1970 brought with it a total of thirty-three new castings, two new series and a Club Kit that could be purchased for just $1.00 through a mail-in offer. The first series Mattel introduced this year was the ever popular Spoilers series. These souped up muscle cars originated from some of the original sixteen Custom castings and were modified to include powerful exposed engines, large racing wheels in the rear, air spoilers and door numbers and stripes for a super fast racing look. These Spoilers were on their own blister card that featured art work of a Boss Hoss against a yellow background with the Hot Wheels flamed logo above. The second series folded into the mix of castings offered was the Heavyweights series. These futuristic work horses were similar to each other in style but very different in function. The Heavyweights also had their own blister cards featuring the art work of either a tow truck, a cement mixer or a fire truck. Mattel sponsored two legendary race car drivers, Don Prudhomme and Tom McEwen, whose funny cars “The Snake” and “The Mongoose” were scaled down into the 1970 lineup. They also had their very own blister card featuring art work of their two funny cars. Two new castings were introduced to the Grand Prix series making for a total of eleven to choose from in 1970. This year Mattel offered membership to the Hot Wheels Club. Each member received a Club Kit which included an iron-on patch, annual newsletter and one of three chrome Spoiler castings, the Boss Hoss, Heavy Chevy or the King ‘Kuda.
MORE ON THE SPOILERS SERIES
Mattel introduced the Spoilers series in 1970 with the release of five new castings. Three more were released in 1971 making for a total of eight to collect. It is believed that the U.S. tooling that made the 1968 Custom castings was modified slightly for each of the Spoilers castings. For example, the tooling of the Custom Mustang was the basis for the tooling of the Boss Hoss. The hood was removed allowing for an exposed engine bay and blown engine, and the rear panel that was cast onto the body was removed to allow for a new rear panel cast onto the base with a large spoiler. The same is true for the other Spoiler castings including the Light-My-Firebird, where in addition to the removal of the hood, door lines were added to the Custom Firebird tooling for change and more detail to the exterior. All Spoilers castings exhibited the same characteristics which included large front and rear spoilers (airfoils), large rear wheels, exposed blown engines, stripes over the cowl, roof and trunk and door numbers. Each Spoiler also included a water slide decal sheet that consisted of sponsor emblems. The Spoilers series of 1970 consisted of the Heavy Chevy, King ‘Kuda, Light-My-Firebird, Nitty Gritty Kitty and the TNT-Bird. The Boss Hoss, Evil Weevil and the Sugar Caddy joined in 1971. For further details on any of the Spoilers, please see their respective casting essentials found under the 1970 or 1971 sections.
MORE ON THE HEAVYWHEIGHTS SERIES
Similar in style, different in function, and heavy are what these trucks are all about. The Heavyweights design comes in three forms, each having a sleek cab that is similar to one another. First, the shortest of the three, is an attached cab and body design where either a tow truck bed, an open trailer bed, an ambulance or a cherry picker are fastened onto the rear. Second, a slightly longer attached cab and body design with either a fuel tank, cement mixer, dumper or waste container are fastened onto the rear. Lastly, there is a two-part cab and trailer combination where either a moving van, hook and ladder, a flat bed or a camper trailer connects to the rear of the cab by a swivel making these the longest of the Heavyweights. Each casting was on one of three blister cards. The shorter Heavyweights were packaged with art work of a tow truck. The medium sized packaging had a cement mixer and the two-part cab and trailer Heavyweights had art work of a hook and ladder fire truck. The first six Heavyweights introduced in 1970 and an additional seven in 1971 made for a total of thirteen exclusive to this series.
One Heavyweight that stood out from the crowd was the S’Cool Bus. This casting, released in 1971, was based on a model kit that Tom Daniels designed for Monogram. This yellow school bus features a pop-up body to reveal an orange air scoop on top of twin blown engines.
Although the Funny Money casting released in 1972 was to be a part of the Heavyweights series, Mattel discontinued this series prior to its introduction. For further details on any of the Heavyweights, please see their respective casting details found under the 1970 or 1971 sections.
MORE ON THE CLUB KIT
Mattel offered the Hot Wheels Club in 1970 and membership was just a dollar. Included in the kit you received was a club magazine, an iron-on club patch, a club certificate and a chrome club car exclusive to this offer. Originally the special chrome car included was the Boss Hoss, the first time this casting was released. A little later, two castings from the Spoilers series, a chrome version of the Heavy Chevy and King ‘Kuda, would join the Boss Hoss, making three exclusive castings available to the Club Kit. In 1971, the Boss Hoss would join the Spoilers series and was available in several different Spectraflame colors. All club cars came with a white or dark interior and had black stripes across the cowl, roof and trunk and white circles on the doors printed with a number ranging from 1 through 9. It appears that Mattel overproduced the Club Kit as they did make their way into stores. Plus, due to the abundance of chrome cars produced, you can occasionally find an “over chrome” example in any of the three castings. The term “over chrome” refers to a Club Kit car that has Spectraflame paint applied over the chrome. These are typically easy to spot as they have a real vibrant, reflective shine compared to the same casting that is not painted over chrome. Furthermore, these “over chrome” cars will not have any toning. For details on any of the three Club Kit castings, please see their respective casting details found under the 1970 or 1971 sections.
MORE ON THE SKY SHOW AND FLYIN’ CIRCUS TRACK SETS
Two very well-liked and quite exciting track sets introduced in 1970 and in 1971 were the Sky Show and Flyin’ Circus sets respectively. The Sky Show set that sold in Canada came only with a Deora, while all other sets sold elsewhere came only with the Fleetside. The 1968 Deora and Fleetside castings were slightly modified by the addition of an orange ramp mounted to their rear beds. This orange ramp has a slot in the middle that will secure a stunt plane by a launching tab located on the bottom of each plane. Mounted on front of the ramp is a rubber band which is secured to a notch on the launching tab and is what propels the plane when the stunt tab is triggered by the track trigger. The Sky Show set comes with a total of six planes, two blue, two green and two yellow. Each color plane will perform a different stunt such as a barrel roll, loop-de-loop or a soaring glide. The Flyin’ Circus set comes with only three planes, one each of blue, green and yellow and includes a Zoptet-Port with two Zopters which happen to be stunt helicopters. Mattel also made available the Zopter Pak which was sold separately. Both the Sky Show and Flyin’ Circus track sets are difficult to find complete and are popular sets among collectors. For further details on the Sky Show set, Flyin’ Circus set or the Zopter Pak, please see the Track Sets & Track Accessories section.

Casting Details:
There is no difference in value for black versus white interiors. In addition, this casting was used in a promotion for the Jack in the Box restaurant chain and included an exclusive decal sheet. This water slide decal sheet consisted of red stripes for the sides, a red circle printed with the number 1 for the rear and the Jack in the Box logo to be placed on the nose. These were mostly packaged in a baggie but some can be found in blister pack with the decal sheet stapled to the card back. The easiest way to tell the difference between an original decal sheet and a reproduction is by the color of the Jack in the Box logo. An original has a clear background where a reproduction has a blue background. The added value for the Jack in the Box promotion is merely in the decal sheet.
