Five33 TT

The moment I laid eyes on the Tiny Trainer, I was captivated. However, due to its unavailability in my country and the absence of local groups, I never seriously considered purchasing one. Nevertheless, a local TT racing chapter recently emerged, giving me the perfect excuse (although I didn't really need one) to finally get a kit.

Initially, I used a DarwinFPV 1-3s 15a 25 x 25 All-in-One (AIO) setup for the build. Soon enough, I realized that the amp rate fell short. During a corkscrew maneuver, the drone went up in smoke, leading me to opt for a BetaFPV F405 4S 20A FC v5 for the rebuild, as it was the only option available locally.

This build has been the most demanding one I've undertaken, taking considerable time to complete. I wasn't satisfied with the standard TPU part included in the kit, so I took it upon myself to craft my own. Some of the models are remixes, while others are entirely original, such as the tail, which I modeled after the original racer's design. You can find the link to the parts in the provided list.
I meticulously assembled this build, ensuring that all solder joints were fully flown and shimy. For the LEDs, I went a 144/m WS2812B RGB LED Pixel Strip, powered by a Matek 5v BEC connected directly to the V-bat to reduce strain on the FC. If you were to activate a Larson scanner on the LEDs, they would run from the tail to the nose, extending on the arms to the motors, and back. I've configured the race colours to be controlled by a trim switch, allowing me to change the VTX Channel along with the corresponding colour in one profile. Additionally, I've used a potentiometer in another profile to access the full spectrum of colours.

This will be my first-time racing, so it should be interesting!

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..
