Topic: Slot.it HRS2 Project

This car started life as a Spirit Reynard Sport, a car that never lived up to expectations, at least on Scalextric Sport track, but I always liked the look of the car.  Bill's experiment with the HRS Lola got me thinking and here is the result.  A Slot.it HRS2 chasis kit and a offset motor pod were the starting point with the intention of mounting it in a Fly Ferrari 512S body to counter Bill's Porsche 917.  The body and chassis were not really a good fit so on to plan B. The chassis fit perfectly in the Spirit body and the rear body mounts lined up fairly well.  The front body mounts did not line up at all so some creativity was in order.  A central mounted post seemed the best solution and I just happened to have a melted Jag chassis (boiling water is tooo hot to use to straighten a warped chassis) so out came the Dremel.  I cut the front post out in a square that was sized to fit in the HRS2 frame rails and epoxied it the the guide flag mount.  It was positioned as far forward as the body would allow.  Since this is a HRS2 with a separate mount for the guide and the front wheel it was now just a matter of positioning the front axle to fit the wheel well.  Next was fitting a post to the bottom of the body, a spare chunk of model sprue and some more expoxy were all that was needed.

After fitting the front I used some 90' styrene and made brackets that screwed the chassis in two spots and to the body posts.  I elongated the holes for the body so some movement was possible.

This pretty much left fitting the slot.it 29K red end bell motor, slot.it 17 X 10 rear wheels and 17 X 8 front wheels.  Stock gearing was used due to the fact it was all I had (9p X 28c).   Only one part was left, how to fit the rear wing.  The original Spirit wing was damaged during shipping and is mounted in the chassis.  I had previously purchased a spare Spirit wing that was supposed the fit the Reynard but it turns out that it fit the Spirit Dallara instead.  I fitted some styrene between the mounting post for strength then used some lexan to mount it to the chassis using a screw through the HRS chassis rear body mount whole. I also added some sheet styrene to replicate the splitters that were part of the original Spirit chassis which gave it a more finished look.  The project is now finished.

I tried the car at BSCC on Tuesday and it ran pretty well, but the rear kept wanting to come around, so a Slot.it racing magnet was added along with a different set of tires.  The car was competitive 4.4 to 4.6 seconds but not in the same league as Monte's Ferrari.

Re: Slot.it HRS2 Project

Rico, Very nice job! Looks like a really clean and sanitary build! The laps times you ran with it are about two tenths faster than what I could run with my HRS based Porsche 917. Are you going to try it with a sidewinder offset pod to see if you can improve it's performance?

Re: Slot.it HRS2 Project

Bill- I only have one sidewinder offset pod at this time and it is installed in my Ferrari.  I am going to play with the magnets as it seemed a little slow down the straights and very stuck on the curves.  Kind of a slippery slope situation....
