I discovered that Multiwii version 2.3 and newer have had a default pin 
reassignment. Servos on older versions were defaulted to SW_PWM but the new 
default is HW_PWM. I believe pin 2 under SW_PWM would be assigned to pin 12 
under HW_PWM. Some mega boards don't have a pin 12 so the option left is to 
assign servos to SW_PWM, which should make pin 2 operative.
