Note: The difference between the X18S and the X18S SE are a higher quality screen with improved visibility in direct sunlight and the custom red paint job.
The Tandem X18 S is very similar to the X18. There are three upgrades that the X18 S has that the X18 does not; and are as follows.
- Flash Storage has been increased from 128Mb to 512Mb
- A built in 6 axis gyro
- MC18 CNC high-precision, hall sensor gimbals, sporting 10 ball-bearings and adjustable stick travel from 45° - 60°
The FrSky Tandem X18 S is a dual-band telemetry radio that features a color touch screen display, ergonomic design, Tandem dual-band RF system (2.4 & 900), and most importantly Ethos - Frsky’s newest operating system. It boasts an impressive end-to-end latency, ergonomic design featuring low weight and a thin profile, natural switch, button, and slider positioning, hall effect gimbals as well as built in mass storage.
The biggest innovation in this radio lies in its software, Ethos, which has been designed from the ground up to encapsulate the power and flexibility of OpenTX while retaining the ease of use and user interface of a menu-driven system. It features customizable elements such as sounds, model images, and splash screens, while also including an easy to use setup wizard, tips while programming, along with preset and complex mixing options and flight modes.
Ethos makes quick work of programming simple planes or something complex like a full-house glider. If you are familiar with OpenTX, Ethos will feel really familiar but faster and easier to use. If you are coming from a menu-driven system, Ethos is a supremely powerful and easy to learn software that will have you up and running in no time. We like to say that Ethos can do whatever you can think of for a radio to do! Yeah, it can do that.
The X18 S also boasts some features new to FrSky radios. A crisp and responsive 480 x 320 touch screen that is easily visible in sunlight, backed by a more powerful CPU. If you prefer button navigation, full functionality is still available through the normal nav buttons, so no need to touch the screen.
USB-C charging (2A+), an included 4000mah LiPo battery pack, and FrSky’s robust telemetry system with a huge selection of receivers to meet any need.
For those that may be new to FrSky, you will be getting the most robust telemetry system ever built into a hobby level radio. From simple voltage and signal strength monitoring that has helped avoid countless accidents to advanced features like monitoring amp loads for an individual servo, fuel flow sensors, air speed, and so much more, you will not find a better telemetry system in the hobby.
Here are a few more highlights:
6 Quick-Mode Custom Buttons on lower front
2 Momentary finger tip Buttons on the rear
External Module Bay for other RF options, etc (Lite Type)
Haptic Vibration Alerts and Voice Speech Outputs
High-speed PARA Wireless Training System
High-Precision, 10 Ball Bearing, Hall-Sensor Gimbals with adjustable Stick Travel 45°/ 60°
M4 Gimbal stick ends Sbus, S-Port and F-Port
Integral flash memory storage with SD card slot
Easy-to-reach top switches and sliders
Included in the package:
Soft Sided EVA Travel Case
Lithium Battery Pack
X18 S Tandem Transmitter & Neck Strap
Here's a link to the professionally written Ethos manual page.
To get to the manual follow the link, then click on one of the release links on the right. Most folks will want to click on the one labeled "latest." From there you will click on assets, and then the manual is in the item labeled "source code."
A bit of a learning curve, but videos of how to’s quickly bring you up to speed. Ethos OS makes programming much easier. Downloading templates of existing aircraft settings can get you flying in a short period of time. Good tutorial videos are available online, faster than reading a manual. Beautiful red color on X18SE.
I was frustrated with open tx so I went to Spektrum. After a few years of enjoying the ease of use with the IX12 I found myself knee deep in planes. I couldn't keep spending $85-$115 per receiver for only 6 channels. Then I had issues with two planes having brown outs. I decided it was time. This TX has been absolutely amazing. A very easy transition and I'm ready to order another for the kids. Will buy more and Aloft is amazing!!!
Great so far. My first FrSky tx and also first Ethos. Feels good, menu easy to follow, Mike Shellim templates available online for f5j so what's not to love.
Tandem X18S - Awesome Transmitter
Recently purchased the X18S and was anticipating a somewhat decent transmitter but when I opened the box, I was pleasantly surprised to find a high quality unit. The Ethos operating system will take a little getting used to but the touchscreen makes navigation a whole lot easier. I’ve yet to register and link a receiver to it, I’ve got a couple stashed away, but I plan on using this transmitter on my next project, after I have a chance to familiarize myself with the features.
