Szczerba’s 2019 Comp Sportsman “Enigma” Build

[Szczerba]

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.

Transmission and motor final installed.

Rear axle spinning faster than the front?

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?

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

I'd have to measure the pin to pin.

I was hastily hand hacking carbon fiber comp rigs back in 2011 !
Szczerba's FF-SZ 2.2s

[Szczerba]

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

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

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

[Szczerba]

Foams and tires.

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

Crawler Innovations 5.5 and 6.0 double deuce comp cut narrow inners

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.

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

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.

RTR minus body




Yup, rear camber

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

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...

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

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.

Itll never work - its just a fad

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.

[JatoTheRipper]

Bad ass build!

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