servo problem..pls help

[hus09truggy]

Hello, I bought a new receiver battery (Orion marathon 1600mah) to power my servos on my hong nor truggy. I first discharged it and then fully charged it. When I switch everything on, my savox servo 10.5kg for the throttle starts to shake fast but small distance. I've also centred it. But my steering servo is fine. And also sometimes when I hit full throttle the failsafe kicks in for second and then lets go. What should I do?
Its my first time I have installed a rechargable batteries. thanks!

and also when i brake and press the throttle it does not shake (vibrate)

I would see about cycling the rx pack through 3 or 4 charge/discharge cycles to wake the battery up and then try running the buggy again.

Sounds like a weak charge, bad contact or bad cell in your pack. Try what hamz said and see if that makes things work right.
