Upcoming Review – Yokomo MR4 Drift Chassis

Almost every RC drifter will have heard of the the MR4 chassis from Yokomo, and as it’s belt driven some will prefer to a Shafty like the Tamiya TT-01.

However, the purpose of getting this chassis is to make an almost direct comparison with Belt Drive and Shaft Driven – what are the advantages and disadvantages of each and how much do they cost to run are some questions you’ll find answered.

In order to do this, both cars will be set up with exactly the same component and final gearing (time for a calculator….) and then tested side by side whilst being filmed – in true battle drift style! I’ll then post the results up with pics and videos

Just as a side note, the Yokomo MR4 was bought for £35 ( $65) off eBay and comes with a new RX7 body shell, motor and servo – that’s a cheap entry point to drifting!

Here’s some pics of what’s on it’s way;

3Racing Swing Shaft with +5mm Offset

After being frustrated with adding washers to push the wheels out to fill the rims….and it still not being quite enough, I decided to go for these 3Racing Swing Shaft with +5mm Offset.  I intend to use them with some dress up disc brakes and some 0mm or 2mm offset wheels to get a decent drift look.

I’ll also post some pics experimenting with 190mm and 200mm bodies to see just how far you can push the rims out with these swing shafts.

In theory, up to 15mm is possible with these and +10mm offset wheels!!  maybe a little much……….

I’ve ordered them from eBay seller ToyEast whose shop is here

The 3Racing Swing Shaft with +5mm Offset are here

Pictures below show the shaft, and also a metal collar that will no doubt go between the wheel and suspension arm.

GPM Drift Alloy Suspension Arms for TT-01 – important update!

Saw these parts on eBay and thought they are an essential upgrade for any TT-01 drift machine, however, not all is good so read on…..

UPDATE: Ensure you have the TT-01D chassis for the parts described below.  I have a few TT-01 and TT-01E chassis but the LOWER ARMS WILL NOT FIT! They are a different design, look really closely at the pics for the LOWER arms on the eBay links below.

However, the UPPER ARMS DO fit the TT-01 and TT-01E chassis.  So far I haven’t found they offer much in the way of camber, possibly about -2 degrees, which is good for racing…..if you just want to show of with -10 degree of camber these aren’t the parts for you!

Now for the even worse news.  I order two sets of the Upper Rear Adjustable Arms as I have two TT-01s I wanted to fit them to both.  The front adjustables work fine as above, but really don’t offer much in the way of being ‘adjustable’ as above.

The problem with the rears is that as standard, they offer no more camber than the standard GPM Upper Rears Alloy parts, and when you try and adjust them you will find you can’t.  Due to the way they are made, similar to the plastic version, there is a centre screw holding the two main pieces together and you are supposed to just tighten it all up – and this is where it goes all wrong…..

The problem is the alloy is weak by it’s nature, and the screw is of poor quality, so once you start to tighten to get the camber you want, they break with little force.  I then tried to saw the ends of the screws so they’d end up shorter and therefore offer more camber, I filed the ends to make sure they would go smoothly in.  Started off with no problems and then the main piece just threaded…….first piece of junk created.

I then tried tightening the screw, which itself is an issue since it’s only 3mm, and there aren’t many 3mm spanners around my house at the moment and again, things just went wrong with threading issue.

After that it was just frustrating, you can’t screw these far enough as standard, if you try and modify the parts are too weak to cope with it, and when you modify the results are awful.  I tried 4 different rear upper arms and only one work to a degree, but even that’s threaded inside because the arms are at an angle.

Once I fitted the one that worked, the driveshafts then became a problem because once you push the camber in, they are too long.

Basically, this grade of allow can’t cope with 2mm screws, it’s just not strong enough, and the middle screw isn’t one of high quality.  Even GPM’s pic below shows the Uppper Arm on the right is bent!  This is a disappointment from GPM as everything else I’ve had from them has been perfect……

My plan is to now get a TT-01D and test the parts on that……..

Damage parts are below so you can see what happened, with the one successful one I made.

eBay seller UKRC has the cheapest parts and delivery, I’ve used them in the past and the delivery is fairly quick too.

The Upper Rear Adjustable Arms are here, part code from GPM is TT057D

and the Upper Front Adjustable Arms are here, part code from GPM is TT054D

I have seen a set of lower adjustable arms for front and rear, but I will trial these first and see if they’re actually required……

Budget Drift Tires! TurboHobby DC-3 and DS-F2 Drift Tire Sets

Whilst hunting around on eBay I found these REALLY cheap drift tires, full review as you read on……..

Click here for eBay seller details and shop

This eBay seller is a really genuine and nice guy, these prices are amazing considering the tires themselves are actually very good compared against Tamiya drifting tires, which I find rather frustrating because they are expensive and slow compared with these TurboHobby versions. In fact, they’re so good I’ve just ordered more! The ultra high speed tires are on their way as I type so I look forward to testing them.

Full Description;
Turbo Hobby DC-3 Drift Tire Set
DC-3 compound is for Medium speed drift.
DS-F2 compound is for medium/high speed drift
Made from injection mold.
Rounded & polished edges for better drift on corners.
No glue require to install.
Compatible with 24mm width wheel

Fitting;
Both types mentioned are easily put on the rims, but I found that some ‘encouragement’ was needed. They are such a tight fit that it meant leaning my whole body on them but they went on in the end – so that’s what the ‘no glue’ bit was about……! Also, I noticed some trimming maybe necessary on the inside of the tires just to get a flush fit but this is not an issue, especially at this price.

Driving;
I tried both the DC-3 and DS-F2 on a TT-01 with a 15T motor and another one with a Brushless motor that’s equal to a 5T. Both gave very predictable handling on tarmac, and the different compounds suited each car meaning the Brushless TT-01 was drifting in huge arcs, and the 15T TT-01 was great for tighter corners. It’s great the multiple compounds are available from the same manufacturer as it will make it easy choosing which tire you need for different surfaces.

Incidentally, both were tried on carpet and given the space I was in they were WAY more controllable than the Tamiya drift tires, so bear that in mind if you drift indoors!

On the car the they look great, and I’ve added some pics below to show what they look like on the cars, along with wheels you can get from the same eBay seller here.


Slidemaster 37R Drift Wheels by Speed Way – Volk Design

These have arrived from eBay seller Topsecret0304, and a lot quicker than I thought!  Once out of the pack they are excellent, the moulding is top quality with no rough edges and they don’t feel like they will break just by looking at them!

I’d recommend these if you are keeping with a 190mm and want to fill the arches out, if you are looking at getting a 200mm bodyshell, then you’ll also need to extend the drive shafts with something like 3Racings 5mm offset shafts here

Ansmann Racing Drift Tires

Here’s one of the many drift tires available on the market, however, this one is cheaper AND works really well…..

Although it takes a good few uses to get it to it’s optimum point, where the plastic rings are just about worn down to near the rubber wheel itself…….at that point you get an almost perfect drift tire for use on tarmac.  It gets you sideways nicely, but is really controllable…..a great budget compromise.

Here’s some pics of new ones……

And here’s some on the right about to get ripe…..note the two raised sections, they’re made of hard plastic that wears down

If you compare the new ones above and the used ones below, you’ll see it takes a good few runs to get them to their best.
