Test flight

Pressurized OS 25 LA motor on TETRA Rookie 10 was fairly adjusted, YS Regulator and main needle on the carburetor for 25 FSR has been well balanced, though the fuel inlet nipple direction is not favorable, too tight between the crank case, grinding a bit adjustment could accept the eccentric modification. This is an indispensable ceremony for ordinary motor to invite YS fuel pressurizing System, the narrowing closing fuel flow construction is the key to establishing the system. Because the fuel regulator cannot control the flowing at the most closed phase, slow speed fuel must be controlled mechanically.
Rookie 25 with pressurized OS 32 F motor flew well today showing some potential to draw all of F3A P-17 maneuver pattern, of course combustion condition changing or motor stop did not happen.
"Hornet" with YS 45 FR also flew well, as a new attempt, precise adjustment of the Tuned Pipe setting length was performed, because the pipe-in point has not been apparent, rough setting had been done several times. Today, I could recognize the pipe-in point clearly, so set it up at that point, probably, plus minus 1,3 mm from this point would be the adequate setting position.
Over 6 m/sec front against window made the landing sequence a bit difficult, just a tip of 12-6 wooden prop kissed the ground.
