F150 Wheely King

[kdubb88]

Here is my first atempt at building a crawler. I picked the wheely king for the look of the axles. What I did not realize is the challenge of mounting these axles and gaining ground clearance. I made many attemps at custom brackets and after about 4 tries I ended up with this. I fliped the stock clamps upside down and sut off the tabs (old shock tabs). I cut out some sheet metal and drilled and bent them to fit on the axle straps. This put the lower link mounts on the inside of the axle housing. This seemd to be good except the drive shaft u-joint was below the lower links. I made a slight bend in the lower links to help protect the shafts. I liked the WK upper triangulated links so I made some custom ones. I fought the steering servo mount as most people are. I used some sheet metal again and created a mount that bolts the shock mounts. Seems to work pretty good. I found that the REVO shafts worked almost perfect for the new drive shafts, just a small amount of shaving to make the fit. I locked the diff's by filing out the two inner gears holes to a square shape and using some 1/8" solid sqaure stock. Worked great with some extra filing of the shaft ends to fit into the cups.
It took about 4 attempts to get it this far. Alot of trial and error.

Here it is
WK axles - locked
WK trans - 96 spur - 21 pinion
WK shocks - 70 weight oil
55 turn motor
LRP ESC
2.2 MOAB's
HPI Spike wheels
Proline F150 body

Sweeeeeeeeet

Wow that looks awesome. How did you mount the tranny?

Thanks!

I used the stock holes with the WK screws. I used the WK stock chassis as a template to drill out the new chassis.

Can you take a pic of the front axle and servo mount area from the front. I would like to have a better look. Interesting? Also does the battery move back into the motor as the front axle raises/shocks compress at same time. Seems it would push motor/servo some as I see no extra space. Nice truck "thumbsup"

[xjwalt666]

it almost looks like it would just slide in underneath the motor. seems like it is just at the right height and that as the front end goes up the back side of the batt pack would angle down a little more also to allow for more clearence. can you see what im saying?

[neverupright]

Sweet rig! Love the new ideas for suspension mounts. "thumbsup" I like the body size too.

[FrankyRizzo]

You need bigger pics.

Can't quite see the molecular content of the screws.

ROFLMAO^^^^:lol:

The battery sits on a plate with the end bent up so it clears the backside of the servo. It is tight, but, clear. The other end is clear from the gear box. The wire may rub some. When the suspension goes through the full motion, there is no binding. The battery does not move much because of the velcro patch. No problems yet.?

Take a look.

I removed the side of the chassis so you can see that it is on a simple pivot. Also, the other end of the batttery tray is bent at 90 degrees to keep the battery from bumping the back of the servo.

There is room for the wire leads when the battery is installed.

The front of the battery has some clearance.

Here is the servo mount. It leaves room to get to the upper link axle screw.

I appreciate your comments. Thanks

Sorry, The next ones are better.:lol:

That is awesome, Nice fab work! I am definitely building a WK axle machine next. I just can't decide if I want it to be a crawler or a trail/mud rig.

I am just about ready to start another build. I am planning on using WK axles for a trail rig. I might even attempt leaf springs.

Thanks for the comments.:D

[gopher]

Great build! the WK looks like a lot of fun...

I want to make a trail rig for my son out of a WK... just need him to pass a "test" and my wife to not pay attention to the bank account... rofl!

[kdubb88]

I got my first chance to take it out and test. Nothing broke, but it could use a little more torque. I might have to try and add a little weight to the front to get a some bite out of the front tires.

that is a nice build. hopefully, i will get me a wk soon;)

Nice job on the frame, I'm going to use Reign Products K2-3S http://www.rcpcrawlers.com/chassis.htmlframe when I get my WK and some money for that matter. I really like the scale look of the wheel/tire/body combo

[NickRummy]

wow that track width looks wide! I never payed attention to it on my WK. Maybe its because your body sits lower.

Looks killer!

[JIA's Dad]

Kdubb88, Nice truck!!! I like the servo mount being different. I was concerned about the battery pack riding back into the motor area when both front shocks compressed as in a drop or fall. But looks like there is room. What's it like on a side angle with the battery and motor that high. COG? Any problems rolling over. Also 4oz. of #8 plastic beads helps fill the tires and slows side wall rollover. Also helps COG. Still a very nice rig"thumbsup"

Thanks for the frame link. I just received my 4x4 WK today and I am thinking of making a leafer. That frame might work out good with the body I am going to use."thumbsup"

The HPI spike rims have a little bit more of an offset than the stock WK rims. It helps with the wheel/body clearance under flex.

I know you can not tell much from this photo, but it wasn't long before it tumbled over. (might of had something to do with the drop off) I did notice that the COG is decent if I can keep the wheel speed down (crawl'in). Under full compression and giving it throttle on any type of decent side angle, I can get it to tip, but not roll. I think it could use some stiffer springs and lowering the COG can hurt. The suspension seems snappy. It is running about half droop. I did not notice very much side wall rollover. I did not use the talked about star cut n the foams, I just shaved them down about a 1/3rd.

A burp of the throttle, pushed it over on this one.
