      The weight has been increased from 60 to 75-grams. It corners amazing now compared to before! I can’t believe the difference. Like night and day. No more rolling over. It might not win the race. But it will be fun to try. And fun to drive.

        I tested the car today. It’s a fun car to drive with that Fox-10 motor. Art suggested a bit more weight should help it in the corners. It still needs decals.

        Wheels are Anthracite Gray in colour.

        I like the way this car sits. Slightly lower than the first one.

        As per usual for my builds. The rear tires were touching the inner fender wells ever so slightly when pushing the limits of the body-float. I have no clue as to why. I left at least .003″ of an inch clearance on each side. Art seems to find these mistakes instantly. After 5-minutes of sanding it was all good, and the tires were spinning freely with full body-float.

          The results of the first tests are in. To descibe it in one word would be “tippy”.

          Now to go from 60-grams to 75 and re-test.

          Originally looking at the kit, I thought this car would have a wider track. The fenders bow in at the front and quater panels bow in at the back dramatically limiting the track width. Never leave anything on the table because others won’t. I need to choose my builds a little better if I want cornering performance. I would hate for this car to become a shelf-queen.

          The alternative would be to build another 2-Tudors. Not that I like the car that much. But what an amazing slot car platform.

            Being a convertible, I can’t get away with just shoulders and head for a driver. That means making some sort of seat. The steering wheel was 1/16″ of an inch from the motor. So I had to mount the seat from the side. Just don’t open the door or the seat goes with it.

            Here is the clean body. Number 5 goes on it before it’s first race. Driver is Snydely Whiplash.

            It weighs 60-grams.

            It’s ready for the test run. Thanks for looking.

              Thank you very kindly Porsche911.

              I forgot to mention the dash and steering wheel is also going to be installed. That will show-case the right hand drive. If I’m not mistaken, I think the driver even has a British accent.  :good:

                It runs. I need to figure out how to get a driver in with a tonneau cover. Add a few more details (tail lights, door handles, inserts) and it’s completely done. Inserts are just set in place for the picture. They get full detailing shortly.

                The windshield locating holes were 1/8″ of an inch offset. What a disaster those windows were. I nearly ruined the car.

                 

                You almost need to lay your head on the track to see the chassis on this one.

                  Thank you very kindly. One of my previous careers was an automotive machinist building race car engines at Engineered Racing Services back in the early 80’s. Here’s a bit of info on engine specs.

                  The 427 cubic inch ZL1 engine actually had over 500 bhp — making it likely the most powerful engine Chevy ever offered to the public. Being an all aluminum engine, it weighed just 500 pounds — about the same as Chevy’s 327-cid V-8.

                  In 1971 Anatoly Arutunoff was attempting dominate the field of European cars with a Corvette Stingray that had incredible horsepower to weight ratio. His engine was well beyond street car specs. If the street version of that engine was already above 500hp. How much did Toly really have?  600hp? Too bad we didn’t get to see the results of that one.

                    There is a black hood. It’s on the unlimited class car.

                    I wanted to keep close to the facts on both Anatoly’s cars. His first one was a small-block 327 (Scalex). His second Corvette with the black hood, was a big-block powered all aluminum 427. The second white Corvette with the black hood will get a Fox-10 motor. Most likely my first aluminum sidewinder. It’s under construction.

                        I noted two Corvettes on the Targa Florio entry list that never made it. Rules are it only had to be registered to enter to race in S32. I really wanted to make one or both of these cars, but the rules say you need details. I combed the internet for any details. But because both cars never made it. There are zero records of them anywhere other than the cars were numbers 76, and 37 respectively, and the main driver was Anatoly Arutunoff. After 4-days of wasting time. The only thing I could find was a phone number through the yellow pages for an A. Arutunoff in USA. So one Sunday night I was brave enough to call his number and this is what I found out. Toly Arutunoff is a really nice guy! We talked for 45-minutes about the details of both his Corvettes. Here are the details of his cars.

                        1970 – 327 ci. C3-Corvette #76. All white. The car was caught in a stike dispute that happened at General Motors. It was a week too late to make it on the boat to Italy. This thread is in tribute to his first car.

                        1971 – 427 ci. ZL1 – all aluminum block and aluminum heads. Corvette #37. All white with a black hood. The car made it to the race, but was disqualified due to a technicality of the roll bar. One that could have been rectified had an Italian engineer signed off on the roll bar prior to the race.

                        Here are a few photos of Anatoly Arutunoff’s 1970 Corvette Stingray #76.

                          Thank you kindly JMS. What is this sleep thing you speak of?

                          The Tudor flew off the track like crazy at first. I added weight and the handling got much better. Then I remember a gentlemen showing up at Art’s vendor table at a model show. He bought all the urethane body washers Art had. Like 25 bags worth. That got me to thinking. So I added the urethane body washers to the Tudor, and the rest of the story is listed in the race results.

                          I bought an extra set of exhaust manifolds that twist straight back. But the stackpipe deserves it’s decoration. The car has body float just like the Tudor, and lead 3-layers thick jammed into the chassis. It still only weighs 65-grams. I can’t wait to test it.

                            Here are some detailed photos. This is the worst view of the car exposing the chassis. I’m not sure how the original plastic chassis fit but the crown is almost touching the inside of the body. The body post is so close to everything that it had to be carved to let the set-screw pass for the crown to rotate. NUTS!  :wacko:

                            Nobody’s eye should be that close to the back end of the car. This is how the car will look at the races.

                            Tight fit is an understatement.

                            I was going to leave the nose grill out. But it’s a unique BRM part, so in it went. Looks kind of cool now that it’s in.

