Can you post a close-up pic please Martin, be useful to see what you did and how you got the 100 into your yoke with the cap board attached

Cheers

Paul

the armatures are sometimes not shimmed correctly. you can add shims if you want to, but it usually is not necessary.

here are pics of a genius 100 in my bd.

i did not use a cap board by that time as it was not yet released but i could easily add one.

Thanks Martin,

What power caps did you use in these photos? did you notice a performance difference with the board?

does anyone elses EVO3 3.5 sound really loud? Mine is louder in comparison to my LRP brushless. I know the GM has a fan inside, is that the only reason for the sound?

Has anyone run their GM 100 in sensorless mode? I

If so:

What motor were you running?

How did it feel?

Is it as simple as removing the sensor lead?

Thanks.

none of our teamdrivers uses a sensor wire.

there is no difference in driving.

i have tested motors from 5,5T to below 3,5T. no problems at all.

and yes it is as simple as just pulling the wire

either at least 4 470s

you can dremel away 3 caps, this makes it much smaller
which caps can you dremmel off, the outer most 3?

Thanks

you can remove the 3-cap row

to do this unsolder all caps
then cut the board

It is mostly all about what feeling you like best.

This differs quite a bit from number of windings and if it's star or delta wound. These are my current favourits:

6T delta (coming soon) 12,5mm

3,5T 12mm

7T delta 12mm

4T 12,5mm

4,5T 12mm

Hope I could help you.

Greetz.

Martin.

Hi, could you be more specific about the differences in windings and rotors size?

I race exclusively rubber tires, on low traction asphalt. I do not need much torque, but i need a fast motor because most tracks are 1/8 gas car. What would you advise?

Also, energy efficiency is also important (5 cell)

Thank you
