RE: Brushless help
I have a bone stock MX450SX, it is all pretty red aluminum and carbon. She is a smooooth ship. She is not the fastest, most 3D, ship around. She does fly really well. Stable and a joy to fly. I am running the $12.00 325mm carbons from Deal Extreme. I am using an Anon inrunner BL motor with heat sink. Head speed is around 2200 and just sits there looking good.
Sorry can not help with the motor, the scorp should be fine.
Dru.
