3d-printz Sinbad : Motor and final installation
Now that i have all parts it is time to install the motor and finalize the project. I had one samll motor that could fit into the nose and provide enough thrust for this model from hobbyking https://hobbyking.com/fr_fr/ax-1806n-2100kv-brushless-micro-motor-19g.html . A light weight motor, 19g, for 337g of thrust while the glider is for the moment less than 350g.
With this motor i choose a 10A ESC also from Hobbyking https://hobbyking.com/fr_fr/hobbyking-10a-2-3s-esc-1a-ubec.html
Patrick from 3d-printz helped me for getting the right motor nose design allowing a good fit by keeping a nice profil of the fuselage. After 3 iterations we got the right one :
Finally i was able to install the motor, screwed on the its support printed in LW-ASA, and that i glued on the fuselage. With a 850mA 3S battery and the receiver all fits in.
Latest measurements are the global weight and the CG. CG is exactly at 45 mm from leading edge as recommended in the documentation, i will adjust it during the early flights.
I will update this blog with maiden and first fligts video when local weather will allow me to do it.
3d-printz Sinbad : Final steps
I am glueing all parts of the Mini Sinbad, with cyano only. It is a easy process that needs some attention as the glue cures very quickly. I followed 3d-printz assembly guide and did not found any problem with it.
I painted wingtips, cockpit and canopy, and a filet on the fuselage using same colors as on the Eclipson EGW80. For the servos i reused support available with the Eclipson model, printed in LW-PLA.
I am still missing the motor and nose, waiting for this one to come and be sure it will fit in the small area. Otherwise i will used the pure glider nose version. Current weight without motor and ESC, receiver and battery is 331g.
3d-printz Sinbad : parts weight
As Colorfabb is claiming on his web site LW-PLA and LW-ASA are very light weight material for 3D print and thus allow to build light models.
Parts | Weigh |

WingtipL | 4.3 g |
WingL2 | 17.7 g |
WingL1 | 22.4 g |

The Sinbad will definitively be very light and i weighed each printed part.
Current total weight of all parts is 282 g. I will need to add 2 9g servos, one receiver, motor+esc and the 2S 300mAh lipo battery, and all links and rods with rudder and elevator. Final weight should be around 420/430g.
3d-printz Sinbad : all parts printed
I managed to print all parts of the Sinbad in one and a half week, doing this every evening and 2 week ends. Here is summary in a table of all times required for each print.

Here is a photos gallery of all these elements
The full kit is ready to glue and being equiped with servos and motor.
3d-printz Sinbad glider
I am starting to print the Sinbad glider from 3d-printz.at using mainly Colorfabb LW-PLA. I am sharing this journey through my blog to help you printing this plane if you need advices with this material.
Before this project i already printed a plane with the LW-PLA, the EGW-80 EDF model from Eclipson. Here are some pictures of the finished plane.
EGW 80 finished, total weight without battery is 468g, all LW-PLA and some LW-ASA.
The printing environment is an Ender 3 Pro with the BIGTREETECH® SKR Mini E3 V2 board and TFT35 E3 V3.0 screen. I also installed the BLTouch for a better bed level management. I will share my settings of Cura 4.8 i am using to slice all parts.
Base slicing parameters are the one from Eclipson with just additional changes related to Sinbad recommanded by 3d-printz.
Here are the fisrt 2 parts i printed, the canopy and the cockpit and a first timelapse for the canopy.
