Printed in taulman alloy 910, aside from the flight controller mount and spacers which use ABS.

There's four different top plates:
-1102: fits 1102/dp03
-1102AIO: enlarged camera and vtx mount for AIO fpv systems like the VA1100/Quanum/etc
-1105: fits 1104/1105 and stiffer guards for heavier AUW
-1105AIO: enlarged camera and vtx mount for AIO fpv systems like the VA1100/Quanum/etc

Three different lower plate thicknesses let you tune stiffness independent of weight.

Not sure if it's because I'm using Cura 15.04.6, but I'm having problems printing the flight controller mount. In the layer view or when printed, the spacers are not one piece but instead 6 segments as the thinnest walls are skipped. The racetrack opening for the 4 pin micro JST also has gaps around most of it, the mounting points and bottom grill seems to be formed fine. Nozzle size is 0.4mm on the printer and for the slicer settings.

same issue with simplify3d - strange...

RS90 Scad file cannot be rendered?

Hi there - will this take any 1104 size motor?

The "Print Settings" section says 10% infill, is it a really low value, if printed in nylon does it affect durability at all?

That's for the top plate, where infill only applies to the camera platform, parts of the central body, and the tail. Most of it consists of thin walls that are printed solid.

If I understand it correctly, is that most of the top plate is solid, the infill doesn't matter (it only matters to camera platform, central body and the tail), is that correct?

How about the bottom plate, is it also mostly solid?

Yup. The bottom plate is only solid in the body, camera platform, and bracing going along the pitch axis.

Stupid question: what is "propadapter.stl" for?

Not at all, looks like I accidentally named the prop cutter "prop driller" so I can see how that'd be confusing. It's basically the rotary part of the prop cutter that the prop screws in to.

I see, that make sense. Thanks for the great work and sharing the design!

Which material would be best? PLU, ABS, Nylon?

Did you mean PLA? If so nylon would be the way to go. Taulman alloy 910 to be specific, although I've seen some new materials come out lately that look promising too.

have you got it flying?
Give a picture pls? :)

Ton of pictures over at the RCG thread, just updated the desc with the link

What size spacers are you using?

Which motor do you recommend? DYS BE1104 1104 Brushless Motor 5400KV 6500KV 7000KV

Depends on how you typically fly, but I prefer higher kV and normally use 6500kV.

Good desing men ¡¡

Could you share with me the CAD files?

It's for made another version

Thanks a lot ¡

Thanks Brian! Great Job!

Thanks a lot for sharing this really cool design. Could you please provide some generic tips to get the best prints with Alloy 910 for these parts? I know that it would depend on the specific printer a lot, but still. Support types, perimeters, extrusion width, layer height, infill, speed, adhesive, temperature?
