mouthpiec,

With Futaba receivers, the last number is usually the number of channels, such as your R147F is a seven channel receiver, a R124DF is a 4 channel receiver and so on. I'm not sure what the first numbers mean, as they may just be model numbers, or series numbers.
Also, Futaba receivers come in low band and high band. Channels 16 through 35 are low band and 36 through 60 is high band. Just remember to buy the receiver that's in the same frequency band, (high or low), as the frequency of your transmitter. In other words, if your transmitter is on channel 24, you have to use a low band Futaba receiver. You can't use a high band receiver with the channel 24 crystal, as the high band receivers are tuned for channels 36 - 60. You can also use other brands of receivers with your Futaba transmitter, as long as they are negative shift. Hitec receivers work fine with Futaba gear, but JR's do not, as they are positive shift.
Of course, none of this might matter if you use totally different frequencies in Malta! What frequency do you use? Everything I mentioned above concerning frequency bands is for 72Mhz as used in the USA.
