Nick, will post pics up a little later, when I got the RB5, sorry, I mean, Pro-X front end together!!

Dave.... definately no Griffin, I don't think there will be any need for Alloy bits... just to replace wobbly stock parts, lol!!

Jamie, yeah, I got it, bit to steep for me at the moment, unless you want to 'donate' one out of samples, lol

OK, the box arrived, most eagerly awaited, excited for a new 2WD, nervous that it could be a massive hit (good materials) or a flop (floppy plastics). They do say, first impressions count, so on opening up the container, a rather nice kit box is in there, more so, the artwork is a sleeve, the box will make a very good storage box too!

After checking out the parts, a few things are evident, this isn't a cheap kit, to throw away. It comes full ballraced (all except the ackerman plate), the screws are steel, and of the 2mm Hex variety, and, surprisingly, the ballstuds have a hex driver fitting too.

All the mouldings are really well finished, very little flashing on the parts, wishbones, towers, chassis, so far, are made out of a very stiff composit, somewhere between the B4Team and B4FT Graphite. The other mouldings aren't to shabby either, made of good, solid plastic. You may want to grease the screws going into the harder stuff though.

Assembly is easy, elthough the instructions could be made a little clearer at some points (steering assembly), and there is no spacer between the front bearings, not to sure if this will cause an issue on wheel fitment though, wait and see, but apart from that, the parts have slotted together really well, like you would expect, in a pro level kit.

Right, theis is a standard, 3 gear, ball diff, dual pad slipper unit, gearbox. The box is made out of the same material as the chassis, and the fit is very tight, so should stop dirt ingress. Diff is a 12 ball diff, ballraced too, with a caged thrust race (diff lube included, but no thrust grease...). The diff assembles nice and easily, no surprises there, and is silky smooth, the only concern, the instructions lack any info on how to set the diff, and it isn't a 'rully tighten, then back of 1/8th of a turn'.

Once assumbled, it turns nicely, no high spots, and will free up more with use too.

Slipper is easy to assemble, and uses a wheel nut for adjustment.

DCM

it has threaded shocks (build them tomorrow now) and they are either stainless steel or titanium turnbuckles.

DCM
08-06-2009, 10:32 PM
Right, not much to say about the rear, to be honest. It has suspension blocks, to mount the front and rear of the rear wishbones. Hubs have 4 positions for the outer link, it also has a spacer, so the rear hub can be moved forward and backward, about an 1/8th". Inner camber link has 4 mounting holes too, all the suspension mounts off a rear chassis plate.

Am enjoying watching this build, good work DCM :thumbsup:

Theres no doubt its a near on carbon copy of an RB5, is that legal? :lol: Using the origional style rear end rather than the new SP, not a bad thing though, i've never been convinced by the worlds rear end on the RB5.

The only down side to the origional RB5 rear end was that it was far to narrow in the box so it will interesting to see how the Pro-X measures up?

Looking good though, an RB5 with green bits rather than blue and £100 cheaper :thumbsup:

glad your enjoying it, I still haven't found where they have saved so much money though.... Only thing that is more bling than pro, are the shocks, with no teflon coating.The RB5 used to retail at £160 it's only due to the exchange rate that as sent it to £240+. But you would expect Ansmann to have simlar issues in todays climate? Where are they based?

They have done well to price it at £139, on the face of it the quality looks good. So does the design with it being so close to an RB5 its fair to say it will perform well.

No doubt about it a lot will ride on the shocks as to wheather the Pro-X cuts the mustard.

:confused::confused:

G

it is all metric, G, most of the bearings are 10x5, diff output is 15x10, hinge pins are 3mm diameter, same for the shock shafts.

Only let down, that I can see, is wheel fitment, I would of liked to see the adoption of at least the ubiquitous B4/Losi fitment (no, they don't kit, checked already), but, being Ansmann, chances are, the wheels will be cheap!!

Whats the diameter of a Team Associated piston, in metric please?

DCM
09-06-2009, 10:55 AM
Right, shocks, they are actually quite good. Casings are an alloy, anodized in a rather nice green colour, two piece shock tops, with a diaphragm, the lower seal consists of two o-rings, a shim and a shock chaft guide, they are either Nylon or Delrin.

Specs
Front shaft - 42.5mm
Rear shaft - 51mm
Piston Diameter - 9.9mm
Piston thickness - 2.5mm
Piston Holes - 2 hole - 1.4mm

The threaded adjuster comes with an o-ring, to stop unwanted vibration adjustment.

The shafts are a smooth fit in the o-rings, and do slide in, rather nicely too... silky even.

