Roger, i bet proper stumpy little fingers now after those two posts, there will be nowt left of them if you keep going
I haven`t driven a SP i have never driven any 4wd but the BJ4 WE, part of the reason i went for an aero, i really dont know if i will be any quicker with it or possibly slower

( i hope not, it would be an expensive mistake

)
I know though from watching people that a xx4 would not be the car for me as the people who are quick with them seem to be driving at 110% But the car lets them get away with it, I know i cant do that, i am super smooth, to the point i feel slow.
I also wanted a car i could be quick with a diff up front, this is something that i couldnt do with the bj4. I never thought of a SP to be honest and never really knew they had released a new model of the ZX5.
With regards to the americans moving away from AE and losi, well they dont have much choice really do they if they dont like the B4 and losi dont want the racers money they have to try the rb5, this is not saying its bad. they just have no other option apart from the x6 and i found this to struggle on dirt. (with a 3 gear box)
