My son was super excited to put this together. He lost the propeller in day 1. Is there any way to get a replacement propeller?

Please contact the seller for replacement pieces.

The wires on the helicopter do not match? We have red/black and green/black. This is the second one my son has built that does not work.

Connect the red wire with the red wire and the green wire with the black wire, as shown in the video. We apologize for not updating the instructions in time when the production batch changes. Thank you for your feedback, and we’ll make corresponding improvements. If it still doesn't work or you have any problems, please feel free to contact us. We’ll try our best to solve them.

How are the wires attached ?

Video of Wire to Motor Note that the actual direction of the link between the motor and the wires should be based on the instruction manual.
