F1E Control Unit – Version 2026

For all three hardware platforms

What’s New at a Glance

Version 2026 introduces a fully redesigned calibration system, delivering faster startup and improved flight stability.

Fast Startup – No More Waiting

• Sensor offsets are permanently stored
• Immediately available after power-on
• Ready for operation within approx. 10 seconds
• No more “figure-eight” magnetic calibration required 
• If necessary:

 → Simply move the model briefly through the air to complete magnetic refinement.

More Stable Flight Performance

• More consistent stabilization
• Improved directional accuracy
• Reproducible behavior across multiple flights

Enhanced Status Display

An optional plug-in display now shows:

• Startup progress
• Calibration status
• Diagnostic information

Simplified LED Logic

• Yellow LED ON permanent → Calibration not yet completed
• Yellow LED OFF → System ready for operation

Important After Firmware Update

If performing a firmware update yourself:

• A one-time full pre-calibration must be executed.
• The procedure is described in the document “Calibration manual.”

All newly delivered control units are already pre-calibrated.
