    I think he is right zoz.
    Check out the layout of the props in the naza instructions.
    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 have done my maiden tonight in my livingroom.
    Here the first clip I hold the quad in my hand to compare to the next clip flying the thing.
    Make sure you watch it in 1080p.

    I've only got 3 Lipos down here so I can only do single flights between charges. I might have to get some dead weight on the back and use a single LiPo, but that will kill flight times

    I think though, once I've tuned the KK board and move it to between the plates, I'll be able to have the VTX a bit closer to the CG and have less of a lever effect.
    To be honest, I've flown my tricopters and quads with the cg WAY off 80% of the time and the only time I noticed it in flight was when I tried to go full throttle. I'm not saying it's ideal or a long-term solution but in my experience the fc (especially the kk) just deals with it and hides it from you. The front motors will get worked more and get hotter though. Aside from getting bigger batteries... You can put smaller props on the rear motors to move the Center of Thrust to the CG... or put more powerful motors in front.

    Hey Guys,
    Just finished a new video from todays flying at an old mining site in Rosamond, Calif.
    I still am working on trimming the TBS Discovery quadcopter, but the video isn't too bad.
    Enjoy, Keith

    That is true and works for hovering. But if you are moving fast, every thing wil have a influence on the flight caracterisrics.

    this might have been asked before but I am currently building a disco and excited to test it, so please forgive me, where is the best spot to mount the naza gps?

    Cheers

    The position for the naza is marked with a white box. it is also at the same position as the 8 mounting holes for board-like FC's (OP CC, KK ect..)

    Away from stuff that puts out noise. Try to get it away from the vtx and gopro. Most mount it right over the cg on the top plate. I have mine mounted on the lower plate right behind the right rear arm so in a crash it won't get damaged. I have also seen it strapped directly to an arm before

    You should get bigger batteries! Any HK brand will do, I'm liking the Zippy Compact 4000's (4S) for the DISCO these days.

    that's cheating, in the dark jello is not as visible you can tell it flies pretty solid, though, from the way it moves around with all that prop wash in the room. sweet!

    yes, top level right over the CG point is my suggestion.
