Update 2:
-Added a new Swept Wing with a larger AR and span. With this wing is also a new wing mount for the wing.
-Added a new wing mount for foam core wings, wing mount clamps around the foam wing to hold it in place.
-Added a TailInterface top and bottom plates that allows swapping of the tail surfaces.
-Added a horizontal stabilizer pivoting gimbal.

No videos for the foam core wing yet (I made the wing too long and ran out of fiberglass, it exploded from flutter)
Update 1:
Added a new set of landing gear (LW), along with a plate for attaching miscellaneous attachments, such as a gopro/crosstour.
A mount for a crosstour (gopro should also work) has been added along with the plate as well.
Another wing mount has also been added with a higher wing incidence that improves flight performance. This new mount is also lighter and was printed with 0.5mm wall thickness and 8% gyroid infill, reducing weight by 48% over the previous mount.
A new video is posted below with the changes, along with new photos added above. I'm working on documentation for the design now, which should make it easier to build/make new parts for the plane.

Greetings, the goal of this project is to have a modular platform that I can use to swap out different designs to test and have easy reproducibility/repair-ability.
Modular parts:
Motor Mount
Wing Mount
Wings
Landing Gear
Planned Modular Parts:
Tail Surfaces
Misc. Attachments
I am working on decreasing the weight of some of the parts, and strengthening other parts.
Currently I print all parts with 0% infill with these exceptions:
Landing gear: 100% Infill
Wing Mount: 10% infill [gyroid]
I have flown the plane twice now, with the first flight being in manual mode, and the second flight in FBWA and ACRO mode. The second flight ended with the motor vibrating the nuts off of the screws holding it to the motor mount, and subsequently ripping the motor mount apart. I have reinforced the motor mount, and hope to never forget to glue the nuts in place again (this is the second time I've forgotten).
