I'd be interested to see how to cope when you get them out properly. I'm not a fan of the small diameter the Swamper copies.

Well we had a go at ramps etc in garden today and my tyres as well as originals on lads car managed to cope ok was pleasantly surprised at what they got up or over today :cheers:

So now that I have to wait a few weeks for the driveshaft and light kit, I odered the 4 link kit with the servo on axle mount and an alloy servo horn, did not like the the servo up in the chassis with the push rod on a steep angle.

Progress report......

I'm about 90% done. Just got the receiver and ESC to fit and plug everything in, and then paint and fit the body mouldings.

 

(I know you've all seen them naked before..........)

Did some in place upgrades as I went along..... 2 stage spring kit

4 link conversion with on axle servo mount

and some bling wheels, with tyres from Ebay as linked by @Stormbringer

20210311_212156.thumb.jpg.ea8cd4e8d009f0a01c8c3e9b16260d4f.jpg

 

Still got lights and an aluminium servo horn to come yet.

 

The build was generally very good, nice quality feel to the plastic and it went together with only a couple of issues.

 

The first was when building the axle assembly, one of the 'cross' pieces was a fraction oversized so the bearing wouldn't fit properly. I had to bodge something together so I could spin it in a drill and carefully turn it down. 

On the same assembly once I fitted the covers, both diffs were quite notchy, so I pulled them apart and flipped the bearing carriers 180 degrees, which improved things, but not enough.

I ended up cutting some slivers of paper! (12mm x 4mm) to put in before the bearing carriers to shim them up. This worked and they are smooth now.

 

Biggest headache were the shocks. I noted that you guys had problems with them binding so was prepared for that. I gently sanded the pistons down and tried each before finally assembling.

Don't know about you guys, but I though the stock setup (with stock or 2 stage springs) was over damped and the rebound was too slow. Doing a bounce test on the front and the suspension hardly moved.

 

So... I decided to tweak things. after pulling apart, the 2 under piston spacers in each shock was turned down a bit to reduce the diameter with the idea that the oil can flow past easier, similarly the flat spots on each piston was sanded back a tiny bit to increase the oil flow around them.

 

Rebuilt everything and now I'm happy.

 

Should be doing the ESC/receiver tomorrow, and hopefully paint at the weekend

Looking good 🙂

 

The shocks are the only real weak spot to me. I removed more and more material from that plastic spacer with only minimal performance gains, before I got fed up and removed large chunk from the flat spot on each shock. With 20wt oil it now finally rebounds properly. If anything it's a little too fast, I'll experiment with different weight oils but tbh even as it sits it's waaaay better than stock.

I like the look of these as a possible future upgrade but not sure if they'd fit

I like the look of them 👍 Apparently the TRX4 shocks are a good option.

I've had a closer look.

They don't look like they'll work on the DC-1.  the piggy back would be facing out, not against the chassis, so I think when the wheel starts to articulate into the wheel arch it'll actually hit the piggy back.

 

Ah well, they sure look pretty.

I can't find them in stock in the UK (same for most things are the moment!) but these are the ones I've seen used

Good job the car is looks nice and I like the 2 colors,  the only thing you have to do is make it dirty😜.

 

I hope I can finish mine in the end of next week, still waiting for parts to arrive.

Bumblebee haha🤣 like it.

 

I'll run the stock shocks for now, might have a go at some 3d printed pistons at some point. never seen pistons with just a couple of flat spots before, only ever multiple holes in different diameters.

 

The GMade shocks caught my eye a while ago before I got the DC-1 as they do look amazing and they're proper piggy backs too

 

With a bit of luck I'll be able to get out and drive it today or tomorrow, and see if I can get some video

Apart from a lighting kit and a aluminium servo horn yet to arrive, I'm finished

 

Electrics went in on Friday and I had to take it into the garden for a little test run. I was surprised at just how quick it was in high gear on 2S. Not lightning fast, but faster than I'd expected and plenty quick enough for the top end.

Slow speed in low gear was really nice, creeps along slowly but very smoothly.

Last thing Friday I masked the bodyshell off.  Considering its a simple 2 colour paint job the masking took ages. First time using Tamiya masking tape (10mm) and I was please how nice it is to use.

 

Painted the  bodyshell today and after waiting for the paint to cure for a couple of hours, I set to putting on the body mouldings wheel arch liners etc

 

So now its time for pictures........

 

Seat and centre console parts

I painted the grille, and once dry gently flatted the raised surfaces back to black

20210314_000332.thumb.jpg.1a2f7091e4e8636f6c0384be234518eb.jpg

 

 

The paint colours used are all Core RC and they are:-

Metallic Graphite (CR620) roof and bonnet

Yellow Taxi (CR601) main body and seat centres

Metallic Silver (CR621) main body backing and centre console and grille detail

 

Originally the black parts were going to be done in a carbon effect, but I wasn't happy with my test pieces so decided not to risk ruining the shell.

I think it turned out pretty good.

 

looks pretty sweet m8 🙂
