Sorry for the thread necro, but just wanted to say this appears to work OK as-is in 1.4.1, except that the ability to change the paint job is missing.

This mod's such a boon for early-game science collection round KSP for Field Research contracts.

I imagine most part mods should still be fine.  The paint job switching requires a working firespitter core, which I believe is not yet updated.  Similarly, the Speedo and such won't function (they still appear) unless there's a working RPM core.  Neither of those are hard dependencies though.  Just extra features if they're installed.

I keep trying to write mm code to get KSP wheel to take over the wheels if it's installed, but as yet, I only have very squishy suspension or kraken suspension.  But again, I'll generally only add such things as mm patches that require the other mod exists.

And I haven't really got to looking at 1.4 yet. Maybe this weekend

Oh I'm not at all pushing you to update this. I'm just happy to find that it still works.

Although, if you do ever get round to updating it, perhaps you could consider renaming one of the wheels. It's a (very) minor niggle, but both roverWheelM05 and roverWheelM06 have the name "KerbinRover Offroad Defender Wheel". This means if I'm doing a "test KerbinRover Offroad Defender Wheel" contract, I would need to put both types of wheel on to be sure I can complete the contract. 

Currently I rename one of the wheels with an MM patch, and I'm quite happy to continue doing so.

I have done a few longer-range expeditions, there seems to be a very small patch of another biome to the south of the KSC, but it can take a bit of finding.

In one of my crazier moments I fitted an RTG to one and used it on the Mun. It seemed eminently sensible to explore with a nuclear-powered Land Rover.

Either a trailer, or one of the larger 4wd vehicles would be better for long expeditions. There was the 1-tonne Land Rover, used by the British Army as a tractor for light artillery, which was also used in several real expeditions, but the Pinzgauer isn't very different, and it much more widely used.

It's good to hear that it's still working, and I think the Firespitter plugin has now been updated.

I've had this mod for one day and already it's my favorite rover.

I do have one question. Shouldn't the CoM be lower and further forward?

It would also help with the inevitable rollovers.

Something I'd like to see added to rovers in general is a tweakable steering limiter and perhaps a speed governor/cruise control. It'd make keyboard steering easier.

I have a feeling there is a cruise control in one of the mods like mechjeb, but I don't know for sure. And yes, it would certainly lesson the load on that middle finger tendon that runs up the back of my forearm.

I'll check the CoM. I think I did that once before, and it may have ended up overwritten at some point.

Only just got around to checking the CoM and unbutchering the imgur link (gotta love the way the imgur links vs forums interact).

So, yes, I'll probably drop the CoM a bit, but not a lot.  It should be possible to drive on a sideways slope about 45degrees, which this image makes it look like you almost could...

But due to suspension squishing around, you can't.

Your CoM joys come from the collection of big tanks of stuff on top though.  I wish I could do up a trailer to put those in, but I flat out have no idea how to make that happen.  But, if you glue a chunk of 6 propellant tanks to the top of a Defender, it's CoM will go upwards.

Those are just Goo Canisters. I was collecting science from the KSC.

But the Defender has the same problems when nothing is on the roof at all. (I thought I'd stripped it before the screenshot and apparently I didn't.) I've got a workaround by reducing the front wheel traction, but now it slides down hills.

You might check out Feline Utility Rovers for trailers. They have a way of doing it, but the trailers bounce so much they don't work very well for me (I might be doing it wrong.)

Maybe one of these for attaching to the back?

I keep meaning to reply to this and keep getting distracted by stupid life. Does anyone have actual real data on a land rover defender centre of mass? All I can find are roll over angles which will include safety margins for all sorts of things.

Approximate centre of gravity heights for these base vehicle specifications in the EEC kerb weight condition (ie unladen + full fuel + 75Kg driver; no options fitted) is as below:

Vehicle Body type Tyre size C of G height above ground
110 standard Cab 7.50 R16 665mm
110 heavy duty Cab 7.50 R16 665mm
130 Cab 7.50 R16 665mm
130 Double Cab 7.50 R16 667mm
Quote

Based on the axle weights and 110 and 127 inch wheel base I calculate that:

for the 110 the CoG is approx 1060mm for the standard cab and 1067mm for the heavy duty cab, behind the center of the front axle.

for the 130 the CoG is approx 1311mm for the cab and 1386mm for the dual cab, behind the center of the front axle.

Awesome searching. Thanks.  665mm then, times 0.64 because Kerbals. I shall fix. Probably on the weekend.

I shifted the CoM to approximately where it should be.  I can't directly set it as the wheels are separate parts, and doing the maths for that would just hurt my brain.

Although the CoM adjustment was just done with config, I re-exported the main rover body from Unity as it's been bugging me that the material for the flag/logo wasn't marked with the right material type, so transparency didn't work.  Esp annoying on logos like the Kerbin Rover logo.

The updated 1.0.8 will work with older KSPs as well.

The car's body fabulously cycles through red, blue and yellow hue on the launchpad for few seconds, and then wheels break from overstressing.

1.4.5, modded

It's working fine in my install.

Is there something generating heat attached?

This time I just installed it from CKAN on top of everything and ran a body with 4 wheels and nothing else. Wheels did not break, but colors remain:

I haven't seen this with any other capsules so far, if it goes away somehow I'll let you know.

Edit: it was "critical temperature gauge" mod.

Oh. Weird I was going to ask you to check if there was a broken firespitter or something after seeing the gif.
