FIRSTLEGENDS at checkout.The Hummingbird 200 RaceSpec Stack is a purpose-built 20x20 flight stack designed from the ground up for competitive 5” FPV racing. Co-developed with professional racer Kyle Buell (aka Twidgit) and tested rigorously over half a year of real racing conditions, this stack delivers the durability, precision, and simplicity that race pilots demand.
At the heart of the system is the Hummingbird 200 Flight Controller, powered by a blazing-fast AT32F435 MCU at 288MHz, offering performance that surpasses even F722 processors. It features the highly respected ICM-42688 gyro with dedicated LDO power, and a built-in UART-based ExpressLRS 2.4GHz receiver with dual ceramic patch antennas and a TCXO oscillator for unmatched signal stability. This design eliminates the need for external receivers, simplifying builds and improving reliability during crashes.
Paired with the FC is the Hummingbird 200 4in1 ESC, rated for 80A continuous and 100A burst per channel, supporting 3–6S LiPo input. Built on a 6-layer 3oz copper PCB with blind vias and gold plating, this ESC is engineered to survive repeated abuse. It features three massive onboard TVS diodes for voltage spike protection and four corner-mounted capacitor pads for larger builds.
A standout feature is the 3D reinforced motor pad design—with solderable surfaces on the top, bottom, and side—ensuring rock-solid motor wire attachment that won’t rip off even in hard crashes.
Priced at just $99, this stack shatters expectations, offering elite-level performance and racer-driven durability at a fraction of the market price. Built by racers, for racers.
