    Just wondering if there is some way to make the new drive shafts stronger? I keep snapping them since the powertrain update.
    I'm pretty sure that the code is all ok, I've been over it several times and I've been using the pickup for a base to work from, the easiest fix I have at the moment is to remove the torque reaction node assignments, as that seems to alleviate the problem.

    just an update, I tried increasing node weights, reducing spring and damping values etc for the trigger beams. The only thing that seems to have made a difference is increasing the deform and break values, I guess they might be tied to torque limits.... That, or the suspension was flexing more than I thought and the extra strength is preventing the trigger beam from breaking when the suspension twists under load.... I'm thinking its probably the latter theory to be honest.

    Shafts only break from physical stress. So there is no maximum torque or anything that would make them break.

    No worries, thanks Diamondback.
    It looks like we need to design some stronger suspension components then to stop the pinion rotating until it snaps the drive shafts.

    What car are you working on Bumblebee?

    I was doing some testing with a extreme powered nonrealistic pickup and my driveshaft kept snapping too instantly when touching the gaspedal , i removed the bed used the slowmo function and saw when i press the gaspedal the differential was going upwards (where the driveshaft/cardanaxle is connected) i changed the rear suspension from the ''live axle rear suspension'' to the ''3-link offroad live axle rear suspension'' and my driveshaft kept intact.

    im testing now with a enginetorque of 23000nm and power of 15000 hp and the driveshaft keeps intact.

    edit: 230000nm and 150000hp now still intact , i think how that stock rear suspension works/handles. you must prevent it from going upwards.

    edit2 oke it snaps a few time with 150000.

    im uploading a video now so you can see what im talking about

    If you are just trying to make ridiculously high hp mods, you can find the driveshaft part jbeam and increase the bounds of the beam so it doesn't break from over extension. I wouldn't recommend strengthening the beam because it will probably break anyways and it will start to bind up the suspension.

    Nah I'm in the middle of reviving a heap of outdated off-roading mods and I'm running into a few issues getting the DW Bouncer stable, although the new powertrain is absolutely awesome.
    nothing will be released without previous authors permission but if all goes well we should have some very happy offroaders soon. ;)

    Its a little of subject at the moment but I have put the stock TCS and ESC into it under a slot for wiring ie main-wiring-abs\esc. Every time I try to load the esc I get an exemption that "speed" returned a nil value. Would not defining torque reaction nodes cause this?

    Btw Bumblebee, how fast are you trying to go with that much power?

    This beast holds my pb of 6.4 over a quarter mile and it was only using roughly 5000hp. Needs to be updated and textured though.

    This was purely for testing , the pickup now has around 2500hp and 4000nm , and it can still wheelie at 300kmh lol.

    My next step is to try to make the chassis a bit shorter so the car can flip itself :p. Its gonna be a pain though since i really dont know how to do that.

    Haha, nice, I might be able to help out with that, I was thinking about making a really short wheel base pickup for 4w4ing, but it would easily be adapted for flipping.
    Have you had a look for a SWB pickup, I think there's one on here somewhere
