i'm the same, i can drive just as quick with sticks but i prefer the wheel. feels like you have more control somehow. imho the helios is the best steerwheel going, i tried all the others manufacturers before buying the ko and they just didnt have the ko's feel and balance.
i have heard bad things about the ko 2.4 stuff though, but not the spectrum. dont know how many others have had this but certainly i know of one case where the car was left on and the transmitter turned off due to a hold in the race, when the transmitter was turned back on the tx/rx had unbound from each other...
something to bear in mind....
splash out...go for the helios and spectrum 2.4 module!!
