I'd go 4s with the 5400 or 6800 for the fastest speed competition :). Actually, I could even make a 4s pack with the 2100HV cells I have laying around (for my 18t).

Quark 33a is better than mamba 25 i believe it does more amps or something (i think).

i would try that.....

Well I sent it in today. I'll see what happens.
Can anyone think of a reason why they won't warranty it? I don't think I voided the warranty in any way.
Thanks.

I hope you did not. Almost 9200rpms at 12.6V. This is unheard of.

Remember, though, high numbers are not ALWAYS good.

WOW! One week turn around from Quark! Got my new one in the mail today. Hope things go better with this one.

Thats what i call service! Good to hear!
