I have a complete Aerofly Professional with control box and all tx cords, etc. had it one month, can't get it to work with my computer; only recourse is hours of long distance phone bills to Florida (Ikarus has no toll free number) or on line help-difficult with only one phone line/one computer. I am on limited income. Cost me $206.50 USD. If you want, $150 USD. I haven't asked them for return priviledges but they seem very willing to help me.
