Condition: One brand new, one lightly used — both fully functional

Selling a pair of YSIDO NEW F4 V3S PLUS flight controllers — one never used, the other lightly flown and in great working condition. These are budget-friendly but reliable FCs that support both Betaflight and INAV, making them a solid choice for entry-level builds, backups, or basic long-range drones.

Key Features:

* F4 processor – Capable and responsive for standard Betaflight/INAV builds

* INAV & Betaflight compatible – Great flexibility for both autonomous and freestyle setups

* Compact design – Ideal for tight builds or sub-250g frames

* Straightforward wiring – User-friendly layout for faster setup

* Good for 3–6S builds depending on paired ESC (check specs)

These are great options if you're just starting out, building on a budget, or want spare FCs for prototyping or experimenting with INAV features.

Only asking $20 for both units — a great value for someone looking to get flying or add backups to their bench.

Local pickup preferred (Southern NH / Boston area), but I’m happy to discuss shipping if needed.

Message me with any questions or if you want photos or specs!

Price: $40 each or $70 for both

Condition: Fully working and well-maintained

Selling two Holybro Kakute H7 V1.3 Flight Controllers — both in excellent working condition. These are powerful, reliable FCs with premium specs, ideal for advanced Betaflight, ArduPilot, or INAV builds.

Key Features:

* H7 processor (STM32H743) – Tons of processing power for complex missions and advanced filtering

* MPU6000 gyro – Stable and noise-resistant IMU, ideal for smooth flight performance

* 2–8S input – Compatible with a wide range of power systems

* Built-in Bluetooth – Wireless configuration via SpeedyBee app (or similar)

* 30x30mm mounting pattern – Standard fit for most freestyle and long-range frames

* ArduPilot & Betaflight compatible – Great flexibility for custom builds

I originally used them for ArduPilot projects, but I’ve since moved to using MicroAir FCs for my builds and no longer need these. Would love to pass them on to someone who needs a solid H7 FC for their next project.

Perfect for high-performance quads, autonomous builds, or anyone looking to upgrade from F4 or F7-based boards.

Local pickup preferred (Southern NH / Boston area), but I’m open to shipping if needed.

Selling a brand new, unopened SpeedyBee F405 V4 flight controller stack — never mounted or powered. This is a powerful and reliable FC/ESC combo that’s ideal for building high-performance racing or freestyle drones.

What’s included:

* SpeedyBee F405 V4 FC – Supports Betaflight & INAV, Bluetooth for wireless tuning, onboard 16MB Blackbox, up to 8 motor outputs, and plug-and-play DJI support.

* 60A 3–6S BLHeli_S 4-in-1 ESC – Current-rated to handle aggressive 5” builds, with smooth throttle response and solid reliability.

* Mounting pattern: 30x30mm

* Firmware: Betaflight / BLHeli_S compatible

* Condition: Factory sealed, never opened

I picked this up during the recent price spikes caused by import tariffs, so I’m selling it for less than I paid — just hoping it finds a good home. I originally planned to use it for a custom build, but ended up taking a different route with my FPV setup.

Local sales preferred — Southern NH or Boston area.

If I don’t get any bites in the next couple of weeks, I may just keep it for a future build. But if it helps someone get started or upgrade their FPV rig, feel free to reach out!

** I will include another used Speedybee F405V4 FC for an additional $20 if you want to have a backup FC. **

Selling my RadioMaster Zorro, a compact and feature-packed radio controller that has been my go-to for daily flying. It’s lightly used and well cared for — all buttons, gimbals, and switches work perfectly.

Key Features:

* EdgeTX-ready – Fully customizable interface with regular updates and community support

* Compact gamepad-style design – Great ergonomics and portability for FPV pilots

* Internal ExpressLRS module (or Crossfire/4-in-1, depending on version) – Reliable long-range and low-latency performance

* Built-in 18650 battery support – USB-C charging for convenience

* Large LCD screen & intuitive layout – Quick model switching and easy navigation

This controller is ideal for freestyle, racing, or long-range flying. It’s been a reliable part of my setup, but I’m changing systems and no longer need it.

I've had it for less than 5 months, and it's in perfect working condition. If you'd like, I can leave all the current configurations on it so you can take advantage of the custom logic I built into the models. It includes a Betaflight setup and a more advanced ArduPilot configuration with extra options.

I'm also including a carrying case to help keep it safe during storage or transport.

Local pickup preferred (Southern NH / Boston area), but shipping can be arranged.
