Hi.
Yes, surfaces ae jittering slightly.
Which radio are you using?
Futaba 9 CAP
Did you set your radio to PPM mode?
Yes

What type of adapter cable are you using?
The one provided

Did you push all the connectors completely in?
Yes

Did you perform a calibration of your radio in AFPD? If you're using high rates, you will need to calibrate with your radio set to high rates.
Yes
I use this setup for 3 years with no problem. When I installed the CD only in another PC it works fine!.
Perhaps is the sequense od upgrades or my PC that causes the jittering.
Can you give me the sequence of the upgrades installation?
Thanks for you valuable help
