7uvoK's T'Pel Whoop:

Not a tiny whoop, a T'Pel whoop!
Using Andy Shen's experimental design. Focus is for outdoor speed without having to worry too much about hitting someone. Trying to keep this one family friendly for the front yard or in the park.

First flight review: This thing is pretty fun! It does need to pitch way forward for it to gain ground speed. The self-leveling nature of ducts is noticeable and cool to experience. I had one normal crash that damaged a duct (duct image below, crash at 0:40 in YouTube clip below). That's a little disappointing, but I will get my hands on some of this for repair The motors are getting pretty hot. I wonder if it is a filter setting?

Second day review: Yes, the ducts are delicate. However, its a small price to pay for how fun this thing is! I have been going LOS in Horizon mode and it has been a great experiance. This thing gets enough float and is forgiving enough to let me experiment. I am able to practice power loops and to generally experiment without crashing. This thing makes a great trainer!

Key Features:

  • 4S power.
  • Ducted lift!
  • TBS Smart Audio
  • SmartPort Telemetry
  • Lots of physical dampening

The frame: This was an extremely easy build. Almost seems as spacious as the Martian II. It will be interesting to see how it holds up.
The build: I used an old FC and ESC. It was pre-wired from the previous build, so it was super easy to put together and get set up in Betaflight!
The motors: I used motors that are slightly bigger than Shen's recommendation.

Yesterday evening, I went LOS in horizon mode and just zipped around myself. It was a ton of fun! Its a little slow for FPV to be interesting. Andy Shen considers it a low speed FPV trainer.

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..
