The distorted elevators on both side of Kyosho Sonic Acro 1600 were also corrected the fundamental construction, by cutting them in two pieces horizontally like fish cooking and glued together in pressurized jig condition. All the distortions were corrected fairly after this procedure. The upper part of the fuselage was separated to open the service hole for the convenience of Li-Po battery replacement. Some reinforcement on the fuselage is required if the hole is formed on the important part to form solid strength of the fuselage construction.

The stabilizer position of Goldwing MXS-R 30 cc has moved to posteriorly and the elevator servos on R/L both side Futaba BLS 173 SVi were set on the position promptly. The modifying method to adopt onto F3A model by extending it's tail moment would be successful, so I hope. But nobody uses 30 cc gas model in F3A field, there must be another reason? Anyway, I proceed the way to be believed by myself. Big change is nothing but that of the power source, from gas motor into electric BLS motor. Because, not so much linkage movements are not required in F3A field, horn extension adaptors are not used and the round original horns were used to put ball joint parts directly, especially, 2-6-3 radial ball bearings were set on the rudder servo horn to be connected with wire linkage directly. Setting bearings here, slipping resistance would be eliminated utmost and be prevented the occurrence of backlash.

The main wing construction accuracy was checked in Kyosho Sonic-Acro, and the unignorable torsional strain, twist, bend and distortion were found out in the ailerons on both sides, in stead, no unacceptable discrepancy was observed in the main wing construction, it's the most unlikely in Chinese factory fabrication, the main wing accuracy would be established when connected at the center.
Cold off season interval is an indispensable period for the preparation of new fabrications of new models, gradually, the competition machinery for myself are increased in number.
