Ok so they are linear.
Now my question is : What is the difference between linear and progressive springs???
I guess the feeling of the car....but can you explain a little bit more

Stew Noble

Hi,

The 2 hole pistons won't feel a huge amount different, but the full potential of the setup won't quite be realised.
I'd definatly recommend purchasing a selection of toe blocks, the 2.5* will not allow the car to rotate so much, which is important indoors.
The 2.5* is usually used outdoors to make the car feel more aggressive upon entry.

Feel free to try it with the 2.5*, but on carpet the 1.5* and sometimes the 1* are best I've found.


For all those discussing springs, here is a chart of all HPI springs, I think it's a little easyer to read and compare than just a text list of springs, almost all Cyclone drivers use springs from the Pro4 set.

you have to have the monster truck shocks to be using these...

progressive springs...the more the spring is compressed the harder it gets.
linear is consistant when compressed.

Cheers Stew should i use 40wt oil in sted of 45wt due to lack of holes

Stew Noble

Yeah, that can have a similar effect, wont be quite the same but pretty close.
A note to that setup is that i used Pro Competition shocks, which give a slightly different action to the normal type anyway, so it might be a case of having to play with the shock internals (oil, o-ring, piston) a little to get it feeling to your liking with the normal shocks.

Now i am confused what type of springs should i use going off Stew's setup i was told that the yoke springs were the same as the hpi one's only diff was that yoke were white and not black is this true or not do i need to buy hpi springs if so what type there seams to be 3.

Stew Noble
