A replacement arm for the dji Firewheel quadcopter.

The photo shows the version before the published one that doesn't have a hole for the motor wires.

I struggled to get the screw holes in exactly the right place, but I think they are ok now. If not, let me know. It's about a four and a half hour print on my Replicator so I haven't bothered to re-check, but I'm sure I'll be printing another soon, given my piloting skills!


This needs to be a solid as you want to make it and printed with support. I printed it at 50% fill, with two shells and it doesn't flex. It also weighs less that the original arm.

However, in crashes it does break easier than the original ones, but if you don't crash, that's not a problem.

The motor mount holes should be drilled out to 3.5mm and just replace the centre plate screws with some self tapping ones to get a good grip on the plastic.

Cool arm, but I noticed that its not quite symmetrical, seems to have about a 1.5 degree cant to it to the right if looking at it from the top with motor mount at top. I noticed because the holes don't line up I have the hobbyking version anyway so I was trying to modify the hole placement and kept noticing the arm mounting at a strange angle. I have tried to fix it but dont know how.

Yeah, I see what you mean. The holes seem to line up reasonably well with the motor mounts on my Flamewheel and the slight skew shouldn't affect the handling (the autopilot will compensate, if it needs to).

The things was just knocked together in Sketchup when I broke the proper arm and wanted a quick and dirty fix while a new one arrived. What can I say/ It worked for me, so I shared it. Can't you open the Sketchup file, fill the holes that are off and sink new ones or are you not a Sketchup user? If you're not, give it a try. It's free and dead easy to pick up.

Yea, I use sketchup but i"m pretty new! to that and 3d printing. its been a good learning experience. and yea I dropped it on the kitchen floor and broke the stock arm lol. I did get the holes in the right place now, and I tried to fix the Skew but made a mess. Oh well. Thanks!

Is this 450 size, or 550?

Hello, did you design this in OpenSCAD? if so would be great to see the source.

No, did it in Sketchup.

Would you consider sharing the sketchup file?

No problem - done.
