This is the final episode of Douglas DC-3 or C-47 RC plane build. It's primary using 3mm and 5mm depron or polyfoam or XPS foam. This last video is covering about making the wing, wing fairing, install landing lights, and other accessories like detail of the engine cowl and battery hatch door. The CG of this model is 12 cm from the leading edge, by using 2X 3S Lipo battery it will ballanced perfectly. You can have 8 minutes of flight time using 2 lipo batteries. This plane is a good flyer, short take off, scale speed, and easy to control using combination of aileron and rudder. The landing is also smooth and slow, no flap needed. Unfortunately the retract landing gear was the only downside, one of the servo is failed.

Piper Seneca was once on my wishlist, finally I can get my hand on this type of aircraft. At first I already planned to make Piper Seminole but I thought its T-tail will bring a hard time to build. So to make simple but scale model I choose Seneca II and the end result is surprisingly easy to build. The wing is very similar than the Cherokee that I already built and flown. The performance also very similar to the Cherokee, but with more powerful thrust with twin motors. In this project also the first time I ever use motor for quad/ drone race.

In this episode once again I try new technique, which is applying paint on the inside side of the laminating film. It turned out very good, the film can be use as usual, by heating it with covering iron to activate the glue. Thank you Aero Ergo for the tips. Also in this episode I announce new feature from Youtube which is a membership. It's just a way for you to support me so I can make more model with EDF (which is expensive). A member can download additional decal files. Beside that, in this episode I show you how to mount the wing to fuselage, make the engine cowls, cover the plane and applying decal.

I redesign this RC foam board P-51D Mustang from the original plans that I made for papermodel. I simplify the design for easier building. The main material is still 5mm depron or polyfoam foam board. In this project it's the first time I use 4 of these new techniques. They are DIY spinner, new clear canopy molding, laminating film for covering and DIY retractable landing gear. I'm quite satisfied with all the result, except the landing gear still needs more improvement but, it has lots of potential. Although it worked but still, I will improve it in future projects. This Mustang is fast, even with just 50% throttle, I was trying hard to not hit a tree when flying it. I should add flaps for slower landing, but the time for this project is limited so I'll leave it to you to improvise with this plans, good luck and have a good building time.
