Motor MP12090

The MP12090 is brushless DC outrunner which will drive a 36 x 9.5 inch propeller. According to the manufacturer, a thrust of approx. 35 kg at 4600 rpm will be achieved at 70V and ~ 100 A. With a 20 S battery, which can deliver more than 100 A at 74 V, a maximum thrust of approx. 38 kg should be possible, resulting in a total thrust of 228 kg.

Prop

The 36 x 9.5 inch full carbon propeller comes (as the motor and ESC) from the chinese manufactur "FreeRChobby"

ESC

The ESCs are F-22S-380A-A models from "Flier Electronic" from China. The ESCs are designed for a maximum current of 380 amps and should easily be able to cope with the expected 100 A for each motor.

    ESC Features:

    - Battery voltage from 12V to 90V
    - Provides up to 380 A peak
    - Two way communication with computer (USB adapter)
    - Firmware can be upgrade by user.
    - Enables voltage setting the per cell for cut off
    - Reverse function, delay time is adjustable
    - Timing setting can be adjusted (0°-30°) to suit the motor type.

ESC Programming

All settings for the F-22S-380A-A ESC can be made conveniently via software on the computer.
