Default Next Gen Touring Cars - Will they be designed for Lipo?

Im just wondering all your thoughts on this..... Any one seen any prototypes?

Im using a antique of a Yok-SD now and am in the market for a new Car....

Something tells me to wait till 2009 cars are out...

What you think?

I would say not exclusively but but maybe a 3rd chassis option(rubber,foam,lipo). The rest of the world still has not jumped on board.

I don't see why all the companies releasing Lipo batteries don't add weight inside the case to make them similar in weight to the current batteries so cars don't need to be redesigned and everyone doesn't have to go out and buy new cars if Lipo's become the standard. I believe some companies have done this with their Lipo batts, all of them should.

I agree with you there. Maxamps is the only company that I know that makes a 2S 14oz lipo.

Yes I too Agree also but still 3 factors..

1- Size adding wt to inside hard case will increase size so those may yet fit even less cars.

2- Currently we are not sure weather ballance is best with lipos with wt added to top,side or below packs all cars react diffrent from current designs and wt ballance.

3- Say you add 220 grams to a lipo to make up to wt of a std battery, What's to say thats good for brand X Chassie which is right at wt limit. Where Brand Y Chassie is already heavy and fully loaded Lipo with wt added will make that car heavy again.

Seems there will be a needed guide line for lipos and that needs to become standard for time to come . Then chassie companys car make a car to take lipos correctly.

Just my thoughts...

Because it's silly, and this is a better idea:

One nice thing about adding your own weight is you can pick where it goes, and maybe do a better job with ballast. There's enough weighting solutions now that it's not really hard to do. You can also hang the weight way out to the right side and get a little more leverage, which makes balancing easier.

As for designing cars around LiPo, that might be tough considering many car designers are in areas where 5 cell has become the norm.

It will never happen. Not all RC's need to add weight, in fact racing is a small part of RC and bashers in most cases welcome the lighter packs. Look at the new LiPo's coming out and look at how many run the new Traxxas connector and that will lead you to basis of my point.

One of the best features of lipo is reduced weight. Why change to a lipo if you want it to be like a NiMH?

I'm going to have 2 chassis made that will be spefic for lipos, but not for the hard cased lipos though. I could make some changes that would allow the hard cased lipos to be used.

This type of pack is already available and on the market. It is the same size and weight as a NiMH.

I run an Xray T2 with an Orion 3600 and 4800 lipo, I added the weight to the outer side of the lipo and didn't have to change anything with my setup, I couldn't even tell the difference between lipo and nimh, handling wise I mean.

Hallelujah! Well, except for unsprung weight concerns.

It continues to amaze me that so many RC people think you make a racing car faster and better handling by adding weight. Incredible. Hope you don't have any carbon fibre or aluminum on your car, that stuff will really slow ya down.

And if your concern is new cars & batteries, then run the old ones. I've ran a 14 year old car recently, had a blast, plan to do it some more. Wish I could revive some 1400s for it to really relive my mispent youth. Am going to update to new tires though!

Change the rules to reflect LiPO's

Lower the min weight!
Put a max on capacity! 4800mah should be enough, but I would perfer lower.

With a max capacity rule as the technology gets better with LiPO, the battery packs will start thinning down to the thickness of the Orion Carbon packs or smaller. It won't end the battery war, but it should help remove the chase for the most amps that can be drawn in 5-min.
