Looks like a nice frame. I wonder how it compares to the Lumenier QAV250. BTW, sorry the part labeling is a little wonky right now. If you edit your build and tag your parts they'll save properly.

I have not yet had a chance to do a hands on comparison to the QAV250 frame. However, one reason I chose this frame over it was I wanted arms that were separate from the frame. As this is my first quad racer I expected to break the arms a few times. Thus replacing a couple of sheered screws seemed a better idea than replacing a full frame. As a side note this frame is derived from an untested prototypes frame. You can see the original here:

Was thinking maybe a few additional parts sections could be: OSD, Antenna, and maybe LC Filter? Although LC Filter may be best as a misc part, because they are often included in PDB and OSD.

Some good suggestions. I'll see about getting those added.

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
