I am interested in purchasing an ArduCopter 3DR Hexa or 3DR ArduCopter Quad-C from Udrones. The primary purpose of the ArduCopter will be filming for action sports. I have a few questions before I order my first UAV:
Thanks so much,
1) We strongly recommend you also use RC gear as safety measure, so you can always regain manual control
2) You don't need sonar. It will do it fine with the standard APM 2.x board using the baro sensor
3) Hexas can carry heavier payloads (such as larger cameras)
4) It depends on what kind of battery you use, but 15-20mins is reasonable.
I am a newbie here, but I'll give it a shot.
