Hello . Trying to set ups the new model with 8 thrusters . after configure to a big platform .  
I can not get a signal out on Channel 8 for thruster . Have tried to switch connector on 2 thrusters . And all work .  
But it seems that the signal does not come out of port nr 8 . Any tips ?  
Regards Danne

Check the parameter value of SERVO8\_FUNCTION, it should be assigned to motor 8, you may have a conflicting assignment like the camera. Make sure the camera tilt is assigned to a different channel on the camera page. Or, you can load the parameter file contained in the heavy setup documentation: [BlueROV2 Heavy Retrofit Assembly Tutorial](http://docs.bluerobotics.com/brov2-heavy/#software-setup)
