do i really need a 2.4ghz for the mmm combo

[hk3948]

hey guys. i should be getting my 2200kv combo through in the next week and a half or so to go in my e revo. the problem is, i am so low on money at the mo.
what will happen if i just stick with the tq for now? is anyone out there using this combination?how is it?

if you really think i should go 2.4, what do you think of the acoms technisport. how will that handle the setup

appreciate your help
