there is a lot of weight to be saved replacing the mmcx vtx/mmcx to sma adapter/longrange antenna with a lighter 800mw vtx + ufl antenna. sub 300g would be possible.

I kind of want to build a even lighter one
there is still a lot of potential. go for a light 14x14 cam, like the nano racer ~4g, instead of a ~8g micro eagle/ratel. my vtx (9g)/antenna(11g)/mmcx-sma adapter(3,5g) are pretty heavy. a simple 5g 800mw vtx and a 2-3g ufl antenna would reduce weight by ~20g. also the new upcoming runcam split 3 nano will be a few grams lighter than the turtel v2. and maybe it has a good enough fpv picture to get rid of the second cam alltogether.
Great Job! I'm currently working on a similar project and hoping to have it finished by the end of the week! I'm using a little beefier motors though - Hyphylite 2408.5 1622kv for 7" on 6S. Also using a WhitenoiseFPV Synergy F4 with Crossfire Nano and a TBS Unify. I don't think with those porky motors I'll be able to get it under 300g (40g per motor)... I'm looking forward to seeing photos with the canopy.

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..
