How much more run time do we need? We race for 8 minutes. I don't see this being a good thing. Sanyo should make a good cell first, then increase capacity if need be.

look at offroad, they still only run 4-5 minutes (ROAR - IFMAR)same as they did 20 years ago when 1200's were the only game in town. the new batteries with higher milliamp ratings have increased the average voltage over the 4-5 minute runs. after the 2000's came out, i never dumped again. today in offroad some guys do 2-3 warmup laps prior to their heat and then run 5 min....with no problems
wouldn't be nice if you could do that with a 12th scale?
when the 2000's came out everyone jumped for joy......since 2400's, 3000's, 3300's they have been saying what you are saying now. to be honest so did i, until i got back into 12th racing in 2002
as for sanyo cells, 3000HV's were very good and could take high charge rates. i had i never had the problems that my friend had with his panasonic 3000SMH & 3000UMH. the 1st gen panasonic lite blue 3000nimh bats were junk
GP's first cells weren't a smashing success and the Sanyo 3300's were better..... until GP's 2nd gen cells. their new 3rd gens yellow/green are the best.
i am sure GP is ready to match or exceed the new sanyo cell in all areas.
the new panasonic 3600 haven't panned out in tests, they don't even produce numbers that the current GP's have.
the BAT WAR is on!

Hey guys! I had my first 1/12th scale race yesterday and I took second!
I am loving my rev3! I think I am going to update to a Rev 4 soon!
Thanks Ray for your help.
It was kewl.. I kept getting faster and faster and I ran a full lap faster in my main than I did in my heats!

It was lots of fun!
Then a friend let me drive his XXX-S after the races and I loved that too!!!
All my offroad stuff is now for sale(which is only a BK2 as my MFE seems to be sold) and I will be on onroad junkie now...
lol

Well James and i just completed our first round for the season although it was actually my second. The swing is sound but the putting and chipping are terrible!!!!
I ran my new Rev.4 yesterday at RSJ and with some tips from Jucha regarding the center shock and the addition of some o-rings to take slop out of the steering linkage it was the most awesome 12th scale car i have run yet!
Boy do i wish i had this car a month ago. 
On the subject of batteries the biggest issue to me has been the cycle longevity of the cells. 5-10 cycles (charge/discharge) before the loss of runtime is unacceptable
and GP is the first company that has made the NiMh cell to get past this barrier.
The Sanyo and Panasonic cells lost runtime within this time frame it seemed to me and thus neccessitated constant replacement with new packs especially if you were going to run modified 12th scale. On-road modified racing uses runtime and permanently losing more than 15-20 sec. of runtime is major in my opinion.
:
It's like taking a 410 pack out of the car and running a 390 or 380 pack in it's place and i don't think that is going to cut it in todays racing. With the longevity and performance (runtime, voltage, i.r.) of the GP cells even 12th mod is enjoying a steady comeback which is great for the sport and industry.
If ROAR and IFMAR are going to allow the Sanyo cell than hopefully it will have the robustness and longevity that the GP cells have displayed over the past 1.5yrs.
This quality is the major reason in my opinion behind the resurgence of electric racing, especially 12th scale. The true battery war to me seems to be when you have to buy 10packs throughout the indoor carpet season (Sept.-March) in order to stay competitive because the packs deminish so quickly.
GP along with a slew of great matchers such as SMC, Hurricane and others have given us a cost effective and thus more enjoyable way to race and i hope that other battery manufactuers aren't allowed to mess this up with lower quality cells that promise better performance for the initial 5-10 charges and then die off rather drastically.
Now if i can get the chipping and putting good enough to compete with Paul Lemieux then my golfing summer will be great!
Barry how much would you charge me for a few quick lessons?

Hey Dave, did you run at NIROCC? I'm almost positive you did...
I hope you're right about 1/12th scale growing again, I just got back into RC after leaving it when NIROCC shut down. I'm having fun with TCs but I would love to get back to 1/12th scale. Now we just need someone locally to run it regularly so people will be willing to make the investment in a 1/12th scale car.

I'm struggling to understand how you are dumping in 1/12th scale mod
I'm not a top contender at the UK National level, but compete in the series. Running anything from a 12x2 down to a 10x1 I don't dump. Sure you go soft towards the end if you jam in the beginning, but part of the craft of 1/12th scale is to time the drive to suit the demands of the race.
Perhaps you are running outdoors and require more "go".. ?
In the UK we race indoors on carpet and typically my MMPR is between 36 (10x1) to 40 (12x2). If you are trying to pull 45+ then duration may be aproblem, but them you aren't getting best efficiancy from your motors. They sould also realistically be set between 12-18 degrees advance, more than that then they are being overrevved.
My 1p's worth, HTH

I would agree-I ran my same two packs at 04 Nats two weeks ago that I ran at the 03 US Indoor Champs. If taken care of-these cells perform at a very high level and for a long time.

One more update..
I changed my servo from being angled to being flat on the chassis and man... it made a huge difference!
The car is much less twitchy and more consistent...

running with a rec-pk and 11x2 with 5 deg adv with soft springs, i don't dump.
if i go to a 10X2 with same settings and take it easier on the throttle i still don't dump
when i have tried 9's it is too close for comfort
DARNOLD
i started with the second gen GPs and haven't had the luck you have when it comes to the runtime not fading.
i got 6 pks of the new GPs yel/green cells from Fukuyama and they were killer and consistent in the runtime department.
quality is good but consistency between cells is poor. when i see cells rated from 390 sec to 435 sec in stores. then see some drivers with 450+ sec freak cells and these were all from the same matcher.
Avg Voltage...don't even want to go there
