YS regulator & Pegasus

Rookie 20 flight yesterday gave me much information about the introduction of YS fuel pressure injection system to OS 32FS motor, as a matter of fact, original 3H carburetor was replaced into 4H that has some different fuel narrow down control spray nozzle, not needle but a triangular slit. Of course, the original angular shape was modified to adopt with higher fuel pressure condition with YS system. Comparing with the narrower slit in YS45FR motor, the shape was re-modified and this experimental trial was to the point, not hesitation, no tendency of coughing was observed while the test flight instead smooth transition from slow to middle and to hi was obtained. Rookie 20 trainer shoulder wing plane would have finished as a motor test bench as actual flight use and the motor would be replaced into regular one 25FSR on the other hand, 32 motor would be burdened on TETRA Spitfire Mk5B 50 4cycle scale plane as a stable and good conditioned power plant, because I have a intention to take part in 4C Scale model competition in future.
I found out the cause of right side twisting bad habit of YOSHIOKA Pegasus 40 while looping, the parallelism between the main wing and stabilizer is not established, both of the main wing are set with some slight right side inclination! This discrepancy would be corrected by grinding the holes on the fuselage for connecting center aluminum alloy pipe. The holes would be reformed by self curing resin material. As this plane was given to me for free of charge including servos, a FM receiver and OS 40LA motor, I have no way to complaint on this discrepancy, the critical one, twisted right main wing had been corrected before. Probably, the effort to have given program mixing condition yesterday would be in vain by the correction of main wing setting condition onto the fuselage.
