The Scarab’s Last Act
Building Midlantic’s Mid-Engined Scarab
by Wayne E. Moyer

Lance Reventlow’s Scarabs were pretty much unbeatable in American sports car racing in 1958 - and for that matter, after they were sold to Jim Jeffords and Augie Pabst for the 1959 season. Having beaten Ferrari and Maserati sports cars in West Coast racing, Reventlow saw no reason why he couldn’t beat them in Europe in Formula One racing. We won’t go into that ill-conceived effort except to say that it had a profound effect on Reventlow Automobiles Incorporated. The original front-engined Scarab F1 car was something less than competitive, even with Chuck Daigh at the wheel instead of Reventlow. Lance spent about 1.5 million 1960 US Dollars to build two F1 cars, several desmodromic valve engines that never performed to specifications, and a rear-engined F1 that never was raced. Reventlow may have been disillusioned by his lack of Grand Prix success; he certainly began to lose interest in racing as a “hobby” by 1962. His mother, Barbara Hutton, was tired of the continuing expense and the Internal Revenue Service served notice that RAI had to make a profit in 1963 or else. Reventlow began closing down the RAI shop early in 1962, but apparently decided to take one last shot at racing.
RAI had built a mid-engined car designed to Formula Intercontinental specifications. It had a 3-litre Offenhauser engine to meet the rules and was raced several times in England during 1961 with a total lack of success - nobody ever built a good sports car around the Offy engine. RAI still had the car, though, and was able to convert it to an SCCA-legal sports car by widening the chassis to make room for two seats and a mildly hopped-up version of the new Buick aluminium-block V-8 engine. Repco would make a World Championship engine out of the Buick in just a few years, but in 1962 it only had potential.
Lance managed a second place in a less-than-stellar SCCA Regional field at Santa Barbara on Labor Day of 1962, and then showed up at another SCCA Regional in Reno with the Oldsmobile version of the aluminium-block V-8 in the engine bay three weeks later. The Olds may have been stouter; the Colotti gearbox failed in practice.
Still, Reventlow took the mid-engine Scarab to the Nassau Speed Weeks at the end of the year. It was another disaster. Lance ran in 6th place until it started to rain whereupon he dropped back through the field before stopping in the pits to recruit Augie Pabst, who was quite fast in between stops to dry out wet electrics. Lance took the last Scarab home and never drove it again.
When the IRS forced Reventlow to sell what was left of RAI, Texas oilman John Mecom bought the remnants, including the mid-engined Scarab. He put another Texan, A.J. Foyt, in the cockpit. After running behind the King Cobras at the 1963 Riverside and Laguna Seca races, Foyt convinced Mecom to replace the Olds with a Chevy engine. Everything - chassis, driver, and engine - was now in place and the mid-engined Scarab’s true potential was exhibited when Foyt beat the Cobra team at Nassau and then beat everyone in the 1964 Daytona Continental. The last Scarab didn’t fare well after February of 1964; at least not until Walt Hansgen was put into its cockpit at Bridgehampton, where he was virtually unbeatable in any kind of car. Hansgen built up a lap lead on Pedro Rodriguez’ NART Ferrari 275P, but a 4-minute pit stop put Hansgen almost a minute behind. Within 10 laps the Scarab, now designated the Zerex Special, caught and passed the Ferrari to give the mid-engined Scarab its last major win. Mecom finally sold the Scarab to Augie Pabst, but the 1962-vintage car was no match for the Lola T70s and Chaparral 2s it faced in 1965. Augie brought the Scarab home in 5th place in the season-ending Stardust Grand Prix Can-Am race and then both he and the last Scarab retired from professional racing.
Midlantic Models produced every significant version of the front-engined Scarab and is well on the way to doing the same for the mid-engined car. Like all race cars, the Scarab changed from race to race, with a wide variety of scoops, air dams, spoilers, and even rear deck configurations to cover the three different engines it carried. From what I’ve seen so far, Midlantic has accurately modelled all the different bits and pieces on each version of the Scarab they’ve made.



MID030 Scarab Santa Barbara 1962 - Reventlow
The prettiest one of all, of course, was the original version seen at Santa Barbara in 1962, before a variety of drivers and crew chiefs began adding things in a never-ending attempt to make it go faster.
Midlantic’s kit (MID030) consists of a very smooth and nicely detailed resin body shell, 18 white-metal castings that include the baseplate, 3 chrome-plated castings, 10 photo-etched parts, 4 rubber tyres, a crisp vac-formed windscreen and the usual screws and axles. The exploded-view instructions are sufficient for this simple kit, but they do leave out an important piece of information we’ll discuss in a minute.
All mould lines on the body run along the lower edges where they’re easy to remove and there’s just some minor flash in the wheel arches and cockpit opening. The white-metal castings were equally good, so parts preparation literally took only a few minutes.
Midlantic doesn’t mention the two large holes on top of the rear fenders; brake cooling scoops were added there after Mecom bought the car (remember, he had A.J. driving). Kits for later versions have those scoops but this one doesn’t, so those holes should be filled with your favourite putty and sanded smooth before the body is washed. I also found - later - that while the baseplate fitted the body shell just fine, it made the rear track too wide to get the tyres inside the body. A couple of minutes with a file fixed that, but this one does need some “dry fitting”.
The first coat of primer revealed a few tiny “pinholes” on the lower edges and a small “glob” of surplus resin on one side. These presented no problems and may or may not be present on other castings. After a bit of filling and sanding, the second primer coat was smooth and ready for the colour coats. The instructions specify a colour with which I’m not familiar, but as far as I can determine all Reventlow’s cars were painted GM “Maui Blue Metallic”, a medium metallic blue. American modellers can get the correct colour from Model Car World; #5622 Medium Blue Metallic.


The instructions specify light grey for the interior, which looks to be correct. Ford Dove Grey was pretty commonly used for chassis back then (oil and other stray fluids showed up well) and is available from MCW, too.
The decals are very well printed and match Santa Barbara photos in Preston Lerner’s “Scarab” (THE reference for these cars) precisely - obviously Midlantic has a copy. They’re “tough” and require some Solvaset (SS) to get them to snuggle down, but by the same token they’re easy to move into position. They do snuggle down like a coat of paint with a bit of work. I disagree with one point - silver decals are provided for the “body latches” but I can’t see any evidence of them in photos so I left those off.
I had no problems folding up the photo-etched side panels or assembling the simple interior, but your task will be easier if you have the side panels in place before adding the instrument panel - don’t ask how I know that. The vac-formed windscreen fitted well. I did have an unpleasant surprise during final assembly - the inside of the front fenders is curved too much at the top, forcing the top of the wheels to bow out in an exaggerated “toe-in” condition. If you’ve read this before building your kit it will be easy to grind some material out of the wheel wells, but at this point my only option was to slice some rubber off the top inside of the tires - I never build my models to roll anyway.
There are lots of photos of this car in “Scarab” and Midlantic’s model matches all of them very well both inside and out. The clean, simple lines of this very first iteration of the mid-engined Scarab are virtually perfect and dimensions check out to 1/43 scale well. With Midlantic’s excellent front-engined Scarabs, Jade’s Formula One car, and now these fine mid-engined Scarabs from Midlantic, I have the entire Scarab history in my display case.
All of these models, by the way, are available from GPM! Why not ask them for a list or look up Scarab on www.grandprixmodels.com.
