hi mate,

i beleive on 27 mhz there are less than 13 frequencies including splits .. ?

on 40 mhz there are over 25 maybe 30 frequencies..

you will have less chance of a clash on 40, but alot more people are on 40 mhz at race meetings so the 27 mhz would seem to be the best option, most of the top radio sets are on 40 mhz..
c
fm and am are the different types of wavelegnth lol if thats spelt right..

alot seem to be going for the spectrum conversions on there handsets which is a very good idea but can be very pricey, you probs already know about it but they come in wheel and trigger too ..

hope this has been of some kind of help to you mate ..
