Looks fabulous!
The trick with soldering is that you need a good iron, with lots of temperature, ideally a variable temp style.
I use an RS Pro solder station with multiple temps settings, it makes it so easy.
And make sure you buy good quality solder too, none of them he cheap Chinese stuff!

Good soldering Nice, hop I can get close to that.

first thing I did was sniff 'em.
Received my organiser today so chucked my tools in. I'm under no illusion that I'll need say a body reamer or scissors when I'm racing but it's more to just have everything in one place for now, it'll find it's own level as we go

For neat soldering, make sure you buy solder with decent lead content, ideally 60% tin / 40% lead. Most solder available to hobbyists has almost no lead, consequently it has a very high melting point and it's almost impossible to get large motor, ESC and battery connectors hot enough before the heat conducts elsewhere and causes a nasty mess.
RS Components won't sell lead solder to the public, but CPC Farnell will; this is what I use to great success on my RCs, along with a cheap Chinese soldering station:

Cheers for the info Pete. My next door neighbour who's an electrical engineer type is bringing all of his works grade goodies over later to get it all done. It's something id like to do myself but then id have to buy say another £40-50 worth of stuff for one job.
This way I'll get it done for a couple of beers

Well, the update you've all been waiting for!
New wheels / tyres on the WLTOYS
But no, It's been a tough week with the 3.1 tbh, for one reason or another the soldering did not get done by me, my sisters boyfriend or my neighbour. We tried we failed. I ended up taking the Yoko down to Western Valley Models in Risca for Heldey to rescue / tidy up and he did a cracking job. Unfortunately the PS paint I wanted wasn't in stock so that's been ordered for the middle of next week.
BUT, with the soldering done she's moving! I've set my EPA and had a little play around with the ESC settings but pootling around the living room it looks bloody awesome
I asked WVM to add some bullet caps onto the battery terminals so some CORE RC caps now adorn the vehicle. I also picked up a CORE RC setup board because ....
well, RC stuff inni..
I don't actually have any setup equipment yet but SKYRC do make a lovely anodised ali camber, caster, toe, kit
So the car is now looking like 'dis
Paint next week, will order a chassis protector from SEMCS and then well, racing next

Just stumbled upon this thread after a quick google search.
It’s as if you’re a month or two ahead of me. I’ve been looking at the Yokomo YZ2 Cal3.1 for my 1st dip into the world of 1/10th buggies in about 20 years and guess my local club……. COBRA.
I’m planning to head down Sunday for a little watch. I’ll keep an eye out for some blue smoked windows 😂.
Keep going with the thread. Great read!

That’s great bud! At this rate you’ll have built your car and be racing before me I will of course whole heartedly recommend the Yokomo (based purely on bias and a complete lack of experience of course) It would be interesting to see your journey on here 
I’m thinking of popping down Sunday too, i haven’t got paint as there still seems to be a shortage but might wander down anyway. My leg is out of the cast now so I don’t stick out quite as much and can move around a bit better. Hopefully bump into you, i’ll be the guy limping and looking a little out of my depth!
A few more things arrived in the absence of actually using the car
Handy to have another lipo bag as i’ve got 4 in total now and of course I needed a fancy zip up bag for the set up board I don’t need
it’s just an obsession with having stuff always arriving in the post I think..
I release too i’ve made a monumental school boy error with my wiring. I was gutted that whichever way my battery was placed the positive and negative wires crossed. Well it dawned on my a few days ago that all I have to do was turn the battery over
That would have reversed the terminal orientation and allowed the cables to the routed beautifully, dammit. I’ll be going back to get the wires re-soldered as that will bug me forever if left as they are.
Realistically be another 2 weeks before the tyres will touch the carpet of a race circuit but not too far away now.

Well I popped down to COBRA today. Was a great turnout as it was a comp day.
Had a good chat with Lee from L&L models. Discussed a few bits so no doubt I’ll be parting with some cash soon enough.
Watched a few Yokomo’s go around and all seemed to go well. Hopefully catch you down there soon enough.

