In this guide, we will walk you through the essential process of flashing and updating the Betaflight firmware on your FPV drone’s flight controller (FC). Whether you are looking for new features or bug fixes, this tutorial covers the steps, potential pitfalls, and troubleshooting tips to get you back in the air safely. Note: Flashing firmware often wipes your existing…
 3rd August 2025  Choosing a radio transmitter for FPV drones can be overwhelming for beginners with so many options available. A radio transmitter is critical to controlling your drone in flight. This guide explains factors beyond price, such as supported frequency and protocols, channels, functionality, reliability, comfort, and software.    Some of the links on this…
At the Atom Aviation R&D Lab, we are constantly pushing the envelope of what unmanned systems can achieve. While GPS navigation is standard for outdoor long-range missions, true autonomy requires robust performance in “GPS-denied” environments—indoors, under heavy canopy, or in urban canyons. As an Electronics and Communication Engineer, I approach this challenge not just as a pilot, but as a…
Here at the Atom Aviation R&D lab, we spend a massive amount of time optimizing link budgets and testing UAV reliability. One protocol that has completely taken over our workbenches recently is ExpressLRS (ELRS). However, the ELRS hardware ecosystem has exploded. We went from a few open-source designs to a market flooded with diversity, dual-band, Gemini, and TCXO options. As…
If you’ve been following the hardware stack market recently, you’ve probably noticed the legendary SpeedyBee F405 V4 has been impossible to find. As someone who has integrated the V4 into countless test rigs here at Atom Aviation, I had a feeling something new was on the silicon horizon. Well, the SpeedyBee F405 V5 is officially here. Coming from a B.Tech…
