Good info thanks. The fuel tubing limiters is the missing piece of the puzzle. I destroyed multiple bladders after switching to vented caps. I got so sick of it (and the mess) that I went back to normal caps.

Sounds like the shocks need a travel limiter on the shock shaft...something the engineers should be looking into for sure. Using fuel tube in the bladder is a great work around but this really should be fixed by the factory. Possibly they could look at integrating the boot with the limiters since the boots ripping are also a problem.

I still run the normal caps as the car is running well with them and if anything ever happened during a final it can really reck your race if running vented caps! My spare shocks have the vented caps, with the foam compensator with mugen bladders as they are completely different, they are like a dome, they also seemed to work ok but the best piston and oil combo that i found were in the normal caps and i kept it that way to be safe.

Emm the fuel tubing is on the shock shaft outside the shock like a travel limiter, it isnt in the bladder??

Running the fuel tubing is not the solution. This is going to affect your droop on the car too. When I had my car, Durango did come out with updated bladders and I never had an issue after that.

How would running tubing on the shock shaft outside the shock affect droop ?

Don't they make up travel shock clips that you can just clip on? RPM makes it for 10th scale. And FG modelsport and RS5 have those shock clips that will fit the 8th scale shock shafts. I think its easier than fuel tubing. Let me double check if they fit. I have a 5th scale car at home.. I will just test fit them tonight.

Or another method would be to slip on used o-Rings. it should be easy to slip them on and off to adjust it. Cause depending on which lower arm hole you use, you will have to have different up travel limits.

+1 it does nothing to droop! I only screw the shock bottom up about 3/4 of the threads so i can get droop especially on the front when running on the outside hole on the arm and with the new castor blocks, the fuel tubing has to cover the remaining threads and a little more!

Default Vented caps - shock limiters

Hello guys, just want to share my experience from when I use to drive this car:

- VENTED CAPS, I have achieved my best setups and results using vented caps and losi bladders, my shocks were just more consistent and predictable all the time.
- SHOCK LIMITERS, As soon as I start using vented caps I notice that this can make some damage to the bladders and messed up all the oil in the shock so I limit the up travel in several ways, the best one for me was to use the end of a plastic rod and slice it 2-3 mm thick, then just put it before the shock rod end and this way is like having a larger rod on each shock.
I have tried fuel tubing but it just don't last enough and tends to compress to much on big jumps, I also tried o-rings and worked better than the fuel tubing and are easier to put on the shaft but tend to squezze on the spring cup from time to time.

I drove this car for about 14 months long, from v1 to v2 chassis.
Good luck!

did you run foams? if so where they TD or losi foams in the vented caps,

For the limiter the plastic tube dea is good as long as it doesnt damage the red cap on the shock i like the fuel tubing as its a little more cusioning but it doest compress as much as o rings and ive seen o rings rip for others, personally i use the TD HD fuel tubing or losi tubing and it is pretty strong and doesnt seem to compress as my bladders are always perfect now, although they will tear/rip after maybe 7 or 8 meetings but its not hard to get another couple mm of tubing just my experience that worked for me!

I used losi foams, the limiters have to be used between the shock rod end and the spring cup, if you use it between the spring cup and the shock body you are putting unnecesary stress on the shock bushing during hard landings even if you use fuel tubing or o-rings, thats my experience.

I slide the tubing up but the spring bucket on then make sure the tubing is back down to the bottom sort of in the spring bucket i wud be scared of the spring bucket coming the way you described off but can try on a practice day!

I thought you were referring to the internal shock body.
