Thank you, glad you find it useful.
Your transmitter usually needs a USB out port, or a 3.5mm trainer out port. I don't think that hubsan transmitter has either of those, you will have to check.
Some people are using USB RC trainer dummys such as this:

(Not sure if that will work on your computer though).
If you want to use a real transmitter that you can also use for actualy flying the Devo 7E is one of the cheapest alternatives:

(You should know that it doesn't have long range unless you mod it though. The Devo 10 is better in every way in my opinion, but cost twice as much).
The flysky fs-i6 is even cheaper. There are many other alternatives too, my suggestion will have to be to look around and see what suits you best. Also make sure that the one you choose will work on your setup. For some you will need an ordinary USB cable, for some a USB dongle, for others a standard 3.5 mono audio cable works best. For some a wireless receiver such as this is the best alternative.
If you want to spend a bit more money on the hobby, and are thinking a bit more long-term, a lot of people are recommending the Frsky Taranis.
