Spartan on 4s?

[Smoothops]

You can run 5s. Many including myself do it ALL the time. As long as the packs are the same mah and c rating (i also prefer same brand and same number of cycles) you won't have a problem.

Thanks so 4s or 5s would be fine stock. If you change prop same thing or that is putting stress on the the moter or esc causing
damage

It's gonna be slow on 4s but will run. 5s maybe the happy medium for this boat. 4s is slow and 6s is gonna blow so try her on 5s....

So 5s and a new prop?
Thanks for the help fellas

With this motor being a cheap 2 pole motor propping is gonna be tricky. Even if you pick the same size prop as the stock in a metal prop the amp load is gonna slightly raise because plastic and CF props flex under load and metal props typically maintain their shape under load.

What size is the stock prop?

[Shaun78]

ya 4S is very low 30 mph range with stock prop, maybe 35-40 tops on 5S with a different prop. The Spartan needs 6S on stock setup...Maybe 5 S on a different motor to get 50mph will work.

The Spartan needs FAR from 6s on stock power. We have all read and seen the results of 6s on this boat. I myself wouldn't be focused on hitting 50mph, I would be focused on making a reliable setup. You hit 50mph but at what cost. It's just a number...

* Just my 2 cents.

The stock setup equipment should have no problem on 4s provided it is lubed properly.
scratching 30mph with the stock prop on 4s is difficult and needs to be setup properly.
In recent testing I used a larger Prather 225 prop and it's consistently in the high 30's scratching 40. However the amp load is approaching that of 6s on the stock prop as well as the temps with my modified cooling setup.

stock prop: 42mmx 59mm
P225: 46.7x 71mm

In my honest opinion you do need to stop focusing on the speed number, run it how it is on 4s and if you want to go faster try a slightly larger prop with a few of traxxas's cooling mods to be safe.

4s setup;
strut: level
trim tabs: level or remove
batteries: rear, move forward 1/2"-1" if the boat is unstable.

AGREED!




People focus on the number way to much.... 50mph isn't a big deal, a stock ul1 can hit 50 on 4s with a prop change and do it RELIABLY!!!!

JMHO of course...

With the new and new brushless motors coming out the sky is the limit. Sadly Traxxas went the route of Cheap instead of efficient.

yeah ive seen shaun78 spartan hit 30.7 on 4s and a week later he hit 48.1 and later that day 50.7 both on 6s and the next run..... well he's still looking for the pieces that blew cause it sounds like a chitty chitty bang bang car now!!!..... should have bought a hobby king spatoon..... :)

Ive got a 15" micro mono deep v with a $12 motor & $20 esc that hits around 50mph on 3s & is reliable, Why would i wont to spend $800+ on a Spartan with upgrades to make it work. Martin.

[Shaun78]

im the one suffering but I still like my spartan. Ill just have to get another boat. Its like owning a real cigarette boat. You go out to run it and hope that you dont break anything. Ill just buy another boat too.

[Shaun78]

The spartan is boring on 4S is what I mean....for me it's 50 MPH or close or not worth it. my opinion. 30MPH thats no fun

I found this vid of them running both

They must have miss labled that, looked like it was pretty quick on 4S, quite a difference from the included 7-cell nimh's. The way everyone talks is that it's not really much faster on 4s over the Nimh's, that video kinda shows differently. I'll be plenty happy with that performance running in my cove at the lake!
