Built, but waiting for ARL license before I can fly FPV in Japan. Everything went together well enough. The frame is solid and looks really nice. Top mounting the batteries and as someone pointed out the battery will sit right at the prop line.

I wanted something sturdy with all the cool new features, so went with upgraded hardware, Armattan 1407s, TBS SmartAudio and Runcam split. Split PCB is right against the top plate, so no fear of the SDcard gate opening. Also, only three screws to remove the top plate and I have access to SDcard.

Using titanium 6mm screws and a whip antenna the dry weight is 199 gram. This is with Runcam split, a 30.5 x 30.5 flight controller and TBS SmartAudio VTX. Not the lightest for a 3 inch quad, but the feature trade-off makes it worth it.

build notes:

  • Armattan uses M3x8mm bolts to lock their propeller down. I swapped them out with titanium ones to save about 1 gram of weight.
  • To get the TBS VTX to lay flat and not have the wires exposed to any props, I had to raise the FC 10mm and use a shorter middle stack mount for the Split PCB.
  • Littlebee 20A - Spring ESC were flashed as A_H_20 and needed to be updated to A_H_25 to work. With the older software the motors would lose sync and all esc would reset trying to spin up. Increasing the deadtime to 25 seems to resolve this issue. Found this info in a forum post.

Did you ever get issues with your escs and the flight controller?

The only issue were the esc needed to be updated to a different version of blheli. Not a newer version, but a actual different version of the software.

Did you power the tbs from batt directly or from fc pads?

From the FC, It's unclear with this board, but sometimes the FC cam pad has a line filter for noise

Really, really beautiful.

Sweet build! Have you checked to see if the props are in view when the split is recording in HD?

Finally got to checking, the props can be seen in the recording, but just barely.

Haven't tried flying yet, so not sure how props at speed would show up.

You got me thinking, and maybe swapping from 2.5mm to a 2.8mm lens should be enough to remove the props.

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..
