Wooden Radial Mount

A few number of wooden radial motor mount have fabricated for YOSHIOKA Sunday Alpha 50 in order to make use of this new one as the actual flying motor test bench for my several piled stock. Situated the fuel tank just under the CG point as it is, the volume was increased for the sake of 60 motors. Expanded wing span to 1600 mm and 40 dcm2 area accept some 60 class motors with adequate power support.
The shoulder style designing and larger displacement produces the degree of freedom to adjust the CG point, moving the battery point, anteroposteriorly. 350 to 450 gram difference is available.
As a forcast after several motors trial, YS 45 FR, YS 45 FS, YS 60 FR and YS 60 FS would be remained, because the YS Regulator System is the only one that I had been getting accustomed as long as 10 years intending contest application.
