drive questions.

I am very happy today, I managed to get the clucth to work. I built a small board (mosfet) with the information you gave me. The only problem is that I have to use Timo Birnschein's motor.ino and modify it a bit by Andreas29. Pin 11 is not defined in the motor.ino. I use ''ENGAGE_LED_PIN 7 // led is on when engaged'' to engage the clutch. So I don't have access to the PI function for pin 11. I also can't confirm if the different servo settings are calibratable.  
I tried to change pin 7 of the motor.ino for pin 11 in pins.have a definition but it doesn't work, it doesn't change state. What do you think? What should I do to use the latest motor.ino and not have badvoltage_fault? Or use Timo's motor.ino with pin11? or not? or use the last one?
Also if I use the latest motor.ino, I get a badvoltage error because Andreas' design board probably does not use the same resistor for shuts! and even if I disable the current sensor. 
I tried to change pin 7 of the .ino motor to pin 11 in pin.h but it doesn't work, it doesn't change state.     
What do you think? What should I do to use the latest .ino motor and not have badvoltage_fault?  Or use the timo motor.ino with pin11?
I think the driver will be usable in this configuration.

Thanks for your help

As Sean says if you want pwm need to use pin 11.
It will also pull in clutch while motor is running in standby mode.
As I recall soldered wire directly to Arduino pin on the motor controller pcb.  Use small stranded wire and try to provide some sort of strain relief. Maybe a dab of silicone. Was not that happy with solution but it is working. That's why I'm asking questions about the new motor controller :-)
If you really want to use another pin I have schematic and program to use tiny85 to do pwm. 


I'd try to get the new motor.ino using pin11 to work but you may have to make some changes.
I'm using a cheap rudder position indicator. Works fine but was challenging to install.
