Spartan .187 drive cable

[Rcforever27]

I just got 2 .187 drive cables from Jeff wholt , they are alittle bigger i'n diameter than the stock, which I knew... But I heard i'n here someone mentioned to take the Teflon liner out and it'll fit? Along with using quite a bit if speed grease? Thoughts?

Sorry Jeff wohlt.... Spelled the last name wrong... Lol

Yep, that's the ticket.

The nice thing about the Spartan is, if you do wear through the stuffing tube over time, it is inexpensive and easy to replace because it isn't glued into the hull. :thumbup:

True thts what I figured already have one extra..... Just waiting on some hardware and some wire & connectors and I should be able to finish building the thing...the only other thing I might do is use 4 ,4000 mah turnigy lipos i'n series/ parallel but well see may be alittle heavy.... But not to concerned about it.... Although boats being heavy are slot different than a car being heavy.... Lol

There is a school of thought that a little extra weight might help stabilize this boat.

It would likely cost you a bit of top end speed, but if you are looking for longer run times and stability, rather than breaking speed records, it might be a good set up.

I'm going to try the same when we finally get some liquid water around here.

Yeah I hear ya... I'm gonna experiment too and see wt works best...

with the 187 cable can you use the std Colet ?

I can't see it would fit, I'm pretty certain a new Collet will be necessary. 5mm motor shaft to .187 flex.

o..std is 150 so 187 needs a new coupler. More cable coming today...was out of 150. An 078 wire does very well on these also.V

Jeff,

When going to the wire drive do you need to change anything on the stuffing tube?

New tube?? or different liner??

Thanks

[Jeff Wohlt]

I think I would try it on stock liner. Most of that is metric so hard to fit new stuff.

:help: Hi Jeff Wohlt I have a question , I receive the 150 drive cable from you , but is thinner then the stock cable that came with the spartan , is that normal ? also is loose inside the liner do i need another liner that will accommodate the new cable , :confused1: thanks in advance .

[Jeff Wohlt]

Nope...run it as is. I think the Octura cable is stronger. 150 is actually about 147.

[mavdriver]

Ok will do thanks for the response .

That is interesting.

Checking the Spartan flex cable with a caliper three or four places along the length it is dialing in at a true .150 - .151 diameter. (3.82mm).

Not that 3 one thousandths is very significant on a flex cable.

Kevin

[Jeff Wohlt]

Yep...if they are breaking on 4s then there are other issues.

[Jeff Wohlt]

Maybe the stock cable is too tight in the liner.

[mavdriver]

They are breaking on 6s from what i understand it seems rust gets in between the wire add stress to that , and snap , so far I had no problem with the stock cable , but I thought I would upgrade anyways maybe I should had bought the 182 :doh:

[mavdriver]

Maybe the stock cable is too tight in the liner.

Not really the wire slides nice and easy when I go to grease it .

[dag-nabit]

I'm guessing here, but unless folks are running high Kv motors, or pushing very large props, a good quality .150 cable should suffice.

With all the other issues the Spartan has had, I find it hard to default my confidence to the stock cable being manufactured to a high quality standard.

I have a couple of Jeffs .150 cables on the way and will give them a chance to prove themselves. If they don't hold up, I will switch to .187 or consider a piano wire drive.

As for rust on the cable, if you are doing proper drive line maintenance, cleaning the flex cable after running, storing the boat with fresh grease on the cable, and making sure the cable is well greased while running. I would think rust should be a fairly minor concern. But as previously stated, I'm not willing to place a lot of faith in the quality of the stock components in this boat.

6S is going to be pushing a 150 cable no matter what...the boat hops a bivt and snap!!
