DLUX super build

[Erik D_lux]

Thanks!

Yeah, for the most part things are good. Supers are funny, it reminds me of 1:1. Everything seems to get stressed much more and I feel the need to constantly keep an eye on things.

Sidewinders are holding strong after 45t motors.

I cant seem to keep the kingpin bearings in one piece. I am going to upgrade to some bigger bearings.

It looks like I am ripping the arm off the machined knuckle. It has looked this way for a bit so I am just keeping an eye on it. Looks like its a factory defect, I think I would give them a shot again.

I was always killing those bearings on my super bullies.....especially the crappy ones from RC4WD.

The kingpin bearings or the wheel bearings?

 

[rcjunky3]

yeah kingpin bearings is not the answer on these knuckles, bearing breaks=axle pin snappage
i have done it a few times now. and i check the screws for proper tightness after each course they are shimmed properly with no binding. i think it was better off without the bearings and just stick with a bushing. the whole reason i went to a bearing was the thin thread area in the rc4wd tubes. did you ever run yours with the bushings and all the meat in the thread area that an ax10 chub has to offer.

Oh damn....nevermind. I was thinking of the knuckle bearings. I never had an issue with my Duratrax KP bearings...

Are you running 4 or 3mm kingpins?

Yeah, I started out with the stock bushing. It was not something I can accept. I guess I am not going for strength as the difference, I am going for no slop.

I am running the 3x6 bearings. I wanted to start at 3mm and have the option of 4mm however, I did find some 3x8 (I think). I am going to try those. They are not flanged is t he only problem but I am hoping they work good since the AX10 C is almost a perfect fit and should stop any up an down slop? Guess we will see.

please let us know of your findings

are you still looking at lightening your wheel set up some more...if so what are your thoughts?

 

[Erik D_lux]

Yeah, I have always wanted to change out the aluminum spacers for delrin but, I keep changing my wheel widths. I am not 100% sure on the width I like but when I figure it out, I will make some spacers and expect to lose a bit of weight.

Wheel width makes extremely drastic changes on these cars, even 1/8 is making a difference so, I need to figure out where I want to be first.

As soon as I get more CF I will be making some faces for the wheels too. I have high hopes of losing a lot of weight from just the faces.

how drastic a strength issue do you think it would be to machine some sort of pattern into the faces on your wheels....they look good now, but I thought I saw a post somewhere someone asked if you were thinking of maybe machining some holes or whatnot into the faces? Not having ever seen them personally.....8)

 

[Erik D_lux]

When I did designs into the 1/8" delrin faces on the 2.2's they lasted awhile but eventually failed. 1.9's have never failed with designs in their 1/8" faces.

I really expected the 1/8" faces on the super to fail even as solid pieces with no design. They have held up great but I dont think you could push it any further by drilling holes unless maybe you did some around the beadlock holes.

I think CF is the answer since I will be going half the thickness of the material PLUS a cut out. If I am wrong, it will be an expensive mistake.

Any updates?

 

[Erik D_lux]

Nothing significant enough to post. Just doing lots of tuning and trying to get this car to work to my liking.

 

[Erik D_lux]

I have been slacking on this thread and slacking on this car (driving and tuning) in general. I have been putting a lot of time into my 2.2 but, now I feel like its where I want it so I am going to try and get this car where I like before PCC in a couple weeks.

I have made some significant changes to the shocks and shock mounting to try and get the ride height down. I like my front shocks laid down quite a bit so everything just took care of itself on that end since laying them down will also decrease the ride height. On the rear, I first took off the taller shock mounts and put some of my 2.2 mounts on. That brought the height down quite a bit. Then I went to a 3.75 long shock with the short, standard rod end on the bottom and then some of my Dlux shock ends for the top. This is where I am at with it right now. I think its pretty good.

At the last comp I did a back flip from 7 or so feet and landed straight on the nose. This ended up breaking my chassis at the lower link mounts. No biggie, just a great reason to use some better carbon and also do some changes that I wanted done. "thumbsup"

The link changes I made in the chassis along with the shock mods (above post) really did wonders for this car. I have never been too happy with the handling, it has always felt like the axles and tires just flop around like an infant throwing a fit. Today was the first time it actually felt good to drive. That is very encouraging after fighting several issues and not knowing where it comes from, shocks, link geo, tire/foam etc,.

I do feel like I am still getting more hop than I should out of the rear end, I am 99% sure at this point that it is not the link geo or shocks but it looks like the tire/foam. The hop only happens on low traction rock, the car seems just find on rock with better traction.

I have been running a full uncut boss claw to try and reduce this hop but it just is not helping. I am running the closed cell foam setup in it but I am going to put a post in the wanted ads to see if anybody has an older Nova non closed cell foam that I could try. I wish there were more foam options for supers.

A couple shots of the new chassis.

This really is a good looking super."thumbsup" Keep up the good work.

very cool design"thumbsup"

Thanks "thumbsup"

I also forgot to add that I switched out the kingpin bearings to a 8x3 and have not had an issue for the first time.
