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.
This is my first model that is using EDF or Electric Ducted Fan. I choose the C variant of F-35 aircraft, mainly because it has bigger wing, I wanted to make sure that it will have enough wingloading to fly. In this model I also share with you couple new things beside by using EDF alone. I share how to make a clear canopy and using servo driven retractable landing gear. The landing gear was bought from Banggood for about 10 dollars a long time ago. What I learned by using EDF is, it's pretty expensive if compare with pusher prop and will fly in a shorter time. I only have effectively 2,5 minutes to fly the jet, the rest is prepare for landing. You have to use 4S 2200mah with minimum 60C discharge rate, otherwise you will have a damaged battery after the first flight. Also EDF models need a decent paved and long runway. If you can access one, EDF jet is amazing.
In this episode on How to Make RC Airliner Boeing 737-300 part 2, I'm going to share with you on how to build the wing and install
the retractable landing gear to the wing and how to join the wing. In the beginning I also made a tutorial on how to build the belly
wing fairing on the fuselage. I switch all wheels from original 45mm foam wheel to 70mm rubber wheel, to match the scale size of
the real aircraft wheels. As I mentioned on part 1, I will make this aircraft model as light as possible so I made an unordinary
joining system for the 2 pieces wings. The 2 wings just held together with U shape stainless wires on top of the wing and plastics
and screws on the bottom side. The jointed wing, next on part 3 will be mounted with 4 screws to the fuselage, thus will make the
wing stronger on the joint.
I miss flying FPV but I don't have any plane for that. My last FPV plane, the Sky Arrow 1700 mm is crashed and beyond any repair. So I made this RC plane that I named it "Walet". Walet is an Indonesian name for "Swallow", a small and agile bird. Actually I planned to make the wingspan 1300 mm but I forgot to update the 3D model then it came out with 1400 plans. I think, what the heck, then I continue finishing the plans. Because it was surprisingly big, I released the smaller size plans, which is 1200 mm. My Walet is already equipped with FPV setup now, but still manual, no flight controller and GPS yet. In this episode I share with you only how to build this plane, not the FPV setup. I hope I can cover about it on other episode.
There are many request for me to build an RC airliner. I once build a small Boeing 737-800 in the past, the wingspan only 1400 mm/55 inch with pusher prop. But I haven't made the build video tutorial of it and the plans for you to build. So here it is Boeing 737-300 with 1800mm/71 inch wingspan. I will still use pusher prop, this time I will use twin pusher props. No EDF yet, because I haven't use EDFs before, so I will not make this huge model to learn using it. I will make F-35 after part 2 of this Boeing 737 to learn how to use EDF. If it succeed, I will make other EDF airliner in the future.
