3mm Rear Arm Mod
 

This is not something that is required, however, with the high grip tracks in the UK, this may be something you might find useful if running on carpet or astro.

I have removed 3mm from the rear side of the rear arms. It increases the available wheelbase from 275-278 up to 275-281. As a point of reference, the Xray XB4 is 279-281, so you can see how much adjustability this gives you for different surfaces.

Pictures below, any questions just ask :thumbsup:

Wot wing is that your running. ..Steve

A Yokomo one. It came with the YZ2. I would normally go for one of the LMR wings, but due to the low wing mount, this seems to be a good fit with the raised section over the wheels.

evo vs b-max4
 

hi,
can this one be competitive with b-max4 on small-tight high grip carpet track?

have been decided to go with b-max, but this thing realy looks good...

what option parts is necessary for this kit to be good on carpet?
I heard that kit springs are to soft...is it any other mods necessary?

thanks
 

Cheers for the pics Steve, ive been chatting to pete about one.

are you at bury tomorrow,would be nice to get a close up of one. Hoping chris Elsworthy has his running

as one of the guys before said, be good to see them up against the bmax

Not racing tomorrow mate as I'm at a wedding darn sarff. Will get it built this week then begin testing. Anybody running the new 104 evo who needs advice let me know as I would be happy to share/discuss.

Team SWorkz UK/Answer RC

Yes!

By the new design features the car should be better than the previous version on high grip. And even more so if you increase the wheelbase like i have.

On low grip you have i think the shortest wheelbase available on the 10th racing market, so nothing is going to come close on a really tight twisty track.

Some guys in Aus have already done a comparison between the S104 Evo and the BMAX 4 iii.

Er nope im down South mate :p

As Chris said though, just ask if any questions about the car etc.

Off to Herts now to pit for the Sworkz nitro boys

Steve,

Interesting mod, would that be worth doing on my current runner? Also interested to know if the motor mount would fit my currebt runner.

How easy is it to whip out the diffs?

Hi James

Probably not a bad idea to try. you need to think about lining the shocks up though. The new car angles the shocks forward, so moving the bottom arms backwards actually brings them in line with the standoffs. I cant remember what the old car is like.

The motor mount may fit, you can run a slipper with it, so the spacing should be the same. You would need the other centre bulkhead peice though as the diff sits about 7mm lower on the new car.

4 screws pretty much. The front of the gearbox case just comes away.

thanks
 

have you had chance to run it yet? think im getting my lad one this week off Pete

i gave it a run in the astro yesterday at Herts.

Seems very good. Puts power down really well, very stable and loads of steering.

thanks
 

My lad loves lots of steering so will be happy with that

How are the arms on it? any breakages?

Began my build last night and must say the quality of the plastics and machining are as good as I have come accross.

Experienced a little bind in the drivetrain once the diffs were installed which I found to be caused by the screws on the gear diffs not being wound down super tight. In the past with other cars I have only had the 4 screws in the diff snug to avoid cross threading the plastics on the other diff half so tried that approach on the Evo to begin with. This caused my bind as the diffs are a very precise fit in the gearboxes so make sure the screws are done down tight when building.. The plastics on this car I'm sure will take the extra pressure.

Other than that the car has built superb so far.


Chris

You will be going some to break the plastics

nice
 

put some pics up when your done chris :)

what configuration have you built it in ?

What electrics are you going to be running

Ok, wishbone mods pretty simple as the shock mount can be modified. Motor mount will hold off on until I can see it, as there is always a way of making it work.

I've only got as far as building the front and rear end so far so still have a little way to go yet. As Steve says you will have to hit things pretty hard to break the wishbone on this car, there is plenty of beef around the inner hingepin. To be honest since I returned to racing 3 years ago I haven't broken a wishbone on any car, front bulkheads seem to be the weak spot of most modern car's but time will tell with the Evo.

I will be running Absima electronics as Answer do not offer any 10th options at the moment and will be running exclusively in shorty config as it gives the best overall weight distribution.

I have plans fairly soon to get an aluminium chassis made with 25degrees of kick up built in to create a proper forward motor 2wd car for high grip. To me it seems like it will be a fairly simple task to achieve by removing the forward drive shaft, the front drive shaft then remove the front diff and add weight into the front gearbox to keep some forward weight bias.

