- RC10 Graphite: a runner with long printed arms -

[Asso_man!]

Hi folks,

Thought I would share my latest runner project on which I ce been working for some months already. Collecting parts in a pandemic situation is not easy and takes even more patience than us usually.

Anyway, I started this with random parts from the stash. The Graphite chassis was a must and I also wanted to have a kinda proper 21st century RC10.

Here is where it stands at the moment:

Interesting bulkhead swap ya got there.

I have incorporated a lot of mods on this already, the main one being the use of long printed arms that retain the same design as the originals but that are 5mm longer on each side for the front ones and 10mm longer for the rears.

The wheel base is also increased by 5mm in the front arms.

This set up is made to accept rear Yokomo driveshafts (from the 870c). These are on a slow boat right now together with Yokomo rear wheel hubs.

Yeah, this is something that always bugged me on the RC10 is that you always have to use some sort of spacers somewhere to align the shocks perfectly in the right travel movement.
This mods includes cutting the battery holder and flip around the bulkhead and attach the shock tower on the back. I fabricated a quick and dirty tranny brace out of G10 that prevails me from modifying the superb shock tower!

Masami used that flipped bulkhead and tower on one of his cars.

I just happen to have a bulkhead that someone trimmed the same way. I may have to use this in a build. Nice complement of parts too.

It is all at mock up stage right now but quite advanced still.
All white parts while undergo a black Rit Dye bath ultimately.

The use of the longer a-arms also enables to use bigger front and rear shock bodies, a recurring issue with big bore shocks.
Right now I have in the 23mm bodies and 21mm shafts in the front and 31mm bodies/27.5mm shafts in the rear.

The problem is that the suspension travel is located too high (the chassis would scrape the ground in a tight turn or after a jump).
I have ordered 27.5 bodies for the front and 36 for the rear and believe this will offer the best compromise. I can then play more with internal spacers and shims to adjust the ride height.

Masami did that flipped bulkhead and tower on one of his cars. This was a reproduction of that car that I helped make the towers and brace.

I obviously and blatantly copied Masami’s trick there. That mod is also included in the original RC10GX that I bought from him!

I also wanted to flip the shorty servo and free some space in front of the battery to mount weights, receiver and ESC.
The steering design from Niki is brilliant for this and available from Shapeways.
The only mod I will bring to it is cutting the side ears and fabricate a steering rack for a better Ackerman.
I will also swap the 30 degrees front hubs for 25 degrees ones.

All ball studs, ball ends, pins, turnbuckles and upper shock mounts are titanium and made by Lunsford.

Oh poop...I’m getting forgetful in my old age lol. I knew there was one on here but forgot it was yours

I've been running that inline setup from nikki for a while on my woin and it's been up to the challenge of my limited driving skills so far.

Did you use a servo saver?

[jwscab]

Nope. Metal gear servo and I think a plastic horn. Figure the horn will go first upon catastrophe.

Looks good, I like the use of the B6 series radio gear plate, such a simple thing but makes tear down so much nicer

I can't read the logo, what stand offs are those that you are using to hold down the battery?

Nice build!
What slipper set up are you using on the stealth?

I'm tinkering with the Ackermann as well.
The first rack I did, I just copied the Ackermann offset from the "worlds bell crank". I was mainly focusing on the bump steer.
I'll guess once driving the thing there will be tweeking of all kinds of parameters eventually.
