Default Slapmaster 2.2

Well, since we have "show-n-tell" going on. Here's some pics of my 2.2. My 2.3 is in the molding stages and should be ready for some testing as soon as next week. They hopefully should be ready for the public in late Oct. The 2.3 will have the new steering stops and will be able to use a 1.80 front tire. They are only offered as a conversion. So far, the MS2.3 is the standard designs. The Project X stuff is still on the drawing boards...it will be molded off the charts!

This has been a fun trip down memory lane. I have seen inline pack cars before. It's tough to get the weight back to keep the right balance.

I need to take some pics of one of my designs that well... didn't work out so well. It's a rear pod that pivots around the center points of the motor, effectively removing its weight from the pod. There is a center shock on the bottom of the car that controls side to side. It has a shaft that runs completely through both ends of the shock body with a single piston in the center with seals at both ends. It really needs pics to appreciate it. The car had some bizarre pod flexing under accelleration but it could thread a needle through chicanes.

OK, I went to the shop and drug an old relic off the shelf that you all might get a kick out of. Like I said, this car had a lot of time that went into it and it would be lucky if two batteries got tapped in for the ride. What I really liked about it, was front end. It was stolen from: ???

Any Guesses???


An HPI Road Star. That's right, a 10th scale pan car. I made a few tweaks and added some cross braces. The front end had some really inovative design ideas. You could pull the king pin out of the front spindle (which happened to be rectangular) and flip it over to go from inline axle to trailing or vice versa. It also had spacers that you could add under or above the spindle to change ride height... a concept that I use today. You could also add or subtract spacers above or below the upper pivot ball to change roll center. The upper hinge pin was replaced by a titanium screw that could precisely dial in caster... I forget the manufacturer that came up with that idea. The suspension had double A-arms that could use a front sway bar. I nicknamed it my "dot front end". It weighed about a 1/2 ounce more then todays Asc front ends, but the travel would allow it to tackle dots without launching the car into the cheap seats.

The rear end was machined from a solid block of aluminum. It pivoted through the motor axis which helped eliminate it from the sprung weight in the pod. The side-to-side dampening was controlled from a single shock located on the bottom of the car. The shock body has a ball stud mounted in it, which indexed into a bushed hole on the chassis. The shock shaft runs through both ends of the shock body and has seals at both ends. The tweak is done with nylon screws that run up against springs that press into the shock from both sides.

The batteries are actually stick packs. I have an 80 watt iron that has a flat tip on two sides that I could heat up two cell at the same time, remove the iron, slide the cells together to form a solid stick pack without any battery bars. The battery only had one battery bar across the end.

Changing the rear ride height required just a spin of the spring collar. There were no ride adjusters that are used today.

It's a neat car, but really just an amazing conversation peice!

Wow Brian, that is a pretty amazing piece... A piece of history of Slapmaster Tools!!! I would have never thought to have the pivot done like that. Pretty crazy stuff!

Yep, part of me wants to freshen it up and give it another try and then... there is common sense that says: let sleeping dogs lie. That car was hacked out by hand more then most will ever know. That car was well into a series of "customs". There was the original Monkey Spanker. That was a link car that is very comparable to todays CRC cars. There were two cars that predated that design. I can not recall if I even gave them names. I started this in about '93. Now look where it's got me

Posted up some pics of the Maverick 1/12 scale asphalt prototype on the Swift site. So far it's been running very well. Pics of the carpet chassis will be added soon.

www.swiftracingproducts.com Look in the Conversion Kit section.

Default Is "inline" better?

Does anyone have any results from the "inline battery" cars? I am getting into 12th scale and would like to buy a car that was different than the others. I am intrigued by the Goldrace and Darkside cars but dont know the handling attributes of the batteries "inline".

Someone please educate me.
