Free WK servo mount templates
 

I was wondering if any of the vendors have a axle mounted servo mount in the works?? I have been playing around with a few ideas and angle/boxed Al but haven't found anything I love. Let's see some ideas, and hopefully some support from the vendors...after all these are going to be THE axles pretty soon in the 2.2. I just put hardened gears in mine now all we need is CVD's and mounts;);)

Check out the servo mount Jake made for King Bling.

Noticed that in the video and am planning to make something like it for the Tuber WK I have in the works. Looks solid and positioned well. Simple and functional. Also out of the way placement. I like it."thumbsup"

Im a fan of Ryan62583's mount. It looks like it would be simple to make something similar.

I am actually working on a aluminum and a carbon fiber version so stay tuned to the vendors section.It shouldnt be long."thumbsup"

when you get them done i will definatly have to get one!

Ok...now that we have our own page....lets see those parts vendors!!!!

Heres the one I made. It's similar to the one Jake built but the servo isn't angled. With the stock rims/tires it was rubbing at full lock but it clears the Moabs and narrowed stock rims. I'm still waiting on my Axials to arrive too so I'm hoping it'll clear them. I've got a better template made up but I'm still waiting for the material to build it. I like Ryans too but my battery placement interferes with the servo being dead center like that. I can't wait to see what the vendors come up with for this truck!! Hopefully we can see a chassis kit coming soon as well as the servo mounts!!

*EDIT* - Check the Page 7 for the most current thread, it can be downloaded from JIA's personal website now. Also read the thread to see what input and feedback was given, the mount transformed alot throughout the process. I have seen them, or custom versions derived from them on a lot of the builds on here. Thanks again for all the interest guys! And an even bigger thanks to NickRummy for doing the initial modeling of the axles before I had ever seen a WK in person!!!!

Back to the original thread!!!!

Wheely King Servo Mount

http://i125.photobucket.com/albums/p...gs/WKServo.jpg

http://i125.photobucket.com/albums/p...s/WKServo2.jpg

I made this up in Solidworks today at work.
The Wheely King Axles were modeled by NickRummy.
There is a bunch more stuff in the tools and procedures forum.



This is very similar to the one on the King Bling. I think it is a pretty good design, it atleast keeps the servo lower.
The Wheely King Axles were modeled by NickRummy.

This is a fairly simple barcket, most of you can fab this with a hacksaw and a dremel.

Here is a 1:1 template so you can just cut out the template trace it onto your aluminum or whatever and mount it up:

PDF Format
*Removed* Updated link on page 7
There is a limit of 5 downloads per 24 hours on xdrive unless you have your own account. So I can email you the pdf if it does not work for you. Or you can try the next day.


This is designed to have your shock mounts rotated, as you can see in the pic. There may be a little bit of trimming to part that the screw threads into on the shock mount (less then an 1/8th inch I believe).
If anyone does use it be sure to let me know if there is any clearance issues and I will Update it.

Hope it helps atleast one person.

This is not to be used for anyone to profit from!!!! Think of it as shareware not freeware (I think that is the right analogy).

Josh Thiede

P.S.
I did the stress modeling on it, and with a towerpro (chicken butt) it really should not deflect much at all if you use the aluminum plate that you get at the LHS in the little plastic bag. I don't have the bag around right now so I can't recall the gauge. I am sure someone else can specify it.

Wow thanks for the template!! Have you tried this design out yourself? It's pretty similar to the one I made and I was wondering if you had any clearance issues with the tires? I'm going to give your template a try. Hopefully tomorrow and I'll be sure to get back to you about it.

I do not own a WK, but I trust these models, Nicks models are usually spot on. I have never really found a contridiction.

I have a set of masher 2ks on hpi split 5 spokes, or geos on narrowed pede wheels, or moabs that I can put whatever.

If someone wants to see them I can post a pic.

Josh

Harley,

One thing missing (or overlooked) on that servo mount is the fact that the center line of the knuckles and the front side of the axle housing aren't parallel to one another.

Anyone that uses that template should plan on putting a bend in the mount to accommodate the difference between the knuckles and axle housing.

