How do you download videos and look at throgh the camra on the helicopter?

Thank you for your question. From my research, it appears that the Air Hogs R/C Reflex does not have video capabilities. The Air Hogs Hawk Eye does have video and picture taking capabilities. Look at your Air Hog to determine which one you in fact have. Here is a link to video tutorials for all of the Air Hog products that may help you: http://www.airhogs.com/#/need_help/reflex. The link is set to the Reflex but you can change your product selection to any product at this link.
If you have the Hawk Eye, here is a link to the instructions: http://www.spinmaster.com/files/instructions/AH_Hawk_Eye.pdf. It is not possible to look through the camera. You can however, take pictures and videos during flight. Download the images on your computer to see the images you caught. To download, plug the small end on the USB plug (included with your Air Hog) to the product and the large end to your computers USB plug (this is how you charge the Air Hog, too). In your computer's Windows Explorer, you will see your Air Hog connected and can copy the images to the computer. Remember to remove the images from the Air Hog to free up space for new images. Always remember to pick on the eject button on your computer for the Air Hog before unplugging it from the computer. Take note that the videos do not record sound. If you access www.airhogs.com, you can register and download free editing software to add cool images, sounds and words to your videos and pictures. You will also be able to share them with others.
If you need additional assistance, you can contact Air Hogs Flight Training Center at 1-800-622-8339.
I hope this helped. I would appreciate your taking the time to rate my assistance with FixYa. Enjoy your flight!
