I don't think durango took off in the USA like say AE or Losi at all, but, it had a following for those who wanted a vehicle that was considered exotic and race oriented. Saw quiet a few of the 1/8 buggies (the DEX408s I think they were) when they became available. Problem was that they still had teething issues that causes guys to go elsewhere, not bad vehicles though and at the time you had a race team.
The 4x4 SCT was one heck of a vehicle, still is.

yeah its a fun truck for sure. was tempted to keep it but I needed to factor in more than just my self to support it. But its definitely fun truck.

Here are the pictures of the 210 prototype. At least, one variant of it. You can clearly see the B4 parts. I wish the saddle arrangement had stayed.

yeah, then the whole sideways shorty thing would already be in place.
Amazing to see where they were at with tech back then.

Yeah I do remember Durango mainly being in the 4WD scene when they finally came to the 2wd Scene I didn't see many Durangos at the track, they were all Serpent, AE and Losi

this thread is a life saver. been reading a ton as I'm setting this car up now. thanks again guys.
so a question regarding shocks.... as I have completed the 3gear swap and am rebuilding shocks today.
the buggy i have is used and came with extra shocks..... I measured the bodies as it looks like the shafts are identical on most of the shocks.
currently have shock bodies that are 39mm in length on the rear. shock itself is 111mm roughly
the front has shocks with a body of 32mm. and total roughly 88mm total length
I have two complete shocks that are slightly longer than the ones installed in the front. and they have a 37mm body. complete shock is 92mm. They are durango but no idea of vehicle. (dark blue stripe painted on the spring, came with light blue springs as well). should I put the larger shock body up front (37mm) and keep the rears larger (39mm)
or is increasing the shock length itself not the same as increasing the uptravel?
as for the lack of up travel..... maybe making a custom front shock tower would be ideal?

Thanks for posting that link. It looks close to what the Dex210f looks like with the standard gear box. Come full circle.
As for shock bodies.
Should be 21.5mm front bodies and
31mm rear. Longer shock bodies actually decrease up travel.
It should say at the top of the shock body what size, written on the nut part. That sounds funny..😜
Custom front shock tower would be great !!

VRP PISTONS
Are these worth getting. I am thinking of pulling the trigger!!
Also since they only offer
2x1.6
3x1.4
Which ones??
I was thinking of getting 2x1.6 and drilling one to 2x1.7 for rear.
I know JP and Travis ran 3x1.4 front and 2x1.6 rear, just seem counterintuitive. I was thinking 2x1.6 front and 3x1.4 rear as well.
Thanks for input ahead of time!!

However believe that the Durango Big Bore shocks are 12.3mm compared with 12mm for AE and TLR. I think this explains why I keep looking at SE/TLR setups and think how can they run so heavily damped when they are running 1.6x2 when I am running 1.3x6!
Does anybody else have any thoughts or comparisons to this problem?

I may be incorrect, but following some internet discussion I have derived a ratio between the weight of the oil (measured in cst) and the surface area of the holes. This has allowed me to look how the buggy is absorbing the bumps and think I need to try another 10% etc etc and also once the front back balance is there, I can adjust both front and rear to keep the ratio the same.

Good points and questions. That is what I'm trying to figure out before spending the money. What PISTONS are people finding work best for them??
With larger shocks than say AE, does that mean we can go little lighter oil than their setups in comparison?? Need more homes for similar damping??
I'm indoor with big jumps. 2x1.6/1.7 or Maybe run 3x1.4 front and drill other set to 3x1.5....

Dex210v1 has 1.3x6 which works out at 7.96mm^.
All calc using pie as 3.1415.

here is a chart Dino_D made:

As you can see 2x1.7 will have similar STATIC pack to 3x1.4 or 4x1.2 or 6x1.0.
When you move the shock shaft slowly, the differences between them is not that noticeable. However, the differences between fewer larger holes and more smaller holes is when the shock starts to pack. Less holes pack late in the stroke. More holes pack earlier due to more turbulent flow from more holes. Normally I alter pistons size and holes to adjust for track conditions. Bigger holes also favor bumpy tracks, but will bottom out more on larger jumps, smaller holes are preferred on smoother tracks with larger jumps.
I don;t have a chart referencing piston sizes (area of the holes) and oil weight combinations as there are too many different brands of oils.
Remember, oil weight is used to control the weight transfer front to back and side to side.
You can match heavier oil, and more holes or larger oils and light oil with smaller and less holes to achieve the same damping ratio, but heavier oil and larger hole area pack later in the stroke. Lighter oils and smaller hole area pack earlier in the stroke. It depends on what you want to achieve with the car.
Normally I tend to figure out what oil I want to use (heavier for fast flowing, high grip, and lighter for smaller technical tracks) and match the piston sizes and holes accordingly. Bigger holes for low grip and bumpy tracks, smaller holes for higher grip surfaces. Smaller holes for larger jumps. Just need to find the perfect balance and it takes time to test and find the right combination.
This is my opinions and testing. Feel free to experiment and try.
