I have a good deal on these servos, will they work on my Raptor Titan for collective and cyclic. My second question is how do I regulate my tail servo voltage as I have to run the 3050's on 6v and the tail on 5v. I can not find any voltage regulators at my LHS so I was wondering if I could build my own does anyone have circuit diagrams?

Are running a regulated 6V or just a 5 cell pack?
It makes a difference how you do this.

I was told I could run to fat diodes which were given to me to fit on the positive conductor. It brings the voltage down by 1 volt. Can I run these servos on 4.5 volts if need be. I will eventually import a UBEC or seperate BEC, but for now I just want to run the motor in. Are these servos up to the task?
Thank you

If you want to spend the money, fromeco.org has the Arizona regulator. It is a duel voltage regulator sending 5v to the gyro and adjustable voltage(up to 6v) to the receiver and cyclic servos.
I just bought the Align step down regulator from the local shop in Beijing. Very simple, plug the step down in plug to the receiver out (or the control unit out should you are using GY611) and the other end (the regulator out) to the servo and here you go. The step down comes with those standard plugs and you don't need to do any additional wiring but to plug in and fly. Hope it helps.

You'd be better off to use something like was mentioned, the Align step-down regulator http://grandrc.com/inc/sdetail/60060
A diode drops voltage by 0.7V, but it will always drop it by that voltage, so as your battery declines, so does the voltage available to your tail servo. A regulator will put out 5.1V until the source drops below that. As well, a fully charged 5cell pack will be above 6V on a fresh charge, subjecting your 4.8V tail servo to 5.5V or more with a diode. A regulator costs $4 or so, how much does a S9254 cost?
