30 Minute Main?

[Sower]

Ok - is anybody making a 30 minute main on two batteries? If so, tell me what your setup is and what buggy you're running. Thanks!

OK I know something
I have Truggy XT8 With MMM 2200KV combo geared to 42mph on tight track 5000mah battery is barely enough for 15min Truggy weight is ~4410g with Zippy-H 4S1p battery, so if you have heavy finger it can be not enough for 15min pit stop.
Second setup what I built is Xray XB808 with MMM 2650KV combo. Car was geared to 38-40Mph same tight track experinced driver not heavy finger. Weight was 3400g with 4900mah 4S1P Rhino battery. With easy do 15min pit stop.
Hevy finger makes Huge Difference. With 10min of driving with nitro stile my truggy can consume 4200mah. With restrained style finger like in on-road truggy consume 3100mah.
Sorry my englis is bad, but I hope that it will give you some picture.

Great info - thanks! Does anyone else have any comparisons? I just bought the new XB808 and want to make sure I get two batteries that will make a 30 minute main and still fit under the body.

Here is conversion xb808 what I made for this guy

Used narrow battery from HobbiCity. Idea was to put battery maximum close to ground and close to the center and ESC too

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.

Nice - thanks. So, what are the packs you're using and what are the dims on them? Especially the height. That's been my big question. I don't want to get a pack that's too tall to fit the body on

Using a mix of NeuEnergy 4300 5s, Ployquest 4350 5s, Flightpower 4350 5s, and PloyRC 4350 5s.

All of them seem to be good. All built with the same base cells I believe. Pack size is about 165 x 46 x 39. Some minor varience in the thickness (39mm dimension) from brand to brand but all pretty close. I have a couple mm of spacers under my front body post for a little extra height in clearing the packs but it works just fine. Can even fit the slightly thicker 5s 5000mah pack under the body now.

I see. That sounds good to me - I think I'll check into the 5s in that capacity. I know the Neu's are selling for about $165 each right now in the V5. Too bad I missed the sweet deals they had going for a while on the V1's at about $110 each.

Amain has a 5s 3300 for $130 or so but that capacity is just too small.

I do it all the time. I use a 6s system. See CarSports.com for info.
