Spartan, tear it down to build it up

[GeoVW72]

BL55: sorry, I don't have a good way currently to setup 5s and I'm trying to focus on easy mods; props, cooling, tweaks, motors

testing was difficult today, good chop but the gusting wind made things unnervnig.

ambient: 37*f

Run#1: 2x 2s P225
esc: 65* motor: 96*
max amps: 93 speed: 37mph

Run#2: 2x 3s
esc: 66* motor: 98*
amp: 82 speed: 39

started gusting really bad and a few spills made me call it quits.

Hopefully tomorrow is better

He is very busy blocking out time on his calendar. You know, all the time he promised he is committed to spending with us on the forums. and more

If your packs are the same size, you can run a 2s and 3s pack together in series

[GeoVW72]

BL55: the packs I have are not the same; 2s 5200 40c and 3s 4700 45c. I do have some 1/8 5s packs that I could wire up, but I'm thinking that changing the motor to something more 6s friendly might be better.

Today was no better and of course when you get the power out the wind kicks up and won't go away

ambient: 42*f

Run#1 2x 2s
esc: 54* motor: 79*
max amp: 47 speed: 26mph

Run#2 2x 3s
esc: 65* motor: 107*
amp: 96 speed: 44



Tomorrow is another day

[Brushless55]

what are your 5s packs?

[GeoVW72]

Losi 5s 4000mah 25c, little low on the c and chunky packs.

ambient: 54*

Run#1 2x 2s
esc: 65* motor: 98*
max amp: 54 speed: 27mph

Run#2 2x 3s
esc: 72* motor: 100*
amp: 92 speed: 43

Run# 3 2x 3s
cable failed
amp: 89 speed: 42


hit a UFO


cable snapped after the stub joint, still chucked in the collet when I pulled it in with the BL RD.

It was my own fault, there was a lot of floating debris after the rain/wind storm we had.
But one of the photographers from a local new paper was there with a very nice camera and looking for an interest piece, so I wanted to give a good show
asked for the pics, if I get them I will post them
no other damage to strut or hull, the stub and prop are gone.

off to find a drive shaft

[JPriami]

Jeffs making some I think. Or graves rc has stock ones I think.

[Brushless55]

I dig that you just keep pluging along with this spartan

[GeoVW72]

Keep plugging till it works

Sorry to be quiet, waiting on parts

stayed busy though:
cleaned up and sharpened rudder

more sensors


As I suspected;
TrailblazerSS = Traxxas employee

Seems I was correct in my assumption that noobs won't clean the grease out of the collet as mr16 showed on the other forum.
Peter, doesn't help and every week the weather gets nicer and people go looking for new toys.

[Brushless55]

keep up the good work bro
and that traxxas site is something else

[PeterTRAXXAS]

All Traxxas employees identify themselves as such on the Traxxas forums.

I don't have any new Spartan news for you, sorry George (and all). If there's any announcement that Spartan has been revised with X, Y and Z, I'll pass that on.

you and a couple here at OSE have given so much for others to go by
traxxas needs to by back my never ran boat and use the parts for warranty for others

[GeoVW72]

I'm back

Never really left , but now I have parts so back to testing.

100% on about assembly lube in the shaft:

and it's nasty gunk that never leaves.

got a tube and liner too, liner is excellent, seems they made a rolling change(one of many I'm sure) and went with some better teflon.
real similar to octura, harder that what came with my boat.
Check this out, old one on left, octura=newer on right.



Ambient: 71*f
4s
esc: 79*
motor: 100*
VAS

6s
esc: 96*
motor:135*

So instead of posting the graphs in I have just linked to them.
So here's the break down:
VAS(Voltage/Amperage/Speed(GPS))
SST(Speed(water)/Speed(GPS)/Temperature(motor))
VR(Voltage/RPM)

I believe that's the best was to present the information clearly,
if anyone has any thoughts on how to present it better I would be happy to hear them

[spartanonfire]

Yeah...I changed my teflon to an octura an could see a huge difference over stock. They needed to get one of better quality.

[GeoVW72]

As I said, nasty gunk that never leaves


Got a new motor back from warranty that looked good, no large stator gaps, so I threw that in.

Ambient: 73*f

esc: 80*
motor: 105*

6s
esc: 104*
motor: 150*

6s
esc: 100*

This graph from the second 6s run best illustrates the issue we're all dealing with; an inefficient motor.
I have heard of a few that have logged the same information that have termed an "operating temp" of the motor, I believe that they are incorrect.
What you are seeing by the rise in temp is a reflection of the core temp of the motor, which I do not believe is a true 1:1 and the temp may be another 10-30* higher.

Disassembled the motor and found:

The rotor epoxy discolored a bit and the motor had the unmistakable toasted smell.

Off to see what a feiago will do
