Lighter Springs?

[scott_davis]

I have been comparing the springs in my Orion Core to my Orion BB Orbital and noticed the Orbital springs are softer - what would be the effects of using the softer springs on my Core?

You will get longer brush life but not as much acceleration or top end.

Running the softer springs can result in more brush bounce and wear on the comm if you are running outside on a bumpy surface.
It also depends on the rest of the set-up and the car you are running. E.g. you would want lighter springs in a 1/12th car than in a Touring car.
The BB will have a harder longer-wearing brush whereas the Core will a higher silver content brush which needs a stiffer spring.

yes, but's its true that a lighter spring will allow the motor to rev a little higher. it won't give the torque or acceleration but on a smooth track, you will have slightly higher top end.

Yep, basically, harder springs give more torque, and less top end, and softer springs will generate more rpm's, In general, something like a 6oz or 7oz spring would be ideal for 1/12th circuit. Not sure about touring cars as I don't race them! ;)

Im racing off road *:)

So maybe it would be an idea to run harder springs on the BB ? - both motors are using serrated brushes now anyway.......

[Mark Stiles]

Yep I would run a harder spring for off road. As mike said, if your springs are too soft, youll wear the comm quicker because of the possibility of the brushes bouncing.

[Mike Haswell]

In Touring Cars they tend to run Red(+) and green (-) on Stock motors.
Trinity uses purple as standard on Modified.

light springs would also give less 'engine' braking (dead stick braking)

Well will have to buy some new springs then and experiment ;D
