The Turnigy 9X is one of the best RC transmitters out there at the moment for it’s price. For $60, you’ll get a 9 channel transmitter (8 usable), a receiver and a bind plug, but with no battery. I have been using this transmitter for over 3 months now, so I decided to share some of my opinions about this product. If you are not familiar with RC system or never own a RC transmitter before, you might find it a little difficult to use, because there is no user manual! However you will find it very helpful there are tons of Youtube Videos and instructions online.
Good things about the Turnigy 9X
I bought this RC transmitter primarily for my multicopters. Although we only need 4 channels to control a copter, it’s beneficial to have more spare channels in case we upgrad our hardware to allow GPS etc functionality in our system.
It looks nice, sticks have a nice smooth feel. There is no ratcheting feel to the throttle. The range is increditible with the original transmitter module and receivers. I tested 500m (around 1500 feet) and it’s still working great. I can’t go further because that’s how big the park is. I love the “profile” options, which allows you to program and save different settings in a profile. I believe you can have 9 profiles max. This is particularly useful if you have multiple planes so you don’t have to change any of your settings when switching in between.
The setup needs a bit of patience but once somebody gets to know how to use the menu it is a piece of cake. Even there are a lot of videos on youtube explaining how to program it. I have not had any problems or glitch from this product so far.
The Tunigy 9X I have is a version 2, there is now an in-built 2.4GHz antenna and the new system looks little different to the older version. The 2.4GHz side of things is vastly improved over the original system (pending flight tests to confirm that). It’s now a frequency hopper at an incredibly low price.
Emh, the down side
The transmitter module can be replaced but the antenna is actually hardwired to the module so you can’t actually “just” remove it or replace it with another. For some reason, they’ve soldered the antenna cable directly to the module’s circuit-board, rather than using a removable connector. This means that to fit another 2.4GHz module (e.g. Frsky), users are going to have to unsolder it.
A negative is the awful 8-cell AA battery holder that comes with the radio. it’s a very tight fit and getting the cover back on can result in the tags breaking off, worse though is that the battery holder is is far too tight in there, this prevents the batteries from sliding along to maintain contact (pushed by the spring) if the case is flexed, even by a tiny degree the batteries will lose contact resulting in your radio going dead. You can fix this by getting a purpose-built low discharge LIPO battery pack to ensure reliable operation and easier battery fit.
Second is the very annoying and loud BEEP!!! You get a loud beep every time you press on the buttons very annoying as it’s waken up my house mates a few times when they are sleeping. To fix that I cut the leg that goes from a transistor to the speaker and added a 220 Ohm resistor in between.
Third, the screen is a bit hard to see, you can buy a replacement screen with back light from hobbyking for this transmitter to fix this.
In summary, it’s exceptionally good value for $60, I would recommend it!
