Well, as i have problems configuring lisa/m to work with 8 motors some months ago i do some test with ppz lpc rotorcraft today.
i used UMARIN board with some mods to work with rotorcraft firmware.
It fly very well in my quad with default i2c values.
When i put the board on hexa frame i need to change the MKK_I2C_SCL_TIME
It work fine with 6 and 7 motors.
When i configure for 8 motor the problem start.
Some time the motors not start, some time it start but when i put some throttle the motor jump to max rpm the stop only when esc time out occur.
Some time the motors start and after some seconds the esc stop due to i2c timeout.
I increased the queue len to 10 and to 20 and problem continue.
I remember that i have similar problem when using LISA but the problem occur even with 6 motor.
PS: all my rotorcraft (quad/hexa/octo) work fine with mikrokopter i2c controller.
I tested the same airframes with lisa and umarin running navgo software

It almost fly, some minor tunnig will be done.
today some few seconds fly, pitch is too low (it need to modify the value), roll is ok, now yaw is in good sens...
Tre propellers are little bit to big... they will be ajusted soon...
Thanks to all,
I don't understand where was my bug.... it is died now!!!
