It makes sense...

but let say a hard spring is used and it enage at 10k rpm

VS

a softer spring but higher tension ( the tension is set to the same as the high spring ) therefore it also enage at 10k rpm...

Then what will be the different?

Thanks!

It may not be possible since you have to tighten softer spring more and you'll see clutch will slip too much.. even quarter turn of spring nut effect clutch slip..

Hi regulators are only needed if you are runnng a lipo, Rx lipos run at 7.4 volt and servos are only 6Volt rated so if you are running a nimh or nicad battery then you dont need a regultor whatever the servo model.

My question is, should i loosen the clutch spring tension more or should i change to a harder spring? what the different between higher clutch spring tension and using of harder clutch spring?

As for the spin at corner exit (once exit i throttle) is it that reduce the caster angle will improve?

Thanks!
sounds like your car is a bit stiff in the rear, there are a few things you can adjust on the car to get consistant rear traction rememebr one thing at a time not all at once to find the right setup,
try and stiffen up the front a bit first try a bit harder springs and or soften a bit in the rear with a softer spring, check your shock angle on the towers maybe try and lay the rear down one and go from there, also droop makes a big difference try and increase the droop in the rear I think I run 6.5 ride height and a droop of 4mm ( depends on how bumpy the track is), dont forget to adjust your rear arm travel so you chassis does not bottom out. take a look at your tire shore also maybe try a shore softer??
its a start see how you go with these small adjustments and go from there
cheers

lets just say , i stalled 2 sanwa ERG servos and measured the amps it pulled, it was like 1.9 amps each. so to have it on full lock turning into a corner and hard on the brakes, it will trip the reg out, and possibly damage the reg or worse, it could generate a loss of signal to the reciever. you dont want to be on full throttle when that happens. so i have always used one digital steering servo and one std metal geared servo since i had a runaway. thats why its so important to set your end points so neither servo stalls when racing.

cheers
i'm using the nosram 1500mah lipo.
slightly bigger than the premium power 1300mah that u're using (my frd using too) which doesn't fit perfectly in the stock battery location.

i gotta modify my radio plate slightly to get my lipo to fit.

Asil
agreed...

jameslow:
better to use a harder spring than tightening a softer spring...harder spring will give u more consistant operation than a tightened softer spring.

I would think teh problem could one of 4 things ie:
rear shock angle.
rear roll centre.
too soft rear sway bar.
too thick rear diff oil.
or combination of above.

mostly likely too soft rear sway bar.
is 20k oil rear diff considered too thick?

The thicker diff oil in the rear will act like a solid axle, try 3000wt or 5000wt.
Also try a stiffer roll bar setting and then lower the rear roll centre by taking out a spacer or two on the rear outer upper linkage.

I have a bit of an issue with the new rear bulkhead. When i put the rear lower hinge pins in the outer hole the dogbones aren't long enough, even the front cvd's in the longest setting are still to short. I'm using the flying wing arm (for the roll bar) but with the old G4s hubs and links and with the G4s rear brace on a G4+ chassis.

Can anyone recomend a longer dogbone or cv or am i doing something totally left field
