Don,
I tried to getting the RC Aerochopper to work on my pc. It is a 1.2 gig Celeron.
I had trouble using the remote. If I plug it into either com port using a gender changer (new pc's don't have a 25 pin com port). The entire pc goes nutz, or should I say the ps2 mouse goes nuts.

I had to change it over to a slower pc I have on my LAN. But even that has issues with control of the heli.
I am awaiting a interface cord for my fp-7uhf and going to switch to the FMS program.

What is your doing?
Ron
