Help with Tx... Whats a slider?

[kiwi320]

Hey guys, looking at new transmitters for my Trex 450 (and 600e that's in the build) and I'm wondering about these 'sliders' that people talk about.

I've looked at pictures, but can't see anything that slides on a Tx apart from the trims.

Reason I ask, is for Gyro or FSU control (I plan on putting a AP2000i in my 600 for AP).

But, how do these sliders work.. What do they look like.. What's a reasonably priced Tx with a slider (or two)?

And can anyone post pics of theirs and what they use it to control?

The 9c, 9303 off the top of my head have levers on the side of the transmitter, about where your pinky finger would be. They can be assigned to proportional channels, work great for things like flaps on a plane. They function like a knob but you dont have to take your finger off the stick to use them.

The dx7 and most of the low end radios dont have them.