Filling them is pretty simple, although the process of how much oil, what oil and how to bleed them, is completely lost in the manual.

1. Assemble shock cap, with diaphragm
2. Fill shock to top
3. Pump piston to bring trapped air to the top
4. Top up oil, to top
5. Fit shock cap, wind in, then back off, one turn
6. Push piston in, to get right amount of rebound without over-pressurisation of the shock
7. Tighten shock cap, clean oil

Shock should feel pretty sweet after that, I am trying 35wt front, and 30wt rear for now.

http://i82.photobucket.com/albums/j271/DCM71/Ansmann%20Pro-X%20build/Shocks/IMG_0205.jpg

The shock piston tops also come with a bleed hole, drilled into them, this made filling and bleeding, to get the correct re-bound on them, far easier.

http://i82.photobucket.com/albums/j271/DCM71/Ansmann%20Pro-X%20build/Shocks/IMG_0206.jpg

The kit springs are a little soft, but after measuring them, you can get away with using B4 springs, I grabbed a front and rear, and tried them on, kit springs on the left, B4 ones on the right.

Got the wheels out, kit doesn't come with any tyres, which, I think, is a good thing, cause most of the time, you never ever use them. Wheels, not to sure what they are made of, they are shinny, white (with what looks like either a red or pink tinge), they are well braced inside, and also come with vent holes too.

Front wheels, do not tighten too tight, as the bearings bind, due to no internal spacer.

Just gave mine, an initial shakedown, outside on the grass, very well behaved so far, diff hasn't slackened off, the slipper does accept small adjustments.

Only thing I will do, for now, is to add some lead weight over the front, to stop the front going light, under throttle.

Am enjoying watching this build, good work DCM :thumbsup:

Theres no doubt its a near on carbon copy of an RB5, is that legal? :lol: Using the origional style rear end rather than the new SP, not a bad thing though, i've never been convinced by the worlds rear end on the RB5.

The only down side to the origional RB5 rear end was that it was far to narrow in the box so it will interesting to see how the Pro-X measures up?

Looking good though, an RB5 with green bits rather than blue and £100 cheaper :thumbsup:

I find it's not that cheap after all (googled prices...)
RB5 165£
B4FT 175£
B4s 135£
proX 133£

B4s comes with tyres, proX does not, right?

It's the madrat(50£) that is better value (any review of that one around?)

Thanks DCM for this review

I leaning towards getting a Ansman magnum rather than keep waiting edges for the Kyosho RB5T;)

Like the FT car though it at least has Threaded shocks, Graphite components, stronger turnbuckles etc.

Either way, i'd say the X-pro is cheaper, and having heard about the upgrade parts that are coming they're going to be very cheap too!

Fabs
29-06-2009, 03:14 PM
The RB5 used to retail at £160 it's only due to the exchange rate that as sent it to £240+. But you would expect Ansmann to have simlar issues in todays climate? Where are they based?

They have done well to price it at £139, on the face of it the quality looks good. So does the design with it being so close to an RB5 its fair to say it will perform well.

No doubt about it a lot will ride on the shocks as to wheather the Pro-X cuts the mustard.

Just a few pointers here

Ansmann have obviously saved on R&D by blatantly copying the RB5, making a couple of changes here and there, et voila, cheap car because you've not spent months and months testing different solutions etc...

Kyosho make a point on producing everything in house in japan, which is why with the massive drop in the value of the GBP (and simultaneous ncrease in the value of the Jpn Yen, I am here comparing both to the dollar), the Kyosho kits could no longer be sold at the prices we'd seen before. The good thing is that the quality of Kyosho kits is excellent and consistently so.

I suspect Ansmann are producing in a cheap labour country that hasn't got such a strong currency and probably deal in dollars.

DCM
29-06-2009, 03:22 PM
Fabs, Ansmann are not producing the kits, more 're-badging' from another company.

Fabs
29-06-2009, 04:19 PM
Dunno where you got the korea thing from. I was told by a very reliable source that Kyosho kits are produced in Japan.

It IS a RB5 copy there's no point arguing about that. As i said, they changed one thing here and there but that doesn't cost anything, what costs money is the R&D and I can garantee there has been no race testing at high level to prove the design. Well there has been, but it's been done and paid for by Kyosho...

Same exact issue as has been seen on RC Tech with the 416 copy made in china apart froim here the car has been changed so it's not exactly the same so as to make sure there is no copyright infringement.

Steve, I know they're only rebadging, it's still most certainly produced in a cheap country...

