My first 4-inch, first LR, first dead-cat frame.
I took the smallest M10 GPS and still couldn't fit it well. No idea how to fit the antenna - TBS Unify took all the space leaving almost nothing to fit the mmcx plug-in. It was designed for a 4S battery but tried it with 3S in my room and it was a very stable hover.
Requires GPS test and antenna replacement.

Upd: ordered TRUERC CORE 5.8 (RHCP MMCX90 125MM). GPS is working but heavily suppressed by VTX.

146 grams.
7mins on 3S 450mAh
17mins on 4s 1050mAh (with XT60-XT30 adaptor)

Hi, may I know how you do the wiring for the vtx? the 7-36v go soldered to 5V or Bat? got the same aio and vtx as this build. thank you.

hi, use the bat pad; it's the only sufficient power source for VTX.

It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

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..
