Viper, BSRT and Wizzard are the next steps up or sideways on the peak as far as a USA factory made car and build

T-Jet

MG+ cost twice as much as AW because they are 4 times better. 

The auto world x-traction all have a problem with the rear hubs being off center causing a wobble or bouncy car…

The thunder jets don’t have that issue ……… but autoworld is only $20….. AFX at $40 is a great deal …… viper at $60 is super high quality and insanely fast ……

MegaG+ is super fast and uses 120ohm controllers that no other magnet car uses. That super international set comes with an adjustable power supply. It also comes with a lifetime supply of 6″ radius turns, so have fun picking your $50 cars up off the floor on the lowest power setting. Also, make sure you by track clips so the track will stay together.

Correct AW is slower…FYI, they offer 3 designs of chassis. I recommend Viper Scale Racong an improved SG+…you can get them with out traction magnets. Use Lexan bodies OR use an adapter for the older AFX bodies or any AW body that fits 1.5″. 

 They have new Mustang, Camaro and C8 Corvette molds coming out next month. They recently released new 2 GT40 paint schemes and 2 GT40 MKIV molds as well as new color of Ford GT. Hurry before supplies run out, the after market prices for some models are crazy. There are some ’69 Mustangs and ’70 Camaros out there as well as “70 Vettes. Have fun

This looks like it’ll fall apart and have problems quickly, so may not be a good idea… I like the lego combination with the slot cars. I like the true 1:87 scale so it’s comparable with HO trains whereas other cars are 1:67 or bigger… I like that it’s cheaper than the Carrera Build N Race sets and has more ‘floor pieces’ to build around the track, but at only 5 volts dc and a new player on the block that cannot even advertise correctly (on wal-mart’s site it says it includes batteries and in same description that it is usb powered and has no batteries) it seems fluky and a bad idea in general, at least for now. Some forums I’ve read about it indicate it may be an old mold from way back in the 1960s that got reworked… and there are reasons whey stopped using it back then… too small to keep balanced… also ready that brushes fall out of it easily and are a pain to get back in since it’s rolled instead of screwed in or something…. hmm….

giant raceway

I like that it can fit in 8×4 foot space, but don’t like all of those bridges that could crash cars or be so wabbly it’ll cause connection problems, or other issues. Reviews say it’s hard to get final pieces to fit together sometimes…. It does look interesting since it’s got some interesting curvature and height vs other layouts like international 39…. also all that height might mean slotcars just fly off and go break, time for new cars… hmmm…

international plus 12 ….

International 39

===

$578.81 at rcsuperstore.com vs 666.40 at afxracing.com counting shipping with the same 15 items… international set, 6 of the pair of 15 inch straights (12 total), 100 pack of the track clips, race barrier, yellow gt triple stripe, 2 of the 6 foot 120 ohm controllers, blue mustang boss, orange corvette, and liquid red fort gt. Still debating with myself if that’s enough or not to start out with. Going to try to use the 12 straights to do the ‘international 39’ layout https://web.archive.org/…/Layout/4×8/International-39.gif I’m still debating with myself if this is too much to start out with, but my wife says straights are needed for speed… Video over at https://youtu.be/MvVpnH6nCm8 seems to be the only video I’ve found on youtube with that layout. In the video he didn’t have all the straights so only did 2 lanes… Got a HO scale train set up next to this where it’ll go after I buy another piece of plywood, and have enough cash together to purchase (waiting on withdrawal from Entropia Universe to fund this which takes up to 50 business days or so – sold my 2 shops in FOMA in there for 150 more than I bought em, and also sold a rcouple of rare pets – the boxer and oratan axe for a bit more than I purchased them for a few years ago last year, so figure it’s time to get money out of the virtual world hobby and in to real hobby like this that I can share more with my kiddo one one one )… figure we only need 2 of the 6 foot controllers since only me and my daughter will be racing mostly. The other 2 lanes will be for visitors. Thinking about raising one side a bit to sneak a HO scale train under it or beside it but we’ll see… flat may be better for speed and fewer crashes? (I think I agree with my wife that wireless controllers could be fluky if bluetooth syncing is an issue which the tinkertoy video seems to indicate indirectly) (still very much debating with myself if the extra cars are worth it at cost over 30 each but that price seems to be less than from afxracing itself and walmart prices so I guess it is market value for the new cars… really wish they had an afx car in green or something. Orange is ok but is very similar to red for those of us with slight color blindness… primary colors of red, yellow, blue is ok, but need something else for that 4th lane option other than the regular formula stuff)… are the cars in the international faster than the mustang, etc. or is it all comparable when they all have the mega g+ chasis? Seems like formula 1 may have slightly better air resistance physical properties, but cannot tell if that’d make much of a difference? the free shipping on over 100 seems to make a big dent in price comparisons. Still very much debating if this is all worth it, but think it might be fun…. we’ll see. Not sure if this will be bought eventually later this year or it’ll wait… or be replaced with something like an air hockey table?!?…

prices at walmart are not much better than afx racing… on some items it may be a little difference, but still around 330 for the international set vs 248 over at rc racing, at least for now… may change around black friday?

