Sounds like you have assembled it but the propellers and the cages may not be in the correct position. Remember that the gyre has an A propeller and cage and a B propeller and cage. The A propeller and cage should be installed on the left hand side (M side of the Maxspect logo) and the B propeller and cage should be installed on the right side (T side of the maxspect logo). If you mix them up, then you will have exactly the issue you are currently having.
