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.
