SuPLAer Cub v6

Here’s my first attempt at modeling a 3d printable plane. 
Because I'm pretty new to 3d modeling, I hope I can get some feedback on this free model! 

Specs:

wingspan 980mm 

weight without electronics: estimated one flying spool - currently printing will update as I go

Description: 

My Father has always dreamt of owning a float plane so I figured I would give it my best shot in fusion at making one for his birthday and double down for the contest and hopefully with a little help from the community we can make this model fly! 

The hope is for it to be 99% 3D Printed, with the addition of a few carbon/wood dowels if needed (again have no experience making planes before), and ofc the motors/fc/servos…. 

Parts are all Exported from Fusion as STL's ready for your favorite slicing program. I have yet to print, but have PLA light weight filament, and PETG for anything contacting the water…

Again I am brand new to the RC hobby, and have only a couple months of messing around with Fusion

As always, 

Have a great day!  

BUILD, ELECTRONICS, ETC INFO:

V2 additions :

• re-worked nose cone
• re-worked floats (now have internal support & hopefully they can take a beating now)
• re-worked prop size & angle
• added windows
• added wing supports (hopefully if the wing hits the water this will help)                            

v3. added

• rudders to floats
• rudder control
• Added pins/mount plates for float supports  (the idea is everything accept the servo can be printed) 
• re-worked all supports to floats insuring more aerodynamic
• re-worked float supported (added pegs for ease of installation) 
• exported individual STL's (incase single parts break or fail during print)

V4: 

Updated Wing STL (now print left and right wing individually) 
- makes spacing between flap and fuselage the same

Updated Fuselage_2_

• Now "v3" in model folder
• Strengthened for printing, ( my first print failed due to not having enough material around the windshield) 
• Added new windshield & side prints. (can cut out the fuselage print and glue these in place after if you want translucent windows)

V5: 

• added wheels
• added “float support” & “wheel support” ( print whichever landing gear you plan on using) 
• re-working plane to have no floats and just wheels
• used proof of concept: https://www.thingiverse.com/thing:135209 for the shocks! please support him! 

V6: 

• added print files for floats and other files. 
• re-exported missing STL files. Sorry everyone! 

HAPPY PRINTING! 

PRINT INFO 
BE CAREFUL THESE ARE SET UP FOR 20+HR prints. 

-have AT LEAST the required filament on your spool, filament break detector installed, and keep those fingers crossed you don’t have a power outage. 

• working on wiring diagram (BIG thanks to the Beginner FPV drone community on fb) should include everything needed from the batteries to the servo weight types. along with FC compatibility and BETAflight basic flash/install guide

CAREFUL PRINTING:

part : fuselage_2_v2 - I am working on strengthening after adding windows & removing material for print model it doesn't print as strong anymore. 

WIRING DIAGRAM:

• Lol please help

ELECTRONICS NECESSARY: 

again this is my first build so go easy on me… 

you will need the following: 

• 6x Servos 
• 1x Brushless motor
• 1x Propellor
• 1x Servo wire splitter
  • 1-3x Batteries (2-3s)                                                                                                                  I am thinking to upgrade to 4s so I can use my current FPV drone batteries (again new to plane builds not sure how much power will be required to fly with floats) 
• 1x ESC - Flight controller (basically up to 7" prop drone fc) 
• Lead ballast ( for weighting the plane to not fly all over the place) 
• 1x hinge sheet - https://www.amazon.com/
• 18 AWG wire for ESC to Motor
• Wing tube: approx 1m needed (8.5mm holes for wing (order 8mm and use glue)  needed… https://windcatcherrc.com/product/carbon-fiber-tube-6mm-x-4mm-x-1000mm/ (Actual link to buy tube)
• Super Glue (gel recommended) 
• Plastic Model Cement (stuff works great) 

I plan on ordering the following, please let me know if I should change anything… 
 

Flight controller: 

FRSKY F4 FLIGHT CONTROLLER WITH BUILT IN XSR RECEIVER (I fly with ELRS normally but this FRsky receiver is cheap and compatible with my radio) 

but could be swapped with a similar setup. (please refer to youtube or ChatGPT for advice) its been helpful for me. 
 
 

If you've read this far, please rate the model! 

Check out these links as i found them helpful in designing the plane:

I've definitely spent a couple days working on this project, if you print it, or it helps you out at all on your own 3d printed plane journey please hit the LIKE button!

Those Prusa Points are always awesome, but sipping on coffee while re-modeling in Fusion makes my day ;)