In shorty configuration the Evo mirrors the electronics layout of the Team C TM2v2 which is the best 2wd I've driven.

Time will tell,


Chris

thanks
 

Cheers Chris,

We've about 6 pairs of saddles that we use in the B5m, so was thinking of building in that config... be nice to have 1 one way and 1 the other to test against each other :)

I have an absima cts10, thinking of getting another to put in the 4wd - just unsure what motor to use

The Absima Speedo's are great.. I actually have one for sale at the minute that has only been run for one meeting. If all you have is saddles simply run saddles. One of the main issues for me of the saddle config is the lack of space for mounting your electronics. I use Absima motors also as they have been faultless but these days most motors are good enough. The HPI range are very good for the money.


Chris

update
 

Hi chris have you finished the build yet?

not sure I anyone else knows but i received a suprise email off a local fast driver saying he's getting an evo shortly and offered help with setup, that 4 locals that I know of that will have an evo come October

I would imagine a fair chunk of Answer RC drivers will be getting them.

Mine had its first proper run on Tuesday night at maritime racing. Was off the pace but got quicker every run. Finished 4th in the A which I'm pretty happy with given the level of competition at maritime.

The car is super strong and very responsive.

.
 

How come it was off the pace? its carpet at maritime isn't it?

No new car is gonna be on pace with national F2 drivers on its first run lol. Yes carpet

Finally finished the build of mine today and intend giving it it's first run next Sunday at Bury.

I'm not totally happy with my shocks at the minute they feel as if they have a bit too much pressure when built so feel a bit springy on the bench. I've built them standard with 500/350 oils and fitted AE springs as I like they way they perform.
What oils have you built with Steve? My front end feels very soft and the car bottoms out quite easily when dropped.



Chris

Just putting the final touches to the build and will be running it at TORCH tomorrow for it's first outing :thumbsup:

So far very impressed with build quality, tolerances extremely good and no major issues putting this together.

Chris...... I know what you mean about the shocks. I felt the same when initially building them. I've upped the wt front/rear to 600/400. I'm also running AE springs but wasn't happy with the fitment around the kit shock collars. I can confirm AE collars fit perfectly :thumbsup:

Following tomorrow's first shakedown, I'll share our findings. Very impressed so far :D

Cheers,
Jason

thanks for the updates guys.

be nice to see them with the bodyshells on,

looks like everyone has gone shorty setup.

been looking and theres also a thread on rctech for the evo

Hey Chris

I found that the kit shafts had far too much bite on the orings. I'll send you a pm.

How d

Anybody run their car's this weekend? How did you find them?




Chris

+1 ... also waiting for some feedback how this thing performs on high grip tracks

Awesome
 

First Impressions.............. Awesome! :woot:

We ran two Evo's for the first time at TORCH Sunday and for both of us, very happy with the day and the car has huge potential :thumbsup:

The track layout was changed to a more technical layout than usual for TORCH and the morning was met with a wet track due to the morning dew. Both cars in practice had loads of front end grip on the wet track. You'll never struggle with lack of front end on this car, it's got loads of front end grip to spare!

Track dried quickly for Q1 and now was the time to find out how the Evo handled high grip. Both cars had similar geometry setups, the major difference was shock oils and springs and diff oils.

Both cars still felt super soft on the shocks but put in on the track and it just handled everything you through at it. I did get grip roll when really pushing, but going up one rate on the springs solved that problem without needing to change anything else. With the small changes we both were making, the cars reacted to change very well and we understand each change after running.

We TQ'd and fastest lap with one of the cars and mine P4. Unfortunately I had to leave before the finals and couldn't contend the final but we had a P2 in the final. :thumbsup:

The Evo is built to last, we had nothing break, nothing rattled itself loose and no faults or failures.

