembered in my mind, praying never to come back again such a miserable destruction.
Dangerous constructions and buildings are not recognized until some resultant collapse and destruction might happen. More checking and correction by the Administration should be performed before the disastrous affair.
Repeated Natural disaster shows that our sophisticated Scientific technology cannot control natural phenomena enough to avoid any accidents.
A happy day today will not always come tomorrow.

Recent Gas Supply meter has safety auto cut off mechanism and it was activated by the shake caused by the Earthquake this morning.
Automatically hot water supply stopped in my house, in addition bathing room has also problem, no hot water.
Thanks to the description in Osaka Gas HP, I could recover it's original function safe.
The fact that the telephone line connected with the dealer is so crowded, not a few people must be in trouble of no Gas supply.
Anyway, the natural disaster like this morning influences to many directions.
Workers and students must have some tremendous inconveniences because of stopped traffic.
My friend told me that the bridge on Yodo River is so crowed with the pedestrians unusually, and even now Hankyu Kyoto line is not activated.
Some system must had been destroyed on the rail way, I hope it would be recovered next morning with my best thanks for the desperate effort by the workers in the maintenance area.
