I have done it on tire sets, and not done it on others. Didn't notice a difference at these speeds.

Maybe, have to wait and see.

Thx.
The HPI Vintage wheels come with a hole in them already.

My son's car is done. The paint came out fairly nice. I needed to be a little more patient with the hood and trunk racing stripes. We'll be testing tonight, time permitting. It will be good to at least have one of these ready to roll as they are identical except for paint. I'm still waiting on spacers for the narrow control arms, cutting my body and stickerizing it to my taste. Mine could be ready this evening, but not until after the initial test. I'll probably be working on it during F1 qualifying in China, like 1 AM Central.

I'm hoping to take a good look at shock angle, springs, oil weight, toe and camber. If all goes well in setup, we might actually be able let him race his on Sunday. I'll try and get some pics of him and his car while I'm at it. If anyone has a generic list of setup ideas for their cars, pass it along. This will be a carpet car, 10" wheelbase, low center of gravity chassis.

sorry this info is alittle late but we had an great time last weekend


THE EAST COAST TRANS -AM SHOOTOUT

“The Track” of Gaithersburg , MD has been the site of some intense US Vintage Trans Am (USVTA) R/C racing ever since the class debuted there in December , 2007. Over the spring/summer of ‘08, “The Track” did much of the testing and verification for the USVTA 21.5/lipo “spec” power option. Monthly Trans Am Enduros have added to the fun.

Things stepped up a notch on October 11, 2008 when “The Track” hosted “The East Coast Trams Am Shootout”. While attendance was a little lighter than expected, (don't you just love this economy?), racers did represent states from New York to the Carolinas.

Prior to the start of racing , a concours judging was held. Chris Green got top concours honors with an outstanding , realistic job on a Pegasus Mustang.

The week prior to “The Shootout” the track crew put down a new track layout. This was an “open” track, designed to enhance the side-by-side running that has become a hallmark of USVTA racing . And there was some racin’. After three rounds of 5 minute qualifiers, Robbie Dodge emerged as Top Qualifier. Close behind were Scooby Horton, and Arv Nano.

What can you say ? You just knew a 12 car, 8 minute, A-main, was going to be something to see. “Ya had to be there”. When the dust (and Lexan) settled, Robbie Dodge won with Scooby in second and Andy David running third. “Young Guns” Randy Bernard and Jon Isaac took the B and C mains respectively.

The first “East Cast Trans Am Shootout” is in the books. Those who attended enjoyed good racing and good fellowship. Hopefully , the “EAST COAST TRANS AM SHOOTOUT” will become an annual affair, marking the fall kick off for the indoor USVTA season, with the “USVTA Nationals” serving as the spring finale.

We ended up on the oval tonight for testing. No choice there, that's the Friday class. Testing went well! We sauced the tires, let them dry, did the burn out station then hit the track. The car for some reason seemed to get a little faster after about 10 laps. The new kit loosening up I guess. From what I can see, the car hooks up well in the straights, has too much steering at low speed and may need heavier oil and springs in the front as it still hooks ar higher corner speed. It still needs more testing with just simple tweaks in gearing with no physical parts changes. Practice without messing with parts swapping just to get used to the feel is needed badly. A certain 10 year old got a little impatient while dad was in the shop buying parts, He was "heating up his tires" like the real pros do. He lost control and cracked the chin spoiler and drivers side valance nicely. Time to "Goop" it up. We'll need to see these cars running against others on the road coarse to really get a real comparision, but he ran the car for about 12 minutes on 1 pack before I was called back to work. The car and the driver looked good.

You might try wiping the tires down completely after letting the sauce dry on the tires, before heading to the track. I have found that most tire sauces (especially Jack the Gripper) are really greasy on rubber tires unless they are wiped down. Burnouts in Paragon-soaked carpet usually does nothing for the tires but make them worse.

Give it a shot next time, and I'd bet that your first 10 laps are a bit less death-defying.

Default Front Diff Setup Thoughts

I've been away from racing since last winter and I noticed a lot of rubber tire setups include running a fully locked spool front diff. X-ray even has some fancy constant velocity half shafts to keep the chatter down when using sticky tires.

Last year I found my T2 '007 in TC trim ran well with a front one way and direct drive center layshaft. Given the grip is entirely different with these vintage tires what have you guys tried as far as driveline setups?

In the Tamiya TC class I was running into some folks with the one way on the layshaft and a regular diff up front. At lease with the open TC chassis we have lots of options to try out.

Just FYI, I went to Ihobby in Chicago and highly recommend it. I talked at length with the tech. representatives from a lot of companies and got the inside scoop that you don't read in magazines. I encouraged Tekin to present the 21.5 to the VTA rules team since the guy spent 45 min. with me explaining the ins and outs of brushless motors. Very impressive.

Not to speak for Doug, but I dont think you are going to see another 21.5 legal until ROAR produces a list of approved motors. Its nothing against Tekin either. They are a fine company with an excellent product, but if you want to support them then I suggest using the RS or RS pro and then getting a legal motor. Novak for 21.5. If you want to run 4cell then the Tekin motor might be legal, but I would have to check before I coud say for sure.

yes, the tekin 17.5 is a ROAR legal motor.

Unfortunately, snoopy is right - there is no such thing as an "ROAR-approved" 21.5...so until there is, only the novak is legal in USVTA

Trust me, I'd much rather run the tekin - but rules are rules...so I run my tekin - but its the 17.5 and with 4cell

The E10 is not the greatest. You would be better off buying a used TC3 or TC4 cheap. I am using a TC4 in the VTA class.