                            A friend asked why I didn’t use the white background on the numbers. Slot cars are generally the only BRM’s with white backing behind the numbers. The real car rarely had them. Looks a bit more rough and race ready to me this way.

                            The aluminum chassis is evolving. Thanks for looking. I hope this inspires others to do the same.

                                I changed my mind and installed the bumpers. Too much red. Gold wheels just to be different.

                                I need to buy some number decals.

                                The original car was number 3, and was silver in colour. This red version will be number 9. Driver will be Mickey Thompson. Engine builder for Mickey was Smokey Yunick. The real car had a big-block 427 and was known as the “Mystery motor Corvette”. It was a fast car for it’s time.

                                I got brave and tried the chrome on the back. The chrome started to run in the circle at the center of the rear deck. I wish it wouldn’t do that. I didn’t even bother with the fuel injection emblems because they aren’t raised up high enough. Quit while I’m ahead. Too easy to ruin a nice paint job.

                                I heard about something called a “rattle pan” chassis. I am not exactly sure what that is, but I needed to add 10-grams to this car. Because this car is high enough above the track, I made a brass plate that sits under the chassis. I installed the plate, backed the screws off, then epoxied the threads above the chassis so they can’t back out. The plate rattles around ever so slightly. The car now weighs just over 100-grams. My curiosity is peaked on how it handles now.

                                  Please excuse the finish on the inside of the tires. They’re going back on the truer to get cleaned up before final assembly.

                                      This is a fun car to drive. Rarely can I relax while pushing a car.

                                      Weight was added to bring the car up to 80-grams. Makes a world of difference.

                                        It goes like a rocket! Fun but twitchy. We had to add weight to make it a bit more stable. The total weight is now 90-grams.

                                        Art. Thanks for all your help!

                                          I could have lowered the body a bit more, but prefer a somewhat realistic stance. Chassis is very close to the track on this one.

                                                After checking many photos. Very few racing Corvettes had bumpers, or side-pipes. So the bumpers will stay in the box. The tail lights will get get some work done when the chrome and livery goes on. I expect to handle and debug the car a lot at the test.

                                                              I had a major failure when I put a bit too much epoxy between the chassis and motor and epoxy got into the motor. Oops. Popped out the scrap motor and set the car aside until a new motor arrived. Now everyone knows why the build stopped. Something to do with a senior moment. The new Scalex 18k motor has been glued in place and spins nicely. I hope to have this car ready to run for “Tuning night at the Ring” this Monday. The idea of tuning night is a great idea! Ken

Hope to try it out for the first time this Monday night. This idea of “Tuning at the Ring” is amazing. This might be the first time I can tune a new S32 car before it races. Ken

The chassis went into the garbage. The body back in storage, fuzzy dice and all. Kind of funny now as I look back at this silly thread. Humble beginnings.

                                                                      Experiment A = 22k flat-6 geared at 9 x 26 = 2.88 ratio.

                                                                      Art has informed me that my cars so far have very little brakes. I want a taller gear ratio to offset the extra 2k in the motor, and increase braking.

                                                                      I’m crossing my fingers that this should work. I’m fairly confident the car will move in a forward direction. The question remains, will it corner well?

                                                                        Jim. It’s not really ambition. It’s the product of being a newbie and not knowing where the limits are. It’s too easy to install these motors. I may regret it. Am I really the first one to try this kind of thing? Hard to believe.

                                                                        If there’s a pile of crown gear material laying on the track after a few laps. I’ll know I went too far. Chris Walker has a car with an inline drive and angled gears. Looked very inspiring to me. Something to consider if this drive system starts to tear itself apart.

                                                                        SP+ is open. Why not experiment? I can always change the motor. They pop out in less than 2-seconds. Takes 2-minutes to clean the remaining epoxy. Then mix another batch of 5-minute epoxy and another motor is installed. So long as the replacement motor is a slim-line (or thin like a flat-6), it will fit.

                                                                        The aluminum chassis are dedicated to either an S-can or slim-line motor based on axle/pinion height. Beyond that I can move around within either style of motor by popping the old one out and gluing in the new one. I figured that out when I ruined a motor and had to replace it before a car saw the track.

                                                                        Like the songs goes… She’s my “lil’ red Corvette”. This experiment should be fun!

Corvettes were all potentially fast. Installing a different motor is a matter of reaching to the left or right side of the chassis once the 5-minute epoxy is mixed. Flat-6 here we come!  :yahoo:

The livery had to change due to it being too different from Mickey Thompson’s actual car. Fred Steinbroner is the new driver of car #18.  I added 7-grams of lead to the chassis. The final weight is just over 75-grams.

                                                                            I didn’t like the car at first. However, it seems to have earned my respect, and a solid spot in the “Hot Rod Garage”.

Art barely even touched the edges of the tires with 2000 grit sand paper and the Ferrari was half a second faster per lap, and become a pleasure to drive. I can’t believe the difference.

Hard to find something that fits 15’s front and 17’s rear. The only thing I’ve found in gold so far from Slot-It is BBS style wheels.

The red brake lights and amber turn signals would not pop as nice had I blacked out the lenses. Nothing more fun than having to paint with a tooth-pick. That takes more patience than a good ketchup.

Hard to use the Molotow pen without making a mess. I started taping around the louvers until the decal lifted. Then switched to hand painting the black. Big mistake. Paint the louvers first next time. This will be my first and last time hand painting louvers.

Something the size of a pencil eraser that weighs nothing will go as fast as a flat-6. Scary thought. It’s one thing to have a car hit the floor. It’s another when they leave dents in the drywall. Splat!

That might fit under all the bridges without having to change the suspension. We’ll see what happens when the build continues. I look forward to it.
