Polyester Glass Fiber

Thanks to the application of Polyester Glass Fiber processing on the stabilizer for YOSHIOKA Sunday Alpha 50, my initial purposes to reinforce and to keep flatness were established, though some weight increase might happened, torsional deflection strength has been increased enough to endure the forces while drawing maneuvers. Bad memory of vulnerable Flying-Tail construction leading to complete destruction in YOSHIOKA Pegasus Acro might obliged me to do that.
Anyway, PGF reinforcement in balsa wood construction is very effective to model airplane in necessary portions such as engine mounting construction and wing connecting surfaces.
Lighter weight and enough strength are the conflicting issues at all even in the actual airplanes, recent accidents happened on me forced to chose the latter item, as a matter of fact.
Following the saying by Mr. Yojiro Akiba, not a single anxiety in F3A model airplane should not be existed.
I just remembered the 3 bad items.
1. Unreliable Radio
2. Bad habit airplane
3. Motor that has stopping tendency
