    Multirotor Endurance and setup...

    It seems that the biggest problem with multi-rotors is flight time... What are you flying and how long can it fly?

    1. Platform (Tri, Quad, Hex, Octo)
    2. AUW (ready to punch the throttle and take off)
    3. Motors (model and kv rating)
    4. Propellers being used (manufacturer, diameter, and pitch)
    4. Battery (manufacturer, capacity, and C rating)

    Post a pic or video too!

    interesting, looking forward to some entries. i think hovering current would be a very interesting number regarding endurance. here's mine

    hobbyking q450 quad. auw: 1160 grams (with metal cased pixim). kd 20-22L motors, 920kv. 8x4.5 or 9x4.7 from hobbyking, labeled gemfan. currently 4500mah 30C zippy, or old rhino 5000mah 20C (both 3s). hobbyking blueseries/mystery 12A esc with simons firmware. hovering current 12-13 with 8x4.5, and around 1 amp more with 9x4.7. farthest distance flown 2.0km, used 1.5Ah for out and back, rc link is the limit. it flies around 10-15 minutes, never really measured it...


    video was made before i exchanged the gopro with a pixim, and 8x4.5 props, now 9x4.7 (because i ran out of 8x4.5 ones )

    I have a 2.5-style Tricopter, it's pretty heavy at 1275g. That's because I'm keeping my GoPro sealed intact in the case, and my FPV cam is also in a case. Motors are Hextronik DT750's 750kv, props GWS 10x4.7 (tried 11x4.7's for easier lifting of the weight, but I wasn't happy with the balance). Batteries are Turnigy 2200 3S 25C.

    This is my first flying platform, and first FPV setup, so I started bare bones and added on little by little. As a plain Tricopter carrying a light recording camera and nothing else, she managed 12 minutes or so. Full loaded as she is now, hover time is somewhere between 8 and 9 minutes, but I set my timer for 6 minutes to have a bit of a safety margin.

    I'd be interested to know if people are taking bigger batteries up on Tricopters. I've tried 2 x 2200's in parallel, so I know it will lift it, I'm just not sure what the good sweet spot might be between size and weight

    CurryKitten: Is that Tri-copter the RCexplorer.se build? If so, what mods, if any, did you make to it?
    Airplanes LIKE to fly : Helicopters WANT to kill you.

    Yep. It's almost a straight copy, with dt750 motors, 18a plush ESCs, and gws 10x4.7 props, with a KK board. So the only thing I did is start weighing it down with more stuff. Fpv camera in case, GoPro 2, 5.8Ghz vtx, suppo osd, microphone and slight dodgy landing gear

    How many engineers does it take to change a light bulb?
    3. One to hold the light bulb and two to turn the ladder.

    I was using a bunch of 2200 3s on my quad and then used the 3300 3s from RMRC and my flight times went from 4-6 mins to 8-10 mins and the flight performance was great still. I tried a 3s 5000 and it was too much it seemed to me and burned out around 7 minutes if I remember correctly. Motors were hot too.
