Samix Xray T4’19 Carbon Chassis

Following on from the Samix Yokomo BD9 chassis I looked at yesterday, here’s a look at some other new products from Samix.

T4-19-1001S Xray T4’19 Samix 2.25mm Carbon Chassis (soft material)

Even though the description says ‘soft material’, the chassis is not overly soft. It is cut from the usual Samix carbon fibre that has a matte or satin surface finish, and the quality is excellent as always.

Specs:
Width: 86mm
Thickness: 2.25nn
Weight: 68g

The chassis has holes for the T4’19 specific front alu stiffener, but also holes for optional Samix screw on weights at the front.

The screw on weights are available in 5, 10 and 15g versions. The weights are made from brass, but beautifully finished in black, and sold in pairs.

T4-19-4070-5 Samix for Xray T4-19 front balance weight 5g (L/R each)
T4-19-4070-10 Samix for Xray T4-19 front balance weight 10g (L/R each)
T4-19-4070-15 Samix for Xray T4-19 front balance weight 15g (L/R each)

Samix also have these few other bits available for the T4’19:

T4-19-4072 Xray T4-19 brass motor mount plate

Samix Yokomo BD9 Aluminium Chassis

A quick look at the recently released Samix Yokomo BD9 Aluminium Chassis.

As I mentioned after I had run the Yokomo BD9 the first time, I wanted to also test an aluminium chassis on this car. Now when Samix announced their BD9 alu chassis, I thought it would be interesting to try that while still running carpet this winter.

BD9-7001 Samix Yokomo BD9 Aluminium Chassis

Samix product information for this chassis mentions these features:

1) Smaller cut outs, stiffer chassis
2) Cut outs designed to reduce vibration
3) Made by high quality aluminium 7075-T6
4) Black colour anodizing with nice chamfer finishing

Here a few more details:

– Thickness: 2.0mm
– Width: 85mm
– Weight: 91g

That means it is the same width as the standard BD9 carbon chassis, but 23g heavier.

The finish is excellent, as it has been on all Samix products I have tested throughout the years. The chassis is absolutely flat, and has a nice satin black surface.

I will be testing this on my BD9 in the coming weeks. Look for a report on testing in a not too distant future.

Samix also offer a few other products for the Yokomo BD9. You can check them out here.

Early 2019 Body Tests

After last weekend, with a lot of focus on new bodies at the ETS Round 2, and also personally testing bodies again on a new track layout, I thought maybe it’s finally the right time to write something down.

As often before, I planned to write something about this subject already earlier, but as always the amount of time I can spend on this blog is pretty much decided by what other things I have going on. Anyway, I’ll try to sum up a few things finally.

Just like the last few winters, I have had access to a local carpet track. This time from November to the end of February, so still a little bit of time available.  Since I have been mostly running the TRF419XR, which I know well from last winter and have well setup, I have spent a lot of my time at the track testing bodies.  Personal special interest and all that…

Last weekend I did another round of going through all the bodies I have, back and forth, as there was a new track layout fairly different to the last one.

Lots of bodies to test, but still a few important ones I missing that I did not have a chance to test.

kb_bt_100219

Latest track layout. The area is around 25x14m, direction is always counter-clockwise, and the grip is usually low to medium.

kb_tl_100219
kb_tl_100219-2

Earlier track layout.

kb_tl_0119-1kb_tl_0119-2

Maybe I should write down the main impressions for each body…

First it is important to say that I run indoors to ETS stock class “rules”, i.e. Muchmore V2 13.5, blinky, 5.0 gearing and 1320g.

Please also note that these tests were all done on the small carpet tracks seen above, so how the different bodies work will be different on a race size carpet track, and of course totally different outdoors on tarmac.

Protoform Mazdaspeed 6 – We all know this body. Can be pushed hard, but found it lacking compared to the new bodies on this small size track. Still not very far off though, but would need a larger track to excel.

Protoform Type-S – Very stable in high speed and when you touch kerbs, good steering of course, but still not one of my favourites in these conditions.

Protoform D9 – Lots of steering! Fastest over 1 lap always, but never over 5 minutes. Needs more rear grip.

Bittydesign JP8 – Again a surprising amount of steering. Fast laptimes but not really consistent over 5 minutes.

