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.

I redesign my old plans on this GA8 Airvan RC plane model. This new version has better performance on flight, more lift, more stable and easier to control. I made the airfoil thicker than the first version. This model is made out of 5 mm polyfoam or depron foam sheet. I choose FlyStark livery because I think that's the coolest Airvan color scheme on the net. This livery decal also shared along with the plans. If you enjoy my Cessna 172 model you will enjoy more, building and flying this model and it's easier to build and fly. It only needs 4 servos, there's no steering on the front landing gear, you can't turn on taxi but the rudder is enough to steer the plane when it's running for take off. The wing and wing struts are detachable for easier transport. I also include 2D pics for 2 pilots and 4 passengers to add realness of the model.

In this episode we'll making wing mounting, tail section and stabilizers. The tail section and stabilizers construction are pretty straight forward and all made out of foam sheet, no need for hard spars. Only the vertical stabilizer that needs a small plywood part. The plane so far is very light weight, just like I expected. The one that I have not expected is that, I thought the tail will be tilted downward because of its weight, but it isn't, so that's a good thing.
