Greetings. Where do you race?

I would be glad to help. Send me your email and I'll write up the details. James@mcpappyracing.com

New updated version of our Pinion Trees has just been released. They now have a 2-tone aluminum core color! We machined the edges after anodizing for an improved look. We also machined the numbers...

It's not a problem. You'd just put the servo tape on different sides of the speed controller.
Or if you run the Pro RTC class, it uses 2S (2 cell) with a 17.5 motor and you can use a tiny $55...

Yep, it works great. I'd recommend softer side springs. Most importantly, keep the speedo where it should be. Stand it up vertically if you have to. That is much better than putting it on the right...

This can be a lot of things, but theoretically, you'd want thinner side shock oil. Continuing to turn after the corner can caused by the car staying leaned over too long after the corner. Thinner oil...

This will convert your small 7mm pan car bladder shock (Silva HSP2, XRAY X12, Hot Bodies Cyclone 12, CRC Encore Micro shock, etc.) into an emulsion shock. Emulsion shocks provide instant...

Dominic Ruggiere won the Pro Modified A-Main and took 4th in the 10.5 Open A-Main which makes him the overall Oval Cup Champion. (He was heading for 1st or 2nd in the 10.5 race, but got spun out...

Yes. We have some customers using it for the Baja. We now offer a 21" version.

Very well thank you. More than just RC racers like it. We've sold them to electric skateboarding companies, NASA, and even Duracell is testing their batteries in toys on the our dynos.

I see them come up occasionally on RC Carpet Oval Racing group on facebook. https://www.facebook.com/groups/746227722076899/
If you are looking for motor to motor only, like this one:...

I'm happy to announce a project I've been working on for a while. The new dyno comes in 3 different sizes, 2WD and 4WD, chassis testing or motor to motor testing, 4 different load levels, built...

The COT bumpers have been redesigned and are back in stock. We removed the tungsten section on the left front, changed the 8-32 slots to holes, and now are using 2.0mm carbon fiber instead of 2.5mm....

We are happy to release our latest Helping Hands tool. The Helping Hands hobby vise was designed to hold small parts, models, crafting, hobby items, hold items for polishing, jewelry, circuit boards,...

The rollout mentioned above is probably going to be about right for you. You might be even higher than 4.50 since your track is slightly bigger. General rules of thumbs: More motor windings = more...

It doesn't matter what side shock you run. Length is the same. Fully extended pivot point to pivot point is 3.00".
AE oil is usually 30-35wt. Silvas are usually 70-80wt for the same feel.

Absolutely. The Mcallister body weighs a ton more.
Protoform all the way.

Thanks for helping. I will look for it. I can give you better images (more up to date) than the current sheet.

When someone says 10k, it's a machining term. It's an easy way to write 10 thousandth's of an inch (aka "10 thou"). So 315k (315 thou) = .315".

AE shocks are used by most of the top drivers, but it's a personal preference. Instead of thinking of it like, which is better, think of it more like, don't change a known setup if you don't have...

Congrats on your successes! The steering blocks are .345" +/- .010"

The ORC HD-2500 has a slight V shape to it. That's probably what you are referring to.

Yes we do.

For $100 more, you get about $180 worth of goodies by going from the Standard kit up to the Team Kit. Examples of things you get:


All aluminum screws (saves 1oz of weight so you can use more...

At this time, we don't have any in stock, sorry. I'm not sure of the time frame.

Sounds like you choose the wrong motor screw hole selections because our cars can fit huge gears. With that 96 spur, you can fit 80T pinion (64p). I recommend one motor screw on top, one on the...

It's the same formula as before. Nothing changes.
Tire Diameter x 3.14 x pinion / spur

To find the equivalent 84 pitch gear to a known 64 pitch gear:
There are approximately 32% more teeth on 84...

3.00" (from pivot point to pivot point.)

This is the new McDominator 2.1 chassis that won Snowbirds. During testing, we called it the Dominic 2.1 because Dominic lead the testing along with Ryan and Chuck. Ed Baggot and a few others tested...

Ryan Weeks TQ's and wins the largest class Stock Spec 13.5 at Snowbirds! 90 racers in that class! On the tone, he pulled away and lead the whole race unchallenged.

We just added 2 new products to our web store:
McPappy Racing 45x3mm aluminum turnbuckles are lightweight and are the exact length needed if you are using TC6 eyelets on a 1/10th pan car.
We...

A flat servo is harder to get bumpsteer solved because it's hard to get a good angle on the right turnbuckle. It usually requires using lots of spacers underneath the ballcup/Dubro/TC6. Usually you...

What chassis are you running?

What do you mean when you say "Now I'm starting to go for a better roll center" and "a ton of LF jacking force."
As for contact patch on the straight, my personal testing has revealed that it was...

This CNC machine is the latest addition to our McPappy Racing team. It will help our team test prototypes faster. I've had the CNC machine for a couple of years, but I just finished designing and...

Since you are running Spec tires, there's not much you can do. Here are a few tips to reduce tire grip:


Smaller diameter
Less front contact patch by increasing RF caster and/or camber.
...

In preparation to start designing the 84 pitch pinion trees, I bought a few extra "oval racer sized" sets and put them in our web store.
...

Lightweight single arm center shock mounts are now available.

McPappy Racing Pinion Trees

This functional piece of art was designed to last a lifetime. Made with the highest quality materials. Real 4mm thick...

Contact me. I've got some extras I can sell you.

I don't have one, but most manufacturers drill .079" to accommodate a .078" hingepin. So far, the .079" fits the best on most front ends. What does your current hingepin caliper at?

These are hardened tool steel hingepins, precision ground, sold in your choice of diameter. Shaft diameter tolerance is a very consistent and precise +0.0003". They've been hardened with a molten...

New Spring Steel T-plate options are now available!
The spring steel material is now available in 3 choices:


0.025" thick
0.032" thick (original)
0.035" thick

The COT bumper is best if you are a new driver or racing with lower skilled drivers because of 2 reasons. #1, the shallow length gives you room to run a foam bumper. It's also made of 2.5mm carbon...

Great to have you with racing with us Rich!

Personally, I haven't done any testing with that yet.

Yeah, if you don't space up the left caster block, the car will be very aggressive due to the low front roll center.

Welcome to the new McPappy Racing Forum!

There are lots of McPappy racers spread out over the country and Canada, so one of the ways that we can enhance communication is our own discussion...
