Class 3 Capra XRmod

[MikaelBerberg]

So I initially built myself a Bomber with Wraith trans and WB for class 3 in Norway (flat rails not allowed in class 3 there), but that was way too huge and wide for that :ror:
So when I came across a Capra cage, skid and links for cheap, I jumped on that deal.

This is the first revision:
- Capra cage with InTheWorks flat skid
- Grey SCX10II 3gear transmission
- TMaxx rear driveshaft, wb8hd front
- Capra lower links with Jato rod ends for longer WB, homemade upper links
- Dravtech Medium shocks internally limited 5mm with soft front springs and medium rear and Trx8351 caps
- Holmes Puller500 13tXX
- Castle Sidewinder Micro 2
- Holmes SHV800 front servo, SHV500V3 rear servo
- Futaba 25mm servohorns
- Sanwa RX482
- 2.2 Crawler Innovations 6 bolt wheels
- 5.4 Proline Superswamper SX with Crawler Innovations soft front and medium rear foams

- AR44 axles with AR60 C hubs and china brass knuckles front
- Stock short side AR60 shaft on one side and cut long AR60 shaft on other side
- Boom Racing Overdrive gearset 27/8t front and underdrive gearset 33/8 rear


Pretty heavy cage

Some dremeling was needed on the skidplate and transmission to fit inside the cage

With heavy wheels and light axle housings, this was the first time on the scales

Some training sessions before comp season (5 months ago now) :ror:

Comp season started with new wheels and foams, much better to drive

Then this started to happen a few times on both front and rear, and I got tired of the weak plastic housing :twisted:

As I enjoyed using AR60 outers and was using really wide 850 hubs to get the width I liked, I thought that XRmod AR44 might the way for me.
So a new revision on drivetrain was needed :ror:
- Beeftubes AR44 wide XRmod Brass housing front
- Beeftubes AR44 wide XRmod Aluminium housing rear
- Axial XR10 universals front and rear
- SSD c hubs and knuckles rear
- Vanquish c hubs front
- Dlux Brass knuckles with outer brass ring front (borrowed from my Pro rig meanwhile)
- Boom Racing servo mount rear (printed front, waiting on new parts)

Used the same Boom Racing OD/UD gears as before.

Time to rebuild!

And a new weigh-in revealed not too shabby weight distribution.

Time for more comps!
I got the XRmod parts on the thursday, 1 day, before I headed to Norway's version of Scale Nationals :twisted:
But got the car ready, and with only driving it 1 min before the comps, I was pretty nervous to see how it would do!

16 rigs in Class 3

And it ended with a 2. place finish! Very pleased with that, considering little time to test and tune before the comp

Results from Skala NM (Scale Nationals) class 3

Then two weeks ago, we did a new local comp where I managed to get 1. place in Class 3
Season ending in that cup is this weekend, so hoping for a new strong finish but competition is tough!

Final round of our cup went down 1 week ago.
It ended with a new 1st place in Class 3 8) pleased with two 1st places in a row!
Sadly I had a bad start in this cup with a 18th place and a DNS, so I only ended up 5th overall.

I have been driving with some 3D printed lower link mounts on the rear axle, and have been afraid of cracking them :shock: So I installed some brass link mounts on the front, and moved the original Axial link mounts to the rear. Along with a brass diff cover on the front axle
