This is a bit of a Frankenstein re-make of another frame (http://www.thingiverse.com/thing:1691618) to accept the Beecore F3 board. The Beecore FC made it so I can't use the space under the FC for the battery. I made a battery holder to mount 400mAh cells. I used this camera mount with roll bar: http://www.thingiverse.com/thing:1815820

Honestly, I'm thinking this thing can easily run 800-1000mah 1S cells for maximum fun. Weight minus battery is 45g, 39g minus prop guards. the 8.5mm motors are 5g each so they are waaaay heavier than the 6mm motor builds. The speed is actually pretty fast outdoors but flies nicely indoors if you keep it on Horizon/Self-level mode. Let me know how you like it!!
