Hallo,

In this document you can find the instruction to assembly the flying wing published on Thingiverse by me. The model flew very well so you can print and fun in very short time. The design was optimized to have less part as possible (just 9 parts to printer) and to be ready to fly in few minutes. This instruction is related to version 05 that is considered stable and working properly. Future versions must be considered just improvement and this instruction could be taking as reference as well. The RC model works very well and is one of the first pure flying wing RC printed present today on the web (summer 2016). In the Thingiverse page you can find the video that show some phases of the fly

Please reproduce and fly, and at the end let me know your comments and suggestions. Will be very appreciated “remix” (with modification and changes) and “make” on Thingiverse page with pictures with your models. Enjoy the fly Carletto73

Ciao,

In questo documento sono riportare le istruzioni per l’assemblaggio del tuttala pubblicato da me su Thingiverse. Il modello vola molto bene quindi lo potete stampare e fare volare in poco tempo. Il progetto è stato ottimizzato per avere meno pezzi possibile (sono 9 pezzi da stampare) e per essere pronti a volare in soli pochi minuti. Le istruzioni si riferiscono alla revisione 5 che al momento è stabile e funzionante. Future eventuali versioni dovranno essere considerate solo dei miglioramenti ma questa istruzioni rimarranno valide. L’aeromodello funziona molto bene ed è uno dei primi modelli tuttala stampati alla 3D oggi presenti sul web (estate 2016). Su Thingiverse potrete vedere alcuni video che mostrano alcune fasi di volo. Vi invito a stamparlo ed a volarci e aspetto i vostri commenti e suggerimenti. Saranno molto apprezzati “remix” (con modifiche) e “make” sulla pagina di Thingiverse con le foto dei vostri modelli. Buon volo

Printing of the parts

To maintain a low weight and allow to print with a common 3D home printer (like Prusa) are needed few tricks. Dimension of the parts

The flying wing was designed to fit into a standard 3D home printer with working area of 200x200x200mm. Due some safety margin that sometime took the slicer, could be that the cube area dedicated to a part is bigger than the real needed. In this case, when you load a STL file into your slicer, you can have a warning massage that advise you that the part is over the limit of your printer, and ask you if you want continue. If happen you can check that, instead, the real part is into the limit than you can answer YES. My printer is a standard Prusa I3 homemade ad I warranty that all parts are printable by every printer with a working area of 200x200x200. Positioning of the part in the bed of the printer

The height of every part is less of 200mm instead the horizontal dimensions could be bigger than 200mm, for this reason you have to place the piece into the bed with 45% angulation. Other, the slicer put the infill grid in a fixed point of the bed not depending by the design of the part to printer. When you slice a part, before print, you have to check where the infill grid is located into per part and adjust the part position into the bed of the printer in order to have the most efficient positioning of the infill. Below you can check where I suggest to put the infill in every part. Shell/perimeter

The parts have to be less weight as possible. For this reason, many parts are made with only one perimeter of 0,32mm thickness. My printer has a nozzle of 0,35mm diameter. It is important that the parts are built with only one perimeter. I saw that the slicer is able to build perimeter more or less bigger than the nozzle diameter. Left/right part

In order to have a symmetrical assembly the STL available are only for left wing. To print the right parts, you have to use the mirror function in your slicer

Assembly

In my case, sometime there are some error during the printing (just 4 or 5 holes). Seams that sometime the printer is not able to keep the thickness of the shell 0,32mm. I don’t know what depend, maybe my slicer is very old. If you know please let me know. This kind of error don’t is a road block, sometime is only a aesthetical issue, anyway is better to fix it. I correct this hole with CA glue and tape (normal for office). For this activity I prefer the cyanoacrylate fluid. Below you can find what I use and a sample of fix

Aileron fixing

The ailerons are fixed with steel rods and are blocked in between the two part of every semi-wing. Before to glue the two pieces of wing, and fix in the meantime the aileron put the steel rod and check the aileron movement.

Glue

The best results I’ve achieved using cyanoacrylate medium. Maybe the best cold the episodic bycomponent but, for my experience I noted that in case of very strong crash the parts soldered with cyanoacrylate was dismount and, directly in the field is possible to fix again the parts with new CA glue.

Motor fixing

Use the dedicated holes to pass the motor wiring into the canopy. If you use the connector of 2mm diameter you can install also before because the hole is able to accept. Fix the motor with only two screws. The pass of the screws is 16mm, according with BE1816 motor.

Use a 5030 propeller. With 3S battery an BE18062300kv, the consumption is below 7A. Carletto73

Servo/aileron connection The servos are integrated into the wings. For this is needed a 3,7g servo. A 9g mm doesn’t fit into the dedicated space. I buy this kind of servo on Aliexpress.

Positioner the servo in the central of the run and fix the arm. The cables go directly to the vane into the wing. Before fix the servo pass the cable. Use bi-adhesive tape to fix the servo to the wing. Be sure that the cable arrive to the receiver. In the filed I’ve put also a tape over the servo to fix better it.

Use a steel rod bar to connect the ailerons to servos.

Wiring ESC

Fix the ESC with bi-adhesive tape. On the field for two times my ESC, was go in failure on fly, due the high temperature rich. My ESC was 12A but the motor consumption was only less then 7. To me this is because my ESC is born for drone and the mosfets are not equipped by a heat sink because the air of the propeller go directly to the ESC. Instead in the flying wing is closed in a vane. For this reason, I will change the Esc with a model equipped by heatsink

RX module

Also the RX module must be fixed with biadhesive tape

Battery

Use Velcro to fix the battery. Be sure that is possible move upward or downward the battery to have the CG in the right person (indicated by two semiball under the wings)

Weight

Be sure to use very light components. In my sample the total weight in fly is 358g (12,63 oz). I noted that motor is able to take off very well, in my mind it is possible to manage model with more heavy. I’ve also check without motor and the model seam equilibrated. The weight of only plastic part is 256g

Center of gravity

Under the wings there is highlighted the correct position of the CG
