Assenbly Report

YAK-55's motor mount is very different from Hyperion SU-31 "10e". SU-31's mount is too much weak ! Actually, SU-31's mount was broken twice. However I can say that YAK-55's motor mount is stronger than SU-31's mount.
Canopy magnet latch is very good. Battery setup is easily and doesn't need long time.
Tail gear is fixed. Original design is set to rudder, I set to fuselage.
Start with model balanced at CG point furthest forward, 60mm (2.4inch) from wing leading edge, measured against the fuselage.  Set Dual-Rate switches at 65% for Aileron and Elevator for first flight.

Flight report

Take off, it's easy, because this model has big power. But It is not easy to fly 3D & torque roll with the rudder.  Wing loading is not so light and my skill is very good ??
