Here are some brief answers to some of the questions you may have about the care and use of your Yo-Yos.

  • What is a fixed axle yo-yo? What is a transaxle yo-yo? What is a ball bearing yo-yo?
Fixed axle yo-yos are called such because the yo-yo's axle does not in itself have moving parts. The axle does not spin independently of the sides. The axle spins in the loop at the bottom of the string. The fixed axles were traditionally made out of wood but other materials are also used. In a Transaxle yo-yo the axle has outer and inner parts which move independently. The outer part is actually the transaxle which spins around the inner axle. The string then hugs the outer part. These transaxles are made of various materials as well (brass, nylon, Teflon). Ball Bearing yo-yos are a kind of transaxle which uses ball bearings. A ball bearing consists of a inner and outer race which are separated by a series of small balls. Functionally fixed axle yo-yos are more responsive and are better at looping tricks, whereas transaxles excel at sleeping/string tricks. In general, sleeve transaxles sleep longer than fixed axles, and ball bearing transaxles sleep longer than sleeve transaxles. Centrifugal clutch transaxles (Brains, X-Brains, Black Mambas) consist of a transaxle and a clutch mechanism which opens up to allow the yo-yo to sleep when the yo-yo is spinning at high speeds, but as the yo-yo slows the clutch engages, stopping the transaxle from spinning and returning the yo-yo to the hand.

  • Why won't my yo-yo come back up?
Fixed Axle - Your string is probably too loose. Lefty Loosey, Righty Tighty applies in yo-yos just like everywhere else. Let your yo-yo hang down and spin it to the right just a bit. Now it should come back.
Transaxle - Many transaxles require lube to make them return. Use a little Yomega Brain lube or Vaseline Lip Therapy between the transaxle and the axle. In addition many transaxle yo-yos recommend double looping your string (see, How do I change my string?). If you have a Brake Pad Technology (BPT) yo-yo from Playmaxx you may need to change your Brake Pads.
 

  • How do I wind my yo-yo up? My yo-yo won't wind up, what do I do?
Because of the reduced amount of friction transaxles can be very difficult to wind up. One technique is to hold the yo-yo in your left hand and place your left forefinger in the string gap. Wind it over your finger three or four times and then remove your finger. Continue to wind the yo-yo. One throw down to clear the string is now in order and your yo-yo is ready to go.
 

  • Why won't my yo-yo sleep?
There could be many different reasons. Your throw down must be cushioned out at the bottom or the bounce at the end of the string will cause the yo-yo to rewind. Try throwing at a point three feet in front of you. Throws straight down are difficult to sleep. So the problem could be technique. If you have a fixed axle it might be double looped which prevents sleeping. Or the string could be woud too tightly around the axle. Let it hang down and spin it to the left to loosen the strings grip on the axle. On a transaxle the string might have slid between the transaxle/bearing and the yo-yo half. So check the yo-yo's string for those conditions.
 

  • How can I make my yo-yo sleep longer?
Practice! That's it. The straighter and more exact your sleeper the longer it will sleep. And the only way to throw hard straight sleepers is to practice. Oh, you want an easier answer. If you have an adjustable gap yo-yo you could make the gap wider. Or, you can clean your bearing. Use 90% and above Isopropyl Alcohol, Radio Shack Professional Tape Head Cleaner, Goof Off, even lighter fluid to clean out all of the lubrication from your bearing. Just soak it over night, shaking it occasionally. Sometimes repeated cleaning will be necessary. A clean bearing will spin longer. Bear in mind that these are chemicals and should be used with caution. And children should get parental permission and supervision before using any of these substances. And If you really want longer sleepers Practice!
 

  • Will adding lube make my yo-yo sleep longer?
No. Adding lubes such as Brain Lube, Zebco Reel Oil, Vaseline Lip Therapy, or other lubricants will increase response and decrease sleep time. No lubricant will increase sleep time. The fastest spinning bearing is a completely dry clean one.
 

  • How long does (insert yo-yo name) sleep?
As long as you can make it. Really. I mean certain yo-yos sleep longer comparatively to other yo-yos but skill is the determining factor. Some yo-yos are known for their long sleeps (Cold Fusion, Samurai, Mega SpinFaktor), but a truly skilled thrower with a Turbo Bumble Bee I'm sure could out sleep me with a Cold Fusion. And as long as you can make it sleep long enough to do a trick, what else matters?
 

  • When should I change my string?
Before it breaks is a good rule of thumb. Make sure to inspect the string where it makes the slip knot at your finger. Looping especially can weaken the string there. Also replace the string whenever it looks dirty or frayed or becomes stiff. After a while you will develop a feel for how long you can use a particular string.
 

  • How do I change my string? How long should my string be?
To take the old string off, pinch the string a couple of inches above the yo-yo and spin it to the left until the string opens up. Slip your fingers into the gap in the strings and slide the old string off. Now take your new string and gently untwist it until you can insert your thumb and forefinger in the loop at the bottom. Slip this loop over the yo-yo and onto the axle. Keep a little tension on the string so it retwists correctly. To double loop do the same procedure, but after you slip the loop onto the yo-yo, twist it once and put it back on again. Generally the string should be short enough that you can impart good force on a throw. One guide is to tie the finger loop at approximately your belly button. Bear in mind that everyone prefers something different on string length. Find out what works for you.
 

  • Does it matter what kind of string I use?
Some yo-yos seem to perform better with different kinds of string. Strings vary in both thickness and materials. Try various kinds to see what you prefer. Generally they are referred to by a type number which indicates how many individual strands are involved in making up the string (Type 6, Type 8, etc.). Most string is 100 percent cotton, but some combination poly/cotton string is also available. Examples include Spintastics Slick 6, Team Losi Speed String, and YoYoJam JamString.
 

  • What are the different yo-yo shapes? How does the yo-yo's shape effect play?
There are a multitude of different shapes in which yo-yos are produced. However, most yo-yos can be grouped generally into three categories. The first, and the shape which has been around the longest is the imperial (classic, traditional, tournament) shape. This shape yo-yo is characterized by a narrow string gap, and is considered the best looper of the three. The next shape is the butterfly (wing, GT, saber) shape. It can be summarized as an imperial yo-yo reversed. It has a very large string gap and is quite easy to land on the string. The other main shape is the modified (modern, flywheel, Proyo) shape. It combines the best of both worlds. Rounded rims make it relatively easy to land for string tricks, but its slim profile makes it an adept looper as well. In addition its rim weighting allows it to sleep for longer periods of time.

You may see other shapes as well, but most fall under one of the other shapes.In the Imperial family you have: Professional/Slimline (Duncan Professional, Duncan Alien), and Bottle Cap/Bulge Face (Russell Fast Eddy Shooter, BC Spitfire): In the butterfly family you have Hybrid/Slimline Butterfly (Variflex X-Game). In the modified family there is Coaster (like modified but with flat rims, Bandai HyperWarp). Also there are shapes rarely made today such as Satellite (Duncan Satellite), Ball (Duncan Sportsline), and Humphrey (Humphrey All Pro Style Yo-Yos). Novelty yo-yos often come in a Sculpted style (Tiger Electronics Star Wars Episode I Destroyer Droid yo-yo, Star Wars Epsode I Trade Federation Battleship yo-yo; Spectra Star Donald Duck, Freddy Krueger, Dinosaur yo-yos.)

  • Ouch! My yo-yo finger really hurts. What can I do?
Eventually you will develop a callous on your yo-finger that will protect your finger and prevent yo-yo use from causing you pain. In the interim you can use medical tape or Yomega Yo-Tape to protect your finger. In addition moving the slip knot slightly on your finger can give areas in pain some relief. Finally take breaks as needed until your callous develops.
 

  • What's up with those gloves I see some yo-yoers wearing on one hand?
Those gloves allow the string to slide easily over the fingers of your non-yoing hand, which facilitates many tricks. In addition the string can rub and cut the fingers of your non-yo hand, especially in humid weather. In that case wearing the glove protects those fingers from harm. Bear in mind that these gloves are generally worn on the non-dominant hand (left hand for right handed yoers, right hand for left handed yoers). Some yoers do wear one on each hand, but this is not usual. Additionally products have come out recently to provide protection for the yo hand (Finger Armor, Hyper Yo-Yo Glove).
