84385 Honda NSX Build

Recommended Posts

Hey Guys.

Thought id so a build thread for this kit. Might take a while, I'm waiting on the paint etc.

It seems to be a special edition and comes with some headlines:

Composite Bathtub Type Frame incorporating Space Frames & FRP Plate

Front Kingpin & Coil Spring

Rear Rigid Type w/CVA Oil Shock

Rear-Wheel Drive Ball Differential

RS540 Sport-Tuned motor

Sponge Tyres

I purchased the kit from RCmart and it arrived surprisingly quickly. I couldnt find it at any of the UK sellers.

The kit arrived as so:

First up was the usual setting up of all the bits on my coffee table.

I really did worry that bits were missing, seems like there is nothing to it! But, its all there :)

It was only at this point that I could see what colours were needed, so some PS2 Red and PS5 Black have been ordered.

I forgot about the Smoke (PS31 I think) so that was ordered yesterday.

Step 1: charge the battery, yes really :)

Step 2: The uprights. Held in place using a grub, this is not something i'm used to as I dont do on road at all, but it was interesting to see a different style. I dont know why im not a fan of on-road but this might tempt me over.

The remainder of Step 2 was to attach the uprights to the front plate which seems to be made of nice FRP.

The coil springs are added on the upper side of the shaft which although tiny, gives some limited spring for the suspension.

Step 3: Basically, this was to simply add the above to the Lower Plate and bumper as per the pic below:

Step 4: Setup the servo. Usual story, power it up and get it centered.

Ive went with the stock Sport Tuned with a cheap hobbyking servo and ESC combo. It does the job fine for the ones that end up being tested a little then put on the shelf.

And of course the usual Tamiya white P Parts for the servo:

That'll do for today :)

I dont know to be honest... doesn't look like a F103 from the pictures I can see unless its a variation of it

Having a dig around it seems to be close to the F102 chassis by the looks of it

It's a group C chassis, the original NSX had a mix of red and black parts.

Step 5: Nice and simple, just a case of adding the tie rods to the servo

Onto Step 6: This was adding the above cheapo servo to the front plate by usual way of the plastic pillars.

The servo was attached to the lower plate which was then screwed to the bathtub. A simple cross member is attached above that to sandwich the servo in place basically. This is black on this kit, not red as per the top left red item on Waterbok's post above

A few pics of the steering/suspension plus one of the underside as per Step 6, just to give you guys an idea:

Step 7: This was the building of the gear casing. Nice and easy, just a 4 sided piece held together by 8 BB5's (12mm)

Step 8: Last of the FRP parts, here we take the T-bar and attach it to the bathtub. We then attach the above gear casing to the FRP T-bar with some spacers. Note that a large black O-ring is used under the T bar to give it some flex.

Onto Step 9: Rear axle construction. The kit seems to be supplied with metal bushes and bearings throughout, no plastic here. I have some spare bearings to replace the bushes but here the kit includes 2 x 1260's.

The process here uses some clinch nuts which I'm not a huge fan of, but they seemed to hold ok. The shaft itself seems strong enough but the metal joints at each end, although metal, seem a bit light.

Last one for tonight, Step 10: The motor! Nice and easy, held in by the usual two screws but through a reasonably thick but stubby motor plate. The wires on the bottom have to be bent up to fit, but no issues here.

Interesting chassis. Is it faithful to the original?

Seems to share quite a bit with the early(ish) F1 cars.

The F40 and a Nissan LeMans thing were same back in the day - is that correct?

These are the C-group models

58088 Mercedes C11 (1990) re 58351

58091 Nissan 300ZX IMSA (1990)

58092 Jaguar XJR-12 (1991) re 58352

58094 Honda NSX (1991) re 84385

58098 Ferrari F40 (1991) re 58356

Nice thread! Group Cs are great the build (and customise) but rather hard to drive...

Parts are shared with the F101 but they have a bit more in common with the F102 (front suspension, gearbox, T-bar).

I'm a big fan of the body shells they made for this chassis.

:)

Edit - funny thing about these cars is that, depending on which hole you use to mount the front suspension on the chassis, you can create three different wheelbases - from 240 to 280mm.

Its been a fun build, didnt expect it, but its been interesting.

One thing that seems to be missing is masking for the shell, appears you need to mask it yourself... i have zero patience, so that will be fun!

Step 11: Spur gear and diff. It uses a ball diff with 6 steel balls. It actually uses 3 1280 plastic bushes here, I thought i had some spare but unfortunately not so I had to just use the plastic. Simple process, the spur/diff goes on the end of the axle. The motor and pinion are then adjusted to fit... its a 14t pinion that comes with the kit as standard.

Onto Step 12 & 13: One single little CVA :)

Not much to see here but I always like building these little shocks... these two steps didnt take long! I added the spacer at this point but once its on the chassis, there is no real need as its compressed.

Step 14: Mounting of the CVA onto the damper assembly frame.

Step 15, 16 & 17: These areas took the shock assembly, added it to the chassis by way of 6 x 18mm's as well as install of the electrics. My on/off switch didnt fit the holes so I settled on one screw but its plenty strong enough. Lots of room in the tub, not short on space at all:

Step 18: Front and rear body mounts added. Also added the antenna pole holder and two little plastic parts that stick out on the side of the chassis. Im no expert, no idea what they are for!
