Default apples to apples

Rushing to create equivalents as we given new technology has always been a problem. I experienced this when brushless was new to the hobby...the club I raced at had 13.5 running in 1/12 stock..unless you had the "new stuff" you were just trying to keep out of the way. Later on ROAR announced 17.5 as the equivalent...that worked better and everyone in the class now has a reasonable chance to "compete".
The 21.5 Lipo spec is just a repeat of trying to fit "new stuff" into a class.
I would expect that ROAR has more resources and done more testing than anyone. I'm satisfied with ROAR's eqivalence spec of 17.5 and 27T..both using 4 cells. The fact that ROAR does not endorse 21.5 Lipo/2S as an equivalent to 27T and 17.5 4 cell should be reason enough to not paint outside the lines. When a 4 cell replacement comes available, I'll run 'em...untill then I can wait.
-To be clear... I'm not "anti-lipo" I'm for class parity.
Yes, I race TA...It's easily my favorite class. I don't need blinding speed to have a fun race and I don't mind working on my car. (I'm running 4 cell 17.5) I just want to put a race car down that's "apples to apples" with my competition. Maybe you guys just need a category 2 class to appease the Lipo folks...It'd be cool to run a Vintage Vette or Porsche!

With the positive results on limited testing we are seeing on single cell LiPo and 13.5 compared to 4 cell 17.5/27t in 12th scale we are persuing testing in this direction.

Adding a single cell lipo option may allow those who are buying new or wanting to not maintain batteries a option that will not make the cars move at a faster speed and continue to allow those moving old 12th gear, stock brushed motors, and stock sedan 17.5's the ability to still compete on a level playing field.

anyone who trys this combo please send or post feedback.

How's racing in Minnesota these days?

You get more 21.5 requests and split the cars at this point or sticking to the no 21.5s?

I thought the comment about 17.5s and single cell lipos was interesting. I wouldn't mind something like that if they can make a 1S that is viable for this class. I still can't see going back to 4 cell.

Good luck and have fun racing.

The minnesota clubs that are running only 4 cell versions ( not the MMR Club Spec) are doing very well ( Largest race class on the track). 25 VTA's on race days 30 total racers running in the group no 21.5/lipo.

The fastest cars are running the MMR Spec on FDR. So the potential even in what is running for the groups to go faster is there. The racing has been very close through the ranks with some still figuring out how to hold onto the car and getting a setup under there feet.
Going faster is a bad option the field will thin. We have seen some clubs add growth going faster and many lose some racers as the cars get faster a very hard balance. In the past 20 years of racing in the industry it is almost always the same cycle.

VTA in general is doing really well here too. Because locally we all started with 21.5 and are happy with it we'll probably stay there, its still the second biggest class at the moment. I think there are another 10 or more hold outs waiting for the 21.5 Havok to come out to venture into both brushless and lipo at the same time. I've been getting my lipos through Ultraline in MN. The Yeah! racing 3200s are 20C and are perfect. I think in the end when C rating shakes down, that C rating and motor will be severely restricted for us to run one motor and a set C rating to generate parity. I do think its very cool when the whole field for a heat or main finishes within a lap or two of each other with 3 or more competing for the lead all through the race.

Single cell lipo so far has looked very promising. Seems just a hair slower then 4 cell about 2 tenths off pace. Car handles great durability and drivability stays high. Motor options remain tha same.

Looking to test 13.5 single cell compared to 17.5 4 cell nimmh. This may be the ticket to keep speeds in check and options open and seems to be doing very well in 12th scale testing.

With another great winter season in and done. We have quite a few things on the table for Fall 09.

Fall 09 is going to be single cell lipo or 3 cell Nimmh. Same motor options no FDR.

We strongly recommend a booster from Novak or a receiver pack. Most electronics are not happy at the lower voltage.

Summer Testing has shown single cell 17.5 to work excellent as a power source for the club racer. Keeps speeds were they néed to be requiring the driver to work the line to become faster and makes the choice to rubb even more interessting. Laptimes are very close to 4 cell depending on track. We have seen as little as a few 1/10s and as much as 3/4 a second spread between 3.7 and 4.8 volt cars.

09 - 2010 should be very exciting and we look forward to another growing year.

One of our test mules. Top runner and the racing has gotten even closer then we had with 4 cells you can actually use a draft pass on a large track....

What we know about speed controls and 3.7 v.

First almost All of the speedos work better with a boosterS and servos are definatly faster.... We have run te novak and the tq boosters. Tq fits better but novak has the cool lights.

Speedos we know to work on 3.7.

Gtb
gtx
some Lrp sphere's. Some will only work for 2 laps some 2 minutes some 8 minutes.
Spektrum works fine.
Futaba fm 75mhz work fine
Jr fm work fine

Require booster or rec pack
LRP spx, Sxx, most spheres
Tekin rs, rs pro,

gearing has been within 1 tooth of 4 cell same combo on most tracks.

i have been running under the MMR VTA spec for a year and it has been a blast. i am a ok driver, so the throttle finger and the steering hand sometimes do not get along great, but i have been able to run with the "fast guys". the cars are so easy to drive. i was a test mule this summer for 1s lipo in the vta and just about everybody else was running 4 cells all on 17.5. it was a tic or two(.2 to .6) but i would get done racing for the night and hand my radio to somebody watching and they could drive the car. i run 1/12 scale for a fast class 7.5 1s lipo and there is no way i would hand my radio to somebody that does not race. we just started the rule package for the winter of 3.7(1s lipo) or 3.6(3 cell nhim) had one big carpet and one small carpet and this is going to be really fun(the rubbing and the set up for the pass is awsome)

i love to go fast, but more people can race slower

Yes and that old snake has seen it share of the lime light..... Makes a incredilble vta car. With our current rule package parts support needed is almost zero... Maintain becomes bearings and that's about it.
