Apex.
I have a question from one of the racers down at our local track that is running VTA and he is wanting to get into the racing with us.....He wants to know if he can run the A123 batteries he has or if he has to run the 2s lipo combo.....I told him what the rules said but also that I would find out....Have you guys tested these cells for competition in this class?

Thanks,

I realized I forgot to mention carpet. I've had a bunch of suggestion for Asphalt come summer.

We are right now. Knowing full well what we're doing isn't in the rules so for a sanctioned race. We club race.

I took the new Black and Decker VPX batteries, two sets of them at 12 bucks a pair, and made a 4 cell pack so it's still 6Volts but at 2200mahs.

With a brushed stock motor I'm not any faster on the straightaway but have more punch in the infield than NiMh. Not a huge difference but a difference to the tune of about a .4 seconds per lap.

We are also currently running one TA car with a silver can Tamiya motor and A123's, 2200mah. The car has great punch in the infield almost as much as 21.5 but the straight is slower. We are still in the testing phase with the A123 and silver can combo and haven't geared it to get exceptionally hot yet. That's the next test.

Essentially the point of the testing was to find out if a racer could have a battery that they could charge in 12 minutes, just leave it in, never take it out and still be competitive. So far the answer is yes.

I fully understand a silver can motor will never be sanctioned for USVTA, ever.

It's pretty clear the class is heading to 21.5 LiPo for all.

A good method with jack, is to clean your tires, apply the jack 20-30 min then wipe, let stand 5-10 min. Also use a terry cloth towel to wipe the tires with, you need something to get down in the grooves of the tire. We usually dope all the rear, and 3/4 of the front.

I tried this, it worked well, but went away quickly. I think my car was too stiff still. I had no droop in the car front or back. I hadn't even checked that.

So...

I backed out the setscrew in the control arms and now have droop. A little more in the back at the moment. I need to get it near a droop gauge and actually measure it so I can take notes on what works and what doesn't. I'd say from line of sight its about a quarter inch to 3/16 of an inch past flat now. The front is about a 1/8 to 3/16 inch past flat. I'm hoping this will allow better weight transfer in the corners and stop the car from hooking so bad as it slows down. I've got no drift at all. I did have to re adjust the ride height as the droop increased as the springs became completely unloaded.

As it stands, my rough settings:

front droop 1/8"
rear droop 3/16"
rear toe 2.5%
front toe 0%
camber 1% front and rear
caster 0% (at least it appears to be flat)
Ride height is around 1/4 to 3/16 inch
front control arms are long and parallel
rear control arms are long and slightly larger on the outside
spring weight - unknown

The track normally has two short straights, one long straight and a technical section.

A123 batteries are NOT legal in ROAR or USVTA racing. They are not on the plate for testing at the moment, so nobody should be holding their breath for legalization for these packs.

Exclamation HUGE News! USVTA at the Snowbirds!!

I’m thrilled finally be able to announce a union between the Snowbird Nationals and the United States Vintage Trans Am Racing Association. In less than a year, the USVTA has been leading the charge to help bring one of the fastest growing single classes in all of R/C car racing to club tracks around the country. To this point, the support and feedback has been outstanding, and this news should add to the excitement.

The addition of the USVTA class at the 2009 Snowbird Nationals will showcase one of the most exciting and entertaining classes I have participated in through my 25-years of racing R/C cars. With a decline in all R/C racing in recent years, racing needs a big shot of fun and excitement—and this is the perfect class. Much more reasonable speed, lower costs, realistic and exciting looking bodies, wheels and tires, less traction and wheel-to-wheel action drive this class. It IS the next big thing.

There will be at least 2 representatives from the USVTA in attendance to assist with tech, Concours and help with any questions or concerns that may arise. We’re all very excited to see Vintage Trans Am begin it’s relationship with the 2009 Snowbird Nationals, and we look forward to a fantastic event in February.

So get your Concours done up for the end of January, and get ready for some fantastic T/A action at the 2009 'Birds!
