Balance is the key!
I designed that frame with two objectives in mind:

  • As much power as possible while still under 250g
  • Get the CoG right in the propline

To get a motor with maximum thrust I contacted T-Motor (who had an already pretty good motor in ther lineup) and convinced them that a little more kV, some small changes on the stator and a nice paint-job on the bells would provide the perfect package for this whole category (250g 3.5")
To get the biggest mass (battery) centered in the prop-line I reduced the stack-mounting options to 25.5mm or 20mm AIOs (8mm high + 2mm for stack-nuts) and designed the arms around those.

If you build it with an analog VTX there might be budget for a naked gopro :-)

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.
