I have ran the 9xl on 12cells as well. It will make the stock titans look bad still. Don't run hot either.

Does the strobe come with its own spring/nut or do you use the stock ones? Because I fitted mine with the stock spring, but it doesn't seem to be too tight. The previous owner came up with an overkill solution involving a small spring off a real car and a massive modified nut, but I'm hesitant to fit it due to the extra weight it will add.

You need to use the stock spring/nut.

Depending on the motor you use .

Leroy had some issues with his 2250 on 26 cells.. my 7XL on 18 cells managed with the stock spring/nut.

It does not come with a spring or nut... but my stock ones seem to hold up fine for 12cell 9xl... though any more and I worry about breaking other stock stuff :027:

Thanks for the replies, I'll give the stock one a go, I will be running a 9XL on 12-16 cells (maybe blip upto 20 just to see what its like..). I was just a bit concerned because with it fully tightened, I can hold the spur gear still, and as I turn the nut the slipper kicks in quite easily letting the wheels rotate.

That's odd, i think i can damage the thread if i do it like you discribe.

One other thing;
you did removed the grease from the bearing that came with the strobe?

Remove the grease!? Oops... how, exactly do you do that?

I removed the shields with a needle and dropped the bearing in thinner.. and used a tiny little bit of dry lube.

What does this actually do, Serum?

I have not removed the grease from the bearing. Could you please advise me on why it would help?

Something must be wrong on my slipper if it shouldn't be like that. The exact components on my top shaft are:

Hex backplate, slipper disc, slipper pad, washer, bearing, washer, slipper pad, slipper disc, hex frontplate, spring, washer, nut. With the strobe obviously riding on the bearing. Does this sound right?

Is your washers to thick and are they used for spacing the bearing in the center. You shouldn't be able to hold the wheel and turn the spur by hand. If the washers are hitting instead of the pads this may explain things.

As for removing the grease. When the slipper gets warm and spin around at about 10,000rpm the grease in it becomes thinner. It eases out and onto the pads. The pads and grease don't work well together. Inturn you will have a melt down of the other slipper pad cause it will have all the friction on it. Hope this helps.
