What are you working on??

[Midcoast crawler]

So, another trans and esc won't fit. Need to get a winch and bumper

 

[Kaler]

Ya my settings are almost the same as Robert's also, so I guess I'm heading down the right road. I'm gonna play around with throttle curves a little and see what I like. Thanks guys.

Well...it's MOSTLY done. Here's a few pics:

The last pic shows the Pitbull tires I desperately want to run but they have major clearance issues on the front, plus they would be a 42" tire on a Toyota! The forum is full of the TF2 and those Pitbulls so I might just bite the bullet.

I also made some "mods" along the way to help with durability, Axial driveshafts, shimmed axle pinions, re greased trans and transfer case and CVDs up front.

I think it looks better with the mags wheels and smaller tires myself. So far Ive got one axle built. Magine that. had a frozen bearing on the gear side of the diff. that took some time to get off. Never had them apart since I bought it 8 years ago. Luck me its got HR beveled gears in it. Cvd's and new bearings in. Aluminum chubs and knuckles on. On to the back axle.

 

[robertjpjr]

That tf2 looks badass.
I've wanted one for a while. I may just have to check yours out next meet up, assuming you bring it.

I think the Pitbulls area bit big as well. Something in between the two sizes, if I had to choose.

 

[skybolt]

Thanks guys! I agree that a size in between the two would be nice, slim pickings in 1.55 though, RC4WD has a 1.9 mudthrasher that's in between, but Im afraid the 1.9 wheels will make it look odd.

I also have some suspension tuning to do, I bought King shocks per all the recommendations but wasnt happy with the fit, there were clearance issues. Im running plain old scx10 shocks for now,

I now have 3 trucks with winches. made a new electronics tray for the Ford. Only had plywood on hand, but it works.
I wired up an ESC to power the servo. So there is no drift. I used the Traxxas XL5, but it has no drag brake, so the line un-spools when no power is applied. I'll probably switch it out for a Castle sidewinder. With 200% crawler drag brake.

Edit: The Sidewinder is much better. I'm getting psyched for the hands free run!

I've been working on the trials truck.
So far I have all 4 axles mounted to the chassis.
I need to do some suspension R&D to make the front and rear axles stop their massive amounts of torque twist(the rear will twist far enough for it's pinion to point straight up!!!), but otherwise it's a rolling chassis at this point.
I need to swap the rear axle to underdrive gears to match the rear intermediate axle.
Transmission mounting is also among the things on my to do list.
Trying to decide whether to have just the 2 front axles steer, or if I will do 4 axle steering.
Both have their pros and cons.... Hahahaha!!

Im guessing that rig is about 2' long!

Nice use of a level!!

Looks good Rob. What you gonna use to power it?

Thanks bud!!
I'm going to use the trans & 55 turn from the Power Wagon, though I'm going to put an 8 tooth pinion on it.
I'm contemplating stealing the HPI crawl box out of the King Hauler to give an extra 7.4:1 of crawl.
Do I hear the sound of snapping drive shafts? I think maybe!! LOL:lmao:

 

[Haulingram82]

Ordered the body for project mini me. Have to find some 1.9 bfg all terrains next.

That's awesome!
I'd love to do that, except no one makes a ZJ body. :-(
There is a YJ body, but it's a hard shell. I'd destroy that within an hour.... Hahaha!
Can't wait to see it finished!

So, I've run into several engineering problems on the trials truck.
The suspension for both the front and rear intermediate axles is fine, they are basically stock dimensions, but at slightly different angles.



The front and rear axles, however, pose a unique challenge.

The lower control arms connect to the intermediate axle so the control arms run horizontal, while the uppers connect to the chassis.



This limits the free movement of the intermediate axle in the sense that the front suspension won't compress without forcing the intermediate axle's suspension compress as well.



The front axle can droop completely while the intermediate axle can compress fully, but not vice versa.



I wanted to have the front & rear axles to have their lowers mounted like the intermediates do, but I cannot come up with a drive shaft that will compress to 1/2" and extend to 2.75", so the lowers must connect to their intermediate axle.

Now, on to the matter of the torque twist from the front & rear axles...
If I bring the upper control arms down to the intermediate axle(where the lowers are mounted) it will totally eliminate the torque twist, it will also allow the front axle to compress more while letting the intermediate axle droop more.
BUT..... that puts me back to needing a magically telescoping drive shaft...

So I need to figure that one out.
Maybe some brackets to lower the upper control arms while still attaching them to the chassis.

Next issue.....

The transmission doesn't fit between the frame rails in stock configuration....



So I came up with a plan!!!
I modified a spare transmission so it can have a drive shaft hooked to it.
My plan is to maybe borrow the 3 speed transmission from the King Hauler and connect it to the modded trans.



Then I would have 3 speeds, "slow", "mega slow", and "snails will pass me"!
LOL:lmao:

Just dropped $120 at RPP Hobby. Bought some new rubber, foam, and a few decals.
Hopefully by weeks end I'll have new Voodoo U4 tires mounted up and on the Deadbolt wroncho.

 

[robertjpjr]

Got the goods. I need to get shorter shocks though. Wraith shocks sit a bit too tall for my liking.

Dang those look nice. I'm torn between trying the voodoo klr's or pitbull rock beasts.
