Good move on the tail servo BF.....Remember the SpringRC tail servo that burned out on me last year...

That is something that I missed as well. I know I have had mine running at 200

Yes, and my one using the GA250, as well. But going by what mhills51 found out, I think they would be alright, as long as they are used at 280Hz or less, which is why the one on this 450 Pro has worked fine (the GP780's digital mode works at 280Hz).

I just changed mine to 65Hz. My Favorite 450 I did have set to 65, but the one that has had a unexpected crash was set to 200. I still think the crash was a shorted out tail servo and not the Hz

Does anyone know what the ZYX and CX run the cyclic servos at when set to digital? I'm using DS410's on my 450 with a 3x1000 and they stay cool, not more than a few degrees above ambient - in stark contrast to the Goteck tail servo which hits about 60f above ambient.

It's in the first post of the ZYX thread. 111Hz if the tail servo is not 760us and 133Hz if it is.

Everywhere I have read the goteck isn't rated above 70Hz.

Thanks! I must admit I haven't checked the first post in a while - like many of your threads, it's grown into a monster!

Seems like another advantage for the Hobbymate and similar units over the ZYX family, unless it's a parameter that can be changed with a firmware update.

The most likely result of having the Hz too high is a burnt out FET driver or motor, but usually the servo would be getting hot, like when I ran the SpringRC tail servo at 333Hz.

The only other possibility, if the servo is running cool, is the motor brushes wearing out too quickly.

Not being able to set 280Hz in the ZYX is a disadvantage, but one that is starting to matter less, as we get more servos capable of 333Hz.

Regarding the cyclic at 111Hz, I'd be surprised if most analog servos got upset by this frame rate.

Don't Panic! It looks like it's a mistake on the BeastX site. It should say 165Hz, which is the Violet/Purple setting in the V1 and red flashing in the v3.

But both V1 and V3 the beastx still say 65 and not 165Hz In fact your only choices are 50, 65, 120, 200

Sorry, my bad. I was looking at the tail servo frequency.

Good to know. That was the most money I ever spent on a tail servo too..

Remember me ,the one who keeps complaining about how super unclear much of this FBL stuff is?

I have several different Servo / FBL operation sites bookmarked and guess what they often have greatly different specs.
Here is one

http://www.spartan-rc.com/resources/servodb/servo.php

DS410 listed at up to 333 Hz.
Some servos you can not get specs. even from the manufacture, most Vendors are fairly good at taking your order and funds but are not able to give useable tech support.

Sad thing is that even non electronics such as FBL heads of the same size (450) , sold under the same name ( Tarot) use some same parts (spindle) and some same bearing but not all and use different shims or spacers in the head or use non. One can not even find a assembly drawing most of the time.

No wonder many just purchase a Blade 450X.
