ok, yes thats true, i guess i just meant higher spec in general.. i used a 1.18 pack as an example..

I should have just said a high "spec" pack.

i still think the extra runtime will come in handy for me.

I guess I have mixed feelings on the another generation of batteries. For most classes 3300 MaH is plenty so there is no need to spend more on batteries, and they shouldn't have to if the power output of the new cells is the same.
For me, I would welcome more capacity for 12th scale and sometimes mod touring car with low winds. 8 minutes in mod 12th scale is still tough with 3300's. Even at the pro level they still dump. Watch the recent Cleveland video on nashrcracer.com. I'd rather see them race hard every lap and not have to hold back for fear of dumping.

take care
john

The nitro comment is very true. I see that as some of the popularity of nitro right now. A fast engine is a fast engine. There are faster ones being made but an rc car can only handle so much power...lol

I am thinking about getting into nitro offroad to get away from battery issues for atleast the summer months...so I can save up to get some new batts....lol

I think a lot of people are missing the point.

With our current racing formats (ie. 5 minute heats etc) the extra capacity batteries may not be helpful unless you of course you intended to over gear thus killing motors.

Properly geared Brushed motors can run extended time without overheating.

The point is... why are we still running 5 minute races???
The racing formats MUST develop along with technology.

i dont fully agree with the race format having to change, because in a few years it will be more like an endurance race than a sprint race.

3700s will help loads in 12th scale, i can never finish a race in 12th scale.

5 Minutes barely qualifies as a 'Sprint' race. 10 minutes does NOT qualify as 'endurance' racing.

We've been racing 6 minutes heats and mains at our local offroad track for a few months now. Even with just increase of a minute took some time and adjustments to get used to.

Default gp3300

hi guys,
gp3300 are just fine. at my club we once ran 7 min finals in super stock 19 turn and our cars were fine. i charged my cells at 7amps and at the end of the race still had about 5 min left. this was with 28 matched batteries. in modified just charge at a lower rate.

I believe that extending race times for most electric classes is going to put a lot more strain on our equipment than people realize.

Putting two five-minute runs on a motor or a set of tires is FAR different than running 10 minutes continuously... I can see maybe being able to get away with it in some offroad situations...but I believe touring car/onroad is where you will see problems arise faster...

I'm not saying that it cannot be done... I'm just saying that if we want to run more than five minutes we're going to have to change more than just going to bigger batteries

you could just put two heats into one. instead of two 5 min finals do one 7 min final.

The real issue is time. Most people have lives outside R/C and can't stick around for the extra 2 hours on race day to accomodate longer heats and mains. JMO

Mmmmh people if you calculate most actual good GP cells are already 3400-3600mAh only the lowest are 3300mAh. So I think you don't need to worry too much, difference won't be that big. There's already no dumping today and the motors can't take more power as of now. Low IR is what we need!

Longer race days will depend on how many heats you actually run. If you are used to 3 qualifiers and the mains, then yes. But if TC races here in the USA went from 5 minutes up to 8 minutes (like they are in Japan) then you could get away with only 2 qualifiers and the mains. Just a thought. Everything all depends on racer turnout of course...
