Flying test bench "Pegasus"

YOSHIOKA Pegasus 40 plays a part of good motor test bench of 40 class motors, because it is relatively easy to construct the motor mounting construction.
So, did I make several wooden beam mounts for various 40 class motors, such as ENYA SS35TV, 35-4C, OS 40&46 LA, 46AX, YS 45FS & 53-4C including OS FS60 & FS61.
Remember the principle that in case of motor replacements, precise adjustment CG is required by moving battery weight backward and forward.
Comparing the weight OS 46LA and ENYA 40 TV, 100gr difference exists. Light weight 46LA has no crank shaft ball bearings but plane metal supporting construction, difference is brought by that of supporting construction including case material physical property.
As my opinion, no crank shaft supporting ball bearings are not always necessary if it is operated below 13,000 rpm. Suppose that this tiny 46 motor has the capability to fly huge Ed Kazmirski's "Taurus", probably the performance would exceeds Veco 45 motor equipped in it. I'm completely satisfied with the performance of OS 46LA motor.
Though the manufacturer had stopped this production few years ago, slim, tight, light and powerful motor like this is nothing but to be continued it's production.
