i need help with Quantum wireless flash.

I have 2 T5D-R flash system now.

I want to use it wirelessly. I'll attach one T5D-R to the body and the other one will trigger wirelessly.

So, i'll have to buy FW7Q FreeXwire and attach it to the T5D-R right?

Do i have to buy FW89 FreeXwire Wireless TTL Kit? How is it going to work?

If you get the FW7Q for the remote Qflash, all you'll need is a Tx unit on the camera end to trigger the FW7Q. The Tx unit can be the FW9T or the FW10w units. Or, if you get the FW89 Rx/Tx kit, you can forego the FW7Q and use the FW8R with the remote Qflash.

If you need to retain ETTL compatibility, then you'll also need the D23wR module.

So if i'm going to buy FW89 Rx/Tx kit, i'll attach the FW8R Receiver to my remote qflash so it can receives the signal right? and the FW9T transmitter at the camera to send out the signal?

also, my ST-E2 will become useless? i'll not need it anymore? or can i use ST-E2 to control both Qflash remotely? is it possible?

If you want to use the ST-E2 to slave the Qflash, you can get the Qnexus module. This module will essentially turn the Qflash into an EX compatible flash except for some unsupported functions such as HSS.

thanks for the info. Just order all of it from BH.
