OK. I have had my CEN MT-2 for some time now and I am becoming a huge fanatic for off-road rc. I would like to upgrade it to optimum profomance but I am running on aExtreamy tigt buget. I have herd great things from Nova rossi and there tuned pipes but have not found a pipe for 1/10 off-road. I was also thinking of some aluminum brakes and ball barings. Anything els that could help for a low price.

Yes I will buy a new radio....

you can get the metal disk brake kit from cen for under $5. you may want to look into the dynamite mach .26. it has the mounting dimensions of a .21 but much more power. it goes for about $140 w/PS.

and about the radio, smart decision.

and it wouldnt hurt to upgrade the steering servo to one with metal gears. i have the futaba S3305 metal gear servo. it costs $35 at tower hobbies.

i would make a mount for a .21 os best engine i've ever had and im would buy a new tranny.thats just me.go to towerhobbies.com they have good stuff for cheap.
