Well its not acutally as small as a 450…the rotor diameter is 900mm compared to the 700mm 450 class or the 970mm 500 class….so we could call it a 475 class. Whatever it is…this is really cool of Walkera to shoehorn an nitro system into something so small. I saw .30 size motors in a 500 but this is amazing. At $549.95 ready-to-fly this thing is a bargain.
