I am having problems with  my yoke and throttle , they just go crazy when i powerer up ,i used ALPHA  linear pots (b100k) ,they are connected to the MUx. they however work fine when connected directly to the Atmega. i added the pull-up resistor(10k) as suggested  but still the same problem. My cable length unfortunately is 90cm from pots to multiplexer. i have even added filter caps(0.1uf) to the pots but still. Any other  recommendations ?

2. Make sure you don't have "ground loops" ( http://simvim.com/tips_power.html)
3. Use the shielded cable...
