i used to rum one with the OS P3 plug and sidewinder.
They have so much power that you spend half the race chasing the tail. I'd recomend running a soft clutch and a higher gearing.
they dont have the top end of a .21 and they can guzzel the nitro a little

everyone i know that had one now runs a .21 instead. most i race with run a Ninja JX21, GRP 21 MRT, RB WS7 / C6, OS 21

i had one in my st-rr and it was good lots of power had great top end and would get 9.5 min a tank.but made the switch to losi 8t and it was way to much. the losi is lighter and the with the driving style of a losi its just to loose. but i would go with a .21.

I ran an os .28xz in my rc8 for kicks I could handle it and might put it back in. I am sure I have better lap times with my grp.21 but the fun factor is off the charts with the .28xz it is just crazy fun with the rc8.The .28 is bomb proof.

.21 or 23-28 for a tuggy? i have a 8t and was thinking of getting a .24 or25. my local track is way bigger than the tracks in use to running. i was thinking .25 would be good. but i dont want to spend $$ on a new engine if its not the right fit. roar says up to 21 for buggies and up to 28 for truggy. i think most truggies use 21's. any feedback on this topic?

Amen! I had a crazy modified v spec for a while and it was fun but truck is much faster for lap times and easier to control with the os speed motor pulling duties.
