I like the Tactic Tx and haven't used the wireless , but I have verified that it works on the bench. I actually sold a bunch of extra Tactic Tx because all my planes came with them. They should be readily available and very cheap. The thing I don't like about tactic TX is the lack of multiple memories. I fumbled around with 5 planes and 5 transmitters before I got my radio issues sorted out.
Tactic now has a nice anylink module that allows nearly any tx to be used with their rx. I'm going to get one. Unfortunately I don't have the option to build because of time and lack of knowledge and tools. I'd rather buy it and fly it.
