  3. Hello, I have acquired one of your "6 CHANNEL MULTI-FUNCTIONAL BRUSHLESS VERTICAL TAKE OFF and LANDING STUNT" models. I am very interested in the PCB and transmitter combination and the use of the 6-axis gyro in another project I am developing. The flight parameters are similar in that it will be capable of multirotor flight and airplane flight. However, I will require higher currents than presently possible with the M02 PCB, probably 45 A peak and 25 A continuous current. I would be very appreciative of any guidance you could provide regarding current capability of the output from PCB to ESC, or whether modifications to the PCB are possible with a supply agreement,. Thank you for your consideration.

    Kind regards,
    James Marcicki

  6. Dear Sirs,
    I have a technical problem with my drone. After flying several times successfully, suddenly there is no communication between Remote control and fly unit.
    After switch on the drone and the remote unit, the lights of the drone are flashing like the headless mode (quick flashing blue lights for three times, followed by quick flashing green lights for three times, and repeat this secuence again and again.
    And the drone doesn't react to the remote control. Is like there is no communication between the drone and the remote control unit.
    Of course, batteries are fully charge.
    I don't know how I can restablish this communication. On the other hand it doesn't appear the manual for this model on your web.
    Please, could you be so nice for helping me...?
    Thank you in advance for your help.
