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.

jzemaxx,

I run the same motor in my MBX5T truggy and with 8S 3200mAh 25C packs (2 4S packs) I constantly get 30 minutes and my packs have over 100 cycles on them. I did a few 45+ minute runs, but I got bored after 30 minutes. My truggy is geared for 36mph (rounded out) without tire ballooning added (as always using BrianG's awesome speed calculator). I still haven't tried my Enerlands and you can go as high as 3700mAh without adding much weight. With the new 30C and 40C packs, I don't see a problem with a efficient HV set up going 45 minutes straight.

23 minutes? That's it? That seems awfully low for the battery specs.

You need more voltage for that motor, running 4 or 5s I'm pretty sure would be more efficient than swapping motors and running 6s...

These Neu motors I think need more, and like a little extra voltage... imo, from personal experience. ~24,000rpm what you are running now is just not ideal at all for that motor, you should be up in the 32,000+rpm range, I'm pretty sure 40,000rpm is the sweet spot for Neu's.
