Trick photography.
That saves 30.00 on lipo bags.
I didnt trust lipo bags any way.
Every time I seen one used the dang battery blew up.

I did. I bought 4 of them for more info visit: http://forums.radiocontrolzone.com/s...=219459&page=4 it speaks for itself

They are good if you don't care about the fact that they lie about the capacity and there is a variation in the voltage (look at the discharge curves I posted in the thread)...

i think Mr. Jolly was refering to cells like the Epic reshrunk IB's they have, LRPs (Vteck?) cells over in europe, Yokomos cells, Reedy...etc.etc.

from Yokomo's site: "Although the same Intellect IB4200, make no mistake, the "X4200IB" is a special product, as only top-graded cells selected during the production process are allowed to wear the Yokomo brand name."

do they have a deal with IB to get the best?

Yokamo were the best I ever owned.
I think they were Reedy zappers?
They lasted longer than any other packs I ever owned.
When the 3300's first came out.

This means that the average Joe who wants to get into racing will have to shell out $100-150 per battery just to keep up (lets say 2-3 min. for a race weekend) and this will discourage racing. I guarentee you that there will be an advantage to running some sort of Lipos over others, and instead of having prices in the $50-60 range, buying a new pack will be $150 - battery technology will still change, and everyone will be forced to update their stuff just as regularly as they do now, albeit at a higher price per technology change (again, look at your Nimh set-up, IB4200WC right?).

Another point I want to address is safety. Do you really want to be running 10+ trucks on a track with lipos in them all day long? Lets just say you get 8 heats in per day, thats 80 cycles where a lipo could be punctured, burst etc. - 160 cycles per weekend. At that rate, some batteries are bound to fail. It happens even with Nimh cells. But with a lipo, the failure is going to cause a much bigger problem. Lets say 1 lipo fails in 10,000 cycles (I'm being very generous to lipos here) - that's going to be one hell of an explosion, and we now have a racer down both a battery and a truck, not to mention a possible story on the evening news about how a kid got killed by his R/C car (you may laugh now, but it won't be funny if it happens!)

I just felt like I had to chip in my $.02 as I sell both battery technologies, and I see where you are both coming from - as I see it, with the current technology that is available, ROAR made the right decision on this.

If you are saying that you really need to improve your driving i have drivers in stock a club level regulary beat guys with 3700 3300 and son it all about practice and peperation.

When I was running stock 27, 3700 seemed to be as good as it gets.
The higher MAH didnt help at all. When I went to 3800 it was ok with 19 turn but I didnt like'm with stock. Same with 4200 I guess the peak lasted longer but the punch of the 3700's wasnt there.
I think the higher MAH's are more targeted for mod racing.

Though I usually don't have a lot of faith in those who have a product to push, i tend to believe Danny. He is saying what I always felt would happen: the cells would be improved for racing, without concern for durability, like NIMH. Once racers get a hold of these cells, they will start doing stupid stuff to get them to run faster. Racing is racing, only the prices change

I just think a lot of people are comfortable with the current scenario. You know what you are getting despite the drawbacks. Lipo is an unknown, which tends to make people frustrated. If you like lipo, keep on trucking. Honestly, most people going to big events don't care to change. Change = $$$

Be careful, I've heard through the RC grapevine your PC may suffer the ultimate wrath from the "virus gods" if you irritate the wrong people.

Default Racing with Li-Po

I`m now not...
*removing the battery after each heat
*discharging the same one ($35<>$100`s)
*installing same battery on a conditioner( $75<>$100)
*charging another battery
*reinstalling fresh charged battery for next heat

How this is bad for "me" or our "sport" I
cannot understand !

would seem the Li-po makes it way easier for others new to this sport to have fun....


But nooooo .....

We must stay with the same battery`s we have now ......

and
After all these years we have embrace new battery`s ....

Every new cell has been used and push aside by a newer and better one....


So why now should this change ?

I can`t believe the politic`s involved in this sport.....

After all the rants , you are most probably not interested in these results but here goes.

I have been cycling the new cells from GP and the results are as follows:

GP4300H-MPV similar runtime to IB4200WC
voltages the same if not slightly better than IB4200WC
internal resistance much the same

GP4600 runtime - up to 40 secs more than IB4200WC
Voltages - approx 0.005v less per cell than IB4200WC
Interenal resistance - only maybe .1 more than IB420WC

It would seem that possibly GP have produced a cell that can compete with the latest IB4200WC cells.

That's interesting. When I spoke to someone from GP at Nyremeberg's show he told me that voltage is worst compard to their 4300 only capacity is better. So he recommend those batteries for 1/12 and 4300 for 1/10
