@ Magman, thanks for the welcome, i have been a veiwer and avid reader for a while :)
Hey thanks for your advice everyone, well to be honest i will do mostly road with it, but maybe a little offroad. i have my revo for mainly offroad and a little on road.
What is required for a conversion on a CRT.5? i havent found any on ebay UK so will have to buy a new one if i were to get one.
For electronics, you can go cheap with a MM and a 9L, or you can go all out with the MMM and a Neu 1509.
Some ppl are even using vxl systems.
I have a MM with a medusa running on 4s.
