BanRC2 User Guide
Hi,
Thank you for your interest and welcome at BANRC 3D print gliders. BanRC2 it’s a very
dynamic 2 meters two parts wing glider, easy to print and assemble. This user guide will help
you on how to print and get your glider on sky.
Please do not share the STL files you bought. I trust your best and kindness on this matter.

Overview:
I started aero modalism on 2013 and 3D print on 2016. It takes me two years on design, print,
test & fly the 1st model. Sep 2017 first glider BanRC1 has born, 8 month later this BanRC2
glider was on sky.
The challenge was being to find the proper ratio between the rigidity and weight, easy design
to print and design can be printed with the most printers available in market.
Printer I’m using is Anet A8, with PLA filament 1.75mm, slicer Cura. Glass on bed with 3DLAC.

STL files:
Files are designed for an easy use with printers available in market and all type of slicers.
Important is to use the same setting shown in slicer tables.
You can print the STL files individually or in groups, individually is recommended.
G.Code files:
You can download them on your SD card for directly use them on your printer. Using these
files are on your own risk of your printer safety. OR you can generate your own G.Codes files
using the STL files for being sure that they will be applicable for your printer.
Option 1:
Download the G.Codes on SD card, insert the SD card in your printer. Heat end set to 200°C -
210°C and bed temperature set to 60°C. You can change the speed and temperature on printer
screen. Enjoy the printing.
Option 2:
Slice the STL file, save the G.Code on SD card, insert the SD card in printer. Enjoy the printing.

CG:Glider should be in fly condition.
Do not glue the boom with fuselage till you check the balance of the model according to
weight “gm” of electronics you will use.
Steps:
1- Glue the Rudder Elevator with Boom.
2- Start with boom 700mm.
3- Insert the boom in fuselage.
4- Put the gilder on CG balance tool, if tail heavy, then shorten the boom by 100 “mm”
and check again, if tail still heavy, shorten boom by 50mm and check again. The
boom should be not less than 500mm

Printer:
All printers which have a basic printing dimensions of 200mmx200mmx180mm with heat bed
& Nozzle 0.4mm can print this Glider.
Tip: Before you buy the design, you can test your printer, download the Test STL Files. The
biggest and highest part Wing Part1 if your printer can print this part then it can print all the
parts of this model.
Printing:
Please keep these figures in mind:
-Print the parts individually, not in groups.
-Use raft for easy clean after print. All parts are flat, no need to apply support.
- In slicer be sure “Slicing Tolerance” is activated “Exclusive”. So, the printer can print the ribs.
- To avoid ribs appears on skin, in slicer be sure of “Outer Walls before inner walls” is activated.
-Cooling fan is OFF. For sure the fan for nozzle heat end its always ON.
- Glass on bed. 3DLAC spray for bed adhesive. OR as your own convenient material.
- 0.4mm nozzle head, Parts are designed on 0.4mm wall thickness.
- PLA filament.
- Follow slicer setting values to get the same weight “gm” shown in paragraph “Parts weight”

14
Parts in Slicer will appear as a solid part in “sold view” but using “layer view” will show the
inside details of the part which what the printer will print.

Parts Lay on bed:
Important to lay the parts on bed as shown in photos to guaranty the printing quality. The
most important is to be sure that the part is lay FLAT on bed. STL files saved to lay the parts
flat on bed when they opened.
Part is not correctly Lay Flat on bed. Part is correctly Lay Flat on bed.

16
Tail tips should be at same distance “A” of wing tips
Check geometry, the vertical virtual line “B” connect V tail tips should be parallel to the
wing, adjust by turning the boom.
Wish you a nice adventure on printing, assembling and FLY
