    My video was just to show how much the copter shake, the gimbal isn´t the problem. just the copter shake so much... when you park the copter at one place in the air it will shake always al little bit. When you fly straight up in the air it is heavy

    It isnt a problem from the gimbal, the copter shakes so much. when i stay at one point it ist a little bit a few centimeter but, for example, when i fly straight forward it is so much bigger. I never had problems with mikrokopter and i think wookong usaly also didn't hase these problems

    Ok Philipp, i unterstand your problem... Change your ESC and fly with Reflashed SimonK' s ESC. These maytech aren't for "multi" use, only Castle Creation or SimonK reflashed ESC are really optimised for Multi-Rotors...(WKM Users....):cool:

    Look at this video and you will unterstand what i mean...

    There is not a special problem with your ESC Program but i tell you again Maytech, Turnigy, Hobbywing and others aren't well made to run for multi-rotors.
    I have try ESC like Maytech, Turnigy plush...With Wookong-M and no others execpt "Castle Creation ESC" give far far better résult than Reflashed SimonK ESC, if you run 12 poles motors these just give you perfect results with DJI Autopilot system.:cool:
    The Flashed ESC have no need to be programed, they have just a perfect linear curve response from 0 to 100% power, wookong do the rest...:)

    Hi Guys,

    today i have calibrate my throttle position and now the kopter sound very divergent. The Motors are spinning not so much when i start.
    Also the ist the problem that the copter is shaky. I think it is not so much but specially when i fly backwards and down.

    I think the copter is after the calibration more stable but not enough.
    Her is again the picture of my esc config. it is right that the timing is "low" i use QC3328 Motors

    Thanks ahead

    Hi Philipp, Im using the same Maytech 40A V1 optos on a new cs8 build.. mine are set to high timing & cut off voltage at 2.8v, at 16khz, (you have to go through the tx menu to find the 16khz setting ).. working great on the bench but not had it in the air yet, but im running 14pole 3515/400kv motors. Waiting for my replacement WKM MC before i can commence flight testing.

    Hello WKM / CS8 users,

    I'm looking for some help and guidance.
    After 3 very bad (and .GXP unexplained ) crashes... I'm also looking to divest our CS8 from the Mikrokopter electronics, and move to the DJI-WKM I have on our shelf. My plan is to keep the CS8 frame and parts.
    • Phoenix Ice Lite 50a or SimonK Multicopter Speed Controller ESC 40A ( but was looking at Red Brick 70A Flashed SimonK)
    • New 4mm motor wire connectors needed ? What do you use ?
    • WK-M single waypoint ( for now )
    • 2 paralleled 6200mAh 4s packs ( we have 10 batts)
    • QuadroCopter QC-3328 motors (for now).
    • APC 14x4.7 props (have19 in stock) until we switch to XOAR 14x5 (or 12x5 pending motor upgrades)
    • 360/Radian/2nd user ( independent system of course)
    Check out the custom lasercut plexi ( soon to be CF ) mounting plate for CS8 to WK-M.
    IMU is perfectly centered, Compass is 130mm back off Vertical, on Horizontal centerline.
    Took about 25-30min to draw them up in Rhino3d, Then sent them over to my Lasercutter, had parts in hand in less than 3 hours. Next version will also have CS6 mounts.

    Can you please explain the "esc config jumper board" below ? ( forgive me, I think i missed some info)

    Thanks in advance
