8V BeastX Setup's

Hi all,

Are any of you guys or girls running your BeastX on 8v?? I'd like to run mine on 8v, but not sure if I'd need to get a step-down for the tail servo... I'm using an AR7100 RX, which has the "built in" step-down for the gyro, but will that still step it down for the Beast's tail gyro??

So if I pulg the Gyro and Gain wire into the regulated side of my RX, woud that regulate it for the beast?? Or does the beast get all it's power from one of the cyclic channels??

As far as I know, the Tail gyro in the Beast is seperate to the cyclic gyro's... So therefor, it should be 5.2 in through the Gyro lead and 5.2 out? Am I right?

There is a wiring diagram on this site somewhere, showing how you can split the wire to get the signal from the Beast X but supply the power from the regulated side of you AR7100.

Used to run mine, but after concerns of DS610's not enjoying running at higher voltages and frequencies, I put an inline Perfect Reg in place, so everything is now getting 6v.

shaun what you have to do if your not running a align or hv tail servo is split the power to the tail servo as the beast runs at cyclic voltage so you have only the signal lead from the beast to the tail servo and the 5.2 voltage + and - from the ar7100 to the power of the servo "simples"

8v + FBL will drain your lipo seriously quickly, and it will heat the servos up big time. I'd consider wether you will really benefit from running at 8v instead of 6v.

They are JR8717HV's that's why I'm asking

Thanks for all the help guys!! I get it now!

It's not the voltage thats the problem, it's the refresh rate on the servo. On a FBL system, I believe it updates the servo position 4 times more frequently than a normal flybarred, hence why they heat up.

true but im sure if your using HV servos its not a problem

this again is true but if you find the servo heating up you can reduce the frequency down and that sorts the problem out

Shaun,

I have read on the Beast forum (www.beastx.com) that the BeastX development team have been running one of their test machines with 8717HV’s on 2S (8.4V) for hundreds of flights without issues. So, I think you will be okay.

As you know, I am using Align 610’s on my new 700 ~ it seems there has been mixed success at 8V on these servos so I’m going to use a 6.6V LiFe on this model via an AR7100.

With respect to powering the unit, the Beast will take its power from the cyclic / pitch outputs of your Rx, so in your case 8.4V across all connections on the beast unit. You need to wire it up so the tail servo takes the signal output from the beast and the regulated +5.2V power from the ‘Rudd’ output of the 7100 (you can take the ground reference connection from either the beast or the Rx).

Cheers,

Lee.

Here you go………….

My tail servo won't work when connected like that! Any ideas guys??

[millerman]

and you have tried it like i said ?

[Lad]

Have you set the Beast up correctly with the appropriate settings for your tail servo..?
