This is an Acrobrat Duo frame with a Lumenier FC/ESC/VTX stack and a RunCam Hybrid 4K FPV+DVR.
The quad weighs about 209g (without a battery), and I've been flying with a 850mAh (106g) 4S RDQ battery.
After building it, I see that it's eerily similar to this FPVCrate build, and that's probably because I got inspiration from several other builds on RotorBuilds that used similar parts. It all goes together great on the Acrobrat Duo frame!
This is the first 3" frame I've built, and I'm really enjoying its nimbleness. It will last for 5-6 minutes on the 850mAh battery and takes great 4K(30) or 2.7K(60) footage.

why the vtx antenna in this place?
Based on where the VTX and Crossfire antenna are, this seemed like the easiest place.
Haven't run it farther away than a soccer field so far, and signal was always clear.
Do you think it should be sent out the back in a higher location?
hi,my question is only about the vtx antenna.
usually a top place for the vtx antenna is much better....near the carbon arm should be a problem sometimes.
anyway nice build....I love acrobrat style.
Thanks! I may try to get an extension cable and route it up.
The issue isn't that it needs to be on top. If anything, BOTTOM is better, since MOST of the time the quad is above you. The issue is attenuation to the frame. If it's not distorting, or causing interference in your video, I say leave it. It may be a little VOULNERABLE run across the bottom like that, for landings. On that note: your front and rear motor wires are in preeeeeety sketchy proximity to your rear props.
Honestly the vtx antenna thing was my first question too, but if the signal is clear, there's no need to change it.
Ah, makes sense! Yeah I'm a little worried about it getting scuffed up on landings. I've added some additional landing pads around it.
The motor wires are about 0.75" away from the props and don't move, I'm not to worried about them getting chopped.