For a new car, first outing with no previous setup's to guide us, we expected a few teething issues to overcome but honestly, both cars ran brilliantly and we are both very impressed :thumbsup:

We've still got plenty to work on, for me it'll be the shocks. They are very good quality but as part of building them, I drilled out the pistons to large holes and that is a mistake I wouldn't recommend trying to copy other popular shock setups from other manufactures, you will find it feeling too soft. Keep with the 1.5mm pistons :) and work around these. Only other item we'll check is the centre diff. One of the cars leaked oil, but the other car was much better so we'll check if it was a build issue. The diffs use a single o-ring for the outdrives, so maybe this had an issue on one of the diffs. Something simple to rectify.

For both of us, we've never ran the older car, so first time running SWORKz and the Evo. We learnt a lot, both build and racing. We'll apply a few more ideas for this weekend's Summer Series round at TORCH and hopefully make further improvements as we learn the car.

Thanks Moggers for the detailed report.

An issue I have heard about with this car is too much rear weight transfer causing the car to squat heavily on power then transfer forward aggressively off power, you don't mention anything of the sort so it could simply be an oil/spring issue I'm hoping. I'm going to be running my car for the first time next weekend so will share my findings as and when.

Could you share what springs and oils you found worked for you? From what I'm reading I'm thinking people will need a slightly heavier oil setup on this car especially in the rear. Those look like AE springs also if I'm not mistaken?

Many people are finding that their shocks suffer from a lot of stiction when built out of the box, did you find this also? I believe this is being fed back to Sworkz so hopefully future kits will be improved. The stiction has been put down to the Orings and shock shafts causing a little bind but could be isolated cases in some kits not all. A tip by Steve on here is to run Kyosho Orings and shock shafts from the RB6 and this eliminates the issue resulting in a more consistent shock package... I shall be trying this mod myself.
Another thing that concerns me but not all I may add is the amount of play where the top of the shocks mount to the shock mounts. There is a fair bit of slop before the suspension stroke kicks in which I'm not totally happy with. It appears as though three should be a small sleeve over the shock mount for the shock to pivot on similar to other brands such as Schumacher but there isn't. It's not the most elegant solution but I've wrapped a piece of duck tape (an exact width of tape) around each mount and it's removed the slop, cushioned the shock and still allows the shock to pivot on the mount properly. Just a small tip if it concerns anybody.

If you could share your diff setup also that would be greatly received by all also I'm sure.


Chris

the car does transfer weight F-R and R-F quite freely, as did the previous car.

biggest thing you can probably do is change the centre diff oil. I am running 500k, and will be trying 1mil. It definately does not squat as much on power with the thicker oil.

Beyond that, ad some anti squat at the rear, and anti dive at the front.

currenly running 10k in front diff and 8k in rear, but they feel very free still..i have some other things to work on Tomorrow, but after that i might try 20 and 15

I'll try and post up a setup later, but a couple of things I ran Sunday;

Shocked built with kit shock shafts, but I did replace with O-Rings with AE X-Rings. No issues experienced and no leaks at all. Pistons drilled 1.6F and 1.7R but makes it way too soft. I'd keep with kit pistons (1.5x2) which I'll put back in for this weekend.
Springs are AE. Red fronts and started with Black rear's but changed to Green on rear once grip came up.

Ran 20k front diff oil and 10k rear. Centre was 500k. We'll be testing 1mill this week.
I ran small amount of anti-squat on the rear with high roll centres F&R. Didn't find major issues with it squatting that much, but will continue to try other settings.

Honestly, didn't find any issues with building the shocks, so maybe the AE O-Rings helped straight off. My mistake drilling the pistons out, which I'll rectify this week.

This week I may try slightly lighter diff oils, especially in the front, all depends on weather conditions next week.

Happy to help and share where I can,

Cheers,
Jason

Sorry Chris, you mention an issue with mounting the shocks. The kit comes with a plastic collar that sits inside the shock cap and eliminates any slop. It's a plastic part on the SW-2501807 parts set. From what you've explained, sounds like you've missed this? We've had no issues mounting the shocks on the shock mounts.

Cheers,
Jason

I've obviously missed the collars in the manual, I took another look but couldn't see so thanks for clearing that up, I did think it seemed odd tbh.

Thanks for the setup advice. I've only got the 100,000 kit diff oil for the centre at the minute so it appears I should pick some thicker ones up as it's on the thin side.


Chris
