G3 ... Controller Replacement (or DX7 compatibility?)

[StealthGod]

So, I got a copy of Real Flight G3 from a friend who didn't want it anymore. The only problem is, he lost the InterLink controller. So, I have free software that is kinda useless right now.

Are there any replacement controllers that I can buy that don't cost too much?
If at all possible I would like to be able to use my Spektrum DX7. If someone knows how to do that I would be grateful.

Thanks.

Unfortunately the replacement controller will cost almost as much as buying the software and contoller new. This is thier way of copywright protection. You need the Interlink controller to use the software.

Thanks for clearing that up. I guess this software really is useless now. Oh well.
