Default Thoughts on the HPI .12R XS

Anybody got any thoughts about or better yet, any experience with this engine?

I was thinking about this as a new engine for when I get a R40, but I haven't heard much about it.

-Solid power???

-Good power band???

-Good top speed???

-Easy to tune???


Thanks in advance for any comments...

All the mags love it.

I've heard that its an awesome club level engine, but its not up to the top motors at the top level of competition.

It's a STS engine.

I like STS engines, but they don't seem to be built as well as the Novas

As you may know I have a Nitro Star .12RSS from my experince with My HPI Engine it is extemely easy to tune It has two needles but I usually only tune one because I am kind of a newbie to nitro engines and my LHS advised me not to tune the lowend needle until I know what I am doing and from What I understand the .12R XS is a 2 needle carborator

Well when I took a look at the .12R XS instructions on HPI's website, it seemed to be a three needle carb. Although they suggest that you not adjust one of them from the factory settings.
