RcBros 2017 Spider Build

but don't understand that i nerver seen them in other build thread???
?

Cause I have sources to find those rare unicorn parts :lmao:

Anyone guess by the picture below what I forgot to order?

Assembled, now time to cut them up :mrgreen:

I wanted to use Vanquish's VXD axles on this build. VP is kind enough to sell the pieces to order just the longs, and frankly with a dremel and some patience the mod is very easy.

I didn't use any measuring devices here other then my eyeball. I installed the assembled long shaft into the VP Chubs and Knuckle.

I then pulled the back axle half off leaving the burly tubes installed. Then I lined the chub up with the inner portion of the burly tube splines and marked where I thought the shaft would need cut.

Using the dremel I cut the shaft to length. Then with alot of patience, I tried my best to evenly grind down to flats on the shaft. I was able to get a very snug fit into the incision locker.

If you can use a dremel, you can do this mod.

I don't know where the heat treat is at on these, but I did take care to ensure the shaft didn't get very hot. I'm pretty confident these should last. Time will tell.
 
It's really been fun tinkering on this rig and getting back to the route of why I originally loved this hobby. No fancy tools, no big wallet, just a clean fun sporty build.

I've had a stock pile of VP Ti links here for some time, it made suspension mock up extremely easily. I think I'm just a hair over legal length currently, but I do plan to bend the lower links so things will change.

I needed to mock the suspension up so I could finish up the electronics.

Just curious. How does doing this affect the performance or predictably if the suspension?

Depends on alot of variables, such as how much its spaced off on the chassis, how far laid back the shock is etc...

I had this setup on the old build and it worked well for me.
 
Cut up a new electronics mount to go in between the front link mounts.

Holmes BR Mini, Castle BEC and FrSky TFR4-B receiver.

Soldered everything together and then bound to the radio.

I prefer to cut all my ESC, BEC, and servo wires and recrimp new ends on them. Its easy and quick to do if you have the right tool.

You'll need the following:
JST-SH Connector Crimping Tool

JST-SH Servo Plug Set

Now that I have everything shortened and mock up complete, everything will get conformal coated.

Electronics have been conformal coated and heat shrunk on to my mount. CF does conduct electricity, so I may sure to install 3M double sided foam on the bottom side of electronics.

Tom-foolery came over and nailed out the rear links.

He has this killer ebay Tailan tube bender which allows you to bend two links at one time.

All the links used are from VP, no custom mods other then the two rear bends.

Rear Lower Links: 3/16 X 115MM
Rear Upper Links: 3/16 X 105MM
Front Lower Links: 3/16 X 95MM
Front Upper Links: 3/16 X 85MM

I really like the way you did your electronics very clean. The links looks great.

I will be ordering me one of those benders. Being able to bend 2 links at once would save alot of time and material.

I have been trying to find bender like that. I can't find that kind on ebay or everywhere else.
 
Took me awhile to figure out where the BEC was. Thats my next project on my XR is to clean up the electronics. Plan to pick up those tools you suggested.

Such a clean build so far im loving watching the direction this build is heading👍 the electrics smash is one of the best ive seen to date so compact and on your question b4 i only could see 1 stub axle in your vp gear 😉
 
Got both VP XVD's modified and in the sporty tonight..

When tom foolery was over, we decided to try the stock Axial servo mounts, keeping the servo as in as possible to protect it from some beating.

You'll also see the small blue o-rings installed on the bottom side of the tie rod. This helps keep the tie rod from flopping down. The tie-rod comes from RC 4x4 stainless who makes a great tie-rod for our XR10 width burly tubes. I usually have these in stock.

The drag link is a different story and does require some custom bending. Sourdojack was able to find a use one I had, and make some adjustment bends to make it work. Full steering lock to lock with no interference.

Our comp is Sunday, but i'm close!
 
Hope someone shoots some video of this rig in action..
Those front knuckles look to be extremely laidback, but I do like the BTA tierod. Good luck Sunday Will.
