Issue with version 115

[nzreg]

I updated my firmware to version 115 now my cyclic servos look as if they are breathing.
On the bench they move up and down by a small amount in a regular cycle.
It look for all the world as if they are breathing independently.
My reason for updating was a noisy tail servo and the collective would give a slight twitch about every 6 minutes.
I have rebound the system, I use the Spektrum satellites in DSM2 Mode.
With version 115 the tail is just as noisy but now I have this swash movement.
Can anyone help me with version 114 for download I would like to go back to this version.
Or perhaps tell me how to wind back to 114.

Many thanks

Are these large servo movements. If so, somethings not right. If the servos are just buzzing/creaping a bit with the machine on the bench it should be OK.

the servos on my trex 450 buzz and adjust on the bench and it flies great. same on my logo 500se with vbar and sk

Thanks for the replies. I did some more testing and found its only one of the cyclic servos moving, the movement is around 1mm but very consistent.
I left the heli sitting on the bench for forty minutes last evening and over that time the servo caused the swash to take on a pronounced lean to the left. I turned everything off then on and left it sitting for a further 15 minutes, this time the swash stayed put.
Beats me but leaves me wondering if this is going to get worse.
The tail servo still sounds like a washing machine.
Wonder if there is a fault with this servo.

i had the same issue with 115, i installed twind dsmx sats and the problem went away, so 115 is working well for me

Hi Reg,

having the heli powered on on the bench is not really a good test to tell anything. Reason is that we are talking about a control loop. This does not know '0', so simple speaking it is always at work. This means that within 40 minutes without any inputs by the radio, not being in flight and the heli is reacting properly to these inputs, this is something that surely happens, but not due to a faulty system.

Regarding the tail, this may be normal if it is a constant noise, but no real movements. Same reason: the control loop never sleeping

I receiced a personal email from Joachim resuring me that version 115 is fine. I have 5 HCSX units and so far upgraded 4. On wednesday we flew for 4 hours in bad windy conditions and the Helicommands worked very well. We only use Futaba S-Bus receivers. So Joachim, thanks to you and your team.

Thanks for the reassurance Joachim.
This morning I took the plunge and flew.
Perfect, this heli has never flown better, I have two of the M series Rigid HC and they are good but this one combined with the tail gyro is very stable and flies like a charm.
