My Spartan build thread

[Spartan]

If the two 3s packs were in parallel than that would just be like running on one 3s but double runtime.... How many wires do you have coming from your ESC to the battery connectors? Should be be TWO negative (black) and one positive (red).Pictures may help...?

Yeah I'll post a pic...sorry for the confusion...

That's a serial connection. 2 x 3S will give you 6S

Just a heads up, keep an eye on your Deans connectors for running hot. They are great connectors, but a bit under rated for the Spartan. I ran Deans in everything until the Spartan, I have now standardized all my boats to EC5's.

Thanks for the pic, dag-nabit is correct, as like most of the time-well always-...
I just had a thought, if the TRX/Deans are acted for a certain amount of amps 50C batteries wouldn't matter much? Maybe I'm just blabbing...

Ok, I have them in everything. I will keep an eye on em... Can't wait to get this thing in the water... N e ideas on what should I use to lubricate the strut. I got the OSE one. So not sure if I should use oil or grease...

[Spartanator]

Try some of the grim racer grease, the stock isn't think enough (IMO) maybe if you live near a HD/Lowes or even a Marine shop pick some marine grease up...

[dag-nabit]

Grim Racer grease is good, have used it in the past.
Now I just pick up a cartridge of water resistant wheel bearing grease at the local hardware/auto supply. It's inexpensive and you get enough for 3-4 seasons.

Thanks guys.... Well just got the flex cable in n......... Hold the phone.... The .187 cable won't go in!!!! Wth. I have the OSE strut...

[dag-nabit]

Was the OSE strut specifically designed for the Spartan stub shaft?

The Spartan flex cable has a bit different prop stub on it than most RC boats. The measurements escape my memory at the moment, I will see if I can find them.

The .187 cable fits the stock strut, but you do have to remove teflon liner from the stuffing tube.

Kevin

EDIT

OK if memory serves the Spartan stub shaft is 5mm diameter, stepped down to 3/16" (.187") to accommodate standard size props and drive dogs. (NOTE: FYI many Chinese manufactured boats run 4mm cables, with 3/16" stub shafts)

If your replacement strut has 3/16" (.187") bushings in it, it is possible the .187 flex will be too tight to fit.

You can see the "step" on the Spartan Stub just to the right of the drive dog flat. This could be the difference between fitting or not.



The "good" news is a standard 3/16" stub shaft size gives you many more options to source flex cables. The "bad" news is, it appears you are limited to .150 flex cable diameter, or, a wire drive.

Kevin

[Spartan]

Yeah I got that... It's just that the shaft doesn't go in the strut.. not the cable but the shaft...

[dag-nabit]

OK

Would be the same issue, If the strut is 3/16" and the stub shaft 5mm, it will be too big to fit through the bushings.

I believe you mentioned it is a Jeff Wohlt flex cable? His Spartan cables are fitted with the same size stub as OEM (5mm).

But you are right, the flex should fit since 3/16" is same as .187". It is the 5mm stub possibly not being compatible with the OSE strut.

Here are some mods I just did in the last 48 hours. I Will find out how it will all work on Monday. I installed a Leopard 4082 - 1600KV, 200A ESC and adjustable turn fins with stainless hardware. I will try a 442 prop for the first run. I have other props to move up too. The next part I will try is a dual water pick rudder. I may try one that is a little longer in length, I heard positive results.

Well this Sux... Now I have a part I can't use... And I really wanted to use it too... Jeez...guess I'll have to use the stock one... Just fill it with grease I suppose.

[Spartanator]

I WAS thinking to get the wire drive and then pick up a strut from OSE but guess not now...
