Hi mate.

yeah been browsing some showrooms and saw the coil over conversion are CRP, didnt really know about the rest. Looks like the car might have been a ex-racer maybe.

is everything CRP or are there some other makes? never seen them front tubes before and duno what the rear driveshafts are about [8)]

[madbad jezza]

i,m pretty sure everything is CRP - although i dont know about the tubing. but yeh, even the rear axles are genuine. i read in one of my magazines that CRP did the rear axle assembly, and although there wasn,t a picture, the ones in your picture fit the description thats in the magazine article. i,m always on the lookout for those kind of parts - especially the coil conversion kit for the dampers. have you taken the dampers apart yet?, because it was possible to buy a better piston kit for those units.

nice find [].

I got a set of CRP coil overs nib & those look a bit different to me as I can't see a lower spring cup, here are my other set

Swing arm mounts don't look like my CRP ones, as mine have no brass bits on them (?) does'nt mean they're not of course.

Also never seen a diff like that before, deffinately not thorp or rc10, I assume screws and plate are on the other side.

Oh yeah and the brass middle gear looks like a top gear on the middle shaft as CRP brass gears were narrower (less friction). You can just make it out in these pics

As I remember CRP rear drive shafts were solid alloy disks with one stainless locator pin, those look very different.

Interesting haul Volky [^]

I think I sent Chris a set of those rear shafts (top left by motor wires) for the community car - drop him a mail see if there was owt on the bag by way of manufacturer

[volksrod68]

cheers Twinset, will do that. Talked to sonic today and he said that they were home-made jobs, but i dont really see the point of going to that much trouble? they are top class pieces and i think all 3 cars i looked at had them on.

Easy one first. The motor is an MG Buggy Special made by MG Model Products. In the early 80s this was the motor to have. Many national meetings were won with one of these, even national championships. The company was run by Mick goddard, who used to build motors for slot racing in the 70s, but as the sport died out he moved up to RC. MG have not been around a while, but they produced race winning motors for years.

The motor states it is a 25 turn stock class motor. When we started racing buggies in the UK we had no rules to begin with so they were generally made up as we went along. Standard class motors were sealed endbell motors, modified class motors were basically the same can but ballraced.

The gears and diff look like they were made by Nodis Racing Developments, a small UK company that reproduced gear sets in brass for the SRBs and Holiday Buggy/Sand Rover. The differential certainly looks like one of theirs. If it is it is actually a gear diff, and all the gears will be machined.

The rear axles are not CRP ones, like Scorchio said they were flat disks with a pin that located between the wheel spokes. They look home made to me, they are easy to make. Take a pair of worn out rear axles and remove the drive hubs from the worn out axle. Get a length of 5mm steel rod, file a flat on one end and cut a thread on the other. Turn the disk to fit on the axle. Slide the disk and the old drive hub on the axle and drill through to bolt the drive hub to the disk. Quite easy and quick to do if you have access to any basic lathe.

Not sure about the rest though.

Joe,

Looks like the coil overs are home made aswell as the axles. Seems our racer was a bit "handy" and was able to build a most of his hop ups whitch would make sense if he was a middle aged man who maybe worked in a workshop for his real job.

Who knows?
