Happy flying all!

(note that the camera, FC, receiver and antenna in the parts list are items I nearly immediately swapped out and prefer! )

can you land without prop damage? i feel like this adds very little benefits...

Great job! Did you notice some differences and advantages from normal motors placement?

To be totally honest - I think you'd have a hard time telling the difference unless yuo'd been fling for a LONG time and were very used to a particular style of build. Betaflight accounts for most differences very well in 3.5. I have noticed perhaps a smidge better battery life, though I also find that my props are more prone to damage.

have you tried having the back ones on top and the front ones at the bottom of the main plate?

Not yet, To be completely honest I've found the change to be mostly aesthetic so I would expect any orientation of motors on the latest BetaFlight releases would feel pretty much the same :)

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..
