These front portal covers/weights/weight holders are very nice.

Glad to see you sharing this build on rcc.
Do you have more information about transmission?
Reminds me of my scx10 ii Cherokee transmission.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Pretty snazzy! List what parts they are!

Yo, when are you going to buy a vendor star and pimp all these cool products you are making?

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

I'm not into comp crawlers, but this thing just looks sick already!

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Some fun looking parts for this one, i'm curious about what the ratio is on that transmission.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

I am in the process of cutting axle shafts and doing mock up installs. I will tear down and take pictures during final assembly.

Will do


:ror:

It is some pretty cool progression for a comp rig. I can't wait to get it finished. Should be able to knock alot out this weekend.

I'll have to check on all the ratios, actually.

"thumbsup""thumbsup"

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Axle shafts built and axles built. Final axle tear down and assembly is next.

Hi,

Could you show how it's inside portals and transmission ?

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

I would like to know more about the transmission as well.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Looks like it’s all “high altitude performance” parts

Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Had to cut axle shafts and do axle assembly first. I will take apart the transmission soon.

Correct, except axle shafts, gears and c-hubs type parts.

First picture of the thread shows those parts only.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Gonna have to get one now. But what colors....

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

ive seen the prototype rig run a line on FB. nice color choice you got there Shane. the axles are giving me ideas for my sporty losi build.. I have to finish my super first though.

Transmission pictures.
Cam style motor mount.

Well thought out and practical.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Looks sexy on there! I’ll send another color if you don’t like the red motor hoods contrasting the red tranny. Matching reds can be tough

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

No biggie on the colors. Close enough for me, as the shapeways red varied from the color sample on the website to begin with. I grabbed this 16x 500 for intial testing on 4s for this build. I think my last shafty comp motor was a spicy 400. :mrgreen:

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

I wonder what the final gear reduction is from the pinion say a 18t to the final portal gear is on these rigs..

I am willing to bet a reversed gear portal losi axle setup would work really well with his trans setup.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

With a 12t pinion on the motor, the transmission is 7.25:1.

With current portal gears.
Front axle is 7.72:1
Rear axle is 6.51:1

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Got the rear axle final assembled.
Rear has some negative camber built into the lockouts, so uni’s it is.
I have regular portal box covers but leaving these weight holders on for now, in case rear weight is needed.

Rear axle spinning faster than the front?

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

I hope not! I must have mixed the numbers up.

Looks good on them shocks and shoes. Hint hint.

was TT factored in on the side the driveshafts were choosen to be on?
awesome trans.


what pin to pin measurement is your axle width closest to on an axial rig? SCX? XR? AR60?


TSS building on road racers, and Shane building carbon fiber comp rigs.
the demise of RCC is here:mrgreen:

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Everything was "factored" into this rig. For example, there are only two adjustment points on the axle upper links. "thumbsup"

I'd have to measure the pin to pin.

I was hastily hand hacking carbon fiber comp rigs back in 2011 !

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

These are 9.3” pin to pin and AR60’s are 9.65” pin to pin.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Great build. How much was the setup from high altitude performance? Also, how did you narrow the axle shafts (what tools did you use?)?

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Thanks. Just some calipers and a dremel to cut the shaft to length and to grind the flats.

Narrowed Ottsix Voodoo Gold Pins. Narrowed up a pair of silvers too.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Cool build looking good!

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Thanks. Been doing some testing and tuning, as well as waiting on a few final parts to arrive. Then I can mount the body and start really testing and tuning.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

After you mentioned this today I had to check in on the progress. Loving it so far.

Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Thanks! A little slow going in the garage and heavy rain last week so kept me off the rocks.

Got to the final wiring tonight. Not the cleanest but good enough.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Very cool build! Excited to see some video of this beast. "thumbsup"

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

I really like this project!
I'm curious about the rear camber, but it's different, and I like that.

The only thing I'm not such a fan of is how wide the chassis is...

Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Honing in the perfect setup every evening, one 650mah pack at a time. :ror:





Rear camber is for sidehill and uphill turning stability.



All of the components were/are thought out and have a purpose. The chassis is "wide" to get the upper links close to perpendicular to the axle mounting points without having to add mega spacers (weak point) at the chassis. Also, it relates to shock positioning at the chassis and the axles.



So, that translates into a car that needs very little tuning (compared to a setup with multiple tuning points) when it's bolted together and ready to run. It has two adjustment points on the upper links at the axle and an 1" or so adjustment at the chassis. Paired with the link/shock locations already designed to be "close" to great. Although, some may not like this chassis setup for their driving style, it is car that works super good with little previous knowledge of car setup. Just my $0.02. I haven't built a custom sporty comp crawler since 2012 and this car jumped me right to where I was in 2012 without the hours of hand cutting chassis and other components.

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Itll never work - its just a fad :mrgreen::mrgreen::ror:

3D printing has def opened up a lot of options and Casey is finding them for sure. Nice seeing a veteran dabble in the comp side again. "thumbsup"

Re: Szczerba’s 2019 Comp Sportsman “Enigma” Build
 

Bad ass build!

You call it Enigma, but I think it's (Red)onkulous!
