I just got some insider info-expect 52,925's by Christmas. At 30A, runtime should be in the six hour range. Matched six cell will run about $16,000, and available in limited quantities.

Looks like Orion has their version now, too...also in stick pack form: http://www.teamorion.com/news.asp?id=450

The orion site clearly states that the cells are "nearly" as good voltage and IR as 3300 and 3700. So, for serious racers, they are probably not better.
In response to T Thomas: Maybe the weight restrictions should be reduced. More and more cars are comming in under weight due to the advancement of manufacturing techniques and materials.... It was just a though.

Another suggestion to make the battery war worthwhile - longer races!
when I started racing a lot of mod events were only 4 minutes... then they went to 5 minutes as battery (and motor) technology improved... maybe its time for 6 or even 7 minute races ??
One of the reasons I loved running brushless was because of the longer runtimes
I have also heard of a few clubs here in australia trialing 6 minute stock races

The "R" at the end denotes 'rainbow' shrink as used only by Trinity (USA) and Orion (Europe). It does not mean race. The lack of either the 'R' or 'C' means that it is the industrial version of the battery. Both the GP3300 and GP3700 have an industrial version which are GP330SCH and GP370SCH, respectively. They come in plain green shrink and they are completely different cells than the R/C cells.
i always thought GP just made different wraps for different customers?

japan races 8mins using their 23turn stock motors. personally i still prefer 5mins of racing

Motor temperature could be a problem thou. But then i wouldn't be suprised to see heatsinks like the much-more electric cooler, developed to be light enough to be used while racing in the next few years

i remember a discussion like this came up a while back when the 2400's were being used and the 3000's first hit the scene. there were two sides that came up, one side wanted longer races, the other wanted to keep the races at 5 min, but wanted to lift the 10T motor limit that roar was using for their races that year.
longer heats means a longer race day just gets longer and longer. sometimes club races don't finish until after midnight already as it is.
but then if you don't lengthen the race time, then faster motors can be run. the argument was that that would lead to higher costs (faster motors usually wear more, requiring more frquent maintenance and replacement, not to mention breakage of parts would be more extensive in a crash)
time will tell which is better i guess