DCM
29-06-2009, 04:23 PM
it is a HK company, so Korea or around there, like most RC Car kits these days, dude.

I don't think I have denied it is bares a very close resemblance to the original RB5 either.

Fabs
29-06-2009, 04:29 PM
Lol I never said you haven't...

I just tried to answer a question that was, how did they make it so cheap, in a complete manner, especially after the price of the RB5 has been quite substancially increased recently.

In any competition kit a good part of the price is R&D, testing different solutions, paying engineers and drivers, paying for private testing at facilities (that aren't necessarily in the country where those people who will test are, they might even be from different countries), entering high level competitions etc...

This, Ansmann (and subsequently the company that produces the kit) did not do or have to do.

29-06-2009, 04:32 PM
but they have had the balls to CAD design all their parts, machine moulds, and invested in good quality materials... so there is something.

Well,

With a caliper and an RB5 I can draw a car like the Pro-X in two weeks... Not much of an investment there.

The tooling and all, yes it is expensive but only a part of the cost of a car, it's all a global thing and certainly the lack of R&D is for me what allowed them to make it cheaper.

DaveG28
29-06-2009, 06:05 PM
If the madrat has the same dimensions, just a different material, then most tools/moulds are presumably used for both the pro-x and the madrat. As I saw a quote from Ansmann saying they had 3000 Madrats i Europe alone, then I am guesing a big part of the cheapness is they can amortise the fixed costs of said tooling etc over a larger volume (R&D also). Plus you have the truck versions etc.

I'm not aware of a kyosho version of the madrat (eg cheaper material rb5), or for that matter the Losi, though correct me if I am wrong??

And just one thing Fabs, if its a copy of the rb5 and also a copy of a losi chassis and b4 rear, erm doesn't that kind of suggest Kyosho cheapened on r&d too as they must have also copide the losi chassis/b4 rear musn't they??

Si Coe
29-06-2009, 06:15 PM
To be honest, even without calipers I reckon I could draw up a reasonable 2wd car in no time at all. I mean you go on about it being a copy of the RB5, but lets be honest the Kyosho isn't exactly wildly different from the B4, or the XXX before that. And the XXX was very similar to the XX, and the B3 etc.

Modern 2wd race cars work on the basis of a few very simple principles and it results in very similar cars. As long as I incorporate these features into my design it will be competent car, even if not an exceptional one.

The same tricks have been used for cheap 1/8ths, and TC's too.

The only difference between what Team C did and Kyosho is that Kyosho then take the basic design around the world and test it, making lots of tiny changes to make their buggy not just 'like a B4' but 'better than a B4'. Team C simply marketed their largely untested creation.

The result is that Madrats and X Pros are suffering from T-Piece breakages because they weren't tested on UK tracks and can't take the conditions we race under. Ansmann are addressing the problem, but were in effect using the paying customer for the R&D.

DCM
29-06-2009, 06:16 PM
In the end, we could say, there are traits of the DNA of the ubiquitous 2wd layout, in all the 2wd buggies. And there is only so many variant on a theme before you get very 'similar' designs.

But, I don't mind talking about it, as it keeps this thread active, and keeps interest :woot:

So, do we go down the route, that no other car company should use the XX4 front suspension layout.... I also don't see people saying... hell, the D4 shouldn't be made, as it is a copy of the B44, with some changes, which is a copy of the BJ4WE, with a few changes....

Although, to be fair, Associated did a deal over the BJ4 didn't they?

I'm not that comfortable to be honest with some of the posts here saying it should just be a free for all. The other poster was right, would you still think that if someone nicked an atomic design? Or to stratch the analogy, if a competitor did it to the business you work for, meaning jobs were lost etc (I realise its not the case here but its the same principle).

And Jamie, would you still agree if Dinball just copy the ansmann and undercut you, rather than selling the same car?? You'd be fine with that presumably??

Having said that, its clear from the contradictory claims that it doesn't just copy one other car, and it does have its own moulds etc, and it does seem accepted practice in rc to start prototypes by using other companies kit then keeping the best bits and remoulding it yourself etc, so I don't see how Ansmann have done anything different to any other rc company..

I know, but it was mean't as a "what if". If they went out and made your car themselves but cheaper doubt you'd be so keen on it being a dog eat dog world. In fact it is strange that them importing was soooo bad whereas copying is supposedly all ok, given that both give people what they want (the same car but cheaper) thats why I highlighted it!! Both are covered by laws etc.

Having said that, AGAIN, I don't actually think the Pro-x is a straight RB5 copy. Otherwise there'd be an rb5 t-piece to use to fix the issue!

