Hi,
That library appears to reset timer1 in which case you cannot use it with the Arduino Servo library - which limits its use.
I have an alternative library which reads PPM and controls servos, there is an example sketch for 3 channels, but if you want to use it with 8 or 9 I would be happy to send you a template sketch.
At the moment the failsafe has been left to the user to code in the loop function, as I generally end up writing the same code for this, I will move it into the library.
Let me know if you want to give this a go, you can see the library in use in the link.
