AOS UL7 DJI 03 with Crossfire Nano Pro. The frame is only about 175grams. Installation is abit tricky. Since the arms are snap-on to both the bottom and top plates when it sandwich together, it tends fall out while I was working on building the guts. I use zipties to hold the arms down temporarily. It has plenty of space to work on. the head the middle and the back bays.... they can all holds fc stacks or air units. And you can mount 20x20,25x25 or 30x30 Stacks. The front mount is compatible with DJI original camera or DJI 03 camera.
I'm using BrotherHobby 2806.5 1700kv, ideally you want 1300 or 1500 for more effeciency. However, I've already own these motors so I just put them to good use.
I've flown with Zeee 6s 5200mah 100c lipo(730ish grams) and got about 15-20mins just crusing. The CNHL G+ 6S 2200 mah up 70c (395grams) will gives about 10-11mins cruising, not bad for a small lipo on a 7' quad.
Originally I had the dual antennas on the side but it annoying when straping the lipos on there, it gets in the way, so I moved the antenna to the back and runs 2 150mm u.fl to RP-SMA cable to the back for the TrueRC Matchstick antennas. Also I used Fettec Spike Absorber with a Panasonic 35A 1000uf capacitor.
So far it's performs well. I put an 85% throttle limit to make it more tame. The 1700kv motors are too snappy for my tastes especially on a 7" quad. I love the frame, its my first 7' build. I'm happy with it.

i have the o3 airunit an the same stack as you. how do i connect the o3 to the fc. the cable doesnt fit that dji provided. sorry if its a dumb question im brand new to the fpv world

no not dumb at all. its dumb that Tmotor decided to use a totally different connector and not put any addition soldering pads on the FC so you can solder directly. I had to use one of these connector... the end I'm holding goes to FC and the ither connect to 03.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. 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..
