Description

----------------------------

NOTE:

This is my first design of a 3D printed RC plane using LW-PLA in vase mode. The model is quite complex and does not include features to make assembly easier, which can be tedious.

I was hesitant to release this model because it's not fully developed yet. But, since many people have requested it, I've decided to release it anyway.

However, please note that there will be no assembly guide provided with this model.

However, you may interest in the newly design SUB250 flying wings – Breeze Model X.

A much more user-oriented design.

----------------------------------------------

Printed with Bambu PLA-AERO, see it flying in the official ad video in the product page: https://store.bambulab.com/products/pla-aero

Wingspan: 1M

Wing load: 15-18g/dm^2

Flight Weight: ~220g [with 1106 4300kv motor and 7.4V 500mah battery]

Rudder and Elevator are pull-string-springs controlled.

The ailerons are very thin and are printed as part of the wing. You'll need to separate them by cutting along the designated lines with a knife. There are slots on both sides where you can insert a piece of TPU or PETG that is 0.8mm thick. These pieces should be secured with CA glue for the linkage

For the body and wings, just glue them together one by one using CA glue. There's no need to align any hinges.

Please see photos for CG and more assembly references. Also, remember to use Bambu Studio's assembly view to find the correct locations for the parts.

Print both profiles.

Despite its design challenges, the plane flies very well. Its light wing load allows it to fly slowly. With the wing foil used in DLG (Discus Launch Gliders), it can also fly fast. When it catches a thermal, it floats like a bird.

------------------------------

I understand that the current design isn't perfect, but I've learned a lot from it and they are improving my future designs.

More models are on the way in the coming weeks.

Please follow me, and I'll keep you updated when they're released.

great

@flyinANT

Thanks for the sharing, it's a beautiful plane. I tried to print with PLA Basic, but this is not feasible, the strength is too low to assemble, wing part is OK, but body part is fragile, can't take it from plate without breaking it. I will try to print it with better material.

I would love to see your second attempt at 3D printed glider!

@majianjia

Thanks! Glider is pushing too much to the limit of 3d printing. I am currently designing a normal fix wing. May try another glider in the future.

Love your work, definitely looking forward for both of the models!

Bambu should have credited you on their product page. It took a while to find. This is very similar to a glider I had as a child, that could be powered. It was fine as a glider but didn't fly well when powered. Very cool you moved on to a flying wing.

@majianjia

Thanks, glider and flying wing are my most liked, too. Bambu do credit me and I licensed them to use the model.

would you be intrigued in revisiting this design?

The designer has replied

@majianjia

Thanks, sorry but not for this particular one. Because this glider was my first attempt and didn't planed well enough. The cad design was full of defects that i couldn't change them easily. However, i just posted my second design, based on what i learn when i built this glider, which is a small flying-wing. If you haven't checked, i would recommend you do, called Breeze Model X, it ia much easier to print and assembly. i won't design a glider soon but i am already working on a new plane.