This next track layout also fits on a single 4×8 foot table and uses the Tomy AFX Super International Racing Set in addition to one dozen 15″ straight track sections. This layout makes use of every track section contained in the Super International. This design packs a 39 foot lap length on to a simple 4×8 foot table.
International 39 Raceway

View Color-Coded Track Section Drawing
If you own the Tomy AFX Super International Racing Set and are thinking about building a permanent HO race track this is an inexpensive layout to construct. Just add a dozen 15″ straights and you’ll have an excellent raceway. The circuit is comprised of three fast straights with a technically challenging infield section.

The table below lists the Tomy AFX track sections required to build the International 39 raceway:
(24) – 15″ Straights (2)  – 9″ Straights (8)  – 6″ Straights (6)  – 3″ Straights
 (1)  – 15″ Radius 1/8 Turn (6)  – 12″ Radius 1/8 Turns (9)  – 9″ Radius 1/8 Turns(12) – 9″ Radius 1/4 Turns(28) – 6″ Radius 1/8 Turns
(2) – 15″ Power Tracks(2) – 22 VDC Power Packs(4) – Tomy AFX Hand Controls

4×8 – four lanes afx

4′ × 8′ Raceways – 4-Lane
 
This is the most popular size HO raceway. Built using a single 4×8 foot sheet of plywood with a simple 1×4 inch wooden frame, this size table provides a good platform for many challenging 2- and 4-lane raceways. See the Tables section for detailed construction information.

Scenic Hills 33
This first layout provides a 4-lane layout that fits on a single 4×8 foot plywood table. The overpass section allows for equal lap lengths of 33.50 feet per lane.

This particular layout makes a good race track for scenic landscaping. See the Table construction section of this web site for the plans to build this table. See also the Landscaping section for more information about this layout.

This circuit provides a fast 33.50 foot lap length with four fast straight sections and a challenging 6″ hairpin section. The center area on the table provides enough room to create a realistic pit row and garage complex.

Tomy AFX track inventory required to build the Scenic Hills 33 raceway:
(28) – 15″ Straights (8)  – 9″ Straights (6)  – 6″ Straights
(16) – 12″ Radius 1/8 Turns(20) – 9″ Radius 1/8 Turns (4)  – 6″ Radius 1/8 Turns
A longer 4×12 foot version of this raceway can also be built using the Random Lake 48 track plans shown later on this page.

A faster banked version of this raceway is also possible using the Elm Grove 32 track plan.
Ravinia 35
The layout illustrated below fits on a single 4 × 8 foot table and provides a lap length of 35 feet per lane. The infield section is fast and provides a challenging technical section. See the Construction section for step-by-step instructions for building this raceway.
Ravinia 35 Raceway

View Color-Coded Track Section Drawing

Cars travel counter-clockwise on the outer portion of the track. The main straight leads into a 90 degree right-hand turn followed by a 225 degree hairpin section. Upon exiting the hairpin the cars must negotiate a pair of 45 degree left-hand turns before accelerating down the infield straight.

A decreasing radius turn at the end of the infield straight feeds onto a short chute followed by a sweeping carousel turn before exiting out and onto the back straight. A pair of 90 degree left-hand turns punctuated with a medium-speed straight leads back onto the main straight again.

This particular layout incorporates many of the turn styles as described in the Design section, while still fitting on a single 4×8 foot table. This 4×8 foot raceway is my favorite layout for a smaller, flat racetrack. See the Scenic Hills 33 above for my choice of elevated 4×8 foot raceways suitable for authentic landscaping.

The table below lists the Tomy AFX track sections required to build the Ravinia 33 raceway:
(28) – 15″ Straights (6)  – 9″ Straights (8)  – 6″ Straights (2)  – 3″ Straights
 (1)  – 15″ Radius 1/8 Turn(18) – 12″ Radius 1/8 Turns(23) – 9″ Radius 1/8 Turns (6)  – 6″ Radius 1/8 Turns
This design is ideal for modern Tomy AFX slot cars as well as older Model Motoring Thunderjets. If you’re looking for a race track design that will be both challenging and still fit on a smaller 4×8 foot table this is a great raceway to build.

Elm Grove 32
This 4×8 foot raceway is very similar to the Scenic Hills 33 described above. However, this plan utilizes Tomy’s new 18″ radius turn, an increasing/decreasing radius hairpin turn at the end of the long straight and also provides for an optional banked turn.

