Umm...Building my first Plane

The might Kadet LT-40 ARF... really excited...

question.... are there any tricks to get the pushrod z-bend into the servo without breaking anything??

I'm having a heck of a time

the servo is installed...should I unscrew it, insert the pushrod and then reinstall the servo??

also

I have Futaba S3004 servos... they have a Wheel instead of an arm.....does it matter what hole I put the pushrod in as long as it is even??

Thanks in advance....
