The QR-1 is out of trim. Correct by using the trim buttons on the transmitter. If your QR-1 pulls or drifts in any direction (unrelated to air currents) when the sticks are at neutral, you can use the trim controls to tune out any unwanted flight motions. Make sure the QR-1 is in a draft-free area at least 3 feet off the ground before adjusting the trim. The trim buttons will adjust each control in a small increment with each 'click'. Press the trim button as many times as is required until the model holds a steady hover with little or no correction required. The stabilization system needs to be reset.
