Tuning front tires.

November 28th, 2011

Quick tip:

If you do not glue the side wall of your front tires the front tire will feel very “edgy” as the sidewall grabs harder.  Not only does this make the front dig in more, but it can cause the tire to wear faster or even chunk on the outer edge.

Prior to truing your tires apply a bead of thin CA-glue along the side wall.  When you true the tire, radius the edge of the tire. This will leave a clean glue sidewall that will resist wear.  You can add CA to the sidewall as the tire wears or the CA chips off.

Radius the edge of the tire so that you have no vertical edge.  If you have to, radius the tire before gluing.

Using a high grit sanding file on the sidewall can polish the glued edge and take even more edge out of the tire.

 

Speedmerchant Rev 7 build

September 30th, 2011

This weekend I finally started assembling my Speedmerchant Rev 7, I’ll start posting pictures as this build progresses.  This car uses an inline (off set) battery configuration, keeping the weight down the centerline increases corner speed and makes the car more effecient.

When debuted at our club inline cars immediately put a lap (and more) on the traditional layout cars running.

The first thing I do with any carbon chassis is to sand and seal the edge of the carbon fiber.  This gives the edge a finished look, adding to the overall clean look of the car.  It also protects the edge from chipping, and to a point helps the car scrub less speed when it makes lateral contact with the carpet.

 

Additional: 11/2011

Car is finished and racing well.  I ran this car at the Timezone Grand Prix in November of 2011, in 17.5 stock it pretty much dominated the field.  Set an early TQ pace and crushed in the first two A-Mains.  It had ridiculous corner speed.

A race report and setup for this car can be found here:

ReVtech Motors!

July 28th, 2011

The design goals of Team Epic when developing and testing their new line of Revtech motors was to make a companion line to the D3 rather than a replacement. No motor design can be optimal for every track, battery and vehicle combination – but Team Epic says that their D3 line has achieved the goal of the most powerful brushless motor while delivering the brute low-end power at operating temperatures below the dreaded “melt down” zone.

 

The Revtech line features a wider power band for running 1-cell oval, 2wd short course and off-road trucks and buggies. Revtech motors feature a wide high rpm-based power band, new stator lamination design and material, more mechanical timing adjustment, new bigger and easier to use solder tabs, and new heavy-duty high temperature wire. The Revtech motors are available in winds from 4.5-9.5 modified and 10.5-21.5 ROAR Spec.

You should race 12scale.

April 15th, 2011

1/12 Racing is the purest and best form of carpet racing.

Simple, inexpensive, fast, and fun.

Touring car racing is the norm, these large lumbering four wheel drive cadillacs have all but driven the casual racer from on road racing.  Hundreds of adjustments, massive front to rear bias, rubber tires, and terrible looks to just baffle and drive away someone who is trying to get into racing.  Not to mention the basic cost, it’s no wonder turn out is low across the country.  It’s the cars themselves that are killing racing.

The 12scale is often overlooked as being a lot of voodoo.  It’s really not.  It comes down to two things; making sure the chassis is straight and untweaked, and having the right tire.  These are just one of the millions of things you have to deal with on a touring car, only simplified.

With a 1/12 car you  need to build it straight, make sure you are running the tires appropriate for the track, and make sure you maintain the tire.  You may not have the fastest car but you’ll have a stable driving platform that is suitable for learning how to drive and get faster.   Often times spring adjustment, camber, or rear shock adjustment is done once and not touched all season.

As I write this the most expensive 1/12 car is $250.  I can find similar cars used at the moment for $75-100.  Some with smoking deals, like servo or a battery.  Even if purchased new, you can find some inexpensive cars like the CRC for as low as $150….electronics are cheaper, motor and esc is the same, but added all up it is considerable savings.

2006 1/12 Worlds

The R/C Trim Hookup.

March 30th, 2011

This was my pit and scheme for the the 2011 ROAR Carpet Nationals.  I had to represent hard, and come in style.  What really set this scheme off is the fat R/C  Trim Vinyl on my pit board.  Pete was able to print a piece of vinyl that was exactly the same size as my HUDY 1/8 pit board, down to the millimeter.

The best part of this vinyl is it cleans up way easier than original surface, so with a quick wipe of motor spray the work area is clean and bright again.

Also tools slide along it really well, ride height adjusters, camber gauges, all have a much more positive feel on the surface of the board.

What you cannot see in the photo is the hash marks on the board making width changes to the car very easy.

@ ROAR Carpet Nationals.

March 22nd, 2011

ROAR Carpet Nationals are this week, being held March 23 – 28, 2011 at Timezone Raceway in La Center, Washington.  This is a sell out race and should be a great event and an excellent way to put the 2010/2011 carpet season away for the year.  I will be heading down with the Viper and RC-Trim team, check out www.rc-trim.com, and redrc.net for other updates and content from the track.  I will be posting photos and videos as I can from trackside.

I’ll be looking for pimp pits while I am there and getting what’s hot in proRC gear and relaying that info back to the site.

My biggest dilemma at the moment is pit towels; grey or orange?
