Yes The CRF's are little out of my price range. I dont have much experience in nitro engines. I have the racing bug bad so I looking for a nitro engine that is going to be competitive, reliable and great fuel economy. The guys in the local club lean toward OS engines almost unanimously. I always try to be a little different and they like to bash the italian engines. I am also lookiing at the Werks B5 and the Alpha Discovery