Thats good bud glad you got down. I wasn’t able to make it unfortunately but should be there next time. I was at a comp day there not long ago and most of the guys there didn’t seem short on pace.
That’s basically what I did, to be fair Lee gave me about half an hour of his time in which he answered all of my queries and gave me a load more of helpful advice. We may end up with similar electronics in our buggys
See you down there next time bud!
i’m planning on going up to Midlands Raceway next Saturday potentially with one of the boys from Cardiff for a test afternoon which i’m looking forward to, blinking thing might actually be painted by then

As I really like my lovely bronze chassis I thought I'd protect it with a .. protector. Most were either generic that had to be cut to fit or designs covered in flames. I'm not a flames kind of guy so kept looking and found this one from SEMCS. I really dig the design and on the website I saw they could be made to order in lots of colours, amazing! Having contacted Sam there I enquired about a pink / yellow combo (to go with my non-existent, never to arrive Tamiya paint scheme) it turns out the manufacturer of the chassis protectors is no longer trading (arse) and he had only the grey / blue or all blue designs left. OK I thought no worries and got one ordered. Fitting was super simple and rather than using soap and water I decided to line it up and slide it on dry using the backing film to guide the sticker rather than removing it and instantly having it stick to itself requiring it to be promptly put in the bin
Super happy with the quality and fit of this, having the hardware holes pre cut is a huge plus too.
Also from SEMCS I got hold a THR (Tudor-Hart Racing) shock tower protector. Saves the carpet from damage in the event of a roll over (although this design allows the nyloc nuts to dig in still) and more importantly saves my shock tower from damage. Looks cool imo too
I may have something else arriving tomorrow, from Czechia!

Well the penultimate evening before the big Sat test up and Midlands Raceway and I'm still painting the blinking shell. I wasn't happy with the slipper cut out as it was a bit ragged and too small so opened it up and tidied it with the air die grinder
Success. Id earlier in the day gone to get some paint, I really wanted a predominantly white shell as I think I mentioned but basically the hobby shop only had these colours which I could see working, so the body is going to be shades of pink
So I started laying down the ps-29; 4 coats in total with 20 mins in the warm / dry in between. Probably used about half a can.
Having let those layers dry I looked at putting an edge to the windows, quite fiddly with the craft knife and I've never done it before but overall really pleased with how the surround turned out. I wanted quite a wide border to somewhat break up the pink and thought silver would suit a little better than ps-5. I didn't realise the ps-48 was fancy / expensive (£11.99!) until after I bought it! 3 coats of the silver and it started looking ok imo
This is where I am now with it. The translucent pink will be the last colour to go on to tint the windows and I want to back the whole shell with white first to male the pink 'pop' but that's not arriving until tomorrow. the colour here isn't the actual colour that the shell will be as jconcepts for some reason colour their protective film green, will only see how it really looks tomorrow when I've peeled it off.
That package from the Czech Republic turned up today, merch!
A Yokomo wind breaker jacket and polo top. Quite expensive in the UK but was browsing MIBOSports website and saw them for about £15 each, had to do it for that price! So now I'm a full kit Yokomo w
ker
I hope to finish the body tomorrow and get some stickers on it.

Looks fast already very nice !. Midlands will be great for practice. Jump at the back is maybe a bit much for a beginner but you can roll over it nicely. Take it steady on the track it is tight and twisty but will be really good for getting your eye in. Try and arrive fully charged so you can really pound the laps in. I generally run old tyres especially if just practice up there as track is really grippy. Have fun
Cheers roll, it might have to stay looking fast rather than being fast!
I get the feeling I'm going to be low on patience a little tomorrow. In no way abusing the buggy or wishing to crash but I can see me wanting to push quite early on, we'll see how that goes. All batteries charged up and ready to go!
Test fit earlier, seems to fit ok for something not purpose made for the job
Well the buggy bus finished. Applied the last few coats of paint this afternoon and she's done
The window tint came out of the can like a shotgun, hard to get fine control with the Tamiya spray cans (at least for me!)
As always the hue isn't captured perfectly as on my monitor the pink looks slightly different to the shell in real life. You can see the cabin area of the shell is a good few shades darker than the sides, I'm guessing that's the silver backing of the window surrounds bringing the pink down quite a bit, the white on the flanks may be lifting a little? therefore exaggerating the difference. I don't care but it's an interesting observation.
Quite happy with how the tinting came out. Overall quite enjoyable but wow it's tie consuming. The wait between coats really adds up and seems to make the job last forever; especially when the light is lost quite quickly now.
So there we go. Midlands tomorrow, I'll try to capture some of it at least and give a report when I get back

