Default is the trx2.5 worth it?

i right now have the 2.5 and i here people complain about it. so i was thinking about upgrading to a os "can never go wrong with them." so would the .12 CV-RX be a good replacement for it? i would go with sumthin like the .12tz but it is too expensive for me.

the cv rx i bought did not fit between the motor mounts on my rusty but it is a pro 15 one, but i had a backplate for it anyway.

hahahaha, 17 minutes per tank. yes 17 minutes on a 75cc tank is crap my mate gets 34 minutes with his novarossi. hahahaha. nuh its great really. but i am replacing all my bearing with ceramics soon, so fix up a few air leaks.

but in all seriousness i DO get 17 mins a tank. so rest assured its good.

Either you run that engine really lean or you dont like hitting the gas that much. O.o

Anyways, I have a Traxxas 2.5r engine and I have had no problems with it. OS i have had no problems with. You need to break them in diffrently though.

i run 25% nitro and just 8% oil so my end point leaves the carbie at only about 60% when wide, which is all it needs as the powerband is there way before that.

i only get about 10-12 minuets per tank on the 2.5. 17 is alot better then what im use to. it also could be that it is a smaller engine though.

the 2.5 has more power, dont expect the same wheelstands out of the cv r but the cv-r is a smaller much more responsive revier engine.

will the tz fit in my rustler? the rustler is a rear exhaust when the tz is a side.


btw, yes i am dropping my engine size, but i will gain more. its not torque that wins the race, its speed and acelleration
