Hi, look here: http://www.rc-discount.de/store/prod...roducts_id=643
I ordered one, they are specialy made for DX6i...
I did not have time to configure my DX6i to make it work with helis, but it just came to basically work for airplanes.
Just get the file "emu.exe" so G3 or G4 will recognize it like a G2 device, and you will have only to create a model in your DX6i.
I just got my DX6i few days ago, still in the owners manual to learn the basics...
Here is a way to help you and me [8D] to set this device: http://ironcreek.net/dx6i/

Good luck
