Spirit System

Hello all,

as i did not find real clear information about it in other sources: all full size 760µs Futaba BLS tail servos (like BLS251, BLS256HV) in the Spirit servo list are listed with 560Hz frequency with exception of the newest & best BLS276SV... 333Hz only. is this a bug in the list or true? seems strange to me it is spec'd down vs. the predecessor....

i've just upgraded one heli with BLS276 to Spirit RS and the next 1-2 in preparation... want to be sure about it. the one with good old BLS251 is running 560Hz since ever. another question is if we could feel the difference between 333/560Hz on tail... ?

HI HeliMLM
I run the Futaba BLS276SV in 560Hz whith Spirit RS.It is the best tailservo i ever own.
It is four years old now and it has many flights in my G570,still performs 100%.
I by mine new and the manual says 760us and 560Hz.
In my Kraken i have a MKS HBL980 and i have problems whith jitter and randomly yerks,only at
High rpm:s(2100).Try moving the antennas around in different directions but nothing seems to help.
So i just dont fly at 2100rpm.
Fly high

Hi Latjo,

thx for your infos... and yes: for me too it is the top tail servo... all of my helis >= 550 are equipped with BLS276. my Logo 600SX has been converted to Spirit RS recently and i set it to 560Hz too... performance is flawless - but in preparation of the next helis to be converted to Spirit i've seen the 333Hz in the manual and was a little afraid of burning the servo
