| my HPI crawler king transformation
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 front view 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 Last edited by allanon1965; 02-23-2013 at 01:56 PM. |

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.

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... Last edited by allanon1965; 02-18-2013 at 06:00 PM. |

| Re: my HPI crawler king transformation 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.... |

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..

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. |

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!

| Re: my HPI crawler king transformation 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! |

| Re: my HPI crawler king transformation
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! |
