I have bought an innova 550e and have the N680 servos and the N690 for the tail.

I am using a different flybarless gyro (not e-bar) so I need some info on the KDS servos:

1.) What is the N690 centre position pulse length? 960 ，760 ，1520

2.) What is the N690 frequency?- 50hz, 165 ，270，333， 560.

3.) What is the N680 frequency? 50hz, 65 ，120 ， 165 ，200

Thanks for your help, I'm looking forward to my first flight!
