my HPI crawler king transformation

[allanon1965]

Hi all, I am new here and have been following a few of the threads, especially the ultimate crawler king thread. I have a crawler king I am beginning to upgrade and so far I have converted it to the over axle steering servo. I also added headlights and taillights connected to the bat connector on the esc, makes for fun nighttime crawls

I am also converting it to 4 wheel steering and a few other tings I am researching. I will be using this to gain a better understanding of crawling and this project provides for a relatively inexpensive way to do trial and error mods. Thanks for reading this and here are a few pics.

this is bone stock the day I got it

with headlights added

Tail lights

This is the front steering mod which greatly improves steering, with a better servo and the mounting bracket for the axle

it looks as if i will need a reversing servo y-cable for the rear cable, i got one on order, i could have done the solder trick switching to wires on the circuit board, but for 8 bucks, its not worth it to me.

 

[allanon1965]

well the rear steering parts are on the way, but I am wondering if dual shocks on each wheel would benefit me in any way, its easy to do, no mods needed...

got a highly modded crawler king and the 4 wheel steer was a good one. reducee box and 21t motor works good. i broke axle gears and got hardend ones. traxxis driveshafts work

The dual shocks looks sweet, powerwheels motors all the way home for me

 

[anthonyjlc]

Looks good

here is the latest update, the rear steering works, but i am still waiting on the traxxas servo to match the front so they turn at the same rate...right now I have left turn but not right....

 

[anthonyjlc]

Why cant you turn right??

 

[allanon1965]

well the original servo turns at a different rate than the traxxas, and when I try to center it it wont stay centered, it goes left or right..so I think when I get the matching traxxas servo it will work as it should..

 

[anthonyjlc]

Hpi servos suck

 

[allanon1965]

well the traxxas one will be here in a couple days...got it cheap online...

 

[allanon1965]

well the traxxas servo finall arrived and it works great!

Right turn clyde!

Left turn clyde!

 

[allanon1965]

now waiting on the shock mounting hardware so I can mount the second set of shocks!

the second shocks are cool looking, but a bandaid imho. Every stock WK or CK shock I've ever had was a pos and leaked from the get-go. Rather than doubling a turd, invest in a good set and I think you'd be surprised how much better it works/happier you are... but, that's just me, I will say, it is different and adds to the "monster" truck theme and "coolness" factor


regardless, I am stoked to see someone excited about building these things, they seem to be obsolete, but with some creativity, they are pretty f-ing fun for the buck.

Nice looking rig. Mine should be deliver on Monday....Cant wait!!

 

[anthonyjlc]

Crawler kings are awesome, with an imagination you can do anything

 

[allanon1965]

well the second set of shocks was to make sure the concept will work, and work out the placement issues without spending a small fortune, if it works as I hope, I will invest in some much better shocks for sure!

 

[anthonyjlc]

Better, aluminum , shorter shocks are one ebay dirt cheap

 

[allanon1965]

dual front shocks are in!

so are the rears! the torque twist is gone and it seems to work pretty well, I will tweak it in the days to come, but for now its pretty good!

 

[allanon1965]

well, took it out today and ran for awhile in the cold and snow...ended up breaking the original plastic servo-saver arm. I replaced it with an aluminum arm and we will see how long the servo lasts!

it runs really well now with the rear steering conversion and the dual shocks, but I will replace the originals with something better (shocks)

I cant beleive how tight a circle it turns now! about 24 inches in diameter! before it was over 8 ft!
