My first two planes were RTF's that came with Tactic radios. I've been using Tactics now for over 3 years, with my wife gifting me the TTX-660 Tx for Father's Day a couple of years ago. I've had no issues with the Tactics, and for a reasonably priced radio system (6 channel Rx is $25 -$30 USD), I've been pretty happy with them. Battery life on the TTX-660 is respectable, on 4 'AAA' batteries, and the display shows the current voltage level of the Tx batteries (it's nice to notice when it's getting towards the low side, and change them before it alerts of low voltage in the middle of a flight). The TTX-660 has multiple model memory, and one of the features is a programmable timer that can be tied to any one of the channel controls. I set the timer for a reasonable flight time, with enough "buffer" left on the flight battery for one or two go-arounds (or to linger a little if someone else is on the runway).
That said, looking at various vendor websites, it looks like Horizon is slowly phasing out the Tactic line. The assortment of both transmitters and receivers has shrunk, and it appears no RTF planes come equipped with Tactic radios any longer. I'm seriously considering picking up a Spektrum NX-8 a little later this year, to both open up my options on BNF planes, and against a possible complete discontinuation of the Tactic line.
