This surplus wheel set comes with one motor, two sets of wheels (two standard, two wide plastic studded tires and plastic hubs) and four guide rollers.
This is technically a "Hypersonic Tune-Up Parts Set" that, according to the almighty packaging, will "Give SUPER-SPEED and STYLE to your HYPER CARS and RACING SETS." These sets come in a random pick of red, yellow, blue, green, or black wheels.
Check out our tested stats for the included "SUPER HYPER MOTOR" (we're lucky they didn't use any more awesome adjectives - it would have made an overload of incredibleness):
Current @ 1.5V: 900mA
Current @ 3.0V: 2.8A
Current @ 5.0V: 5+A (don't try this at home, kids. It's a good way to fry a motor)
RPM @ 1.5 V: 13,200
RPM @ 3.0V: 24,500
RPM @ 5.0V: Lots
Torque: (No stats yet. It's comin'!)
We highly suggest lubricating this motor with some light oil before use.
You might also like to know that this set is "compatible with hypersonic bullet cars and other 1/32 scale vehicles". We're not sure if anyone will actually find that handy or not, but there you go. Something you will find mind-blowing, though... The packaging further enlightens us "SUPER-SPEED MOTOR 344M.P.H TO SCALE". Awesome.
