The only thing cheap about this radio is the price.

Abridged Article Review

With Flyzone rapidly expanding their Tx-R fleet, and Heli-Max also expanding theirs, it was only a matter of time before Tactic released a transmitter that could handle more than a single model. For those who haven’t been introduced to Tx-R technology, it refers to the built in receivers used in these models. These receivers use the SLT protocol, which is compatible with the Tactic range of transmitters, as well as the AnyLink plug in module.

The AnyLink module has a somewhat limited range, but allowed you to use your own transmitter. Up until recently, Tactic had just a four channel basic transmitter, which required setting up each time you switched to a different model. With the TTX650, they have brought to the table a new entry level six channel computer transmitter at a very competitive price. Combined with the inexpensive TR624 6 channel SLT receiver, you have a reliable system that you can use in most applications.

What I wasn’t expecting was the incredible programmability of the feature rich Tactic TTX650. For this price point, Tactic gives you features that you don’t normally see on an entry level computer transmitter, such as a wireless trainer, unrestricted channel and switch assignment, user updatable firmware, quad bearing gimbals, plus it gives you the ability to store up to twenty models.

The transmitter doesn’t just look good on paper either; it feels good in your hands. I fly “pinch” style, where I hold the sticks between my thumb and finger, so I automatically lengthen the sticks a little with each transmitter I buy. The red aluminum sticks feel good, and the quad bearings give the gimbals a silky smooth feel.

Other physical features worth mentioning are the firmware and charge jack ports. The firmware can be updated by the user, but requires an optional cable to do it. The charge jack is only to be used if you upgrade your transmitter to a NiMH battery pack, instead of using the included “AA” alkaline batteries. The wireless trainer feature allows you to connect a student’s transmitter (any other Tactic transmitter), without the use of any cables. The trainer feature has a range of 15 feet, and makes handling the model a little less precarious with the trainer cord removed.

I have to say that I am impressed with Tactic’s first computer transmitter. It’s strengths are its programming flexibility, switch and channel assignments, set mixes for each model type and four additional program mixes, its large graphing display, 20 model storage, and of course the SLT compatibility. The menus are all laid out intuitively, and for the most part I didn’t have to look at the instruction manual when learning how to program it. If I had to pick out any faults, it would be the lack of a backlit display, and I would love to see some sort of slider or rotary dial. That being said, you are getting a lot of bang for your buck with the TTX650 transmitter, priced at $149.97 it is jam packed with programming and features that you just can’t find elsewhere in a six channel unit.

Video Highlights


I assume this is the new app that was promised. The resolution on the loop tutorial is much easier to read. And,the videos are quite a pluses.

Hi Tom-

Been using this with 2 planes for a couple months now. Really happy with it! It's a little hard to program, but nothing you can't figure out. Programmed Flaperons last night on my Sensi. Works great for landing in my front yard, slows it way down. Was a little hard to figure out what the book was saying on programming it. I finally just chucked the book and started pushing buttons till I got it doing what I wanted! LOVE IT!

For the price, can't beat it!!!!!

I have used this transmitter on seven different airplanes. From trainers to 3D, this radio handles it all! Can't beat the price either!

I am not really into electronic items and machineries. Tactic TTX 650 seemed to be a very advanced radio transmitter which has got a number of technically promising features. The properties of the transmitter were really amazing and thanks for sharing its features.
