Well my NB friends, Once again the build of my f-350 is under way.I was going to run and ALU.chassis. But then I saw altered sheep's buggy build and I really liked that idea of using coat hangers. So I thought that I would give it a try sense I all ready had all the stuff to make it happen. There are a few things I wanted to keep so I came up with a few of my one Ideas (I think) Li i really like the long drop shocks. Now I do think oil filed shocks would be nice but the problem is that they really limit the amount of flex. I enjoy using "BIGFlex" when I am crawling around. So ne-ways lets get onto the pictures.



I was kinda using the stock chassis for a guide on the measurements.


I how ever shorted the bottom to only 4" x4" This will hopefully increase the "Break over" angle.

Actually, the type of shock used by AJ is somewhat like a droop setup. The shocks extend downward to make contact with the ground. With a droop setup the springs are really important to control the shock's rate of unloading. With the proper springs, a droop setup can be run without oil - its just not really a good idea because the oil lubricates the shock body/piston.

the shocks on a crawler need to work a bit different than on a basher. Unlike a basher, a crawler does not move fast enough to need the shocks to soak up bumps. A droop setup would never work on a basher - its does not really soak up bumps but it does make sure that the shocks can extend - most times quite slowly - to meet the ground.

I'd be curious to see how the design AJ is using would work in a true crawling situation.

do you think the glue will hold? what did you use? I'm thinking of doing a fake roll cage for mine but was not sure what glue to use.

I just used a hot glue gun with "Hot glue" the hold works really well. I was impressed. I think it will hold up Fine.

They would not work good at all. The shaft is able to move freely unless it is fully compressed. The spring only works when the shaft is compressed. Look more closely and think about it.
On a droop setup/ crawler you can run shock absorbers with out springs, The oil works on both sides of the stroke. Ride hight/droop is controlled by the weight of the oil used.

Most RC shock absorbers use a rubber O ring. So the O ring is actually only Lubricated on the side that meets the oil. The entire O ring does not get lubricated unless you actually put lube
on it.

Reread your post and think about the post like some other person wrote it.

One of the benefits of a motorcycle running a spring inside the absorber is, that going off
a jump or hitting a bump fast; that the spring
takes up some of the brunt and does not blow a
seal.

For the most case a liquid reacts to the rate of change of velocity.
Sort of like if you were to fill up your bath
tub with just enough room for your body and slowly sit in it. You could do it slow enough
were you could actually have the water over the rim of the tub since the water has tension. Now if you were so sit in it fast the water water
would go all over the place.

Same with oil fact or fiction

Nice job AJ..

Is there anyway to get the battery laying flat?
If there was,, You could possibly use a good strong velcro and use the battery as a weight move it around to get the perfect balance. Just a thought.
