This is a sub 250g (124g w/o battery) analog freestyle prototype drone. It's equipped with a split cam (runcam hybrid or split) and a TBS crossfire receiver. The hybird allows 4k recordings, without the extra weight of an action cam.

The used AIO ist quite powerful, actually overpowered for this setup. But I have it a try, and got dissapointed. It only has two UARTS. As it seems to be built for the Air Unit, one would assume it's perfect for the digital brother of this build. But I decided otherweise for the lack of the 3rd UART.

With only two UARTS the GPS cannot be connected as UART1 is used for cam control and UART2 is used for the TBS crossfire nano. I was unsucessful remapping S5 and LED Strip for soft serial.
resource SERIAL_TX 11 A15 #was LED Strip
resource SERIAL_RX 11 B04 #was Motor 5

The AIO is flipped, so the motors have to be remapped
resource MOTOR 1 A10
resource MOTOR 2 B00
resource MOTOR 3 A08
resource MOTOR 4 A09

If you want to use bidirectional dshot for the RPM filters the ESC has to be flashed (to 16.9).

Check out the digital version for additional hints.

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..
