2.4G FS-CT6B 6 CH Radio Model RC Transmitter & Receiver PPM/GFSK Heli/Airplane/Glid 12V DC

This isn't your top-of-the-line Spektrum transmitter, but for $40 I'm definitely not complaining. I am personally using this as the fail-safe for my home built arduino-based quadcopter, and so far it hasn't given me any trouble. I never used the included CD because there are a lot of good resources online about how to install the drivers and get the receiver up and running. (search T6config)One thing that isn't mentioned in the product listing that should be is that it takes either 8 AA batteries (which it eats up in about 20 minutes of flying) or a 12V power supply. I quickly opted for the 12V external power and fly from a car battery or a DC power supply plugged into an extension cord. I figure I can go for a LiPo pack later but for right now, I really like that I don't have to buy 8 AA's every time I go flying. The plastic feels a little cheap and it feels a little ridiculous without any weight from the batteries, but it does it's job. Like I said, I'm using this as a fail-safe just in case my arduino-copter goes out of control I can bring it back. Most flights I don't really touch it, but it certainly has saved me a few times.Exceed RC has a great interface program which allows you to save and load different profiles to the transmitter. I honestly haven't used that functionality yet, because I only use this for my one quad, but it looks like it might be useful for the more serious RC guys out there. I bet they also are paying more than $40 for a transmitter so I'm not sure how useful it is in the end.Perhaps one thing I should note: my transmitter came without knobs on the joysticks! It wasn't a problem because I could go and machine some knobs out of some scrap aluminum to stick on, but it was certainly strange to have the bare shafts right out of the package.

The transmitter works great, but I need to reverse 2 servos and the only way is via the software that does not work on my laptop. Overall performance and sensitivity is great especially for the price.

Works great and I love the low price! I can now have total set ups for each aircraft! More flying time and less confusion!!

this radio came nicely packaged in molded foam like most electronics.Pros:1 - It works.2 - it plugs into your computer allowing you to change endpoints, reverse servos, set mixes etc with included software on mini dvd.3 - Unlimited model memory stored on your computer, as many different setups as you like, loaded with the click of your mouse,4 - 6 channels, 4 on the sticks, 2 more controlled by your choice of a variable dial, or a off on toggle switch. ( both 2 position switches)5 - Has adjustable dual rates.6 - Its lightweight, this might be a con, but im gonna list it as a pro because its easy to hold it for a long time.Cons:1 - No instructions. zip,nadda,nothing. Had to go on utube for a instructional video to figure out what several menu options did.2 - It plugs into your computer for programing, meaning if you don't have a computer with you, you will not be able to make adjustments to endpoints, reverse servos, mixes, or anything else. It does have trims on the outside case for the 4 stick controlled channels, but they have the least amount of adjustment I have ever seen in 30+ years of using rc toys.3 - Even after setting the endpoints to max, for some reason, this setup does not throw ( move the servos ) as much as the radio this replaced did. Kinda very disappointed with that aspect of this set. I also had to reposition the horns on the servos, to compensate for all of the channels being what I call "off center", and the minimal amount of adjustment the manual trims on the radio provide.4 - had a difficult time binding it, took 4 attempts, didn't do anything different each attempt, so that was kinda weird. note on binding here, the receiver will flash red when unbound, and solid red when bound. do not forget to remove the binding key before actual use.5 - hard to describe this con accurately, I don't feel that I have fine control over my vehicle, it starts stops and turns when I tell it to, but it is not in anyway smooth. sorta like it jumps from 0% to 10% with no in between when you move the sticks, but after that, it seems smooth the rest of the way up from 11% to 100% movement. ( percentages used are estimated to try to describe the issue )6 - Some operating systems require you to download a driver in order for it to recognize the transmitter is plugged in. I found the link on utube in the instructional video.Wile this is marketed as air radio for planes and helicopters. I bought it for my rock crawler. I wanted separate independent control over both front and back steering servos. Since this is a 2gig radio, there is no harm or foul in using it for surface like there would be if it was a old crystal channel based FM or am system, fcc and all that.I am currently using the sticks for throttle, and independent front and back steering, have set one switch to toggle the dual rate on the throttle to 20% on and 100% off , this works very well when navigating a tricky obstacle. I have also used the mixing function to make the other switch control both front and back steering with 1 stick, when turned on, So it is indeed doing what I bought it for, just not quite as good as I had hoped.I decided to buy this low end inexpensive radio mostly because of the environment I crawl in. Mud, dirt, sand, Snow, rain, or shine we play. So I didn't really want to risk a more expensive transmitter, If the elements eventually destroy the transmitter, ill be allot less pissed then if I had spent 150 or more. There were no reviews when I bought it, but I took a shot anyway, im for the most part happy with it, and as long as you understand the few drawbacks before purchase, you should be too.

No documentation is true. Hard to find an adapter that will allow you to recharge batteries. Does work with Arduino if you are planning of using it for a robot. But you need to test out the channels to see what their maximum and minimum values are. I could not get the speed control Left vertical stick channel to show anything, but then I did not need it for my application. I suspect that it needs to be programmed using the CD program to configure your channels. I did not need to pair up the transmtter and receiver because their appear to be pre-paired.

Great controller. With 6 channels it's all you need. Best bang for your buck.

Would be a nice Transmitter if it came with a disk not a web site. And it would help to have a receiver to mach the two to make it work. My opinion is that it is a out dated Transmitter I am new to this but not dumm.

For the price I paid I really can't complain much. This is being used as a test unit for my robot lawn mower and will be used for future builds as well. So in my case... It's kind of considered a "disposable unit". Once it does malfunction too bad, I'll toss it and but another one. I received this today and have already used it. Since I only have 2 servos and 2 motors to control it functions just fine. I gave this a 2 star rating for these reasons.PROS: Affordable for experimental purposes such as my robot and it does what I need it to do with minimal programming.CONS: It does seem to be a low end controller and it shows, it's extremely lightweight and feels cheaply made. The battery cover does not stay on well at all, in fact through normal movement it fell off 6 times in an hour. There's no literature included with this product. It is available online in many areas (I used YouTube).
