(*)(**) Set the transmitter's modulation as "PPM" to use the TM-7, TM-8.
(**) The position of the TM-8's mode selection switch, either 7 or 8 channel, will determine which receivers may be utilized. Please note, when using the R6014FS receiver with the TM-8 in the 8 channel mode there are only 8 channels available for use. The TM-8 may be utilized in the 8 channel mode with a T7U transmitter, however, you are limited to only 7 channels as this is the maximum number of channels transmitted by the T7U transmitter.
