    "Choose the TTX850 radio system for computer sophistication, performance and programming ease. Its software has features for virtually any aircraft, from airplanes and helis to multi-rotors. Adding that to its wealth of functions and generous memory, the TTX850 could easily be the only radio you need to fly an entire hangar full of aircraft."

    This is a quote taken directly from the TTX850's webpage. Tactic must really think they're on to something with this new transmitter!



    They've got a lengthy list of features as well - between the quad-bearing gimbals and high-resolution backlit LCD display, it appears that this new transmitter has something for everyone. But wait, Tactic is also telling us that the TTX850 is affordable AND includes all these features? This I have to see!

    So, without wasting any more time, let's get the box open and see what we've got.


    • 30 Model Memory
    • Airplane, Helicopter and Multi-Rotor Programming
    • Wireless and Wired Trainer Systems
    • User-selectable switch assignments
    • High-Precision Quad Ball Bearing Gimbals
    • Internal Antenna
    • AC Wall Charger with Interchangeable U.S., UK & EU terminals


    • None as Tested

    The TTX850 arrived in a full-color cardboard box with something refreshing inside - recyclable packing material. The fiberboard tray does an excellent job of protecting our environment as well as the transmitter!






    I really like the transmitter's face. Its layout is simple and gives access to all of the chromed switches during use. There's a large LCD display and six buttons to navigate through the TTX850's menu screens - I'll show you more of the screen in the videos. A Tactic branded adjustable neck strap is included for us pilots that fly with a strap.






    There are four assignable switches on each shoulder of the transmitter. I really like that they are all assignable, giving me the option to put control where I want it! There is no external antenna to accidently break - the single antenna is tucked securely inside the transmitter's carrying handle. It was a little odd, at first, to see a transmitter without an external antenna, but without the fear of it getting easily broken, I think I can get used to it.






    Tactic has included a universal AC charger. There are three adapters included (US, EU, and UK) to allow charging in several different countries without purchasing a different charger! Simply choose the plug-in you want, and slide it onto the charger. A small tab on the charger locks it securely in place.



    I almost forgot! There are also two assignable sliding switches on the back of the TTX850's case as well - I do like this type of switch for flaps.



    Manual


    The included instruction manual is up to Tactic and Hobbico's usual standards. It's easy to read and the illustrations are done very well. A lot of information is included, so you may want to read it AND keep it handy when using the TTX850.






    A Minor, Personal Adjustment





    Aside from charging the battery and installing the receiver, there was no preparation required. With that said, I did change the stick tension. I like my stick tension pretty stiff, and this was done easily by removing the six screws in the back of the transmitter. With the screws removed, the transmitter case split easily, but proceed with caution - there are wires connected between the two case halves. Adjusting the stick tension was easily accomplished by turning the tension screws. I then reassembled the transmitter, and it was ready to guide my aircraft though the sky!


    Tactic TTX850 Introduction


    Tactic TTX850 Basic Programming Walk-Though





    I really liked the TTX850. Though full-sized, it feels lightweight in-hand. This is not necessarily a bad thing, and it's good for pilots that don't use a neck strap when flying.

    After installing the TR825 receiver in the WIngsmaker Handyman Twins, I range tested my plane and all proved to be working well, so the plane took to the sky. I put the plane through several aerobatic maneuvers, and the Handyman Twins followed my every stick movement. The TTX850 did a great job the entire time!

    Moving indoors, I linked the TTX850 to my Heli-max 200FP. The linking process was very quick and simple, and the helicopter functions were easy to use. Granted, setup was really easy due to the 200FP's fixed-pitch design. In the air, the small helicopter felt very stable and hovered nicely with a bit of trimming. To be honest, I preferred the TTX850 to the small transmitter that came with the 200FP.



    Tactic TTX850 Flight Report




    Sometimes, I find it hard to write a transmitter review summary. In the words of my late friend Mike Buzzeo, "there's only so many ways to say that a transmitter worked". But I will say it again - this transmitter worked, and it worked extremely well! I liked the features in the transmitter - it's a great radio system, and to be able to get an eight channel computer radio for less than $180.00 is a really good deal! Try one of these TTX850 transmitters out for yourself, and you'll like it as much as I do! Another great product from Tactic and Hobbico - I can't wait to see what's next! Possibly a 10 or 12 channel radio system? What do you say, Tactic?

    So they got rid of the hinged antenna that breaks if you just look at it wrong? Great!

    I don´t know how tu turn off a "SEARCH SIGNAL" that came on top of the screen of my TACTIC TTX 850. And enables the transmiter.
