TanQ S 3.5 Pro Spec Built and Tuned FPV Drone by Lets Fly RC

Description

All of our Built & Tuned drones are carefully assembled in the USA by our expert team. Each drone is fully tested, tuned, and verified for reliability before shipping, so you can fly with confidence straight out of the box. No extra setup, no guesswork—just a drone that works as expected from day one.

Meet the TANQ S 3.5" by Let's Fly RC—a compact yet rugged FPV frame that embodies strength, versatility, and performance. Built to handle demanding flights, this frame is compatible with both DJI O3 and Walksnail Moonlight systems. It delivers cinematic-quality footage comparable to a GoPro, with no propellers or frame edges in view—even when shooting in ultra-wide mode—while keeping your camera safely protected.

The TANQ S 3.5" rivals the flight characteristics of a traditional 5" frame, bringing powerful performance in a smaller package. Staying true to the TANQ name, it offers unmatched durability in its class.

Note: The Pro-Spec build weighs over 250 grams for increased strength. You can fine-tune the weight by switching to a lighter battery, minimizing TPU components, or using slimmer straps to match your flying style.
