In this photo, see how some of the car crystals are red and some are black? This tells if its a 6 channel set or a 12 channel set...
6/12
US/JP
RED/BLACK
X = 01
1 = 02
X = 03
2 = 04
X = 05
3 = 06
X = 07
4 = 08
X = 09
5 = 10
X = 11
6 = 12
Examples:
Channel
4 and channel
08 are the same frequency, thus conflict with each other.
Channel
4 and
04 are not the same frequency and will not conflict.
