Re: Marui Samurai 4WD - Another SilverTriple's journey...
Changed the faulty servo... 2 hours work
Did not unmount everything :
- removed the sprocket first
- removed the underside guard and bumper
- removed the roll cage in one part
- removed the front spring tensionner, and middle part
- unscrew the front cell
- changed the servo
- remount everything
My Samurai is back on track. This car has never been thought for maintenance, for sure

Re: Marui Samurai 4WD - Another SilverTriple's journey...
@Dadio , last time I ran cars at my club I did broke only a servo... You said I did not try hard enough !
I did a quite violent run with the Samurai this morning...
https://youtu.be/DOEYWAnugsw
The nylon wing did not survive the run. The rest of the car is safe, and the chassis is intact. Although I did encounter an additional issue with the pivot ball leaving the rear right arm a few laps after the previous fly, and having the car stopped with a dogbones lost on the ground... The OptimaHouse parts are validated, they all survive this run.
Beside this I also had a non functionning servo on the Spider TF3, for an unknown reason as it was working perfectly fine last time... For this time, my son did not broke anything. Not too bad, actually. We left at 12:00, while the temperature was already above 30.

Outch !
If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.

Re: Marui Samurai 4WD - Another SilverTriple's journey...
Since those were missing in the CAD collection, I modeled the Samurai tires...
They are quite similar to the Ninja tires in the spirit, somehow, but require a heavier timeline in CAD software... Ultimately, it did not took much time to complete those.

Re: Marui Samurai 4WD - Another SilverTriple's journey...
I got recently some Samurai left over parts. Among those there was two motor plates...
I needed to rework my motor plate, as it is the basis for the gearbox. After doing measurements, I decided I would proceed differently and redo it from scratch.
I took a picture, applied a Canvas, calibrated it and did it from there... I don't like this way of doing, but it gets the things right.
Then I took the time to look at my two plates. There was two versions of the gearbox and as well two version of the motor plate. Except one hole (circular on one side, and slot on the other side), everything else match.
I did stop working on the chassis when I noticed some measurements of the gearbox were wrong. And until I got those two motor plates, I was not able to measure anything as the Samurai n°2 and N°3 are not in parts yet... And the Number 4 was missing most metal parts. At this stage I succeed to get axles, outdiffs, motor plate, roof, and some other small parts. I still need to find a shaft set, big bevel gears and a central diff so I would have everything to work out a N4.
In the meantime, the motor plate being right should allow me to restart back on the Samurai model, starting from the gearbox (which I need to redo - not sure a replace component would work for this). But before this, I'll print a motor plate for a safe check.

Re: Marui Samurai 4WD - Another SilverTriple's journey...
Thinking about my Samurai N°4 which is still in parts and incomplete currently...
Missing elements are actually very few :
- Center differential
- Sprocket
I'm thinking now that based on what I have done with the Ninja, I have already a good part of the Center diff already : the main gear is a derivation of the rear diff gear, and for the big bevel gear, they would be easily derived from the rear diff big bevel gears... So this should be easy to pull a model for Samurai center diff (I could cheat with an aristo craft hitec Kangaroo's spooler, but that would be no fun )...
Then it would remain the sprocket... I need to find data on how to design one, so if one has a lead to design information of the sprocket, I would be interested

Re: Marui Samurai 4WD - Another SilverTriple's journey...
I had this in mind for quite a while... My Samurai tires were too Tamiyaish. I had to do something. And I wanted some tires I won't care to deplete if I run them...
Few months ago, I did a CAD model for the Samurai tires... I had this in mind for quite a while... I got new printers, and it allowed for new capabilities
And then, after few prints
Time to show off...
I love the Samurai, and this one is a very unique model...

Re: Marui Samurai 4WD - Another SilverTriple's journey...
As I want to test the tires, and I don't want to glue them on rims, I've reprinted rils with rings to have the tires maintained in position...
I've some hope it will be fine for testing the tires a bit at least. I may end up gluing them, but I would like to preserve the possibility of doing another test run with printed tires done with different resins... The weather is very changeant here, so I may not do the test run now and wait there is bit of sun for this...

I may not be the best at this...
I could have probably made it cleaner... but this is the first time I'm doing this, actually...

Re: Marui Samurai 4WD - Another SilverTriple's journey...
I remember having an argument on lettering the tires or not, and lettering the tires with a very simple font instead of trying to reproduce the original Marui font...
What do you think?

Re: Marui Samurai 4WD - Another SilverTriple's journey...
I could not resist... The weather is not good, but trying to run on asphalt is not requiring too much of cleaning afterwards...
For memory, I printed 7 Samurai tires in total : 4 fronts and 3 rears. Two of the fronts (one of them which was lettered) had an issue due to cup suction effect, and there is a small cut on the side of the tire (you can see on the A of traction which is having a mark on the previous post). I've mounted the other printed fronts (with a hole in the thread) for the test run. The rears were not affected to the same level, so they are good to go. The rear seems to be seated properly, while for the front, I may need to review them slightly to get a better seating. In the meantime I put some double face tape in the slot to ease adhesion...
I started by running slowly inside, and it seems good : it grips nicely inside. Let's go for asphalt for a very short run...

- it grips to the point I need to glue the rear

Re: Marui Samurai 4WD - Another SilverTriple's journey...
I took some time to add a minor detail to my Samurai tires...
And I did that on tires which are targeted to run...
