That's why I appreciate the Eflite practice of using glow sizes in their electric motor designations for the larger motors.. The Power 25 is pretty much a direct replacement for a .25, for instance.
The smaller motors with their 370,-480 designations only mean something to someone who has used the equivalent can motors.
Standardization across the industry would make it a lot easier for everyone.
When I see a Great Planes kit I might want, but it specifies some motor in the specific to Great Planes nomenclature, I don't buy that kit, having no way of relating the spiffy name of the motor to what I'm familiar with.
