Used Original InterLink controllers for G5.5 are selling on eBay for $80 to $150. That is absurd for a peripheral that uses decade-old potentiometer gimbals (which drift and jitter).

The Emulator Advantage: An emulator is free (or available for a negligible donation to the developer). Pair it with a $30 FlySky FS-i6 or a $5 USB SIM dongle for your existing radio. You effectively save $100+ while getting superior hardware.

Even if you own the original DVD, reinstalling G5.5 on Windows 10 or 11 often results in driver conflicts. Microsoft’s updated USB stack sometimes fails to recognize the old InterLink’s chipset. Consequently, users are left with expensive software they cannot run.

The RealFlight InterLink controller feels like a toy. It has light, springy sticks and cheap switches. If you train on a $300 Spektrum NX8 or a high-end Radiomaster TX16S, moving back to the InterLink introduces "muscle memory confusion."

The Emulator Advantage: With a dongle emulator, you fly RealFlight G5.5 using your actual field transmitter. You practice with the exact stick tension, gimbal throw, and switch placement you will use at the flying field. That is better training, period.

Knife Edge Software (now RealFlight) has moved on to G7, G9, and Evolution. They no longer support G5, and they don't sell the dongles anymore.

Legality: You should own a valid, physical copy of RealFlight G5 (the discs or a digital receipt) before using an emulator. The emulator is a tool to preserve your ability to use software you paid for when the original hardware fails—not a free pass to piracy.

RealFlight G5.5 originally shipped with a custom InterLink controller. This wasn't just a gaming joystick; it contained a proprietary microcontroller that acted as a USB dongle. The software would periodically check for this specific hardware signature. If the dongle wasn't present, the software refused to launch.

The original RealFlight G5.5 was released in the Windows 7/XP era. The physical dongle relies on a legacy driver that Microsoft deprecated years ago. Getting the dongle to work on a modern gaming laptop often requires disabling driver signature enforcement or running virtual machines.

The Emulator Advantage: Emulators run at the software layer, not the kernel driver layer. They work seamlessly on Windows 10, Windows 11, and even Linux via Wine. No "Code 52" errors. No unsigned driver warnings.

You don't need to pack a bulky InterLink. Install the emulator on a USB stick, carry just your laptop and a compact USB gamepad or your field transmitter. Practice at a hotel or lunch break without hauling extra gear.