Hey thanks JIA.

I will plan on fixing that tomorrow morning and reposting it. I will show the bend lines and give side views so that there is no guessing. That bend should actually help any flex in the piece too.

I have no idea if anyone will even use this. But maybe it will help someone.

I never did put a drag link in the model to test that. I shouldn't have done it half assed, my bad. I will make sure to post the pics.

Josh

Remember, you don't have to match the angle of the aluminum and the knuckles, but a happy medium should suffice. Folks will no doubt run various caster angles...due in part to pinion angles.

Also be sure to keep tabs on the rear portion of the servo case in relation to the axle housing and link mounts...might need to raise the servo a hair.

If you redesign the mount with those two things factored in I think it'll come in handy to a good number of folks.

Just a thought. Since you really don't need those mounting bars on the front of the axle clamp, cut them off getting them out of the way. Then widen the lower part of that mount to reach the screw that holds the C housing on the end of axle. Now you have 3 screws holding the mount. You could do the same on the other side if you made 2 seperate mounts and that would give you a place to mount batteries on the axle. In other words 2 mounts not connected in the middle, each using 2 screws at axle pumpkin and the screw that holds the C's on the end of the axle. The battery mount would be bent to 90%. Just a thought:roll:

JIA

I don't really know why but last night I was having a hard time understanding your last post, but when I read it this morning it made all the sense in the world. I am going to fix it and see how it works. I was using a generic bluebird servo housing for clearance checks.

JIA Dad
I am pretty sure I get what you mean too, but not 100%.
As I understand:
Cut the original shock mount tabs off
Extend servo plate
screw it to the _________ <thats what I don't know for sure.

Just need a little clarification.
I definetly think it would help with some ridgidity if there was a mount over there.
I don't have my laptop open yet so maybe I will see what you mean when I do.

Josh

He was talking about mounting it to the screw on the clamp style link mount. I will be trying this soon with your template so will give you some feedback. the only problems I see with where the servo is off to the side is clearance for tires(probably not a problem) and it makes it harder to mount the battery over the servo if it is off to the side like that. One of my ideas was to mount the servo standing up useing a box peice of al, using the four screws on right or left side of the diff that face each other the distance btw the mounting surfaces of those are exactly 1" front to back on the axle...just an idea.

Ok Round 2:

I put a 15* bend in the top portion, this very closely matches the angle of the axle c's
I did have to raise the servo 0.2" but with adding the bend it will still keep the COG down
I added another support that will attach off of the screw that holds the c to the axle case, per JIA DAD.
I did not have to suggest the trimming of the shock/link mount piece except where shown in the pic.
The axle c piece will need a little bit of trimming also, but this should not cause a weak spot, you will also not have to replace the stock screw.

Of course things always work out slightly different in the real world but this may be a decent bracket for alot of people.

I will post a new template as soon as I get some feedback on this. If no other changes I will post it up ASAP.

repost once again.
Here are some more pics for reference. Sorry I was too lazy to crop them and all that jazz.

I may also be working on a BTA plate, like the one camel_rcs did on his rig. NickRummy and I are actually both working on versions.


Now the servo should match the angle - Thanks JIA for the tip.

Don't forget the original.

Harley,

Now it's time to box in the servo for strength...look at the pic Skeeno just posted.

Also, the opening for servo is a bit large.

Lots of open room under the servo. Probably forgot to go back and fix that after doing all the other stuff.

I will definetly close in the area under the servo, guess I just overlooked doing that at the time.

About boxing it in, I think it may make it hard to make. I just wonder how much deflection it would reduce, I may have to do a simulation on it to see.

I may do both, I really hope people use these. Not that I have tons and tons of hours in it but still. I can't wait for my truck though!!!!

New pics soon.

Josh Thiede

Here is the newest version. Gap was closed and top boxed.

http://i125.photobucket.com/albums/p...ervoboxed1.jpg

Let me know what you think now. I will get more photos with the servo installed, right now the wife won't get off my fawkin laptop!!!!

