Hi good morning Matt,
Thank you for the detailed description and video, this does help us with trouble shooting.
I think it might still be trying to calibrate the gyro which control the surfaces.
Reflex gyro still in its 30 s start-up routine – until the gyro finishes calibrating, the elevator, aileron and rudder channels stay locked. You’ll see the LED on the gyro flashing rapidly; once it goes solid the surfaces should respond. Leaving the model absolutely still and level for 25-30 seconds after plugging in the flight-battery normally clears this.
This is a thread from a customer who experienced a similar issue, I think this might be the problem:
Please let me know if that sorts out the issue? If not I will contact the manufacturer and ask for further assistance.
Hope this helps.
Regards,
David
