Nice Nissan...I think it's the nicest and most realistic of the Tamiya Gr C bodies.

Hey Marcos, I just so happen to have a Jag as well as a 787B. Both cars are used but not worn out, (decent tires, etc.) however, the 787 body has never been run on the track and is in perfect condition! I'm local in the Seattle area so, LMK.

If someone else doesn't jump on that 787B, I might be interested.

Is it possible to put the Lemans body you can buy at RCMart on the Group C chassis?

I have the Nissan R91CP chassis

Smile TRF101W LM + Nissan R91CP

Hi folks, I give you my last finished project : A Nissan R91CP with a modern F1 chassis.
I usually run 1/10 buggy, but I like scale looking car and it's not easy to find scale buggy (although I prepare a UMP "Unique" Bob Rodine réplica), so I made the project to put a Tamiya group C bodyshell on a modern chassis.

The chassis : a TRF101W (W for wide, 200mm instead of 180mm for the TRF101) it need to be extended of 10mm)
The Bodyshell : Tamiya Nissan R91CP (I try to find a Mazda787B bodyshell - I love it - but I didn't find it and it's wider)

This thread is a compilation from a French forum who help me a lot RCF1.fr


First of all I need a 10mm longer chassis. So I re-made the vanilla chassis blueprint and I add +10mm at the side pontoons.
The TRF101LM's chassis is machined B)




Next I have to do some kit building to take some measures for the designing the parts need for the body.


Build done,(there not a lot of part, it's fast ;-) ) I made some approximate measurements "à la louche" :-p


After that I use paper for a better projection of bodyshell holes


Building of prototype body supports in old PCB (that's FRP)


For the rear it's a mock up drilling throught blueprint, for the front it's made with CNC to verify assembly with the front alloy suspension block.

Dry assembly :-)



Et voilà, everything is OK, I just have machined them in Carbon fiber B)

Some picture of the build :

I cut off external lip of the Pit Shimizu


The cutting part are inside the body, we don't see it after :P


I add to cut the wing support (ref 9005328) it was on the button head screw


Perfect build, even I have to raise the front body post of 6mm. B)


I had to put a lot of rubber band in order to made a good tire gluing


Front tires are a little too wide, but they seem too be OK in term of rigidity


the body is sligthly marked for the Nissan colour schem (thanks Tamiya I use a CD marker to ease the application of tape masking.


Old school paint masking, I made vinylic adhesive band of about 5mm wide in order to do edges. followed by paint adhesive inside.


Paint done, I open the engine air intake, I hope that help to cool down the brushless motor instead of feeding the V8 of the full scale car.


I chamfer the plastic part in order to hide the ugly screw


Toshio SUZUKI ! Doing the driver suit replica is a hard job, thanks to Internet and Youtube I was able to find 1991 coverage


Hair Dryer is a must have for help decals to follow curvature of the helmet


I wet the large decals in glass cleaner in order to put them in right position without bubble


Same is done for the litlle decals to unglue them if we made a mistake, and always hair dryer for soften bent decals


I black painted the headlight on exterior side to have satin finish. I let some protective film in order to put led light


I made the side mirror in lexan with Spazstix chrome, it is much better than the original decals. I use a screw to attach the side mirror instead of body clip that I find a little to big


I reinforce the front body with glass fiber


I use some E6000 or Shoe GOO in order to glue the glass fiber on the body


Toshio SUZUKI is ready to take the 1992's 24 Hours of Daytona


Back to the chassis, I check up the left right balance... great at first glance B)


The secret ? Everything is installed in line, too easy :P


The whole thing weight 1210g ready to run


I setup the ride height to 5.5mm front and rear, hoppfully Tamiya give us 3mm shim fo lowering the front end (design for foam racing out of box I think...)

Final picture of the car, the blue paint is a little too light, we see the white baking :-( In true it's less visible














Between 2 training day I added light (led bucket in 3d printing) a diffuser (also 3d printing) and a central damper instead of the tube damper.


A little review of the damper assembly (ref 54342)
The rod is polished (quality Tamiya )


You can frankly deburring the rod guide


I use lithium grease (it's much better than the associated green slim and it's cheaper)




The oil damper is mounted :



I would like to made a better wing support with Led support and a diffuser... it's solidworks time !


After some time 3D printing... (I order my 3D printed part on Shapeways, it's take some time but its a good quality)


Note I also have Led bucket for front lights B)

Et voilà :cheer:


The true Nissan R91CP who won 24h of Daytona in 1992


Back to the RC, rear pod view with the diffuser


With head lights :




Note the gurney flap on the wing on the last picture for improving downforce.

About the car behaviour, the diffuser add a lot of rear stability but it's still instable at high speed. with the addition of the gurney flap, the car push a lot


I will try to make video when I have some time :-)

This is a work of art. There aren't many hobbyists like you left anymore!

Thanks Howardcano, I have the luck to have Solidworks and access to cnc and the 3d-printing is also a great addition. I know how to use modern making method, but I'm not as good with my hands when I use hand tools