I personally dont believe in "1 rule for one, 1 rule for another" way of thinking. So if Dinball did make a car that was an Ansmann or Team C copy, then thats up to them. I would be a total hypocrite if i was to say it wasnt on.

Exactly, you hit the nail on the head there! It can't be a copy of a Kyosho and B4 unless the Kyosho is also a copy!

For me, once your doing your own mouldings/mounting methods etc etc, even if based on an existing concept (even closely), then it's fine. It's when you just exactly copy it becomes dodgy!

No,

There is a difference between using proven solutions to create something new and copying a design.

Yes the RB5 has a rear end very similar to the B4, and a front end very similar to the LOSI. But they are in no way identical in the way they're built. You WILL NOT be able to put any part from the RB5 on the B4 or XXX-CR.

For example, you mention the gearbox of the B4, but the RB5's won't fit on a B4. I can garantee the Ansmann gearbox will fit the RB5, and if it doesn't it'll be so close you might be able to with a little bit of work. As a matter of fact I wouldn't be surprised if you could slap the ansmann's entire rear end on a RB5 T-plate (with the scception of the rear motor guard whic is mounted the other way round). And same goes with the front.

The Ansmann is plainly a knock off RB5, 60% of the parts will fit the car, it's built in exactly the same way, only on some of the parts changes were made, mainly screw holes were moved.

Now there's nothing wrong with ansmann filling up a market segment left open by Kyosho (who haven't released a cheap RB5 let's face it), but don't go tell me it's not a blatant copy.

And for the record I am repeating myself here and it's starting to annoy me how people read whatever they want to read. I only pointed out why the car can be so cheap, not knocking the car off in any way. So if you have any further comment about how it's not a copy just keep it for yourself.

In all seriousness to fix the t piece problem then, why can't an rb5 t piece be used? Different hole positions or something??

I believe thats already been tried.
They don't fit.
Because they aren't the same as the RB5.
Because its not a direct copy.

(this is getting a bit dull....)

The holes to mount the T-Plate on the chassis are in a different place, it's "only" the part behind the front suspension mount that is identical.

Same goes for the parts that mount on the front of the chassis to make up the front end, they have different holes positioning so that some people can say it's not a copy.

Pack it in, FFS, I couldn't care, if it was a copy or not, whether it is close... or not, to be honest, this is detracting from the car itself, but going down the plagirism route.

In the end, yes, the car is very much an RB5 re-jigged, no, RB5 parts wont screw on, but I bet the wishbones would fit, I know my DB-01 wishbones fit, on the rear... I don't give a fig tough.

Ansmann X Pro - Team C 2wd - RB5, all very similar, lets just get over arguing about it. No matter what we do, or say, the car has been based on the RB5, when I built mine, I was referring to Jimmy's review of the RB5 and thought... yeap, the same, but different.

just starting to build up my ansmann x-pro truck kit, and noted some small things here :
- diff gear is the same as RB5's
- idler gear is NOT the same as RB5's
- diff ring is the same size as Xray touring cars'

on a side note here, i noticed the shock piston's holes are drilled with a tapered shape on 1 side which means it has a concave shape. so which side should the piston with a bigger opening face, shock top or shock bottom? and why? pardon me for asking these questions here as i'm a noobie in offroad...;)

pistons are probably moulded, and the taper is a result of that, and it doesn't matter which way up/

the pistons are white teflon pieces, not molded types.

still, there is some people who will say, that it is a tuning option, in the end, the oil still has to pass through the small hole, so flow rate is the same, which ever way up, it is.

But the coefficent of discharge will not be!

Start with the small side of tapered hole uppermost

but as the fluid has to pass a restrictive hole, and as a fluid is not compressable, it will flow at the same rate.

care to explain a bit more on this, what's the rationale behind this vs using big side of the tapered hole uppermost? thanks...:)

co-efficient or not, fluids are not compressable, so will still only pass through the piston hole at the same speed.

Some fluids are compressable (depends on system pressure obviously), although shock oil @ pressures in an RC shock isn't one of them.
Edge condition has an on instantaneous flow through orifices, a principle we often exploit in my line of business. Remember the oil flow around the shock piston is highly transient.

also a fluid traveling through a hole that tapers down,cant be compressed so it has to accelerate,and a fluid going through a hole that tapers out cant expand so its must slow to fill the same space,IE taper small hole facing to wards the top of the shock will have more pack, than the other way round.

this is what i thought too. so i installed the tapered small holes facing the bottom to have a slower rebound, hope it works at our local track which is currently a smallish technical dirt track and not too bumpy.
