Any suggestions?
Thanks,

What BEC are you using? I don't see how voltage could be the problem. If I remember correctly the servos you mentioned are rated for between 4.8 and 6 volts. However, these servos draw a lot of current, and that will cause your receiver to glitch if your BEC is not up to the task. A 3 amp external BEC might do the trick, but the Castle BEC is even better since it can handle more current draw and the voltage is adjustable.
