magnum arf or predator
I have a Weston Magnum with the West 50V2 engine and I am very happy. I am pretty sure that the firts time you will use a West 50 engine you will not want to go back to use a OS.
The West 50V2 that comes in the Magnum Combo is a Webra 50 engine modified to Weston Specs. Its comes with a bigguer carburator and I think they has make some biguer ports and rise the exaust time. BOTTON LINE this engine screem the hell out of it.
Get the Magnum Combo, you can't beat the price and you will no regret it.
Good Luck,
Isaac
PD: Just rurious, were can I see a picture of the predator???
