Rookie 10

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 manouevres. 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.
