WK SW2 Build

[clarkrw3]

I have been working on getting parts together for this build for a while. I have hit a snag however because I changed my mind on the lower link mount after mock up and ordering the links so I need shorter lower links to make the angle of the axles right and still at 12.5" I will be a little under 11.5" wide with these wheels. Here is a list of parts I am using and some pics...let me know what you think"thumbsup"

Sw2 chassis
WK axles with Hardened gears in the diffs (Which gives you 5mm outputs)
Locked diffs with JB
R2 trans
WK shocks
Hypersion 3013
Mamba Max
Towerpro servos
RC4WD wheels
Moabs
M8 radio
Spectrum rec
Tlt upper link mount
Extreme Rc links High clearance
Tmaxx shafts 5mm output
Bushwacker body
Home made steering links

looks like a good start

Pretty slick. "thumbsup"

How do the upper link mounts on the axles feel? Any flex in the mount?

They are very solid... no flex at all. The WK mount has three screws holding it to the axle and the TLT mount has two screws holding it to the WK mount. No modding was needed for the TLT to match up with the WK mount"thumbsup"
the four link in this set up actually limits travel compared to the stock 3 link, which I think is good in the application. Stock WK's have more travel than most want for a comp crawler anyway. With this set up and rotating the lower links 90deg you will end up with all 4 links the same length at 4.5" which is optimal...IMO

How did the servo mount come out? Much trimming?

[clarkrw3]

Some extra trimming around the pumpkin, as you can see the tab for the screw next to the wheel isn't far enough to screw into. If I do another one I would beef out the tabs that go down next to the pumpkin so they aren't so thin. Thanks for all your work on this. I would, however, buy one if someone made one that was more finished then mine. I am going to do rear steer so I will need anther one at some point.

I will make those adjustments, when did you get a copy from me? I think I did extend the tab.

Would you be willing to cut out a new template and just hold the paper up to the one you made to see if it is an older version?

The more people who try the better, thanks.

Clark, The long shaft coming out of the tranny looks to go thru a carrier. If so where did you get it or what is it made from. Also does that long shaft come with the tranny. By the way looking good."thumbsup"

[clarkrw3]

Those "carriers" are made by RC4WD and are just to adapt the 5mm shaft to 6mm so that you can easily run the Revo shafts. The long shaft comes standard with the tranny but you can get an optional short one if you want.
thanks for the kind words:-P

[clarkrw3]

Got new lower links coming from JP that sent out yesterday so hopefully I can have this thing running by the end of this week"thumbsup""thumbsup"

how wide are you with the rc4wd rims and tire together on the w/k axles

[clarkrw3]

Just under 11.5" wide as it sits."thumbsup"how wide are you with the rc4wd rims and tire together on the w/k axles

[theTman]

won't the steering linkage in the front hang up on the rocks. it angles outward, not to mention that they are plastic. do you have plans for steering linkages?

[clarkrw3]

I do have some delrin links for the front, and yes rear steer would be nice and once someone makes a rear steer kit I will pick one up for sure.....waiting vendors!!!

[Harley0706]

What kind of rear steer kit are you looking for?

[clarkrw3]

What you came up with is great!!! I just want someone to make it for me. I just don't have time for the fabrication right now, I just have too many things going on and I would love to get this thing buttoned up with machined parts."thumbsup""thumbsup"

What kind of rear steer kit are you looking for?

[clarkrw3]

Ok...I am almost done. I still need to paint up the body and work on my rear steer. (which is allowed in PARC). The new template for the servo mount worked like a charm, and with 0.06 Al and tin snips in made drumal work much better. I also fabbed up a battery mount using the knuckle screw and two screws in the mount for the original steering link, which came out much better then expected and very solid.

My real question is this. I am going to be running 1500 cells in a brick pack on the axle, should I go with 6,7, or 8 cells? I am running a 3013 with Mamba Max. Also I am wonderering about final crawl ratio. The axles are 2.93:1 and my R2 is 30:1 so that gives about a 90:1 which I am sure is too high? I know that for supers you want it around 50-60:1 but am not sure what it should be for the 2.2 rigs. I have been searching but haven't found what I am looking for.

I will post pics soon it has come out great so far!!"thumbsup":twisted:

[clarkrw3]

Here are the promised pictures.

Let me know what you think;-)

This is my version of a battery mount and servo mount using the famous template that works great now!!"thumbsup"http://im1.shutterfly.com/procserv/47b7da05b3127cce83300482cddd00000016108BZsmrlm4bq

These are custom steering links the lower is made out of 8-32 rod and revo HD rod ends the top is a modifed link from Extreme RC delrin.

[clarkrw3]

I just ordered the battery packs from Holmes Hobbies for the rig and went with 2/3A Elite 1500 cells and 8 cell packs which should give me some punch. I also ordered a 13 tooth pinion which should give more wheel speed than the stock 8 tooth but still give me around a 60:1 crawl ratio. Once those things get here I will be ready to wheel with it and then rear steer set up... I am liking the way it is turning out. I have a bushwacker body for it and I think I am going to go with red and white.

[clarkrw3]

I have it running now:lol: Pretty impressed with the initial shack down. I might change from the 8 tooth pinion I am running now but it crawls crazy well now. I need a longer servo arm in the front to get a little more steering. I will be installing rear steer and mounting the body. I have a Bushwacker that I am painting red and white but need some more white paint. The battery pack works great and is very secure without the zip tie. John from Holmes Hobbies hooked me up with the sweet battery pack"thumbsup""thumbsup" I think it came out great now have to see how it does in comps;-)

Now I just have to figure out how to keep my beads in my RC4WD beadlock wheels.

[Roadbiker3]

Is there a web-site I can get those lower links @, I tried searching but came up empty handed.

[clarkrw3]

I got a set of links from Xtreme hobby rc and one of the upper links broke running the first battery through. My lower links came from this JWCustomWerks http://www.rccrawler.com/forum/showthread.php?t=64351&highlight=delrin+links
with Revo HD rod ends. They seem to be of better quality and haven't given me troubles yet."thumbsup"

Nice to see someone is looking at this thread. I will post update pics soon!!

[tltman12]

sweet"thumbsup" that things pretty long:lol:

[Cslax06]

Do you have a part number for that tamiya upper braket that you used on your upper links?

[clarkrw3]

Part #9804179

for just the brackets, or

Part #9444386

for brackets with out drive axle parts. I bought the second one because everyone was out of the cheap one.

[Roadbiker3]

is there any way that you could post a pic or explain how you mounted the shock and lower mount to the axle. I tried rotating the stock link position so that I could use the lower hole for the link and the top mount for the shock but the 2 would not fit in that spot together. Any ideas would be great.

thanks,
jim

[clarkrw3]

i will try and get a pic but you need to put the two holes to the back of the axle and use the lower for the link and the outside of the upper for the shock with a 3mm bolt going through both holes in the bracket....

[Roadbiker3]

Yes i did move the mount around the axle but I was gonna put the shock inside the mount and mount the links to the side of the mount closest to the driveshaft. It seems like it will work that way but i will find out tonight when I get off work.

[Roadbiker3]

do you know the length of your lower links eyelet to eyelet, for some reason mine look very long and the way that it is setup my lower links are parallel to the ground

[clarkrw3]

I don't remember off the top of my head but I am pretty sure all my links are the same length, the lowers are just high clearance. 4.25 sounds right but I would have to measure. Some or ride height is due to the shock length and not just the links. I ended up being a little long, a touch over 12.5" I don't plan on changing it unless the guys in PARC complain.
