I guess that if they are sold at all in the US must be through Schumacher that also markets the CS dyno there.

The powermax Silver is dual shunt, almost silver in color and it's the only brush I use.

They last for ages... to give you an example:

I had a Reedy Ti 12x1 with the original brushes that took around 10 packs to replace, then I installed a set of Reedy 729 Quasar brushes that lasted for 4 packs.
From them on till the end of the comm (!!!!) I used only 1 pair of CS!!!

Practice, races etc etc. At around 30 packs I stopped counting.
When the comm was gone there was still enough brush to run a few more packs.
No discoloration at all and the comm is barely touched in one pack.

However they changed the length of the brush in the new ones (since 8/2002) but the compound is still the same.

Look at this graph
Reedy 12x2 with 10-30 Orion Brushes 24 timing
Max Eff: 72% Max rpm: 38698 Max power: 139W Max Torque: 66 Nmm


Reedy 12x2 with CS Silver 24 Timing
Max Eff: 77.7% Max rpm: 40671 Max power: 158W Max torque: 70.28 Nmm

Orion Core 12x1 with 10-30 Orion Brushes 24 timing
Max Eff: 74.8% Max rpm: 39869Max power: 171W Max Torque: 81.61Nmm

Orion Core 12x1 with CS Silver 24 Timing
Max Eff: 80% Max rpm: 41713 Max power: 184W Max torque: 83.97 Nmm

The results are always amazing when compared like this. The result was more responsive motors and greater top speed. Better all the way.

Hi Antoniop,

Thank you, for these tests.

May I ask you, if possible to test the same motors Reedy 12x2 and Core 12x1 with the Reedy Quasar brushes.

Thanks,

Ralf,

I have made some tests with the Quasars (I have around 200 tests with several combinations somewhere on my PC) and I can remember that the power and torque was above the Orion 10-30 but still below the CS in all the parameters.

However on the track the Quasars didn't last more than 2 packs running decently!!! On the 3rd one the car was loosing speed and acceleration because they just go away very fast.

Knowing this I prefer to have a safety margin with 10-30 or CS and CS is now my brush of choice.

I still have a Quasar pair around here and I'll make a few comparative tests.

The other brush I would consider (I found it very good before I found out about the CS) was the Corally Q Brush. Very powerfull, medium life but a little harder on the comm.

the CS "likes" 150 springs from Orion. Preferably the ones with double wire

Look at the improvement on the Ti 12x2 I talked about. After some tests with springs, CS brushes, alignment etc etc

Before
Reedy 12x2 with 10-30 Orion Brushes 24 timing
Max Eff: 72% Max rpm: 38698 Max power: 139W Max Torque: 66 Nmm

After
Reedy 12x2 with CS Brushes 24 timing 150 Orion Springs
Max Eff: 78.6% Max rpm: 40334 Max power: 194WMax Torque: 87.28 Nmm

What more can I say....

Hi pops (no pun intended LOL)

I'm pretty sure that they just exist in standup configuration.

Now this kind of leaves me sad coz I wanted to use them on the new Reedy Kr and they use laydown brushes....

Popsracer,

you are welcome

I received an answer from Frank Klein - CS Electronic manager and he confirms that these long lasting brushes don't exist in laydown version for the moment...
so the good thing is they may release them later ... ??? will ask for precision.

Pops,

Some of the CS products are imported to the US by Schumacher. If the channel is open probably they can get them from you.

CS is a small company and if they start selling all the production to the US we can't get them anymore in here
