First, a situation-report:
I allready had a RB5, originally from nathan Ralls. That car had allready some modifications done compared to the original RB5, but is not 100% the same as the latest edition.
The RB5 CMS can be build, starting from every RB5-car, AFAIK (... but I'm not certain if the latest RB5-edition uses the same spur-shaft?)
Fabs designed this kit, wanting to make a mid-motor-version of the RB5.
The RB5 is a very good 2WD electro 1/10-buggy.
He build himself a prototype,
tested it (with the help of some good friends)
it turned out to have more steering then the Losi XX-CR2, but being more forgiving then the Asso B4 and GREAT to drive...
and he made a batch of 30 kits.
All chassis are numbered and it is intended to be a limited kit!
Unfortunately, Fabs had to discover that some of the parts were not made as he ordered them. As an example: some of the screw-holes were designed to be 3.2 mm diameter ... but we discovered they had to be drilled out as a 3MM-screw would not go through.
Some holes were intended to be counter-sunk, but weren't, ...
So this explains why, when building this kit, some of the parts did not fit 100%, but this was always resolved with a little bit of filing or re-drilling.
This also explaines why Fabs was not able to ship all kits immediatly. He will be (or has allready) re-finishing all the parts that need to, to be certain that they actually fit 100%.
aaannd, I personally think that it is better to have some parts that are a bit hard to assemble at first then parts that are to loose.
I met Fabs online first, IRL at the 2010 EIR-race in Charleroi, and we kept in contact over the internet.
As far as the kit concernes: Fabs told me about a race on a local (Paris) track and I decided to just drive all the way over to his place, meeting him at the track of Maison-Alfort on saturday, pick up the kit, build the kit on site, and race it on sunday.
This all happened as planned, except for the raining and the fact we did not have some cover and were intereupted twice, having to quickly pack everything and hide under a tree, and to re-start the build.
I tried to take some pics, and did so, but I'm not a very good photographer, so the pics are not the usual oOple-quality (sorry) (but hey, better then nothing, nah

)
The track @ Maison Alfort, France:
Fabs gave me a cardboard-box, containing all the parts.
I started with dis-assembling my RB5 and did build the kit with Fabs directions. I'll try to copy them over here.
! You don't need anything else then:
* your RB5-car
* Fabs CMS-kit
* two extra bearings
* 4 extra button-head 3X12 screws (for the rear shock tower)
* the usual tools, greases, ...
* ... and maybe a fresh Duvel, ... but that's optional I guess
