Yes, they are very small. I am using them on both my Revo and Jato if you want to look at the pics to get an idea about how small. And, I think Spektrum even has a mini version.
Yep, I have that very same RPM box and the standard Spektrum receiver fits in there like they were made for each other. :003: The bonus is that the antenna is so short you don't have to run a mast. I do love how the box bolts nicely into the servo spot too.
The length of the wire is determined by the frequency of the radio transmission. Higher frequency=shorter antenna. Since Spektrum uses 2.4GHz, the antenna can be quite short. As a matter of fact, Spektrum says you can cut the antenna (to a precise value) without appreciable loss. In my Revo, I have the antenna base mounted to one of the stock brake "caliper" holes and the mast doesn't even exceed the top of the stock rollbar. Range is about as far as I can effectively drive it (500-600 ft at a guess).
None at all. In fact the range is much better than my FM setup ever was. I posted this in another thread, but here's a pic of the receiver in the RPM box.

I'll have to check those out. Should I look at purchasing an entire system, or does that reciever work well with the stocker transmitters.

AFAIK, The only way it will work with non-Spektrum transmitter is if the transmitter has a module plug-in port so you can plug in the Spektrum module.
I love the Spektrum, but there are two things I wish it had: speed sensitive steering (where steering moves less the faster you go) and more model memories. My DX3 only has 3. The newer version has 4, so that's a bit better. The receivers are VERY small so they fit pretty much anywhere. There's even a Pro version which is even smaller. All in all, it's a nice radio with some nice features. I've never had any kind of interference or glitching issues at all.
Some people may suggest getting one of the Nomadio radio systems instead. IIRC, Squee was a proponent of that system so he may offer more advice.
