I ended up using a HiTec flash 5 transmitter with this one instead of the game commander. Couldn't get it to work with the program and had this transmitter laying around. Works fine now.

Biggest problem is in about 4 weeks my laptop will be back home and I don't think ( daughter has been using computer at summer school) that I have a serial port on it. From what I've read serial is about all that will work. Need to search further about other possibilities.
