Studied much yesterday

Rookie 20 flight adjusting trials for as long as 6 hours yesterday from early in the morning taught me much about the principle of basic flight characteristics.
Too much application of motor drive axis to the right direction causes an unexpected shift of the direction especially in the phase of the followings of a rising up rolling maneuver like the secondary acting 45 degree rise up on cornet with half role. Deeper consideration led me to the conclusion that the thrust axis of the motor has caused the result, also the fact was proved while Knife Edge flight setting. Left side KE is easy and floats enough even with small original rudder area pulling up to the sky direction by the motor thrust, on the other hand, right side one could float and was difficult to keep the horizontal flight pulling down force of right side motor thrust, the result was supposed to be mainly caused by the inequality of the motor thrust.

The method of setting two elevator servos are worth introducing because of the reason not only for elevator looping action but also for propeller slipstream, the effect is not always influenced only on vertical stabilizer but on horizontal stabilizer. So, the Programmable capability with 6 ways equipped in FUTABA 10J 2,4 GHz transmitter is utilized for the purpose promptly, remembering that the 2 of 6 are already occupied by the Knife Edge flight setting, rudder to aileron and rudder to elevator. With all the programs, Knife Edge straight flight is possible with all the primitive trainer model Rookie 20 for beginners and layman. Depending on the establishment of critical program adjustment, F3A P15 maneuver is possible?

The capability to see, to watch, to gaze at it and to recognize is necessary to correct and to adjust the bad habits of the flight. To recognize means there exists the way to do that. "The flight is everything in F3A Competition", so said by the former World Champ, Mr. Y. Akiba. I didn't know the true meaning 30 years ago when I was in a precious circumstance to fly F3A model together with him at the same flying place. But, now I can remember his saying and follow it, though it was 30 years ago, the principles of Science is the same.

The needle valve one notch is very sensitive under the condition of YS fuel pressure system, and this dull shaped(original for natural aspiration) tip of the needle valve makes it difficult to establish some fixed and stable condition of fuel supply on OS 32 F motor, lowest rotation and closed throttle valve condition and also middle speed transition to hi rotation, the balancing of diaphragm pressure regulator adjustment is very difficult, I dare do it until the success to be satisfied performance of throttle works, a half a year has passed insisting on this system? One by one, my understandings on YS regulator system proceeds, too long period of time of lowest rotation operation causes motor stop, because of the reduction of pressure in the fuel tank, but this phenomena has nothing to do with the actual maneuver flight.

Utilizing the established YS manufactured motor and establish it's condition is relatively easy for me, of course I know that the technology had been done by the special engineer, Mr. Kondou with his desperate efforts of development and research factory in Nagoya who is famous for his highest capability as a YS Doctor, but with another company's motors with YS system are difficult, this is why no F3A flyer does not invite OS 160 FX motor, 2 cycle and simplest construction with enough power for F3A maneuver competition. But, I dare do that depending on my selfish feelings on YS pressure regulator system for as long as a half a century.
Anyway, keeping some machinery and doing the best condition is difficult and time consuming work in my life, on the other hand, just feel and express in some way without any actual action, like poet might be a easiest lives?
