My questions:
1. How do I take advantage of model memory so that I have a single tx that I can use on multple cars?
2. Do I need to purchase the same rx part for each radio?
3. Or, can I purchase a compatible rx for the tx - compatible meaning any rx of the same tx brand?
4. Or do you guys simply install the rx for each additional vehicle you want to use the radio on?

Example:
Let's say I purchase the Spectrum DX3C for my D8T. It comes with the sr300 rx. Can I use the radio on my Losi 810 (which also has a sr300 rx)? If so, do I just bind the two? Assuming this is true, when I build my Mugen MBX6, do need to get an sr300 rx, or will any Spectrum receiver work?

Finally, what are your thoughts on telemetry? Is it worth it...is it accurate....is there a large footprint with the additional wiring?

Thanks!
