The Kopterworx Big Hammer XB8 ... they claim a payload up to 15kg and flight time up to 1 hour! Built to lift an Arri Alexa!
I know the feeling well. Work all day trying like hell to get it all done before dinner, fail, eat dinner, work some more, finally get all green lights, realize it's nearly midnight, WTF, drive out to the ball field, deploy copter in glow of car headlights, launch, succeed, pack up, go home, sleep well... That was my Monday this week.
No need to stick a gimbal on that thing .... Just strap the camera man to the bottom with his camera. That should resolve the duel TX cross telemetry interference issue with the Graupners
Well this is the only time that we have the time to test and fly them. So tipicaly we do it after midnight. Just too much emails and ppl comming over to talk about phantoms and the sun goes to sleep befoer we can start to do some real work.
