bouncing is caused by heavier oils as they dont allow shocks to quickly respond.

fellow racer at his first ever race with revo had is truck bouncing all over as someone recommended him to use very heavy oil like 70WT. I told him to go for lighter oil, he said he will do it but for the next race as there is not enough time between heats :) - he had like 30 minutes :)

took my good old electric screwdriver and changed oil in his shocks in few minutes to 30WT and his suspension came to life and started to work properly.

really? i could never get my revo to handle good from 40wt all the way to 90wt, it is not a race vehicle at all, it would chassis smack worse with lighter oils the with heavier

[QUOTE=wallot;311361]bouncing is caused by heavier oils as they dont allow shocks to quickly respond.

Springs bounce.. not dampening LOL what are you even talking about.. heh..

Springs should be as light as possible only enough to hold your ride height nothing more if you have a stiff spring you will be bouncing all OVER the place on offroad tracks. Thick dampening, or heavier wt oils slow the piston down so when you come down off a huge jump with light oils you will a) bottom and break your bulk heads or b) bounce if you have too stiff of a spring for the oil you are using. This is pretty simple man.. heavy oil will absorb the landing a TON better... most every track out there has huge jumps now so the only reason you wouldn't be running a 60-70wt oil in a revo is your track is FLAT and or very very tiny bumps... but even then if you have too hard of a spring your truck will just bounce around.. heh think of a pogo stick if that helps you any. Also the revo shocks don't work with as thin of oil as the truggy and large big bore style shocks do so forget what you think you know and relearn before you give out much more of this "information". You can get away with softer springs in the revo than the blue, silver combo I mentioned (with the VDP kit), BUT you need to change your oils as well. I beat truggys and I mean 95% of Intermediate level (sorry I'm only a year or so in so I'm not to pro level yet) Anyway Trust me when I say the best possible racing combo for a e-revo is 70wt f/r with blue rear springs sliver front springs and the #2 pistons on the Variable rate kit. I have tried EVERY combo from 40 to 80wt with every spring combo in all variations. The only thing I ever do is drop to 60wt in the rear on tracks with only small bumps, the rest stays the same and my truck doesn't "bounce" all over the place. Keep in mind with a truggy/buggy you can get away with slightly lower wt oils as well do to only having to worry about beating up a chassis, not breaking bulk heads on every landing like you do with a revo.

Here is some old video(s) as proof.. this was last year so my skills have improved :) 1 youtube, 1 on photobucket

Yeah, I happen to already be running 70wt fr/rr with blue springs rear, silver front... it was pretty dialed in as far as suspension went for my track.

Wallot, I am going to have to agree with stum, lighter weight oils just don't work with the Revo I have found.

Here is a couple pics of my track, not very good, and not taken from the drivers stand.

There is alot of rough surface on this track, with a little of everything, literally, rumble, six packs, banks, negative banks, cavern jumps, double jumps, triple jumps, it's a very technical track, makes you sweat!

I am also going to get this little light weight rx batt instead of the 2s M1 pack I am using now.