Like the Scenic Hills 33, this track is also great for Landscaping

This challenging 4-lane racing circuit has even lap lengths of 32.48 feet for all four lanes and can be built on a single 4×8 foot table using the following Tomy AFX track sections:
(28) – 15″ Straights (4)  – 9″ Straights (6)  – 6″ Straights
 (2)  – 18″ Radius 1/8 Turns (7)  – 15″ Radius 1/8 Turns(14) – 12″ Radius 1/8 Turns(11) – 9″ Radius 1/8 Turns (2)  – 6″ Radius 1/8 Turns
HO Challenge
This next track layout was designed for the now-defunct HO DL Challenge. This racing series allowed you to compete with other HO Slot Car racers from around the world using this standard track configuration.

Because the track layout remained the same for all racers, lap times could simply be compared to see who the World’s Fastest HO Slot Car Racers really were.

This challenging 4-lane racing circuit has a lap length of 32.64 feet and can be built on a single 4×8 foot table using the Tomy AFX Super International Racing Set in addition to these extra track sections:
 (4)  – 15″ Straights(12) – 9″ Straights
(16) – 12″ Radius 1/8 Turns
(2) – 15″ Power Tracks(2) – 22 VDC Power Packs
If you have ever wondered about your driving skills or your ability to prepare fast HO Slot Cars this is a good means of testing your abilities against other HO racers from around the world.

Whitefish Bay 33
This next track fits on a single 4 × 8 foot table. It has a 33 foot lap length comprised of 4 lanes. This track was originally built using Tyco/Mattel slot car track sections, but could have just as easily be made using Tomy AFX track instead.

(14) – 12″ Radius 1/8 Turns (4)  – 9″ Radius 1/8 Turns(12) – 9″ Radius 1/4 Turns (7)  – 6″ Radius 1/4 Turns
Whitefish Bay 43
This next racing layout is a variation on the original Whitefish Bay 33 described above that provides a longer lap length of 43 feet with an infield comprised of two additional chicane sections. In my opinion this would be a better layout for older Aurora ThunderJets and A/FX slot cars due to its increased lap length and twisty infield section.

(21) – 12″ Radius 1/8 Turns(36) – 9″ Radius 1/8 Turns(15) – 6″ Radius 1/8 Turns
The Whitefish Bay 43 is also well suited to computerized lap counting and timing. The open area in the lower left-hand corner of the diagram above provides space for a computer display monitor. The 6″ straight sections at the center of the straight on the left side is an ideal location for a dead track section or photo-cells.

The track is designed so that the cars circulate in a counter-clockwise direction. With the start/finish line along the left edge of the table, drivers can glance up at the computer scoring screen as the cars pass over the lap counter and head into the double apex turn.

Tomy AFX 4-Way Challenge
https://web.archive.org/web/20190110180326/http://www.hoslotcarracing.com/ – original posted at


Purchasing a Tomy AFX Super International along with a 4-Way Split will not only give you the extra 12″ radius turn sections most track designs require, but will also provide you with a total of four (4) 22 VDC power packs, enough to power each lane individually. You’ll also get four (4) additional Super G-Plus cars. The 4-Way Split set includes GT Prototype sportscars as raced at Le Mans.

The first layout illustrated here is the Tomy AFX 4-Way Challenge. It combines the AFX Super International Challenge and 4-Way Split race sets described above to create a challenging 4-lane raceway with a lap length of just under 38 feet per lane.

This entire raceway fits on a single 4×8 foot table and can be built using only those track sections included in the two race sets. This race track makes extensive use of 12″ radius turns to create a fast raceway.
Tomy AFX 4-Way Challenge Raceway

This race track incorporates a technically challenging infield section to test both driving skills and chassis setup. Combining the International Challenge and 4-Way Split race sets provides a convenient and cost effective means of creating an interesting 4-lane raceway in a minimum of space.

See the Tables section for detailed instructions on building a 4×8 foot table suitable for mounting this race track. The total cost, including the two race sets and table supplies should be under $350.00, making this a great weekend project. See the Construction section for detailed photographs of the table building process.

A decreasing radius turn at the end of the infield straight feeds onto a short chute followed by a sweeping carousel turn before exiting out and onto the back straight. A pair of 90 degree left-hand turns punctuated with a medium-speed straight leads back onto the main straight again.

This particular layout incorporates many of the turn styles as described in the Design section, while still fitting on a single 4×8 foot table. This 4×8 foot raceway is my favorite layout for a smaller, flat racetrack. See the Scenic Hills 33 above for my choice of elevated 4×8 foot raceways suitable for authentic landscaping.

The table below lists the Tomy AFX track sections required to build the Ravinia 33 raceway:
(28) – 15″ Straights (6)  – 9″ Straights (8)  – 6″ Straights (2)  – 3″ Straights
 (1)  – 15″ Radius 1/8 Turn(18) – 12″ Radius 1/8 Turns(23) – 9″ Radius 1/8 Turns (6)  – 6″ Radius 1/8 Turns
This design is ideal for modern Tomy AFX slot cars as well as older Model Motoring Thunderjets. If you’re looking for a race track design that will be both challenging and still fit on a smaller 4×8 foot table this is a great raceway to build
