Running 9s A123 is about 22 volts under a moderate load. ( 30 volts No load)
2000KV= 32000 RPM or 44000
1600KV= 25000 RPM or 35000
That said, I don't have a controller that will let me run 9s A123's I am secretly hoping that MMM will be tested to that level by some daring individual. For 6S I think the 2000KV would be better and for 9S I like the 1600KV.
#$%^&* I am so confused....
Whats more effient, The Mega or the Medusa?

im also a bit stuck. ill be running 6 or 7s a123 (hopefully in 1p setup, is this enough for these huge motors? no one has been able to tell me this yet. having just over 500g of batteries is fine... having over 1kg is not.
im looking for something to run for 6+ minutes racing. which is why i thought going a higher voltage and gearing down = more efficiency.
on a scale of 1-100 in efficiency, what are the motors In YOUR opinion.
eg: neu 90
medusa 80
feigao 60
etc. just make up some numbers!
thanks guys for your help,
