Channels 'jittering'?

[sabre2]

Hi

Happily flying in Phoenix for a couple of months, today aircraft started 'jiggling' through the sky. When I look at the calibration, the channels themselves are 'jittering' slightly.

Any ideas what's causing this? I've tried a different USB port, just in case, but no improvement.

Cheers

I've had the same happen, no idea why.
Recalibrating seems to sort the issue.

What TX are you guys using?

I found ages ago there was a faulty batch of FF9 adapters floating about were the RS232 signal did not have a common negative between the TX and computer so it caused the signal to float slightly.

I'm using a DX7.
Just checked mine again and there's a bit of wobble on all channels, more on the left stick than the right.
I assume it's software related because with that amount of movement (about 2% I reckon) I'd have servo movement on my real helis.

Mine's a FF8. It's been fine until this weekend. I'll try re-calibrating from scratch.

Nope, re-done the calibration, tried a different TX, same thing.

Damn, back to Phoenix.

I'll come clean, since I raised this in a public forum. Following an exchange of e-mails with Phoenix today, I've found 'Turbulence' was set to 100% - everything else set to zero.

I should have guessed something like this, since it went wrong after a Small Boy played with it. Anyhow, the channels still jitter, but they must always have done, and I didn't notice - it doesn't seem to affect anything.

I'll think of some face-saving way of closing the call with Phoenix...
