a simple frame body for a small quadrotor, designed around ~1/2" square towel bar and the KK flight control board.

You should be able to print and fly in the same day!


the towel bar I used is about 16mm wide - I included the OpenSCAD source so you can tweak it to your needs.

Hardware is #6-32 nuts and flathead bolts for arms/frame and #4-40 for the control board. Use velcro straps in the slots to secure the battery.

Hi, Nice work :) Can u also share the other thing files like the motor holder, Craft landing gear. Regards..

Hi, i am interested of creating this but first i have to know how much cm^3 the whole parts are. Is there any way you can calculate this value? :) Thank you.

Some slicing software will calculate this for you. The amount of plastic used really depends on your slicing settings (infill density, number of permieters, etc etc)

Thank you for replying. Do you know any software that can do that job for me? Um, also i cannot understand a core part of this idea. How are you able to communicate with arduino? Do you need to buy a wireless card/grs card for arduino? Its hard for me to understand the communication part of it. Thanks for your time my friend :)

What sized motors is this for, and what is the final weight?

I had some 1500rpm/V motors, so that's what I used on this build. Probably too fast for a quad though. 18A ESC's and a 7.4v 1250mah battery - and it weighs in at 645g.
