It has come to our attention that there is potential for the Babyhawk R to experience a short on the frame due to the 4in1 ESC coming in contact with the frame. From the factory, the Babyhawk R comes with stack pre installed with rubber grommets that float the stack at 2mm away from the frame(which keeps the capacitors at 1.2mm away from the frame). If the four screws that hold the stack are over-tightened, the stack gets extremely close to the frame which can make the capacitors come in contact with the frame.
When tightening the stack screws, please be aware of the spacing between the 4in1 and the frame. For good measure, we recommend checking the spacing between the stack and the frame after each flight.
