ran my Viper and Ames2000's srx at a local farm. Only had about 200ft through the gourd patch before it got rough and had to shut down. Right now my Viper has waaay too much ski lift and transfer and the SRX doesn't have enough. He's just spinning, I'm just trying to keep the nose down. I'm not strapped down yet though, hopefully that will settle things down. pulls like a freight train though. I got some of the worlds worst cell phone videos but you can hardly make anything out in them.
