No, that won't work with the Tactic, however, Tactic has a built-in wireless buddy box, so for about $160, you can get 2 tactic 4-channel radios and use the wireless buddy box.

Also, Tactic just came out with a 6-channel radio for $99

I used the wireless buddy box with two of the 4-channel models in this video:
