Do Mega G chassis' have body clips?

Yes, but only the short Mega G chassis (1.5″ wheelbase) does. Like the Super G+, it too comes with a body clip to fit under older AFX bodies dating back to the early 1970s.

The Long Mega G chassis (1.7″ wheelbase) was created for use on more modern race car bodies only, specifically the Mega G Formula bodies, the Audi R10 and Peugeot 908 LeMans Prototype bodies. None of the Formula bodies made for the other chassis will fit on either of the Mega G chassis. The length of the Long Mega G chassis allows us to make the bodies more accurate to their real-life counterparts and only AFX has it!

How do the recent AFX chassis' compare?

All are close in performance. The main differences are:

  • Mega G: Lowest, lightest, most powerful, and 7% faster than Super G+.
  • Super G+: The reference standard until the Mega G. Handles great, good top speed and adjustable motor. 2% faster than SRT.
  • SRT: Super strong Neodymium traction magnets make up for its less sophisticated design.
  • Racing Turbo: Not as fast as others but bulletproof and fun to drive.

The SRT and Super G+ chassis’ are all significantly faster than the original G-Plus chassis created in the mid-70s. But some folks still prefer the slower G-Plus and Racing Turbo chassis’ with their lower magnetic downforce.

Another important point is body fitment. The Short Mega G chassis fits all full-bodied cars made for SRT, Racing Turbo, and the Super G+. However, Formula (open wheel) bodies, LMP cars (Audi R10 and Peugeot 908) and new GEN 6 NASCAR and some longer streetcars (like Mustang Boss 302) will only fit on the Long Mega G chassis. Also, none of the Formula bodies made for the other chassis’ will fit on either of the Mega G chassis.

What are the names of the different AFX chassis'?

  • T-jet (1970s)
  • Magna-Traction (~1975)
  • G+ (1975)
  • Super G+ (1980s)
  • Racing Turbo (late 1980s)
  • SRT (1990s)
  • Mega G (2007)


In addition to the above, there were at least two other earlier chassis’ made between the late 50s and early 70s though these were made under the “Model Motoring” trade name which was changed to AFX in 1971. For more info check out our History section!

What size are AFX car wheels and tires?

All AFX Front TIRES: 0.375″
All AFX Rear TIRES: 0.460″

Please note: Super G+ rear tires only work with the drop center wheel that comes with the car.

All AFX Front WHEELS: 0.275″
All AFX Rear WHEELS: 0.275″

Please note: These are also the ODs for the Racing Turbo, SRT and Super G+ fronts only. The Super G+ rear wheel is a special drop center design that can only be used with matching Super G+ tires.

What size/scale are AFX Slot Cars?

AFX cars are referred to as “HO” which is 1/87th scale. However, they have really been 1/64th scale since the early 70s and are still that scale today. It is likely that the reason they didn’t stop referring to them as HO was for marketing purposes and now it is just accepted.


Can I use old AFX products with new?

Regarding the cars, any AFX car from any era will work on any AFX track from any era, though the newest track type is the best and the current Tri-Power Pack is by far the most fun.

As for the track, there have been three generations of track type. The newest has been around since about 1979. We sell an adapter that connects to the prior track type (side lock style) which was around from about 1976 to 1979.

The original track type ran from the 60s through to about 1976. We don’t have an adapter for that track type but one was made back in the 70s and there are still some around. However, they may be hard to find.

Can new Track Clips work on older tracks?

Unfortunately, no. The underside of our older tracks is shaped differently from the new. Therefore, any pre-1982 AFX or Aurora tracks need different track clips than the one we sell.

Why is one controller driving both lanes?

Most commonly, because you’re only using one of the two Criss-Cross track sections included in your Giant Raceway. They must be used in pairs or not at all. Using just one on a set sends power to both lanes as if they are one continuous lane.

You may also experience this issue if you’ve made your Super International into a 2 lane setup and are using one of the two Terminal tracks as a regular track piece instead of plugging it into controllers and a power source. Simply remove the second Terminal track and you should be good to go!

If you are still experiencing this issue without having any of the factors listed above, there’s probably a short in your Terminal track. Contact our customer service team for more information.


Can AFX sets be used outside the U.S.?

Yes, however, the power pack that comes in all AFX sets is for use with an input power of 120v and will not work with 220v or 230v without a transformer. Though we do not have transformers available in any other voltage, an electronics store in your country should carry them. Failure to use the correct transformer will damage or destroy the AFX power pack and may cause serious damage to your electrical system.

What is the blue Track Pad for?

The Owner’s Manual refers to this 1″ by 1″ square of fine (200-400 grit) sandpaper which comes in every set in a small plastic bag with a spare pair of pick up shoes (depending on the set). Use it primarily to clean dirty pickup shoes or to clean track rails but only as a last resort. If the track isn’t cleaned after using the pad the metal filings left over will get picked up by the motor magnets and scratch up the plastic. Check out our maintenance videos on the best ways to clean your track and cars.

Though we do not sell the Track Pad individually, you can find a large sheet of it at your local hardware store for a very reasonable price.

What's the difference between the Power Packs?

The Standard Power Pack has come with AFX sets since the 1970s. It has one setting, 22 volts, which is great for our more experienced racers. However, for our younger racers, the Tri-Power Pack is extra fun. Introduced in 2007, our Tri-Power Pack allows racers to easily switch between three power settings: Beginner, Intermediate, and Expert.

On Beginner (using only 8 volts) racers can drive on most layouts at full throttle without the car coming off the track. On Intermediate (using 12 volts) racers can come off at full throttle in at least a few of the corners. On Expert (22 volts, the same voltage as our Standard Power Pack), the cars can come off pretty much everywhere.

Our Tri-Power Pack comes in all current AFX sets and plugs right into any AFX set sold after about 1980. This is the first time such a product has been made for HO cars and only AFX has it!

Why are the controllers smoking?

During production, our controllers receive a light coat of preservative before they’re packaged to prevent corrosion. Most of it evaporates completely but with about 5% of controllers, there is some residual. This residual can cause a small amount of smoke, and sometimes a subtle “electrical” smell as the preservative evaporates. Neither is at all harmful to humans and will disappear as soon as it evaporates completely, usually no more than 30 minutes of racing.

Smoking occurs most often on the Tri-Power Pack’s Expert level (the only level that generates the heat required for evaporation). If you are at all uncomfortable with your controller smoking, let us know and we will send you a replacement.

Why do High Bridge Supports knock cars off the track?

Even after following the directions to a ‘t’ stuff might not always work out exactly as planned. If your cars are getting knocked off the track when going under overpasses try re-installing them the opposite way you had them before. Turns out the high bridge supports still look correct even when they’re upside down!
