Axeboy 297 Posted August 5, 2014 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: 1 Share this post Link to post Share on other sites

Axeboy 297 Posted August 5, 2014 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. Share this post Link to post Share on other sites
Axeboy 297 Posted August 5, 2014 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. Share this post Link to post Share on other sites
Axeboy 297 Posted August 5, 2014 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: Share this post Link to post Share on other sites
Axeboy 297 Posted August 5, 2014 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 Share this post Link to post Share on other sites
neverfollow 599 Posted August 5, 2014 Looks great so far. Is this an F103 chassis? Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 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 Share this post Link to post Share on other sites
waterbok 1282 Posted August 6, 2014 It's a group C chassis, the original NSX had a mix of red and black parts. 1 Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 Step 5: Nice and simple, just a case of adding the tie rods to the servo Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 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 Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 A few pics of the steering/suspension plus one of the underside as per Step 6, just to give you guys an idea: Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 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) Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 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. Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 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. Share this post Link to post Share on other sites
Axeboy 297 Posted August 6, 2014 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. Share this post Link to post Share on other sites
Cplus 94 Posted August 6, 2014 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? Share this post Link to post Share on other sites
waterbok 1282 Posted August 6, 2014 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 58102 Mazda 787B (1992) 58109 Nissan R91 CP (1992) re 84264 58153 Daytona Thunder (1995) 58174 Street Devil (1996) (Parma body) Main difference the rere have a black A-tree sprue and the crossmember over the servo has body post attachments. If T will rere this too? Share this post Link to post Share on other sites
dutch_rc 71 Posted August 7, 2014 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.

Axeboy 297 Posted August 7, 2014 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! Share this post Link to post Share on other sites
Axeboy 297 Posted August 7, 2014 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. Share this post Link to post Share on other sites
Axeboy 297 Posted August 7, 2014 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. Share this post Link to post Share on other sites
Axeboy 297 Posted August 7, 2014 Step 14: Mounting of the CVA onto the damper assembly frame. Share this post Link to post Share on other sites
Axeboy 297 Posted August 7, 2014 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: Share this post Link to post Share on other sites
Axeboy 297 Posted August 7, 2014 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! Share this post Link to post Share on other sites
