1515 2Y on 6S???

[jzemaxx]

Thinking about trying this as a test. I am running now the MMM with a 1515 1Y (2200KV) on 3S 5000mah (10000K total) parallel. I am getting around 23mins with that setup and runs fairly cool. I am thinking about dropping down to the 1515 2Y (1100KV) and going 6S 5000mah. Would I gain anything from this swap? I am thinking I might gain some runtime and drop in heat......it will be geared for the same 36mph. I am trying to get as close to 30mins as possible without a swap, but weight is a major concern. Our races keep getting longer and the pro classes are minimum 30mins and I their is a 45min race coming up later this summer. I would like to keep it down to 1 stop and still have some breathing room.
