I have looked at this build several times, and had lots of thoughts about it. I have to ask, what is it like flying a 4" querd, on 6" motors? Is it fair to call it a 6" motor, when it has a 4" prop on it? I think about weight, and it's placement, and how those concerns become more important as your aircraft gets smaller, and I i'm all salty for no reason, like it has something to do with my life. Then I think about the idea of putting the biggest motor you can in your vehicle, and then someone comes along and goes: "No, bigger" and your all "It won't fit" and they're all "lol, bigger tho, real talk", and then you see 27,000hp jet drag cars... AAAAAAND i'm back onboard.
I don't know how to feel here.
So tell me: what is it like? Will you make a video where you fly your 5" then fly this immediatly after, then fly a lil guy after that. Talk me through it. I really want to know.

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..
