Ditto the FMA Razor. I replaced a Graupner 400 with the Wattage Super 400 Cobalt 27T(gold or yellow, I not sure which), I picked up at a very reasonable price in RCU. Added a 7 x 6 prop and required a stouter ESC. A drastic increase in performance with approximately equivalent fly time. But given the Cobalt list price, if you can afford the difference, consider brushless. Steve W.
