Finally got to where I want with a toothpick! It's (mostly) a BetaFPV x-knight 3" with a HIFION RC (?) F7 25A AIO board. This board is fantastic since all the important connections are edge-mounted, so soldering to it is a breeze and keeping wires neat and out of the way is a lot easier than regular pads. 25A is likely overkill but maybe later I can convert it to a 4 or 5" with even bigger motors :)

The BefaFPV x-knight frame is super heavy (4mm thick carbon arms!) but also really durable and supports 12mm motor mounts. It's quite a bit more solid than the FPVCycle TP3 frame I've been using with a similar AIO board. I can twist the TP3 arms and feel them torque. I find the heavier frame gives the quad more authority and feels less flighty in tight turns, with a tradeoff of lower battery life.

BefaFPV canopy is slightly modified with a SMA stubby antenna and a pigtail (probably not an ideal mounting location, but I think it looks cool). SMA is just 1/4" so drilling a hole was really straightforward to mount the antenna. I've had issues in the past using a u.fl antenna from my VTX with the clip on the back of the canopy (I've lost no less than 3 antennas that way), so I like the pigtail/sma antenna much better. My wife thinks it looks like Batty Koda from Ferngully (just google it).

  • 176g all-up weight with a 450mah 4S battery
  • 12mm motor mounts
  • 1404 3800kv BetaFPV motors
  • 3x3x3 HQ props -- I was on the fence about these, but I'm really glad I got them. They bite around corners really well without feeling as 'floaty' as I was worried they'd be. Typically I use biblades on my toothpicks but I think i'm switching to HQ after this.
  • I cheaped-out on the RX antenna mounts, but I can't find the mounting retainer for the BetaFPV canopy to use forever tubes. It works though.

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..
