Tex, just go with your first choice. The OS. Im not a fan of that brand, but i know that Jesse Walknhammer and Tony Dribble run them and they like them. The RB S7II is another great choice and will eb perfect in the Losi because of the acceleration the thing has, it will make up for the small lack of bottom. GQ is a RB man now and he loves his S7, ask him about it. Eddie Finck loves his B3 too, you really cant go wrong, but if you must go, go Italian route.
not in a buggy dude not in a buggy
they have a weird power band and need the truggy gearing, might be fine in a losi
Weird meaning alot of top end or alot of low end or something else? j/c

I thought you ran a 621p in your TTR buggy at one time?
no for some reason in the buggys they have this weird bog at the beginning that u cant get rid of, but Dave K and some other guys run them in the 8s and they are greats its a timing thing they cut the exhaust port too high and it needs some crank work to make it good for the other buggies but losi is a little different...RIPS in the truggy tho
I wouldn't buy anything from the kid selling that Radical anyway.........He's known as a decent driver but I can see him death revving the chit out of that thing waiting to get marshalled (for some reason I see him doing that from his online personality)........
I won't do used motors on ebay, that can turn very ugly a lot of the time.

Is it smooth/linear, or is it actually radical? lol, I'm curious, because the Fantom I'm buying from Chad is getting pinched at OS Rocket, Fantom FR.21 /Radical 621 is the same thing correct Mike? So I'm itching to feel it's power, I'm tired of looking at this thing on the shelf, I wanna see it scream bloody hell
