I havent built an rc for a while so I think I am gonna get the XT8 2009 spec soon as its avalable, and power it with a flightpower EON33 4550 6S pack, MMM and a Neu 1515 2.5D maybe with the heli fan, probably gear it around 46mph. I have not been around the rc scene for a while so I am wondering if that will be a good setup or if there is better stuff out there brushless system wise
