Rotor lifespan

[Sanders83]

Hi all,

How long does a rotor last? I see people on here saying they've ordered new rotors frequently and wonder if I use mine alot how long it will go on for without needing new parts.

Cheers

If you don't mistreat it then it can last months but
when doing 90s runs the rotors can crack in the fins
but this is only if your using it at very high speeds for
long periods of time I've found out.

It's not going to go through leisurely use of the
ball only if your using it frequently to get for
long periods if time. I think the cause of this is
the heat the ball produces has something to do with it.

Cheers Pete. Has anyone got a cutaway photo of the inside of a powerball and what all the parts are?

I could take a pic of all the parts for you if you want, won't take me long

Rotor reliabilty isn't great tbh, i've been powerballing since february and have already had to replace 3 rotors. Two started vibrating slightly, which affected their speed and the third, a neon green developed cracks in all four rotor fins. When this happens you'll feel it .

I was very careful with these powerballs and never dropped them but your technique can have a lot to do with it. However even with a perfect technique its inevitable that a couple of rotors will break if you use them a lot.

On a different note has anyone noticed that the Screamer rotor seems a hell of a lot sturdier than the 250Hz ones. It seems to have much thicker rotor fins and in general feels a lot more rigid than the others. This powerball is also a newer model released by NSD (I think) so hopefully this type of rotor design will be adopted for the 250Hz models in the future, I'm sure this would reduced the risk of cracked rotor fins quite a bit.

EDIT:

here's a comparison between the two just to show everyone who doesn't have a screamer.

250Hz



Sound Ball "Screamer"



So as you can see the difference in the fin thickness is quite dramatic.

Hey Sanders83

I did a video of the signature close up if you wanna have a peak, it's a beauty! http://www.youtube.com/watch?v=vid9kVvWcRE

Is this what you're looking for?

You're quite right Linus - the rotors have been modified recently and are being rolled out right across the range to ensure that they are more durable and are less likely to crack - even at consistently higher speeds.

They should be available on all models shortly.

The rotors have been changed to incorporate thicker fins and also the washers have been changed to a thicker version which should eradicate wear to the support band from the rotor axle.

I'm going to do an FAQ on it over the next few days and will post the differences then with images.

Cheers Pete, Enda.

Will the new updated rotors be sent out as replacement parts for old PB's which need new parts or is it just new models?

Nice pic. So whats the "ring" bit refered to as?

we calls it the support band


Great news Enda, looking forward to see how the new rotors perform. The screamer seems to be a little bit slower than the 250Hz rotors but im guessing that's because of the added air resistance caused by the "Sound holes", so can we expect to see the same speeds from the new rotors or will they be equivelant to the current 250Hz models?
