Flying-Tail in Pegasus Acro

Yoshioka Pegasus Acro invites Flying-Tail design as it does, the supporting construction is very important, durability, accuracy and 3 dimensional backlashes.
Original designing is 8 mm dia. inner & outer sleeves Aluminum construction, it won't last 100 flight under 45 class grow motor vibration however some grease lubrication might be done well there, destructing energy caused by combustion phenomena should not be made little of even model small motor.
Because of the upper reason, I made up my mind to apply miniature ball bearing on the necessary portions.
Though I tried to follow the original design following instruction manual, only this complicated part was modified as my own. Weight increasing by the changing is very slight not to affect the original performance.
Stabilizers would be completed soon and a residual work is main wing construction, paying the best concentration not to distort at any rate.
