@Billy: Thanks, you know we have here a full island of "peasants" speaking English ;-)

@Sosidge : Mine is still a shelf queen. I do have the intention to test it on our track but the weather is quite bad for the moment.. :-(

If you ever do test it in the wet let me know how it goes. I quite like running my fwd in the wet.

Aw yeah!

... I'll probably build it tonight too. 21.5 motor? I think that's the way to go. *grins* VTA tires?

I’ll check to see if any update on mine. 21.5 is what I was thinking, leaning towards the RWD setup. I do have a 25.5 in case

edit. Again no update on shipping. I’m expecting another week.

Well it arrived, but I was to tired to do the build last night. I wonder if I have the right paint for the body...

You're not wrong. Where can I get that decal set, without giving my blood to tamiya.

I built mine tonight. Lets.. talk...
  • Comes with tools! And Grease
    • The allen keys are soft... don't use them.
  • Comes with nice wheels.
  • Comes with fittings for wider track.
  • Comes with a 380 size motor adapter.
  • Comes with pinion.
  • Comes with bearings.
  • Extra fasteners, and bearings. Things you might lose.. you get spares of.
  • All the parts to setup as FWD, RWD.
  • Comes with Setup Sheet
  • Manual shows how to adjust camber, ride height, and roll center.
  • Includes a really nice Civic body, with all sorts of body accessories, and a wonderful sticker package. It's Tamiya grade.
  • Can be setup for active rear toe.
  • Has universal joints.
  • Full size connecting rod diagrams.
  • Centered servo position.
  • Comes with a good servo saver.
So it's not all sunshine and gumdrops in this world.
  • Switching configuration is nearly a complete rebuild.
  • The chassis is quite floppy.
  • Plastic motor mount.
  • Hubs are over-sized to accommodate brake calipers.
  • The servo needs it's ears clipped, and to be taped in.
  • Wheel hexes are also brake disks.
  • No damping.
  • Cheap bearings.
  • Cheap universals.
  • No turnbuckles.
So... I'm pretty happy with this. I think I paid $143 shipped.

It's 11pm now. I started building it around 8. I probably built it in two hours, including having my daughter "help" me. My usual speach of buying a M3 thread forming tap, stands. Buy one, it helps. This model uses a lot of m2.5... which is something I can't find a thread forming tap for.

Reading the manual made me quite confident in the build. The only "tricky" bit, is how they did the exploded drawing of the diff wasn't clear where the spring, and thrust bearing pack. Those go inside the axle, instead of in the drive cup.. just so you know. It's got color, and it was easy to follow. I was very impressed with the manual. It doesn't though, show how to do the other configurations, like a tamiya manual typically does.

While assembling a car, the screws matter. And the fasteners are of middling quality. The bearings are "so-so" They're shielded but not sealed. And quite narrow. I have questions about their reliability.

The suspension is interesting. It's got kingpins on both ends. The bottoms are well designed, and have a spherical bushing that the kingpin then slides in. The control arms, up top, all are almost slop free. The knuckles drop freely, which is a really good sign. Most of the suspension is symmetrical, so to have a complete set of suspension parts, you need two knuckles, one upper control arm, and one lower arm. To change the springs, is fairly easy, one screw per corner. But it's a 12mm screw... That screw also reinforces the sliding part of the kingpin.

So, lets talk about tuning. To adjust ride height, they say you should put shims under the bulkheads. That's a common thing, hopefully the screw spacing is "normal" and we can raid 1/12 scale supplies for fine adjustment. Roll center is adjustable by putting shims under the upper ball joint. You can also tweak active caster by putting different spacers under the front and rear of the upper arm. Camber is adjustable by putting shims between the lower arm and the bulkhead.

MST has a full spring set, with.. six weight of spring. (One came with my car..) They also have a metal motor mount. And a metal diff set.

The car seems setup, to allow for some cross chassis supports, to account for how floppy the fiberglass deck is. There are holes on the front and rear support cages that could have bridges bolted in place, and some holes on top of the cages for a bar go run the length of the car. Now.... how do we address damping

So... we'll need to see how the car works. And do some research on working gear combinations. It's got two motor positions... but between swapping spurs and pinions that does give us a lot of range to work with.

Aaand, I wrote up my review.

https://realtinker.blogspot.com/2018...car-sorta.html

Highlights:











The car, empty, is 337g. That's... like 1/12 scale light...

Nice, simple car. I like it Looks like lower "arms" could be converted to some short damped arms with some work.

I really like how simple the chassis is. Direct drive is something I'd like to try, as I had helped a friend rebuild his trf104 f1, the car was super quick but oversteered all day.

I wonder what a RR of this car would drive like. Dampening is my only real qualm with this chassis. I love setting up suspension. But the lack of dampening is probably the only thing that has me hestiant.

How is the diff? Does it slip? I can see this chassis being a really great parking lot and street basher. If the chassis really only weighs sub 350g then it's going to be stupid fast. The fact that it comes with the greatest Civic body of all time really helps my case for getting one.

I can see mst releasing all sorts of upgrades for this. I can see people running dual motor setups. Or somehow making it a 4wd with a belt... At least those are some of the ideas I had when I saw the layout.

How much ride height does it have? Could you fit mini or f1 wheels/tires on it?

I haven't actually measured ground clearance yet. I suspect mini wheels might be a bit to short for it. I have some F1 wheels hanging around, I'll try some rears, and see how that goes. if that works, we're looking at ~all the traction, ever~ on this car. Hahahaha.

The diff can be setup to slip, or not. It's the usual ball diff fare.

Damping may come in the form of the 1/12 scale answer. 20k diff fluid on the kingpins. :-) Or... there's the EuroTruck/Tamiya 4wd technique. "Rattle damping" Where you leave some weights loose on the chassis, and any vibrations get sucked up in the interaction between the two main masses of the chassis.

I'll run the car this weekend. I'm as curious as you are.

The chassis really is 337 grams.

Nice set of springs... I've seen it was included in the RCmart offer... I hope we can find them separately soon...

I just built the car. With no special effort for weight savings, the car is 1154 grams. No body clips or transponder. I could knock 100g off with a battery change and servo change....

Things that could be done: super shorty battery, a plastic case servo, a short servo, an esc that's not half aluminum block, and a lighter motor...

This thing is light...

So the stock spur is 75 teeth. Stock pinion is 15. That's 5:1. Not good for most "slow" racing. I need to hunt down a 70 tooth spur and a 20 tooth pinion. That should be about right for 21.5 and fwd.
