INDIA'S FIRST
FULLY OPEN
SOURCE
TRI-MODE FCU
Under a unified architecture.
A fully open source tri-mode Flight Control Unit. All in the making by a community of passionate innovators and contributors.
FULLY OPEN SOURCE
Schematics, PCB, firmware, and docs — all open. No locks. No secrets.
TRI-MODE SUPPORT
Fixed Wing, VTOL, Multirotor. One FCU. Any platform.
UNIFIED ARCHITECTURE
One design. Maximum compatibility. Infinite possibilities.
BUILT BY COMMUNITY
By innovators. For innovators. Forever improving.
One FCU. Three Modes.
Infinite possibilities.
FIXED WING
Optimised PID loops for fixed-wing aerodynamics, with full support for traditional rudder, elevator, and aileron configurations.
VTOL
Seamless transition logic between hover and cruise modes. Handles tilt-rotor, tailsitter, and hybrid VTOL configurations.
MULTIROTOR
Proposed multirotor firmware with support for quadcopters, hexacopters and custom frame geometries.
"All three modes. One unified codebase. One community."
FULLY OPEN. FULLY YOURS.
Every schematic, every firmware commit, every PCB layout remains open to the world. Fork it, improve it, build on it. No CLAs. No commercial locks. Just open collaboration. FOREVER.
3D Renders
Visualizing the through-hole prototype board architecture
Top Assembly Render
3D CAD render highlighting the top components placement, including the MCU, sensor array, and high-profile connectors of the Through-Hole (TH) PCB design.
Isometic Assembly
Angled perspective render showing the spatial layout and structural height clearance of the discrete capacitors, headers, and shield components.
Bottom Component Layout
First iteration of TH boards displaying trace routing geometry, ground planes, and bottom-side auxiliary components designed for ease of hand-soldering and community debugging.
