3S in a HPI Sprint 2 Flux?
Hello
I have a HPI Sprint 2 Flux that I've been driving with 2S for a while now. And recently I also bought a Firestorm Flux. And for the Firestorm HPI says its OK to use 3S lipo: "With up to 8 NiMH cells or a 3S LiPo (11.1v)".
And since the Firestorm and the Sprint 2 Flux uses the same motor and esc, does this mean its ok to use 3S in the Sprint as well?
Very thankful for any answer!
Best regards,

Why would anyone want more power? If you can give full throttle there is still room for more power!
After driving my Vorza with 6S at 60mph+ the Sprint 2 Flux seems very slow with its 30mph or so

The electronics could handle it but make sure your gearing is appropriate. I think your belts/pulleys may not be able to handle that power though, it's definitely worth a try if you're not racing and just bashing.

the flux esc & motor can handle 3S lipo, gearing is very critical and make sure you gear it properly.

So should I go higher or lower in the gearing? (Higher or lower top speed)

You can run 3s on sidewinder/hpi flux motiv with 5700, but your pinion has to be small.

I am pretty doubtful that it can handle 3s. The hpi webpage for the Sprint 2 Flux mentions being 2s-compatible, but not 3s. Compare this to the e-firestorm page which actually says 2 and 3s compatible (it has a 4800 kv motor).
Also, fyi, this car has a 5900 kv motor in it, not a 5700 kv. Given that both the e-firestorm and the Sprint 2 have the same Vapor ESC in it, it's likely a case of the ESC can handle 3s, but the 5900 kv motor in the Sprint cannot and will overheat.
Oddly, after pouring through the manual pdf, I don't see it spelled out anywhere what max voltage lipo this car can handle. My advice, if you want to absolutely be sure, is to email HPI and ask.

Just picked up a 3000mah 40c 3s skylipo today and dropped it in my 1 week old Sprint 2 Flux, that's bone stock. Ran it tonight with the grip tires and it flew. I didn't have my temp gun or gps, but temps were not so bad. Maybe 130s on the motor and esc. If I had to guess, it was in the 60's for speed!

Does HPI say it can run a 3S?
Why does no one know? Weird....
