ATLAS – New version

After the disappointment of losing my FlyFishRC Volador 3.5" during a flight without GPS, I wanted to create a new build that I could really trust for both cruising and freestyle.

This new ATLAS weighs 167 grams and is the direct successor of my previous version.
I chose LANNC 1408 3800KV motors, which offer the right balance between agility and efficiency. The electronics are centered around a SpeedyBee F405 AIO flight controller, simple and lightweight, keeping the build compact and reliable.

The frame is still the Atlas 4 LR FPV, strong yet lightweight, now paired with Gemfan 4023-3 propellers for smooth and efficient performance. A GOKU GM10 Mini V3 GPS has also been added to make sure I never repeat the same mistake that cost me my previous quad.

Filters are tuned down to the minimum, and PIDs are pushed a little higher to make the quad sharp and responsive. With 4S 18650 Li-ion packs, the ATLAS combines efficiency, agility, and long flight times without giving up freestyle fun or video quality. I find the 4-inch format especially interesting for endurance and long range when flying with Li-ion packs, making it a perfect compromise between performance and efficiency.

To keep the current draw under control, I use the VBAT Sag Compensation feature at 100% in Betaflight 4.5, which helps avoid exceeding 36A at full throttle. I plan to upgrade soon to Betaflight 4.6 to continue optimizing the setup.
