I am trying for 20 min on a 5000mah battery

Not really. The only way to get more run time from the motor would be to:

1. Increase Efficieny (not easy as the Castle Motors are basically Neus)
2. Decrease kV (and therefore speed)
3. Go for a slightly smaller motor (but not too small, as it might not be man enough, and will cause heat buildup, and therefore decreased efficiency)

Only thing is, none of these is likely to be enough. According to your readings (270mAh per minute) a 5000mAh pack will get you 18 minutes and 30 seconds. That's assuming that the pack drains completely to 0mAh, which it won't.

I would go with some of the measures above, and a slightly larger battery (like a 5300mAh).
