Description

1/29/2017:  Added a new v1.3 Lower component (arms) after 9 months of flight testing.  The v1.3 is just a little heavier than previous versions, but is much stiffer and  impact resistant, particularly in the motor mount region.  Note:  this new revision is being released in metric.  All previous revisions were in inches.

*********************************

4/29/2017:  Added a new v1.2 Lower component (arms) after good success in flight testing.  The v1.2 overall thickness is reduced, with more material added to the regions surrounding the motor mounts.  Overall weight is about the same as v1.1, but with a reduced risk of cracking near the motors.

*********************************

2/25/17:  Added a new v1.1 Lower component (arms) after some great flight test results.  The v1.1 lower is lighter and stiffer than the v1.0 lower.  The arms are tapered for greater structural efficiency.  Standoff interfaces adjacent to the motor mounts are eliminated to save weight.  Both models will remain available as build options.

Birdbone Helium is an ultra compact 210mm FPV racing/freestyle quadcopter frame designed to compete with carbon frames.  Frame weights less than 100g total (Lower + Upper) are feasible with good stiffness and durability. 

The builder must choose the lower printed frame wall thickness, infill density, and infill shape necessary to achieve their design goals (based on material choice, etc).  See below for some example settings.

For the Lower component, use lots of brim and your best 1st layer adhesion game to prevent warping of the arms.  Techniques vary by material.

An optional motor guard stiffener is included to protect the motors, and offer additional frame reinforcement if needed.

The upper component accommodates a typical HS11XX flight camera and most action cameras using a velcro battery strap.  The flight camera angle can vary between 15 and 60 degrees.

The builder is encouraged to create new components to further customize his/her build.

My current setup is as follows:

PRINTED PARTS:

IMPORTANT:  This is a large part, so warping can be a problem with materials like ABS, polycarbonate, etc.  Use lots of brim, 200% first layer extrusion width, and your best bed adhesion strategies to prevent warpage.

See pictures for suggested model print orientation.

ELECTRONICS (will vary depending on build):

RMRC Dodo r3b FC, Matek Powerhub PDB, Littlebee 30A BLHeli_S ESC's, EMAX 2600KV "Red-Bottoms", TS5823 VTx, Lemon RX DSMX satellite Rx, Foxeer Arrow HS1190 flight camera.  Batteries:  5S Tattu 1300mAh 75C.  Props:  RaceKraft RK5051 (balanced) and DAL "Indestructable" 5045 Tri-Blade v2 (balanced).
