This is the final part of Boeing 737-300 building video series. In this episode I am going to share with you the rest of the build to finish this RC airliner which are, making dummy engines, motor mounting, install electronics like ESC, servo and pushrods, paint and decal and finally its maiden flight. At first the CG is wrong (12 cm) and almost crash, the correct CG is 17 cm from trailling edge. On this build I learned more about CG and the first time using that type of retract landing gear.
