Talking Designing a 3D printed RC plane

Hey everyone! I'm a senior aviation engineering student working on his bachelor's thesis and I've decided to build a 3D printed RC plane. Initially I've based my work on a similar paper I've written for a 3D printed plane project, however, as I've started laying out my hardware and designing the shell I've realized that my COM was WAY off and I also no longer have the wing span restriction I've had in the previous paper so I can probably optimize the design better. I will probably have more questions later, but currently I'm looking for general advice on best ways to deal with a relatively heavy airframe, since that's the main disadvantage of 3D printed planes. Currently I have all the hardware I need prepared around a 400W brushless motor. The main requirements of the design are low takeoff and stall speed, ease of control and durability. High top speed is not important and neither is battery economy. Additional carrying capacity for equipment is a big bonus, but not a necessity. Other than that, it can be high wing or low wing, biplane or whatever. I'm not quite new to RC but I haven't built a plane since I was 13 so I'm rediscovering a lot of things somewhat lol.

Thanks for any help!

EDIT: Thinking about programming the plane to use flaparons as well. Anything important I should know in regards of that?

Thingiverse.com. Some interesting ideas, some way out ideas, some useful ideas.

3D printed planes are inferior to the traditional methods in every possible way- weight, durability, appearance, time, strength/stiffness, and so on. The only plus is that they are only marginally harder to build than a foamy. Anyone who knows basic structural engineering can explain why.

So is the project requirement that you use 3D printing to make something? Or are you just looking to use a cool new tech to do the project?

As for flapperons, to be honest, you should have textbooks that can explain that with much greater detail than we can provide here.

Yeah, 3D printed construction is a requirement

Have you thought about buying a profile foamie or plans for a larger profile plane and printing the parts? This is the direction I would go.

There are some 3D printed planes out there. I've heard they are pretty rickety, but if you examine them you can at least see something that sort of works.

As for your design goals, a high aspect ratio wing and lots of power is going to be the ticket.You might be able to make an undercambered airfoil work, but understand that the stall characteristics will be more temperamental.
