As long as the crystal is compatible with the radio and it should be fine... I've used Eagle/Integy Xtals on my Futaba Radio awhile ago...they worked great and didn't glitch.

The FCC will get ya if you are using the wrong freks. They do drive bys and check RC tracks, at least that is what they say. Not worth the risk of a fine and possibly shutting down your favorite local track.

Default Scanning Frequencies

Guys;

I have been to an R/C Air Field that used a custom made scanner to monitor who was on what. So it's not impossible to do.

BUT, I doubt the FCC has the time, money and resources to monitor all of the R/C tracks in the USA.

nobody is doubting that it is possible. Frequency scanning is actually fairly elementary. But can you imagine the FCC actually employing thousands of teams of undercover agents, driving around cities parked out front of RC races monitoring what frequencies the kinds are using!? buhaha! that would cost millions and millions of dollars...

for it's size it's very accurate.

Post US ROAR Approved Frequencies

RADIO EQUIPMENT
1-51: Radios used in ROAR competition are limited to the following channels: 27 MHz–Channels
specifically, 26.995, 27.045, 27.095, 27.145, 27.195, 27.255.; 75 MHz–Channels 61 through 90, to
include odd and even numbered channels; 50 MHz–Channels 00, 02, 06, and 08; and 53 MHz–
Channels 100 through 800. Radio Shack Frequency Counter (Part # 22-305) or similar device is
recommended for testing for legal frequencies.
1-52: All radio equipment must conform to FCC rules. Only narrow band (20 MHz spacing) radios
will be allowed to use the 75 MHz frequencies in ROAR competition.
1-53: A driver must use his assigned frequency. All frequency changes must be approved by the
Race Director. The use of reversed crystals is prohibited.
1-54: Drivers using 50 MHz and 53 MHz radios must have an FCC Amateur Radio license issued
for that radio in their possession. The use of radios operating on 29 MHz, 40 MHz, or CB (split)
channels is prohibited.
1-55: Radios will display the clip for the frequency used during practice. Radios must be able to
change frequencies. At Level 3 and 4 events, two alternate frequencies are required.

Later,
