    Yea, X8 would be definetly enough for my cams but thinking that if I just get the extra 2 motors and build coax hex then I could offer the chance of lifting a Red..And that would be great!!!

    Depending on how you build it, a Coax X8 could lift a small car:D

    Basic version: 15lbs payload


    Extreme version: 44lbs payload

    OMG!Thats crazy geaar!!!
    If I had the funds I would probably go for something like that, X8 just looks so neat,easy transport etc...
    But limited to 13-14 props by MK bl and motors I think the cheap way to go is geting 2 extra motors..
    Like this video,can you guys identificate the gear? Seams like MK electronics and apc 13 65 E props..is that cinestar gimbal?

    Yes, they're flying MK electronics with 13x6.5" props. They're using a custom gimbal not a Cinstar.

    Looks everything is custom made, but with lots of Cinestar inspiration on many birds though ;-)

    Scroll down to bottom of news page;

    Thanks Howard!
    I did all the mixing and superficial test with coptertools and everything seams ok...I loaded X4 and aplied 8 motors with that mixer setup.Is that ok?
    I was going to go test it now and so I turn it on and get the alarm for no Tx..
    There is conection between Tx and Rx
    Im even geting telemetry.
    Checked koptertools, Im on Graupner Hott. Solder on Fc Ok...:mad: and I just tried it 5 minuts ago and it was all good!

    Found it:
    NFO - SUMO 12 Setting
    If you hold down the button (accidentally) at the receiver while connecting, the "SUMO 12" setting will be deleted. This can be also happen if you connect the receiver with a powered up Mikrokopter and hold down the button. In this case you have to set this setting again.

    If you don't have a number behind SUMO, you have to update the transmitter. How to update the transmitter you can see here: Update

    Cheers,

    Hi!! So:
    -Copter:
    X8 custom frame aluminum 1.5x1.5 arms and CF center plate,78cm rotor to rotor.
    Mk electronics and motors(3638) with SF 12x38 APC props top and botom.
    PID: 100/120/15
    sticks: at 4.
    -Camera & Gimbal:
    CX 730 and MK HS2.
    -Flight and BL temps
    09`27min on 2x4000 4s 40c Turnigy bats- Total Mah 6845.
    Max Bl temps 78C / Air temp 16C . the Dome just has a hole in the top.
    Cant get hand on a scale...
    -First impresions:
    It still doesnt feel as stable and solid as flat configuration. I feel that the Fc overcomes the stic imput, when I want to fly in any direction I need to increase constantly stick to mantain flight angle.
    Its not as wobbly as flat descending but still needs twiching.
    Lacs solidicity(is that word correct¿¡?)..
    It sound great, like if the vibrations were much less,sounds softer
    I have some CF13x65 around, should I combine? If so, should I level the mixer to the same values?
    Any sugestions are very well come!
    I,m sorry on the presentation of the little punk, just testing for now..
    Regards,
    Alex

    TEST 2
    Changed the props to 13x65 CF top and botom.
    PID: 100/120/10
    sticks: at N8-R6-Y6.
    -Camera & Gimbal:
    CX 730 and MK HS2.
    -Flight and BL temps
    11min on 2x4000 4s 40c Turnigy bats- Total Mah 7000
    Max Bl temps 102C(BL7) rest 65 avarage / Air temp 16C .
    -First impresions:
    Much more stable, good enough to shoot with now! It still needs some fine tunning so it runs smoother for AP..
    Props seam to be more efective as this time I pulled out 11min! also consumed a bit further to 7000mha..I gotmy low batery alarm set at 3.6v x cell.
    Going to check that Bl as its runninbg 30C above the avarage..kopter is balanced by the way..
    Regards,
    Alex

    Yep, you're getting there. 13" - 15" are definitely the way to go. Not enough lift with 12"

    For kicks, try my settings with your rig. I have it set to fly calm and smooth...not so reactive to stick input (not jumpy). I don't use a compass or GPS. My payload weighs approx 3200g...gimbal+camera/lens/electronics etc. My motor KV are a little higher than yours so that may make a difference in perfromance.
    [Gyro]
    P=103
    I=120
    D=13
    Gier_P=100
    Gier_I=120
    DynamicStability=62
    ACC_Gyro-Factor=27
    ACC_Gyro-Compensation=50
    DriftCompensation=0
    Stability=6
    Main-I=16
    MotorSmooth=0
