You can get a OS CVRX .18 from tower for about $95, and I also see them often on ebay for $89. You can get it in either rotary or slide carb versions.

IMO this is a much better option than rebuilding that 2.5.

the os i can get will be less the 50 bucks
so definatly worth adapting over and it is nip
just wondered if i would run into trouble adapting the linkage from my trx slider to the os rotory carb ,,i am athinking it will work bu using angled pcs the hooked into the throtle post hooking it directly to the throttle on the carb of the os,,
what ya think

You may ned some advice but I thought "need" some advice would be better so I changed it for you. :

I don't understand the difference in the .18 engines that OS makes. I want one, but I don't know enough about the OS models to know what the heck i am buying.
I would prefer one that is made for the tmaxx, and one that i could use a pullstart or shaftstart on.

One has a slider carb and the other one is a rotary carb set up, It depends on what Maxx you have wich application you need the older one is this one with the rotary carb.

Hope that helps you out

To get a rotary carb engine to work in a non-rotary carb t-maxx, you need new throttle linkage. Also, if it's a 2.5 maxx, you will need a new pipe and side exhaust header.

To get that $50 engine in your maxx is going to cost you about $80 unless you have parts on hand.

Here's the cheapest side exhaust pipe/header I found that would work on the maxx with little effort: Duratrax Tuned Pipe/Header

This is the throttle linkage you need, ignore the picture, the part # came from the pro-.15 maxx (old maxx): Pro .15 Carb Linkage

You will also need a clutch nut adapter thing:Clutch Adaptor Nut

I know this because I installed an OS 15 cv-r(x) in my 2.5 maxx when I had it. These were all the parts I needed and used.
