5 Frequently Asked Questions
Can I take still photos with this model?
The unit focuses primarily on continuous video recording rather than still imaging. Verified specifications confirm video capture resolution without photo functionality.
Does the controller need separate batteries?
No. The transmitter charges entirely through the provided USB link. Verified shipping contents list a single USB cable for direct tethering.
Will it survive tree branches?
The lightweight shell handles light contact but requires careful navigation. Outdoor use suggests avoiding dense vegetation due to the fifteen meter per second speed limit.
Is professional experience necessary?
Designers engineered the interface to help beginners master basics quickly. Ready-to-go status removes complex soldering or hardware pairing steps.
What replaces GPS outside?
Ground tracking cameras measure surface shifts to freeze position indoors. Optical flow technology compensates for satellite absence during low altitude flights.
