Requesting ideas and considerations for newbie to R/C with microcontrollers

I am wanting to use a cheap R/C transmitter & receiver system with the Propeller on a rover project. Does anyone have an opinion on this low-cost package?

For $30, it is hard to beat for a newbie who may wind up damaging it somehow. I value the experience here and just wanted to see what the overall feeling is about this particular system. I will be interested in any other low-cost systems that may be reommended. Thank you.

    I second this. I'd love to get an R/C transmitter/receiver that doesn't cost an arm and a leg. Just for toying around with.

    That's the one that I've used in my robotics classes, in conjunction with a Propeller, and also with a model sailboat that I built. It works just fine for both apps. That said, however, it's not as resistant to interference from other transmitters as more expensive units are when there are a lot of them being used simultaneously, as in a race. But you have to pay more for a nice Spektrum system that overcomes this issue.

    The only other downside I can report is that the transmitter takes eight AA batteries, and that the battery cover latch doesn't hold all that well. But for a unit that retails for only $30, those are pretty niggling complaints.

    Thanks for the feedback! It sounds like a good setup to start out with. Much appreciated!

    Should work just fine. There are lots of objects for reading receivers in Spin, PASM, or C/C++. Also, that unit would very likely work with rechargeable AA's. :)

    You can swap out AA's with a Lipo. A 6 channel transmitter for $30 is a great price.

    Again, some very good comments... JasonDorie, I actually had not even thought about the OBEX... glad you reminded me! Lardom, LiPo will indeed allow for more time in the field. Thanks all!
