I currently have a CEN ATX and i have the option of trading it (along with some other stuff) for a Traxxas Nitro Rustler with an OS .18 or a stock XXX nt. If anyone has any opinions on which trucks are better for jsut bashing and offroading please let me know, i will not be doing any racing. Thanks.

the rustler is great for both

and with that engine it makes it twice as good

Truthfully either choice would do just fine. But since I am a rustler owner, I am obligated to say the nitro rustler. That is also a decent engine, and will last long.

go with the nitro rustler, xxx-nt is made for racing, thats what people use for racing, but the rustler is a straight up basher

i drive a cen, but just for the engine i would go with the rustler as ive heard a lot about it bein a good basher - and the os engine is a belter if its the cvr...

arent all the OS.18 engines cvr, i know theres a TZ but oter then that they are all cvr?

Well there are many different models of os engines. CV-RX, CV, CV-X CV-R, TR, and maybe a few more. And those are just the car engines.
