Hi all,

I have the same problem with the controls jumping all over the place and can not calibrate.
I use the USB version and a Futaba 9C Tx on my BenQ Laptop with 1500Mhz CeleronM CPU and Radeon 9600 built into the motherboard.
My AFPro version works without a problem.

For AFPD, I have the new cable, downloaded the latest drivers I could find, Uninstall AFPD, defrag, reinstall. I get good frame rates of 100 to 200 FPS depending on field and aircraft, smoke etc..

ANYHOW, I was getting totally frustrated by not being able to calibrate or fly.
I noticed that the when I put my Tx down the red bars stopped flicking, when I touched the sticks the bars were OK BUT when I touched the metal body part of the Tx the bars jumped all over.

For the moment my solution has been to make a wire with 2 alligator clips. 1 clip on the Tx Antenna and the other grounding on metal on my Laptop.

The bars are steady, I can calibrate and fly. I hope it stays this way as AFPD is worth the effort to attach the extra wire when I hook up my Tx.

You should try this "grounding" experiment and see if it works for you.
