Going for a lightweight long-range 5-inch. Originally mocked up with AOS Supernovas but I could not fit an appropriately sized ESC into this frame. Switched the motors to Emax Eco II 2004 1600kv, which seem to be a much better match for the project. I'm going to fit Gemfan 5" lightweight bi-blades (LR 5126-2).

The build came together nicely once the motors and stack arrived. The Flywoo stack was wonderful to work with and I took full advantage of the plugs on the FC to connect the GPS and RX. This was my first experience with AM32 - no issues so far. It's interesting hearing totally different startup sounds as I have only ever had BLHeli before!

GPS is mounted at the front to avoid interference from the O3. I remixed a 3D model that allows the GPS to be mounted to the horizontal standoff at the top of the camera cage. This works perfectly, and I get 12+ satellites right away.

As I got near the end of the build, I decided to mount the battery in the 'toilet tank' fashion just for variety. It turns out this orientation was a better way to mount the bigger 18650 pack.

Here's the maiden flight:

It flies very smooth with Chris Rosser's tune for this frame.

Update: switched battery strap to normal. I got a 25 minute flight with a 6s1p 3000mah li-ion pack.

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..
