Another day yesterday,,,another snapped cable after 4 runs..............................................

Dude... I have NEVER snapped a cable in 2-years of racing P-Spec OPC tunnels... and I'm using a BJ26 motor with tons of torque and over 4" of pitch in the prop...

No one that I can recall in our club has had any issues with their REK lowers either, regarding snapping cables.

SOMETHING has to be wrong with your lower to be causing this to happen... WHERE is the cable breaking? Is it in the same place every time? Can you take some good pictures of it and post them?

A 9XL is quite a bit of power (I think that's what you said you were running), so maybe if this keeps up, you might need to consider upping the lower to a 7.5 unit...???

Thanks Darin;

The first snapped cable was with a 9XL,,,all others have been with the UL-1 motor.
Its always right in the middle,,a very clean break.

I now have one left that I installed last night. It has been shorted even more and the ends sanded to allow it to "float" more than the others.

When I inset it, there appears to be nothing binding etc that I can detect.

If this one fails, I'll have to reconsider things over the winter as this is getting rediculous...

I have snapped a few with my bj combo, but on sat i raced with a ul-1 motor and a new brand of cable ray fuller gave me and so far its been good, i also used a pipe cleaner to clean out the tube this time. There could have been grit or metal shaving in there

The old ones i broke were the hyperformance cables

[Doby]

All of mine were Fullers.

Is the cable shiny where it breaks? Can you open it up and look for a burr in the tube?

When are we going to make those charging harnesses?

[6S HYDRO]

They were hyperformance cables from fuller yes, i believe he has some new ones now

[Doby]

The last one that broke came from Fullers 2 weeks ago.
No the area was not shiny.

I ran a pipe cleaner in the tube to feel if there was anything in there that could cause this...seems smooth.

Last week he had a big bulk bag of them, these ones seem good i did not shorten it at all. The rek unit have the most harsh angle on them than any other unit. I was looking at the other setups at the race this weekend.

[Doby]

Good to know that , thanks 6S......I might have to consider a K&B lower if this keeps up!

[6S HYDRO]

The os lower is what was on that other all white one. Real nice unit, and way more of a easy bend on it

[Doby]

Thanks,,,any idea where to get a OS lower unit?
