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.

I've tried racing 3s on the 1515 1y as well. I was probably geared a couple of mph's slower than you, but I was pretty happy with it, everything ran really cool after 15 mins. 15mins is the longest I've ran it like that, but I used ~6000mah out of 9800 total, which means 24-25min max.
When I use that motor on 4s 4900 the most runtime I will get from it is about 12mins. Most of the guys I race with are using about the amount of power as mine, sometimes more.
I used to race 5s 4900mah with the 1515 2.5d, and that would get between 16 and 18min racing.
I haven't done an actual race with 6s in it, but geared to the same speed as my 4 and 5s setups, I would only expect 22 or 23 min.
From all the setups I've used and all the setups I've raced against I just don't see much more than about 25mins possible in a truggy, on 6s 5000, in a race, with a good driver, unless your car is somehow super light or it's geared to be super slow. For bashing sure I could do 30mins plus, but I've always found racing runtime is always less.
