Project RockClod

yea! sure didnt take me fuck all to get it this far!
just need those 3-link post mounts and shes a roller chassis!

Needs:

hs645mg servo
Rx/Tx (have lotsa that shit, just gotta muster them up)
x2 55T motors
links for steering
mount for steering servo

still debating on stock savage shocks for maximum articulation, i love these alloy piggys but.....

looking like a truck now ... coold deal ..

now after installing the body, im happy with the articulation.
the tires come right up to my custom wheel-well cuts perfectly
while holding the 3-links where they approx should be (still no mounts up top yet )

still gets some sweet twisty too it!

looking at my custom lower link mounts, heres how they look
and are installed.



Chassis/Articulation



With body:

: clod looks sweet dont she....

Update:

Steering links figured out...
ill be using the standard clod-links for the steering aswel as the bellcrank so i dont strip the servo gears. Don't car for those clunky kimbrough's.

Ill be using an Axial scx10/Ax10 servoplate directly on top of the transmission, connected to the bellcrank.

*3-link postmounts as shown are not in place yet*
*Custom lower steering bar not yet made, ill keep it there until i get this all setup & working*

servo mounts up pretty sweeeeeeeeet!!!
and this aint moving a bit

, but I can tell ya from experience th gearcase will break right off where is mounted, and the plastic bellcrank will not last long either so far

the mount i fabb'd bolts straight through the transcase in 2 spots, it aint movin. as for the bellcrank....that i know wont last long so i was thinkin on researchin an alloy one for these clods.

I know the mount is sturdy is the plastic case is where it will tear off of, I know i have done it far as some bellcranks go you need something like these Sassy Chassis bellcranks .... or ones like i have on Firestorm from JPS Products... them are billet ones and stout as all hell

these are Sassy Chassis stuff from the 90's here VVVVVV






and no ya can't have / buy / steal em either

took a long time but got the front end DONE like es
3-link post mounts are part of the custom steering plate ontop of the chassis.

Need a lil better/clearer cant see much on the servo and link mount there , looks like it outta steer good tho.

heres a closer shot, but my cellphone doesnt take the best once the sunlight goes down

ya outta invest in a decent camera to take , but I can a lil better in that one

stayed up working on some stuff, worked out a few glitches along the way but came across a new one near the end around 1:30am

i got my rear 3-link's made up and installed but made them too short hence the rear collapsing on itself.

now i need to redo the rear 3-links'
thats what ya get when your fuckin tired as hell, oh well

replaced the shox using Savage type as the alloy piggybacks were makin contact to the leads on articulation.

TwIsTy

hard at it again today!
this rig is so close it almost ready for its 1st test run now!

Left to do:
----------

desolder the 18g wires off the mayhems & solder onto 27t 540SH motors.

install an antenae tube onto custom mount off TVP chassis

*Note:
Futaba servo which is installed temporarily (which is weak)and I know steering will suffer greatly from it, until i can afford a HiTec hs645mg. But it's for testing grounds anyhow, so... stay tuned in the next day or two for the first vid of this beast roll. Ive already tested the esc/motors/rx/tx and it functions fine.

make sure ya get a vid to go with ur test session.

I just had to fuckin do it!

UPDATE:

Now i have the motors wired up using Deans connectors and
everything there works fine but the steering servo (Futaba S3003) is a heaping pile of SHIT!

it virtually has no power to turn these goliath tires from left to right.
at first i thought maybe the links were tight or such, so i popped the link directly off the servo and manually turned my wheels. That didnt seem so bad but i sprayed it with HD silicone spray and free'd it up a bit. Slapped the servo link back on and again....useless as tits on a horse!! fuck! now i need a HiTec hs645mg to push these tires around.

Testing it out in the garage with littelry no steering, the thing moves considerably well except i get motor stall on either front or rear depending which ones grab traction first. is there a way around motor stall? i remember reading this on these clods somewhere but dont recall where or what??

next, i hit a block at minimal speed (basically just a bump) and bent my custom link from the knuckle to the bellcrank. Ill beef that one up, but will have to make a skidplate up front to eliminate this issue.

This 3mm threadrod & 3/16 alloy tubing got trashed from a very light hit! :P
Too soft of materials, so ill need to beef these up with somethin different!


next up...im putting limiters in the shocks to bring the ride height down a touch as it sits too high imo. but the articulation is bang-on and the transisiton is very smooth. So in a nutshell, i almost have it right minus a few glitches.

still not vid-ready but close! :D

After dropping in shock limiters to bring the ride height down i decided to cut the box off the lexan chevy!

Installed my AX-2 metalgear servo and atleast my steering worx!!! cranked the bellcrank right down for now to maximize the steering.

540sh motors arent the low Tq i need, the servo was the ONLY thing that got warm after running it

With the pitch on these clods, whats a good pinion for way-down Tq?

mocked up to make sure everything fits right, its a go!
but....i gotta run to work, more to come!!

Sweet looking clod swamp,they almost look like XF2's : close to the real thangzz ...

More progress:

RC4wd steel bumper
Axial Rockrails
Axial battery-plate/mount
Axial rear center bracing

Still left to do:

Fabricate a whole new steering assembly, i was thinking on
using the servo off the front/chassis but it may either do one of two things with it being the way it is. Either the steering link would be so long as to throw the angle off under articulation or bumpsteer. Ill have to this one out but ill use the steering as i have it for now so atleast i can drive this bitch!

Still looking for 10mm material for 3-link post mounts and will have to
play with motor/pinion combos til i get the torque down where ii need it.

Lexan body....
i used my old nitro chevy body for a donor for this project but ill be grabbing another body later on and cutting it to what i want/need to use for flatbed setup. The front/rear windows were hacked for the most part to allow air into the cab for the nitro mill.

looks good 2 me ..
