I've just started a Revo conversion using the Tekno kit. I am new again to RC(been about 15years) and will only be bashing (at least to start). So I'm looking for decent speed, long run times, and decent handling. No wheelies and no land speed records needed. Eventually I'd like to go to a track, but there are only 2 anywhere close to me. I will be locking the trans into second gear on the eRevo. I will be running a center diff with both mechanical brakes. (similar to Finnster's original conversion) and I plan on getting the MMM.

So I've been looking at these motors:
Medusa 60mm 1600kv on 5s
Medusa 60mm 2000kv on 4s
Feigao 8XL 2084kv on 4s
Feigao 9XL 1853kv on 4s

I've kinda been leaning towards the 1600kv Medusa, cuz it seems like theres a trend to go lower kv and higher voltage. My concern with the 1600kv is BrianG's calculator (awesome BTW!!!) says it will only be running 28,000 rpm on 5s and i think the Medusas are rated at 60k. Will i be losing a lot of efficiency and power running it at such a low RPM?

As far as batteries go, the more i read, the more confused i get. I understand the more volts I run, the more power i should get. And i thought the more mAH I had would give me longer run times. But now theres this 'C' rating which i cant get my head around. How does the C rating effect power, run time, etc and how do all three inter-relate and effect each other?

A couple of the batteries Ive been looking at are:
TrueRC 4S 8000mAh 10C
Polyquest 5S 4500mAh 30C
ZippyH 4S 5000mAh 20C
ZippyH 5S 5000mAh 20C

Thanks for any info and advice you can provide. Also, Im open to other suggestions. These are just what my inexperienced researching came up with.
