We lost this and I didn't save it...I wanna try and get all the angles for the RAD-1 Inclinometer.
H1
H2
H2 Lifted
H3
H3 Lifted
H3T
H3T Lifted
Right now I set my H3 angles at 38 up&down and 38 side to side for 35s and a tbar crank

What are you looking for, max angles reached, or recommended alert settings?

I know with mine on the last trip out I hit 40 on a climb, and we hit 30 on a side slope.

I want to document a good setting people should set it depending on vehicle. Max is also cool to know, 40 is outstandingly steep!

Yes, it was! It was on dry hard rock with aired down tires, so traction was about optimal. But it really did feel steep! I wish we had gotten a pic or video of it.

The manufactured specs for the stock H1, H2, H3 and H3T are all rated as 60% grade and 40% side slope. The percent grade is defined as the rise divided by the run so to convert to degrees, just convert the percent to decimal (i.e. 60% = 0.6) and take the inverse Tangent or arctan. So a 60% grade is equal to 30.963 degrees and 40% side slope is equal to 21.8 degrees. Alternately you can refer to the wikipedia site http://en.wikipedia.org/wiki/Grade_(slope).

That being said, these numbers can be exceeded but by how much depends on many variables such as tire height, payload weight distribution, roof rank load, amount of fuel in the tank, ...

I never really pay attention to my inclinometer other than when my butt starts to grip the seat.

the 60% incline/40% side slope numbers (for the h1 at least) is at full gvw all day long without starving anything of lubrication. I have heard that a stock humvee will roll around 51 degrees...I imagine those numbers are not too far off from a stock open top. Add tires/lift/roofrack and compensation will have to be done by keeping a lot of beer as low as possible in the truck. I have been to 40 and it was very unsettling -- but it's good to know a ballpark to NEVER go past...unless someone is holding your beer or double dog dares ya.

A guy on the hml a few years back put his h1 on a sideways tilting lift and got to 41 degrees until the uphill tires started to lift. His truck was a 4 dr hardtop with a 3" lift and 42" tires (so roughly 5 to 6 in. over stock height)

Holy crap! that is some picture ron. I dont pay too much attention to my rad1 but when it beeps I want to see if I feel like I will roll. The pucker factor always comes into play way before you actually will roll. Do you think its possible 60 and 40 were set modestly seeing there are some pretty crazy drivers out there

the numbers are probably more litigious in nature but are certainly no max...a 40% grade is really quite tame (my driveway is just under that). As I hinted at in my last post, rolling is not the only concern (though the primary one) -- starving the engine/drivetrain components of oil can also damage the vehicle.

If you've ever been past a 30 deg sideslope you know it can be spooky -- I would try to never go too far past 35 in an h2 or 3, and keep it below 45 in a stock h1. Not only for the possible rolling or the afore mentioned oil starvation, but for the sake of the front seats!

Thanks to KS Trekker, who sent me this after I got a shot of him leaning. We decided over time to find inclinometers for our H3's.

I've highlighted the side slope and grade posted capabilities (40/60%):end quote.

can't find the pdf and had trouble copying this. I finally got it to post but as an attachment thru this site. I will work in the larger version. For now just click it to see the large version.
Still having upload problems from Comcrap!!!

I have had comments about my winch rollers sticking out but have not yet stuck them in the ground. This was as close as I have seen them to the ground and don't care to ever touch them!
Without stacking rocks this would have hit my spare, with help from the ground crew I only scrapped the already warp license. My rolling weight probably had some affect on my rear angle. I was testing my expedition weight packed up for two weeks with all my stuff. So an H3 with a daily driver mode of weight would fair a bit better. Same thing going UP the wall.
I figured with a great group like this I could try the weight loaded rather than the first time by myself. Next time I would probably offload some weight in the Motel room! Don't always have that luxury on some trips 1500 miles from home on one way trails with no return for days.
I will have to put a protractor on this one. I know others have done this but it is a good example of what angle will get the front bumper down low. We have remarkable clearance up there.

This one is with the Rad1 installed. This is on the Hunner Hummer Proving Grounds where I first check things out. While not extreme shows an example.

I don't have many shots of a slope example as I seem to be the one shooting all the pictures of others. I will start carrying my remote release but when you get into a situation leaning I want to keep going not stop and pose! :no: Notice there is air under the RR tire! People were screaming stop stop but I decided better to keep moving.

I have a Rad-1 and stopped using it -- I find that a quick glance at an old school inclinometer works better for me vs the constantly changing numbers. It is nice, but for me it's "too many notes"

Share with us the type of Old School inclinometer you use.
I got this out of curiosity as to what some of the angles I was hitting were.
Good to know as a reference when attempting new trails.
I can't hear the damn alarm anyway, too many explosions and too many rounds................................
Contact me if you want to sell your RAD1.

I was hoping for a shot as to how you mounted it.
I have been using those bubble type "analog" on the centerline of my sailboat for years. We call it the OH **** meter!! wonder if that will change to snap?
It has to be on the center line of the vehicle to be accurate, maybe in a dash tray. They bounce around a lot if the one used does not have thick enough oil. It won't show up and down forward and back unless you stick one on the window?
So pm me if you want to sell the Rad1, I will put it on my boat. If it's good enough for the space shuttle I should be ok.

I will probably hold onto the rad-1. The ones I have don't bounce around, you will go insane if you put the digital one in your boat! I have one on the a-pillar just above my visor and one just above thet side window next to me (open top h1 so lots of flat surfaces to mount them on). I am on airbags I so use and depend on them all the time...that's the reason I wanted the rad-1 but the analog inclinometer is better for me...plus Itrying am rying to reduce the amount of electronics I depend on.
