Ghost I may be incorrect , but I was under the assumption that 2.4 Gz is the band width in wich the transmitter will work not so much the frequency itself , in that respect 72 mhz compared to 2.4 Gz is like comparing apples to oranges , there is no comparison 2.4 Gz gives you 100 times the available frequency options because it is continues to search for one that is a available and not being used at that moment in time within 2.4 Gz bandwidth ( in plain english ) you would have example ......100 available frequency with 72 mhz and 10,000 available with a 2.4 Gz