Was a great day!
Thankfully that happened about 20 minutes before we were due to leave anyway so no dramas. I said it didn't I, "I'll just have one last run.."
Left my place about 9:45am and got up there for 11.50am, good drive and and the weather was sunny which was nice. parked up got our first look of the place (one of the boys from COBRA came up with me)
One thing I wasn't expecting was just how cold the place was! ooff it was baltic in there, thankfully I took a coat. We paid our £10 and chose a bench next to the circuit behind the rostrum and got set up. It was surprisingly quiet for a good 45 mins and then people starting rolling in but it never felt crowded, a good number of people to keep things interesting I'd say.
Chucked a battery in and it was time first it's first lap
Initial impressions. The car was instantly familiar and drove over all quite 'neutrally' i.e. it didn't do anything I wasn't expecting it to or handle in a manner I couldn't control easily. The steering however was quite numb and slow to respond. I initially turned the expo on the steering up by 50% to try and improve matters which seemed to help a little. I also set the bec voltage from 6.0v to 7.4v. That also helped but the car still lacked front end bite, not massively but this is something I'll need to work on. I think in a way that helped me as it wasn't too difficult to control in the turns and refused to traction roll, I'd prefer it too numb at this stage than too 'darty'. Within a few laps I was getting comfortable with pushing on a little and started to really enjoy the laps as the car warmed up and I started learning the lines and braking points etc. The circuit is great, quite tight and technical but good fun too.
roly you said
Within tolerance I think. Maybe a fan will be needed next summer but in this cold weather that's acceptable.
Out again and ripping round, me passing some people, more people passing me. I was glad that the car was stable in the air, seeing it jump and land was strangely satisfying and quite mesmerising. After trying to clear that aforementioned double the car came to a stop and wasn't responding, got it back to the pits..
..and turns out the esc had pulled off it base and yoinked the bullet connector out of the + wire. No dramas, had some spare 3m double sided tape and re-seated it and off we go again. Had lunch delivered
and went back out. I got speaking to one chap and when I stated it felt numb on the front end had a quick look over the car and made some recommendations, one of which was moving the rear shock top mounts from all the way 'in' to further in the middle setting. I repositioned them and it felt like it made a good difference on braking and initial turn in as the more upright shock loads the front end more under braking.
on my last run of the day I got a little loose and caught the ply-board wall of the double jump and KABLAMO!
OSF tie rod snapped. That was at about 3:30 so we were more or less ready to pack up anyway.
So overall a really really enjoyable day. It's such a shame that there isn't a permanent venue locally that we can go to as I'd happily do that much more often than I'll currently be able to. Is what is.
On the tie rod front they seem to be out of stock everywhere. So not sure how or when I'm going to get hold of a replacement! Easier to get parts for the WLTOYS
Sorry there's not more action pictures or videos but that's how the day went, I was too busy having fun! Can't wait to do it again..

and you weren't wrong! I hit it and cleared it plenty of times, it just wasn't always in the right place when the buggy touched down again! I found it really hard to judge the car being straight as the jump is directly adjacent to the rostrum and depth perception was difficult. I elected to roll it for most of the time as it was just a case of saving the car from multiple barrel rolls which would eventually break something. I came off after the first pack ran down and tempted the motor Within tolerance I think. Maybe a fan will be needed next summer but in this cold weather that's acceptable.

Nice ! Great write up and good to see you had an enjoyable day. Midlands is same layout as we raced last week which we all enjoyed very satisfying when get the jumps right. Now you have the basics cracked you should be ready for your first race event. I'm sure somebody at Cobra will have a tie rod you can borrow if struggling to get one.
Time to upgrade! https://www.tonisport.de/en/spare-parts/yokomo/yz-...
Great to see the cars finally painted and on track. Loving the colour scheme btw. Was thinking of incorporating some pink into mine. Will have to have a re-think now 😂.
Midlands looks like a great set up. Maybe asking if you fancy another trip when I’m all built and ready to go.
Like the others have said, ready for your 1st race met now. Keep the updates coming.
