That is not correct, they are reverse compatible. All EC3 will work on all IC3 plugs.

So glad you started a thread on the new 1.9! I love the info you provide especially in the suspension department. Glad to have you back at it.

Good eye, but completely unrelated. Or not. Things might get crazy.

What did changing the upper link buy you, theoretically?

Oh they look like the CR-01 wheels. DCW then?

Check 1st post again lol. (Wheels he squirreled away)

The upper link geo has a good explanation behind it. Its something axial continues to ignore.

The rear suspension will push the chassis forward more and up less. Highly dependent on ride height though, so adjustability is paramount.

They're an old set of DCW blems. Couldn't sell them, so I tucked them away for future use

Makes me want to get one and put AR60s and 2.2s under it.

Show us the link risers.

I still have the ones you made on my poison spyder wraith thats been rotting on a shelf.

Got some tweaks to make. Maybe later this week.

I just realized I had mixed up the EC3 with the XT60's.

My bad. Review post has been corrected.

Reverted everything back to stock while the design rework is under way so I could do some super scientific baseline testing and compare it to my DIY version. Did someone say "incline board"? No? Too bad, I used it anyway. Hit the back button now if you don't have the stomach to watch me geek out.

Weights are approximate and include batteries, tires were measured unloaded, vertical was a best 2 out of 3 on the steepest angle achieved, sidehill was measured at the point of rollover.

DIY

Weight - 6.0 lbs
Tire diameter - 4.6"
Belly height - 1.68"
Wheelbase - 12 5/8" (I cheated at Disney in 2014. Don't tell anyone.)
Vertical climb - 57.5*
Sidehill angle - 43*
Axle ratio - 3.3:1

OEM

Weight - 4.0 lbs
Tire diameter - 4.5"
Belly height - 2.0"
Wheelbase - 12 1/8"
Vertical climb - 55.7*
Sidehill angle - 43*
Axle ratio - 3.75:1

Takeaways:

The DIY has a bit of a climbing advantage due to its lower ride height, higher higher overall weight, higher unsprung weight, and slightly longer wheelbase. I got the OEM ride height as close as I could by removing all of the preload on the shocks. The OEM tires weren't quite as grippy as the PitBulls on the DIY, but not so much that it was an issue. The centers of gravity are about the same on both rigs.

Torque twist was an issue. The DIY would barely lift a tire before rollover whereas the OEM would go full twist and carry one way up in the air long before it reached its max angle. Shock, spring, and suspension tuning should help here quite a bit. Some added weight will too, but only as a last resort. I prefer to let the weight come on naturally with the mods and tune around it as much as possible, adding as little dead weight as possible.

The immediate goals are to tune the shocks and springs, get some modded XR universals installed, and see if I can sort out how to get more up travel on the front axle so it'll sit lower. Once that is all done I'll test again, get the reworked suspension parts back in, whip up some new links, and give her another go.

Yes, but there are reasons for that. Sharing parts across platforms means that compromises must be made to keep costs down. The Bomber and the Yeti didn't suffer from that issue because each had a chassis that was unique to themselves. The 2.2 Wraith chassis was unique too, but the geometry was still set up like it's SCX brethren with the Instant Center placed directly under the COG (more or less). I can't say that I like it, but I understand it.

Adding adjustability to the 2.2 was quite a bit easier than the 1.9 has been. The 2.2 had gobs of room on and around the skid, the 1.9 does not. It's very tight.

It's not bad. And honestly you can't expect it to be fine tuned to your liking straight out of the box, but I don't think that a little adjustability is too much to ask for at this point.

Getting that first 90% is easy. Fighting for the remaining 10% takes some effort.
