i'm also interested in the fantom 21s. i have 2 fantom fr18s and they are fantastic.

I would love to hear a review on them. I have yet to hear people talk about them in the buggy forums, which leaves me to believe they are less than pleasing.

Im thinking of getting one of those actually. When I do, I write up a full report.

JJJEEEFFFFFF

I've seen one run at my local, it was fast enough to ask what it was but not fast enough to go out and buy one. It didn't apear to have lots of bottom end but it had a fair bit of top end, (i didn't drive it, i don't know what clutch setup he was running). I was running a 421b at the time, that is such a fun motor to drive, a ******* to tune though. Need the right clutch set up to get it high enough in the revs, but nothing beats lighting the wheels up down the straight.

I now run a v-spec, very user friendly engine, my local track is now real tight and twisty, the motor works really well for the track. I'ld recomend this engine to people who can drive but can't tune real well.

ok i dont care if you could tune it well 2 much because whewn i need it tuned ill ask 4 help @ the track or go 2 my local hobby shop, i want an engine with good high rmps and good hp

if you want lost of low end power get a p5, if you want lots of top end power get a 421b, both from nova rossi. or if money is no object go buy a jp engine.
