…, what tires are those on the back?

The rear tires are Traxxas Pro-Trax 2.2 (4790R).

This project is still not done or dead, it needs only time like good wine :)

The body will be the next step and today I found time to cut/trim the lexan body:

Parallel I work on a new gear cover which looks more like the original cover respectively a mix between original one and the TTC gear cover:

Nice work mateB)

Will that gear cover fit the standard 2018 TTC gearbox?

Unfortunately it does not fit on the original (or TTC) motor plate due to a different shape compared to one of the TRF201.

Some progress in the gear box cover…first 3D print:

Nice! That looks like a bit of a pain staking masking job. More than worth it in the end though👍

@Kol__: The (hopefully good-looking) end result is the only light at the end of the tunnel ;)

The paint job is definitely not my favorite part of the RC hobby.

The 3D printed gear box cover arrived finally…

Mounted onto the drive train…

I also trimmed the original motor guard to fit onto the gear box respectively sub chassis plate.


And the chassis with the mounted drive train…

Now is only the body shell missing. There I have to paint currently the last color (white). Stay tuned…

I LOVE this thread! I need the stealth in my childhood Monster Racer for another RC10 build! Would LOVE to order your set up 😀

Ah mate, that final 3D printed gear box cover looks amazing, in particular when compared to that first 3D print. Lovely work, what's the little adjustment cap? Original TRF201 cap or 3D printed too?

It is the original TRF201 cap...so far still :)

Due to different design loops there is beside the „setup“ from my last post (3D printed gear case, gear diff, carbon chassis plate) a previous setup with the gear case from the TRF201 (original TRF201 gear case incl. ball diff, carbon chassis plate).

a807e55b-13a7-4e29-awmjnk.jpeg

The upper bracket is now also a professional 3D printed part (PA12).

@GTodd: Sometimes you have to part with things to be able to do/make new things. And maybe this could be also an option for you. Let me know… ;)

I like this one with the original Gear Box, any down sides to this one?

@GTodd: It's an original TRF201 gearbox and it shines blue...nothing else to say :lol:

I've tested this drivetrain this year in February in my lawn (with a 3000kV brushless system) and it performs excellent.
I don't know what's your plan with your Monster Racer, but in my opinion there will be earlier/first issues or cracks of the suspension/chassis/steering, before there will be an issue with the drivetrain.

The package will include the parts shown on the pictures below:

  • TRF201 gear box with TRF201 ball diff
  • Top bracket in PA12 3D print
  • Blue TRF201 motor plate
  • TRF201 motor guard
  • TRF201 gearbox cover
  • 2x blue aluminum spacer

For mounting the carbon chassis plate with the plastic chassis and the screws for mounting the suspension arms onto the carbon chassis plate, the original screws/nuts can be re-used. 

PM me, if you are interested...

That is some inspiring work. Love it. I have a 3D printer (Prusa MK2S) and have been fantasizing about trying to design some custom gearboxes for my SuperShot that use the TD4/TA06 dfferentials and a slipper clutch (maybe from a DF03). Seeing this thread, I am even more inspired to give that a go at some point.

Teaser of today…

What could be hiding behind this small cover? 🤔

Some sort of sexy differential?🍆😆

So the diff cover is 3D printed, how come only one of the 3 screw mount holes is there? Just for test fitting?

Not only a sexy differential, there is a sexy modified gear case behind...stage 3.

Once again summarizing...

Stage 1 - TRF201 gear case for TRF20 ball diff + mounting bracket on the top (2 fastening points with the plastic chassis) + new (carbon) chassis plate + TRF motor guard

f6c54b09-3163-4d48-a69jsw.jpeg

 

Stage 2 - 3D printed gear case for gear diff (TA06/FF03R/XV01) and ball diff (TD4 - but not tested) and with 4 fastening points with the plastic chassis + new (carbon) chassis plate + TRF201 motor guard

f2ec60d7-bd1a-a6e1-afsk6g.jpeg

 

And now stage 3 - Modified 3D printed gear case which used also the 4 fastening points with the plastic chassis but...can be used with the original FRP chassis plate and the original motor guard. No additional chassis plate is necessary.

I moved the gear case ~2mm up to get more space for original motor guard. Here a picture of the first test part:

The final parts will arrived next week and looks like this:

View from bottom side with mounted cover.

Same view with the removed cover. I decided to use a cover instead of increasing the gear housing to close the hole in the chassis plate.

Complete drivetrain.

Drivetrain without motor and motor guard.

Additional view from bottom side with mounted cover.

View from the right hand side - The gear cover plug is now also a 3D printed part :)

One month ago, since I started the painting work...:rolleyes:
Today I will apply the last color PS-1 (White), but first the progress of the last weeks step by step.

PS-5 (Black) done...

img_394396dzo.jpg

Preparation for PS-12 (Silver): Front grill, cooler housing at the back and the stripes on both sides.

And paint job done...

Unfortunatelly I missed to make pictures of the preparation for PS-2 (Red), but the result was this:

And work of today for now...the preparation for PS-1 (White):

I‘m not 100% satisfied with the result, but there are decals which hides the problem zones :)

For the upcoming 3D printed parts, one of the King Cabs mentioned in the first post is coming to me for a quick visit to check the mounting points with the transmission case for tolerances...

Very fascinating how detailed this body is, especially the front bumper area.
