Symptoms observed:

• Aircraft starts normally.
• Aircraft taxis normally.
• At full throttle, both engines briefly respond, then immediately return to idle.
• Torque remains around 8 on both engines.
• RPM remains around 1030 on both engines.
• Both engines behave identically.

Troubleshooting already performed:

• Reset All Failures.
• Set Global Failure Rate to Off.
• Confirmed 0 Active Failures.
• Repaired both engines using the tablet.
• Verified 100% engine condition on both engines.
• Verified battery and aircraft condition appear normal.
• Tried using the Honeycomb Bravo throttles.
• Tried using the virtual cockpit throttles with the mouse.
• Aircraft still produces only idle power.

Additional information:

• Earlier, repairing both engines restored normal takeoff power for one flight.
• On subsequent flights, the problem returned even though the engines still showed 100% condition after repair.
• This appears to affect both engines simultaneously, making me suspect a common system or software issue rather than an individual engine failure.

If this is a known issue or if there is another maintenance or engine-state reset that I should perform, I’d appreciate any guidance.

Thank you.
