RE: Parkzone Spitfire Gearbox Problem
A friend and I have also had trouble with the PZ Spitfire gearboxes. They have been redesigned and ours have hair line cracks that causes the airframe to vibrate when flying. We have determined that the redesigned gearboxes have a cut out for the motor that the old box doesn't have and that is where our gearboxes have failed. I hope Horizon will do away with the redesigned gearboxes and go back to the old gearboxes.
