dremelboy,

I was with CRF last season, bunch of reasons force me to make a switch to another engine brand.
More than a half of our buggy guys use RB, no one has been seen in nitro sedan class though...
Could you please give a basic explanation on differences between?

- R3
- V12series
- C12series
and
- MATRIXseries

What would be the best choice if looking for:
- Cheapest price?
- Best price / performance?
- Best performance?

Br,
J.
