Here is my new Can-Am/Coupe chassis... The Jackal. 

 

Ready to run weight is going to be right around 105.8 grams. Standard build will have a removable center weight (3.8 grams) making it easy to switch/tune between Coupe and Can-Am. The center weight is machined from standard brass while the other pieces are machined from half-hard .064" brass.  

 

Three standard rail configurations for this is .055" inner rails/.062" outside rails, .062" inner rails/.055" outside rails, and four rails of .062".  The last configuration I would only recommend for high speed tracks (like Port Jeff) as it will likely be too stiff on any other track. 

 

There is also a tutorial attached showing how I prep and build the chassis. Suggested retail for these is $65 and discounts available to raceways.

Nice!

 

A well thought out design that should be easy to build without tricky wire bends.

Very nice Dom.

 

Is the stated 105.8 RTR weight with or without the removable center weight and is the motor bracket angled like the Chicagoland or hypoid?

Hi Kevin,

The 105.8 is with the center weight. The motor bracket has a 2* angle like the Chicagoland.

Yes Dennis, 2-15/16" is the correct measurement for the bend in step 8. I'll correct the tutorial tonight and re-post it.

Here is the corrected tutorial for the Jackal.  Only change is to step 8 as Dennis noted for the length of the outside rail for the bend.

Took 2nd overall in coupe at the Retro East race at The Race Place in NJ.  The Jackal was set up with 15/16" guide lead, 3-15/16" wheel base, .055 outside rails, and .062 inner rails.  Race ready it ran at 111 grams.   Also set 2nd fastest race lap.

Took 1st in both Can Am and Coupe at NERR yesterday.  Racing was held at 1010 Raceway in Bristol, CT on their Olgilve King.  Ran the same car and just changed tires.  Thanks to David Panich and Woody Hazelwood for choosing to run their Jackal's yesterday too.

Congrats to Preston Selfinger finishing 3rd in the B-main Coupe Retro East race at Speedzone in NJ running the Jackal. Preston used the same car to win the C-main in Can Am and was running 3rd in the B-main before lady luck intervened. Thanks Preston for choosing to run the Jackal.

For those building the Jackal in the UK, here is the tutorial for making the removable center center weight to meet the UKRRA rule for center hinges.

New Rail design for the Jackal.  Qualified 9th yesterday at The Race Place in Farmingdale, NJ in Cam Am for the Retro East series race.  As usual with retro east the racing was really tight.  I took the B-main win and 3rd in the A-main.

 

7 rail jackal top.jpg   7 rail Jackal bottom.jpg

 

 

So here are some details about the design. It's been a couple years since I ran any car with .047 rails but thought it was time to revisit it after building the new Mossetti retro chassis for Bob Hughes. Chassis was built with a 15/16" guide lead, 3-15/16" wheel base, 6 rails of .047, and .062 center spine/wishbone design with .016 brass limiter in the middle. Ready to race weight with Koford wonder rears and JK fronts was 106.5 grams.

 

There was an obvious gap between the bottom of the brass and the top of the .047 rails. I filled this using bullet proofing to limit not only rotational flex but also the vertical (or bowing) of the chassis during high speed cornering. The chassis had a great soft feel to it for the Hurricane (an Engleman design) at The Race Place in Framingdale, NJ. The harder the tire I put on the more it hooked up! The body of choice of this design today was the Parma Ti22 NN short (#1050). The next tuning adjustment I am going to try is replacing the bullet proofing with either some .015 or .020 wire ran the full length.

 

If there is interest in having this design put in production please PM here or post on my Dominator Custom Chassis Facebook page. At 106.5 grams its a tad heavy for some Can Am racing but that can easily be fixed and I already know where the weight needs to be trimmed. Also please comment if you think if the nose should be slotted for 6 or 8 rails of .047.

 

Thanks to all the racers who ran Dominator Chassis yesterday at Retro East. I'll post Kudos when the race report comes out this week.

At Retro East at The Race Place in NJ this past weekend in Can Am Dan Wiegand ran a Dominator Ready to Race Jackal. Dan was running up front in the D-main until a guide broke. Thanks Dan for choosing to run the Jackal.

Slot the nose for 8 rails. Builders can then add a filler if desired or experiment with a split rail design

Congratulations to Josh Crutchfield taking 2nd in Can Am at Tri-State Slot Car Raceway at the ORS series race with the Jackal. Josh Also TQ'd using .059 inner rails and .062 outside rails. Josh's builds are well known and is a fierce competitor. Thanks Josh for choosing to run the Jackal.
