Introducing the TANQ S 3.5" by Let's Fly RC, a versatile and durable FPV frame designed to meet the highest standards. The TANQ S supports the DJI O3 and Walksnail Moonlight systems. It delivers GoPro-like quality footage without any props or frame in view, even with the widest setting, all while protecting the camera. The TANQ S 3.5" matches the flight performance of a 5" frame and lives up to the TANQ name in terms of durability.
