Radio equipment obtained by bidding in YaHoo Auction at 2,300 yen had some problem, the main potentiometers keeping the controlling pulse were moved according to the former owner, so disassembling of the transmitter was obliged regardless of my favor. Connecting factory adjusted standard servos, I did setting the terminal positions of the main potentiometers one by one with some keen concentrations. Checking semiconductors inside on the cards, no defects especially on capacitors were found and the main functions to control an airplane were kept well in spite of the ancient production date of 1985. Remember, circuitry formed by semiconductors lasts unlimitedly if there occurs no short nor disconnection, problem is electrolytic capacitors arranged. Also, lubrication of moving and slipping parts in the mechanical closed Gimbal construction was performed for smooth stick movements.

Rookie 10 trainer plane is now undergoing for replacing motors from Fuji15 into OS 25LA, resulting lack of ground height on the nose gear was compensated by rewinding coil portion with one turn prolonging about 20mm longer, so, the threatening of propeller tip touching with the ground surface in landing situation has eliminated. By reducing the number of turns in this way, the spring constant of the nose gear would be increased as a matter of fact.
The wing area of Rookie 10 has 20dm square, this plane would fly like a pylon racer if some 25 motor might be embedded, in the most of flight scenery, middle motor speed is used, of course fuel and air mixture ratio is also important, so the carburetor of 25 FSR which has middle speed mixture control system was connected and the full speed is used only when rise up phase in case of F3A pattern competition manuevres. Most of the flyer has 2m wing span big plane in F3A field, but I dare fly in the condition of a smallest plane.
The smaller the plane is, the more difficult to control in P15 pattern drawing.
It is worth flying well with a baby plane with the condition of difficulties, controlling trainer plane with wider dihedral and antisymmetric airfoil.

It looks so trifle to play with model airplane like a kid, but, also is worthy for geriatric like myself to cultivate a dynamic vision in the sky talking with wind and air that is invisible but has enough curiosity to communicate with the physical property of "Air".
Now, I'm preparing for flying "Currare" designed by Hanno Prettner & Hanna Prettner, the father of Hanno P., in Austria who were famous World Champion Ship winner for a long period of time. Remembering the past, I shook hand with them and had a better times surrounding dinner table, faces of good old friends both Japanese and those from foreign countries come to my mind.

I visited an Italian restaurant "Sakuragumi" situated in Ako cape that is the most Western side of Hyogo Pref. yesterday. As a matter of regret, the Spaghetti served at that time spoiled our table, because the lack of boiling period of time resulted in a unpleasant table. The reason for apology by the staff was too poor to satisfy our complaint, in Italy the same, hard and sticky to the tooth? Anyway, that was not an indispensable place to visit with much expenses and I determined that never come there again. In addition, we did not recommend any love and passion on the dishes those are most important to be expressed. Any business should be done from the bottom of heart.

I have been skipping blog these days, devoting myself to an old hobby is one of a reason. Model airplane by Radio-Control is my best fun, because I can communicate with the presence of air. I have been concentrating on my cars, especially on the wheel alignment and axle constructive geometry these ten years, cars go on the ground so to speak 2 dimensionally, but now transfer I to 3 dimensional trial.
First of all did I correct the discrepancies on the main wing, twisted and distorted constructions were the task to be done utilizing a special jig. Obtaining the main wing without twisting is the indispensable requirement to enjoy comfortable flight avoiding any unexpected reaction, so to speak bad habit. 3 evils for model airplane flight are unreliable Radio, motor with stopping habit and a aircraft with bad habit.

Habitual idleness prevented me from writing a everyday blog these days, on lust Sunday I enjoyed old hobby, flying a mode airplane radio-control, at the country side place. I found out some change in my mental state, all the stress was removed in my back, it was an unexpected phenomena, so I made up my mind to revive my old hobby. As a first step, I subscribed to the negligible liability damage insurance for safety of all.
As the plane had been left untouched as long as 30 years, the main bearing set at crank shaft supporting portion was rust resulting poor motor performance. Replacing frontal and rear bearings recovered the original performance. In order to regain a sense of model airplane flight requires several trials. I was a candidate to take part in the group member of the flying club there.
