Well! I had a dream.. And an old 7" build, with an XL7 frame. I have a lot of problem with the stability, and found the FR7 open source project. https://www.airbladeuav.com/products/fr7-7-inch-long-range-frame-kit

USA is too far away for me. So I downloaded the project files from thingiverse, and sent to a local carbon sheet machining: C.Carbon.

This design have a lot of space inside, so I tired how it is looks like with 5mm smaller standoffs. And here is it, my FR7 lowrider! :)
Redesigned a lots of 3d parts from thingivers for the 20mm standoff, and for BN-220 GPS.

If you have any question ask it!

Are you running on 6s or 4s. I have a similar build but my motors are the racer star tmotor 2514 1480kv and on 6s I'm getting fly offs and smoking hot motors it got so hot one time the wire desoldered from the esc. luckily I had the tmotor f55 and that thing is a beast so I at least didn't burn my esc out. Idk it's just my first 7 inch and I'm struggling got get it going yours seems pretty awesome was wondering if you had any tips

I used it with 3S-2200mAh batteries, and for first runs it will be run with it also. My motors are 1850KV and works well with the 3S batteries for 6-8minutes. you can check it here:

If all will be fine with 3S batteries, I'll change for 6S.

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..
