Rc Depron Boeing 737-500 40mm Edf

I have a passion for Rc airliners, There are not many available build your own kits, mainly only almost ready to fly kits, so ive designed my own Boeing 737-500. It is built from depron, lite ply and balsa. Its been designed for 5 channel radio.

Step 1: The Plans

The first step was to locate some good plans to build from. There was none i only found a 3 view cad drawing on the official website in the airport planning, then i set about creating the cross sections.......

I designed this to be cut out on my cnc router, i have since converted it with added co2 40 watt laser.

Step 2: Cutting and Assemble

Once the parts are cut out, it is a slot together construction, the only templates that are not supplied is the nose and tail sheet pattens, these are easily enough recreated by curving some depron and trimming to fit.

Step 3: Assemble

once the nose is sheeted simply add the nose /cockpit blocks and sand to shape. the same with the tail, the wings are held on with magnets.

Step 4: Assemble the Wing and Edf Housing

the wing simply slots together, a carbon fiber rod 2mm diameter gives the wing strenght, the edfs housing are simply to assemble and sheet.

Step 5: Finishing

the model was designed for retracts for the scale look. you may wish to ditch them for weight saving, I finsihed the model in the british airways theme, totsl weight with 3 cell lipo is 450g.

2 servos in the wings, 1 per elevator and rudder, 1 for steering, retracts not hooked up for maiden flight.

Hey Brett, do you know where the CoG is ?

[marphvienjie.actuatebuilders]

also waiting on the CoG, i have 1300cm wing span

[vikramkannur]

what is the wing span of the model? Will it work out if i print the plans on a A0 sheet? if i add retractable landing gear the weight will increase to around 600-700 g w/o battery. will it fly then? what would be the ideal weight

[marco.wieseckel]

yes it will fly if you buy the right Impellers one impelller generates arround 1,2kg thrust and is availibel on amazon vor 40 Bucks

Hello,
Is looking impressive. I would like to construt it.
What electronics you use? ( Battery, Motors, servos etc?)
If I use 5mm foamboard is ok?
What is the thikness of wooden board's parts?

Thank you!

[marco.wieseckel]

No i think its not but the wooden parts are 3mm thick

Hello from France !
It is possible to have the plan DXF or DWG for my CNC please?

Thank you!

[marphvienjie.actuatebuilders]

What is the center gravity of this? I scale it to 150%. wing span is 1300cm

[rkozak]

Can you provide DWG or DXF files?

[Solarp]

wow this is classy and amazing i will be building this as a winter build this year what is the total wingspan of this model so i can get some scale on the parts ?.....i was thinking of creating a pusher and inserting the motors coming out the back of the nacells...

[Ascovill13]

I am currently building this I am wondering what size retracts I will need? Just need to know the length needed to have clearance from the ground to the engines?

here are some pict of my finished model
also the last pict, is the cg placement the the same as yours?

[jacobc158]

what size edf?

will a 45mm work?

[jacobc158]

this is the easiest and best looking rc boeing 737 i have found:)

[seamster]

Wow, this turned out really impressive!

Got a video of this in flight? That would be so awesome to see :)

[lrlacy]

It's certainly an elegant appearing replica. If it is supposed to actually fly via RC, then what about engines, fuel, associated controls, etc.? Thanks.

[bravoechonovember1]

there are propellers in the jets (4th step 8th picture)

[AMTP1]

Could you possibly do a video or another instructable on the process of taking the plans and developing the cross sections? I have been trying to find something showing how to do this. Great job!

[d3ath101]

Flight vid would be awesome.
