My take on a 2013 Comp ready rig!

I've been into RC going on 17 years now, I've been into and out of it a lot but this time I think I've caught something serious lol! This is going to be my attempt at building a custom chassis and pretty much anything else I think I can make with the tools I have access too.

First off lets start with the axles, pretty standard stuff here:

VP cases
VP motor plates
VP c hubs
VP knuckles
VP upper link mounts
Crawling Calvin carbon steering arm
NCD carbon rear axle brace
Stock gear for now (plan to run the factory ones 'till they die and then upgrade)
RCScrewz stainless screw kit
2 bolt rear axle mod and shaved bottoms on both front and rear lower cases

I can't say enough about the quality of the VP parts, its amazing the fit and finish you get out of these! I am VERY PLEASED with all the products I've received so far.

Other parts will include:

Dlux carbon D cut wheels (carbon rear rings and .780 spacers with all stainless hardware)
Losi Boss Claw tires shaved and sipped with CI foams
Traxxas Big Bore shocks and Losi Mini-T springs with JD spring cups (plan on doing the shock cap mod and lathing the bodies down as well)

Lower links will be 3/16 6AL4V Ti and uppers will be .125 carbon rod. Steering links are already complete, just waiting on the balls to show up. I ordered both Ti and Aluminum balls, I'll more than likely run the Ti ones unless the Aluminum ones are a lot lighter.

Turned out pretty light, I'll see how much the balls add and give you a final weight hopefully this weekend.

Ok now the good part :twisted:

The chassis is cut out of Quasi-isotropic twill weave CF from Dragonplate.com. AMAZING quality stuff, very nice mat finish and the twill weave makes it look sick IMO. I cut it using a combination of Bandsaw, Coping saw and a dremel lol, its not CNC quality but it will work, and if it works well enough I'll get a few cut on a CNC! The cross braces are .250 Delrin and the shock standoffs are actually Align Trex 600 cross braces I had laying around lol. The braces at the front are made just like my uppers are going to be, .125 carbon rod with traxxas rod ends, glued with 30 minute epoxy and pinned.

It measures 8.375 long, 3.125 high and 3.25 wide with the shocks installed!

It came out pretty light, this is with 4 steel balls and all stainless hardware!

I just got my Dlux wheels and shocks in the mail today, so I'll be shaving tires and working on shocks this weekend, and hopefully get some links done so you can see the final setup! Let me know what yall think!

I am waiting to see the rest of the build. Looks like an interesting start thus far and I can't wait to see where it goes from here. Keep the update coming as I am now paying close attention.
 
I like where your head is at and where it's heading! Where are you planning to mount the electronics? All on the front axle?

Have you read the rules to see if this is comp compliant? I haven't so I have no idea. Just asking in advance!

Keep it up , looks BA!"thumbsup"

she looks sexy.. im liking this so far...
i know nothing about comp rigs..
but i see you favor a vendor!!! :lmao:

seriously i wanted to subscribe but i cant seem to shut the up!!!!"thumbsup"
 
I'm igging the profile of that chassis but am wprried you mayh have some durability and flex issues with such long standoffs for the shocks. Very cool concept nonetheless"thumbsup"

Yes it is legal by measurements at the moment, and as long as I can make all the body panels over 3.5 sq in each its completely legal! I was thinking about electrionics the other day lol, I was kinda thinking a decased FXR or Sidewinder on each side of the plate under the side panels? or maybe all go on the axles lol

TheSCorpionKing: It was really flexible before the 2 front braces but I was actually suprised at how stiff they made it, if I have any durability problems I may try an 1/8 inch main plate vs the 1/16 one! Hopefully its ok like it is lol to keep it light.

Thanks for the kind words guys, I'll try and get some crap done if I can get out of work this weekend! ><

Now that's some Saaweeet custom work there! Very sexy CF!

With a motor/electronics mount, you shouldn't have to have anything in/on the chassis, other then the rest motor wires running thru it.

Can't wait to see where thus goes, keep up the killer work
 
it looks great ...we had a club member working on something like this a couple years back
I think the flex-spring action will be hard to control ..but why not try it...the concept is great
 
I meant to ask earlier, where are you getting Ti balls for Traxxas rod ends from?

I got then off AxialJeepster in the classifieds, great guy to deal with btw, fast shipping! Got them last night. They are 1 gram lighter per 4 than the chrome ones, should have a comparison between all 3 tonight if my CKRC order come today!

Jake
 
I'm really not sure what brand the balls are, but they were only $20 so I got them! I'm going to use them on the steering, shocks and lower links, and use the Aluminum ones on the uppers and chassis braces. Anywho here is a small update with the weights as promised:

Stock Chrome:

Titanium:

Aluminum:

The Aluminum are a good bit lighter than the Ti still but I feel better about using the Ti in the high stress areas in the suspension lol.

Also got my steering setup with my links, Ti balls and a 7950 with **** servo clamps:

I'm really happy with the link geometry the way it is, pretty much a straight shot to all the connection points (this is my Heli OCD kicking in hard here lol) but I'm not sure how the link being on the front of the horn is going to work out. I'll test it the way it is and if it needs attention I'll change it then.

Last but not least the chassis got aluminum balls on the braces and aluminum hardware! :twisted:

I finally have a weekend off so hopefully I can get my link made, or at least my lowers! I'll post up some pics when I finish them!

Thanks,
Jake
 
Well, I did get a bunch done today! But I have some bad news lol, I think TheSCorpionKing was right, its a little flexy ><. I need to find someone on the forum that can cut the design out with a CNC and I'm just going to double the center plate.

Anyone have a CNC or know someone who would be willing to cut it out? I have the design drawn up in AutoCAD 2013 and I'm going to order the CF tomorrow!

Jake
 
And if that ends up not working out, you can always build a "traditional" rig since you'll have the two side plates...Have you thought about a little thicker cf for the center plate though?
