Mega motors/APC props
 

I got two questions for you R/C Wizards! First, on the Mega brushless motors, what do the numbers mean? (i.e. 16/15/7). I see that this series of motors is said to out perform speed 400 motors, in the same size package. The last number indicates what?
Alright, one more. The APC props are available in "Slo-flyer" and "Electric". The Electric series is
much heavier and less flexible than the Slo-flyer series. What is the performance difference?
Is one for stunt flying, and one for speed, or what?
Thanks a bunch!

Don't confuse yourself with the numbers. In the grand scheme of things, they are meaningless. They're just model names, like Chevy Tracker or Dodge Neon.

What the numbers are, are rotor diameter in mm, rotor length in mm, and number of turns of wire in the stator. You can't really use these numbers to compare anything, especially between different brands. Like I said, the numbers are meaningless.

The hard part is figuring out which one you need. Don't be afraid to ask for help in this. It's all very confusing, and definitely not a simple process.

The APC props are for two different applications. Slo-fly props are for slow fliers, where the propeller RPM is less than 5000, IIRC. Thin-Electric props are for higher performance applications, and provide more efficient thrust than the same size glow props.

The 16 size cans are roughly the same size as Speed 400s
The higher the second number the more torque the motor can generate.
The third number is the number of windings of the motor.

A lower turn motor will turn faster than a higher turn motor with the same voltage applied.
i.e. most Electric Ducted Fans use 1 or 2 turn brushless motors.

Mega Motor Usa's website list several applications for each of their motors.
