@rocketman221projects - I'd say 100 feet is about the limit, and that's pretty much what the FCC allows as well.

If you got to Picasa and search for "Zinc Negative Resistance Oscillator" the schematic should come up.
The ZNRO is a neat science project, but can be tricky to adjust and may not be stable for long periods.
For those who want a "real" AM transmitter for home broadcasting, etc., there are plenty of plans on the internet and kits are available from various manufacturers. Have fun!

Thanks for the question, but this technology is not stable or suitable for RC purposes. You'll want to use a system designed for radio controlled cars - google will show many sources.

@bigred109 - That's ""Wild Weekend" by the Rockin' Rebels. It was originally the theme song for the Tom Shannon radio show on WKBW Buffalo, so it's got a bit of a radio heritage too! You can find the whole song on Youtube.
