I picked up a new 2018 model. Has anyone had issues with the control arms/turn buckles popping off during normal jumping? Not crashing. Im only doing a 3-5 ft high jump in the grass and have to stop and snap the ball cup back on. It has happend on both sides of the truck but only the inside connection, not on the hub connection. They are loose enough where I can use one finger and pop them on and off. doesn't seem right to me. Any thoughts?
