The size classes come from an old convention of naming things based on the size of the motor... not the power or anything, the actual physical size of the motor. A 400-size motor used to be a well-known thing - there is a pylon racing class called "Speed 400" which requires the use of a 400-size motor. With brushless motors now on the market though, a 400-size motor can be way more powerful than the old brushed motors, and still be technically a 400-size motor.
Now obviously, running one of those in a Speed 400 race against guys using the Cobalt 400... is gonna be a little unfair. So really, the classes don't mean a whole lot of anything anymore, but they have a historical meaning.
These days though, the size classes are still used, and while they are somewhat ambiguous, they are less useless than the class names such as "mini" and "micro"
And as has been pointed out, the best objective comparison method is to use blade size.
less than 200mm blades - 100-class - "ultra-micro" - (Blade mSR)
200mm blade - 200-class - "micro, or sub-micro, I don't know" (Trex 250, Gaui 200)
290mm blade - 300-class - "micro, I guess" (Blade CP, Honey Bee)
325mm blade - 400-class - "mini" (Trex 450, Blade 400, Mini-Titan)
425mm blade - 500-class - "helicopter sized?" (Trex 500, Protos)
600mm blade - 600-class - "large electric?" (Trex 600, Mikado Logo 10)
There are some blurry lines there... |
