3D model description

Simple all-in-one print quad frame for light and small quads.

Fully parametric so you can customize for your own board and motors.

It is designed for those tiny motors that can be used without a "foot" aka they just have a bearing tube out back. This tube can be pressed into the holders saving weight.

Make sure to add enough offset to your motors so you can fit large enough props. The offset is distance from center of board so make sure you take half the prop diameter and add half board width. Then add some clearance margin for the material in controller frame.

I plan on adding extra trays you can fit on top for RX and such as well as a battery-caddy with landing-legs for fitting on bottom.

Finally there may be a canopy that attaches to the top as well.

Edit: Added v1.1 with trays

You can extend the supports/spacers on the trays by setting a parameter ofcource. Use the trays upside down for alternative spacing. They can even be used as battery trays and mounted on underside.

Edit 2: Added 1.2 with propguards

The guards are designed to slip onto each motormount. As such you need to pull the motor out and fit the guard first to use em. It's a compromise of simplicity and printability. Each guard is seperate to allow easy reuse.

Edit 3: Added 1.3 with clip-on propguards, canopy and teardrop type arms as options.

Clipping on guards can now be done any time, no need to remove motor. Simple canopy is done too, to make it look a bit more wierd. Looks best when not using any stacks on top. A tray below is fine though. Teardrop arms are more aerodynamic and scale better for larger quads. They can be printed with very low or no infill for light structure.

Speed controller:



If you use a i86 board from HK know that they have serious issues with high frequency vibration. Any such build should not use a tight frame for holding the board, but instead use a foam tape or other padding to dampen the board-frame coupling. This is especially true for small motors in tiny quads.

i86L / Eagle N6 V2 is a better choice as it uses a much better gyro.
