Hey Rob,
I run: XB808 - 1512/3D or 1512/1.5Y on 5s 4300 packs geared for 38-40mph. I easily get 15+ minute from that setup. No issues at all. Even with a conservative LVC setting I can probably get close to 20 based on the mah/minute usage I see. I never see usage more than 210-215mah/minute with either of those motors even on the big tracks. On a small track it drops to just under 200mah/minute in some cases.

I highly recommend the 5s racing setup. It just works better than 4s for me. Everything runs cooler and even with the low KV motors it still has plenty of power. With this setup and a pack swap at the 15-18 minute mark you would have no issues at all making 30 minutes.