Bittydesign M410 – My favourite from last winter, and still one of them. Always consistent, but with good steering. Always fast over 5 minutes.

Mon-Tech Racer – Almost always works. Good balance. Not always fastest over 1 lap, but fast over 5 minutes.

ZooRacing Zoozilla – Struggle with the balance with this one. Did not manage good runs.

ZooRacing Preopard – Always keeps up momentum and gets around the track very fast, even though my lines are not always the prettiest with it. Always good over 5 minutes.

Aerox Razor – Well, that did not work.

Remember that all these are just my impressions, on my car, on these small carpet tracks. To really compare them you would need to spend weeks at the track, comparing different mounting positions and adusting the setup. Also remember that even with my simplified testing, the difference in 5 min results is mostly quite small between all bodies.

kb_zoop_100219

With that over, time to conclude what I have found.

On the earlier track layout I had three favourites; the M410, the Racer, and the Preopard. However, on the newer layout, the Racer dropped out, leaving the M410 and the Preopard as my overall two favourites so far. Very different in looks and how they feel on track, but both work.

With the recent success of the Preopard (and DBX), it’s funny that the first thing I said after the first run with the Preopard early this winter was “the pros will like this body”. Turned out to be right…as first impressions usually are.

kb_bdm_100219

Here are my two best runs last weekend, and they were indeed with these two bodies.

Session 7 is with the Bittydesign M410.
Session 8 is with the ZooRacing Preopard.

Obviously I had a couple of bad laps in the middle of the run with the M410, but not much in it…innit.

kb_bt1_tl2

Of course there are at least two obvious bodies missing from my tests, in the Bittydesign JP8HR and the ZooRacing Dogsbollox, but I did not get my hands on those so far.

Xray T4F – Coming Soon

Great to finally see the FF class gaining more and more momentum!

TRF HG Alu Screws & Wing Washers

A quick look at some of the latest small TRF releases.

The new Hi-Grade aluminum screws we just recently added to the TRF product line-up, and are so far available in 4 different sizes.

42327 3x6mm Hi-Grade Aluminum Hex Head Screws (Blue, 5pcs.)
42328 3x6mm Hi-Grade Aluminum Countersunk Hex Head Screws (Blue, 5pcs.)
42329 3x8mm Hi-Grade Aluminum Hex Head Screws (Blue, 5pcs.)
42330 3x8mm Hi-Grade Aluminum Countersunk Hex Head Screws (Blue, 5pcs.)

These screws feature a larger/higher head, and therefore a deeper hex, and finish/looks is superb as you would expect. I decided to exchange the upper deck screws (which were starting to show wear) on my TRF419XR  for these, as they are used a lo

Round head and countersunk HG screws holding the rear tower. The countersunk HG screws also feature a deeper hex, just like the round head screws.

Also recently released from Tamiya are these alu wing washers.

Surely the nicest wing washers on the market! 🙂
Includes 3x8mm titanium countersunk screws.

First Yokomo BD9 Run

Last weekend I did a first few runs with the Yokomo BD9, after I during last week finally took time to install everything and set it up. I planned to write this short update right after I got home from the track, but it got late, and I have been busy. Same old story..

I run the BD9 after I had run my TRF419XR, so on the same conditions, same set of tyres, same body choice etc. Obviously my BD9 is the carbon version, while this winter I run and alu chassis on the 419XR, after running the std carbon plate last winter.

My expectations for the BD9 was that it would be very good on track, and those proved right. Straight away the car very much at the same speed as my 419XR, being only around 0.1s per lap slower. The car gave a good impression on track in every way. It has lots of steering, feels very free, and is very quiet. I wish I could test the alu chassis as well.

Anyway, I will surely do some more running with the car during the next month or so, even though the 419XR is my main car. Will be interesting to see what can be done with some setup changes. I will most probably report back at some stage 😀

Yokomo BD9 Update

Just a few pictures of the Yokomo BD9 I built earlier, now finally ready to test.

bd9r_2

With making the BD9 ready to run, I also decided to install the new Muchmore CDS10 Low Profile servo, which I have already had waiting for a while.

bd9r_3

Decided to use a Bittdydesign M410 ULT body to start with, as it is one of my favourites on carpet being very consistent over 5 minutes.
