So I started another sporty.....

Saved some parts from the winter slim down.

My entry into this hobby was a RTR Wraith turned sporty, I had alot of fun making the conversion & fell for the class. I knew another 2.2s was in my future.
I felt like I fought the AR60 axles most of the time so I decided to go with AX10 / SCX10 axles.
I picked up some axles & a tranny. Axles have steel beef tubes & axial high steer knuckles up front.
Tranny already was halfway to "all Traxxassed up," so I finished with some emaxx yokes & shafts.

Slipper Clutch Assembly

Slipper Pressure Plate and Hub Aluminum Alloy (Part # TRA5556)
Steel Disc with Friction Pads, Spring & Retainer Nut (Part # TRA5552)
Spur Gear 54T 0.8 Metric Pitch (Part # TRA3956)
5x11x4mm Ball Bearing (Part # TRA5116)
Three (3) Cap Head Machine Screws (Part # TRA2554)
Two (2) Button Head Machine Screws (Part # TRA2577)
I use the TRA4928x Yokes & the TRA4951 long shafts cut to length
I also made a rear 4 link mount out of a servo mount plate.

The axles with these wheels & tires have about a 10" width track so I am figuring a 11" wheel base is a good place to start.

Thats a start.
Picked up some (what I believe are ) Stock ax10 chassis sides (now I need a skid:roll:.)
I have shocks but I think they will need to look like this.

So much time tinkering.
I picked up some Traxxass parts
# 5319 Steel pushrods for lower links
# 5525 revo links & balls
# 1942 jato inks & balls
I also lucked into a stock East End Machine Ax10 single reverse triangulation skid plate from a LHS.


Put some new deans & a new CC BEC on a used Mamba max I picked up.

A couple set Lundsford Ti super duty plus tie rods for upper links

Body & BTH steering from skywker51 (he insisted I take plenty o parts home with me, Thanks again.)

I spent allot of time narrowing the front suspension & am almost there
12.5" Wheel base 10" wide front & rear & weighs a nice 5# 3 oz RTR

I finally dumped the axial BTA for the other one I had.
I have steering!



I also moved the rear shocks mounting point down & back a bit to get a better stance.


I am curious about this skid tho.
It has triangulation in the rear but the front is way more parallel, I assume this is done for a reason but I do not know why?
Why not just do triangulation front & rear?

I like what you've done here.

It looks very decent considering you have mostly stock, borrowed, or stolen parts on it.

Keep up the good work.
 


I took her out this morn for a bit of torture on my rocks.
I went from a square last year (12 1/2" WB with 12" track width) to 12 1/2" WB with 10" & what a difference.
Hopefully sunny weekend to break her in a bit.
I swapped the Mamba out for the ol' FXR till I can get to a castle link & hopefully smooth it out a bit.
Really happy with the Traxxas slipper. It works as a slipper should, I don't notice it till I get bound up then it slips & saves me buying parts.
The 54T 32p Spur also gives loads of room for the Maxx yokes coming out of the tranny.

This sporty is coming together really nicely!
I wish I still had my GC3-A chassis and links laying around. I would totally give it to you for your budget build! I have some XR mod tubes and plastic XR Chub's I can donate though!

OOOOOOOOOHHHHHHHHH
Tubes u got tubesss
my preciousssss
I have some stock xr chubs & knucks.
I want your tubes!
Are they the wide delrins? splined or not?

I already have beef tubes front & rear & want the width addition up front of the std xr width mod
 
I am planning on starting with stock chubs & knuckles then going to axial Al when I can afford it.
I am thinking splined is good if I am using xr chubs?
What do you think?
Back cut sounds good to me.
I guess I do need to list some stuff & get at least $40 in my paypal so I can get some XR uni's heading this way.
Feeling a lot more love this year.
Thanks

The stock plastic XR outers hold up pretty well. The main thing you want is Zero Ackerman. The easiest way is to bolt on some steering arm's that are zero ackerman, flip the knuckles side to side, and cut off the plastic arms.

Basically THIS set up. Just flipped with the tie rod behind and under the pinion.


When you can afford it, I would run VP wraith knuckles or the Dlux knuckles.
 
So in that thread it is no splines up front ( I assume for clocking to the exact angle one wants rather than choosing one of the splined slots)
& splined in the rear.
So I am thinking splined front & rear.
PM me how we can work out a way for me to get hold of your tubes.

Ya got it backwards, splined in the front, non splined in the rear. Take another look 8)

The splines are for keeping the Chub from rotating on the axle housing/tube. If you rely on screws, they tend to come loose over time. There is a lot of stress trying to rotate the Chubs when crawling. The splines were a great solution offered by Axial. The rear doesn't have any rotational force on the lock outs, so splines aren't necessary.
 
So the hacked up Aluminum mount was not a permanent fix.
I modded my rear shocks with Jato rod ends on the tops (or bottoms as I have em) to give me about 3/4" more length to get the stance better.

I also swapped wheels for some rockster 2.2 axials. These have a slightly wider offset which with these scx10 high steers & ax10 uni's helps with room & a bit of steering.
I dropped all the weight out of the front wheels & am down under 4 1/2#'s.
I think I am going to keep this setup as a backup / starter sporty for my kid & those that may need it. Sourdojack & Rcbro's sporty have given me hope to be able to put together another sporty.

I don't think I can squeeze out any more steering with this setup.
