This is awesome and the first time I've seen anything like it! Is it fun to cruise around with it some at "low speeds" of like 100mph? You

Billster   10 days ago 

Thanks! Yes, it wasn't setup for cruising and it has a symmetrical airfoil, but it still makes a significant amount of lift at 100MPH. It starts to become noticeable at around 75.

Why you not use f80 motors?

Billster   13 days ago 

My thoughts were the extra power would not overcome the extra drag from the larger diameter. Only way to really find out is to just build both and see. The other reason is the record holder is using cobra 2207.

I've thought about this quite a bit - it's worth it to get the f80s with a slightly larger lipo. I don't think the 234mph run by quadmovr had this level of aerodynamics - you'll easily be able to get the world record with that setup. Maybe slightly more pitchy propellors? How many amps did you pull on the run?

Yes you are absolutley right about the lipo, the main reason I chose this one was because of it's small size. I knew the 1300 would be a better choice but it just had to be quite a bit larger to make it better in the looks department. I sort of just hoped the battery would live up to the claimed burst c-rating but I knew it probably wouldn't. Another issue is the long power wires this configuration has, further reducing the voltage. The max amps it did was 145a total, only for around half a second. I'm really happy with the speed considering how it's pretty sapped for power, but obviously was hoping the battery would be a little closer to the 190c burst rating. The props still have more speed left in them, the current record holder is using the same.

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..

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..
