My mistake - probably caused by excessive laughter at the time - it's Xpress not Express - web site is http://www.rc-xpress.com/html/all.html
Run your Sanyo's in it and enjoy - not everyone needs the latesty gear to have fun.
cheers

I dont know how many time I have to say this but I will be running IB4200's. Is it just me or is the average person in here realy this thick ?

Only one cell exploded at such a low current draw. All other cells exploded or vented above 50 amp draw. I did various charge and discharge rates to see what happens with the cells. So i didnt include that cell in my results as i thought it must have been faulty so used another to replace it in the results. Yes we brought in 100 of the Sanyos to do this test, but have about 3000 IB cells left for testing.
All cells exploded at 3c and 20c discharge continuous rates. Just to note the IB did vent not explode at the same control test IE: 6 amp charge 10 amp start, but noted that the IB didnt vent as early as the Sanyos. They vent more towards 60-65amp draw where as the Sanyo vented around the 55-60amp draw. This indicates that the cell manafacture is a stronger case and the vent system is set slightly higher in temp.
This is within design specs for the said cell.

PS. Now dont take this the wrony way, but Charles if you went to HarrisR/C website on the home page Tony introduces himself. So yer you werent looking hard enough, possibly not at all?? It sticks out like a bloody sore thumb ..... Perhaps you should re read all the websites that you have been looking at to see if you havent made any more errors??? This misinformation may have been posted in this thread?

One would expect a lower capacity cell to die at a lower discharge current. I thought the Vent opened at a particular Internal preasure. Not directly related to temperature ?.
It still doesnt explain why the IB4200's are exploding under normal race conditions.
Ok. Would you believe the Home page was the only page I didnt check. Pretty damm silly of me eh !. Yes, I did look. I looked at most of the pages. I just checked then and saw his name. Thankyou again.

Logical deduction would have meant that you could have determined who is who from the information on the websites and this thread.
And as for the Xpress car, believe what people tell you. The car has all the "bits" but is uncompetitive in todays racing.

As for the xpress. I would expect a car that is 5-7 years old should be less competative than the latest models. But at the time it was up their with the best. This was the same time the RC300's were up their with the best.
My comment was simply that it had all the Bells and Whistles. I made no comment on how competitive I thought it might be.
But surly it would still be very competative compared to the average cars available ?. I know the HPI Sprint 2 I bought handles like crap compared to the xpress.

Some interesting reading about the latest technology cells available today.

I will do some research on who Mike Swauger is.

Wow, Their are so many links with this Guy's name. He certainly was/is one of the top runners.
I can see why the spare parts are still available. Even though this chasis is 7 years old you can still buy them. Exactly the same one I have.
Price landed is Aus buying direct from the states does vary but some were around $400-450 AUD. A lot cheaper than I paid. But I did buy it at the shop at the track which does add a noticable amount to the price.

And I will say it again. It's starting to sound like a broken record but no-one wants to admit what I am saying.
I agree %100 that the IB4200's are by far the most competative cell on the track. I have also said I would be running IB cells.
How can I make this any clearer ?
It was not an attack directed at any specific Matchers EG, Feral batteries or Harrs R-C. Unlike your attack which was direct at me personaly. The differance is you used my name. I used no-ones name.

If you check out the signature for Cannon and Addicted you may be able to figure out which matcher is which

Mike is one of the current top Mugen drivers and placed in the top ten at the 200mm tc worlds last sep, So he was AND is still a top runner!

Glad to here that. Since he is still one of the Top guns that does explain why this model chasis is still available. Even after 7 years. It was probably one of the best ones available when I bought it. Which would explain why it was so expensive.
