Which Engine?? I have a .15 Nitro sport that needs a new engine. I dont want to much wheel spin because I am using it on a very lose dirt tracks. I am thinking about a .15 O.S. engine and do not know which version to put in it. Can anyone point me in the right direction?

the cvrx are a good line i have 2 .18's and 1 .15 and they run like tops lots of power and easy tune and holds a tune very well

http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXGGP8 Thats the os .18 cv rx s it should be just a drop in replacement for the trx .15. If you are worried about too much wheel spin, then loosen the slipper clutch or go easy on the throttle.

if you on a tight budget- go for the traxxas engine replacement..and that only costs about $110 with shipping...and if your not go with a O.S. .18...and they run inbetween $140 to about 210 depending where you purchase the engine from..

hope this helps

since your racing go with a CVR .12 it's a lot cheaper (109 or less), will hold a tune better and will get better gas mileage...also will not light the tires up as easy as a .15 or .18 or the 2.5 [sm=rolleyes.gif]

I agree. The .12 cvr is a great engine and sounds perfect for you. If you wanted a little more power you could go with a fantom fr12.

Well i am not the owner of the truck it is my friends. I already know a 2.5 has to much power for loose dirt track...lol. But he said he wants nothing smaller than a .15, so could anyone post the link to the right O.S. .15 engine.

Thanks Blitzz!

You can get an OS .18 CV-RX for $110.

One thing is for sure you cannot get a more friendly user engine then and OS. Yes there many out there faster but OS tune easy, hold a tune and are very durable.

The OS .15 CV-RX has been out of production for quite a few years now and the OS CV-X engines with the square head are great engines just way under powered. I have one of the old discontinued .15 CV-RX and I am still running it. The OS .18 CV-RX took the .15 place and does not have a lot more power then the .15 so that is the one I recommend.

OK He said he will go with the .18 but now I need the right shaft to fit the Nitro sport clutch on. Does the link above have the right shaft on it or not??

Thanks Blitzz

check out www.stormerhobbies.com for the peak diablo 15 or 12, its so damn cheap its not even funny, its full bolt in, and ive raced them, they go, they keep with my novarossi. great engine good tune the lot thats my next engine.

I have found the right O.S. .18. He will be ordering that along with a new radio system soon. How much more power does the O.S. have than a 2.5r???

Blitzz

not much if any, just MASSIVE INSANE torque

If you want all out speed and want to compete with even the 3.3 get am OS. .18 TZ.
