Our company is looking to get a Cinestar 8. Have experience flying and operating but not building. We have a movi m10 and are looking to use the toad in the hole adapter to connect it to our Cinestar 8. The camera we will be using on it are the Canon 5D Mark III with prime lenses. So the weight of the m10 with the Mark III and prime lens and accessories will be about 10lb. My question is what kind of flight times can I expect with that weight capacity on the Cinestar 8 and When purchasing the copter are the RTF versions of the Cinestar 8 heavy lift going to meet the high expectations or do I need to learn how to build one myself since I may need different motors and parts etc... The RTF version has Tiger 4012 Brushless Motors Blade 350QX Kopter QuadroPower 10,000mAh (6s) Lipo w/ EC5 Connector Technical Properties: Recommended Cameras: Full Frame DSLR, RED, FS 700 Weight Including Motors: ~3050g (6.72 lbs) Dimensions: 1000 x 900 x 350mm Max Payload: ~5445g (12 lbs) Construction: Gen 2 Carbon Fiber Propeller: Tiger Carbon 15x5 MR Is that sufficient to get me 15 minutes of flight time? If I need to build one myself I am a fast learner but I don't learn very well from reading forums, are there any videos you know of or can make to show me what I need to do to build a Cinestar 8. I'm hoping to get 15 minutes of flight time but that may be unrealistic. I see that the Cinestar 8 on Quadrocopter.com shows one battery, can or should it be running two batteries? I realize too the major price difference in building yourself vs purchasing a RTF version, so if it is something I can learn I would like to go that rout but if I am going to be wasting money in trial and error I mine as well get the RTF version. I'd like to get this right the first time.