Josh Thiede

I made 2 seperate mounts. One for the servo (your idea of top solid is good but harder to make). The second mount for battery I should have made using 3rd screw at end of axle (same as servo mount). But I didn't (trial and error). Without the 3rd screw the mount is weak hince the zip ties. I plan to make a new one. Note the battery mount is bent at 90%.http://s160.photobucket.com/albums/t...1174495468.pbw Click the link Then go to slideshow to see photos

Looks really good...do you have a 1:1 pdf template of that ??"thumbsup"

JIA DAD

like I said in the PM, I agree it would be harder for guys to make the mount with the boxed top.

I will make sure that both are available for people to get.

As far as templates go I think it will work better if people just e-mail me with their e-mail. Just click on my name on the left and click send e-mail. I respond to e-mails very fast during the day, it is in front of my face most of the day usually. And again PLEASE NO REPRODUCTION OF THIS PART FOR COMMERCIAL USE. Don't turn this into a bad thing.

The battery tray is also a good idea, maybe I will bend something quick and post it up too if anyone wants one.

I am also working on a BTA setup, NickRummy did a model today that looked great, I am using a similar but slightly different approach.

Josh Thiede

NO just the one on my rig. But I have some scrap you can have."thumbsup"

Clark, The screws at the pumpkin are 7/8" apart and the screw at the axle C is centered between them and measures 2" to the left or right depending on which mount you want to make. I used those measurements to make mine. But I did decide to mount the servo behind the mount using the spacers that came with the servo to make clearance for the main stearing rod linking the wheels and the link that mounts to the servo arm. Other wise they were in line and hit one another. Hope this helps;-)

Since there have been no other suggestions I am calling this mount finished, atleast untill we get a couple built for test fitting. Then we'll see if improvements are needed.

Josh

I started work on making one of these yesterday but ran out of time and my cut off wheel wasn't working very well...I will revisit it today and hopefully finish it. I will post pics when done

I made one today...I will post pics. There needs to be more material around the diff screws. and using the template the length to the the knuckle isn't long enough. But otherwise"thumbsup" I think I would still buy a machined one if someone made them.

Those are pretty easy changes, Thanks you very much for the input. Can you take a picture of it for me?

Thanks again.

Josh

I will...I just haven't had the time to take the pics down load them resize them upload them and post them. O, and you have your pumpkin backwards in your diagrams. To have the servo mount on the side of the axle you show the servo would be mounted under the axle thus it has to be flipped 180 degrees to the other side of the axle....shouldn't make a difference however your drawings of the axle are upside down. look at your drawings and then look at post 20 to see what I am talking about.

I understand what you mean. Thats what happens when all you look at is a computer screen. Just like how contractors bitch at us engineers. The bends will have to be reversed then too I think then. I will look at it and fix that.
Again, Thanks you very much for your input. You are probably helping more people then you even know.

Josh Thiede

Here is the updated mount.

http://i125.photobucket.com/albums/p...ings/Servo.jpg

A BTA one coming soon, based on Camel_RCs design.

Nice work there. When's the prototype coming out?

are these gonna be available for purchase soon?

I am not a vendor, nor do I plan on making these. I am providing the template to you guys so you can make your own if you would like. These are for everyones benefit, I just do this crap for fun. There may be some vendors on here that will produce these sometime soon though.

Here is a quick snap of the BTA setup that I am working. Getting very close to. Again the basic setup is based off of Camel_RCs design. I saw a pic of it once and then just went from there. I am going to add a battery mount on the other side too.

http://i125.photobucket.com/albums/p56/jtbusa/BTA.jpg

Version 1.0

Original Concept by Camel_RCs

Let me know what you guys think. Any comments are appreciated, should be able to have a template ready whenever someone wants it. Clearances are just fine. There is some trimming required on the screws that go around the diff. That is so that you get the most steering possible.

http://i125.photobucket.com/albums/p.../BTARender.jpg

Response to the servo plates have been pretty rediculous!!!!

Thanks for all the PM's and e-mails.

I really hope we see some pictures up tomorrow.

I just threw the BTA setup it into a model with a k2 chassis to double check clearances and everything still looks good. I am sure there is something that needs to be tweaked but I can't find anything yet.
