The wire diameter, spring diameter, spring length, and coil spacing will dictate the characteristics of the spring. Because of this, it is possible for two springs to have the same (or very close to the same) theoretical rate, yet feel different on track. I wonder if the V2 springs are just because AE had to change vendors for their springs?

I am missing the causality underlined by the bold fond
Let me try again
You can get build springs with different wire diam, spring diam, length, coil spacing and pick all these variables to get the same stiffness (K) rate, to the comma, for both.
Then - How are they feeling different on the track? What are the physics behind that difference, and what makes them behave differently beyond the simple F=KX?
I have yet to find a proper explanation on this forum. Who will rise to the challenge?
Thanks,
Paul

Looks like a bad imitation of a 22 4.0.
I've built and owned lots of AE cars and have just finished building a 22 4.0.
Blown away.
AE could at least design a car that has some origional thinking and engineering involved, like Schumacher or Hot Bodies, but then, if you're going to copy something, you might as well copy the best.
The quick access to the diff is cool, but open the diff and it looks like something out of a Tamiya Astute.
TLR's planetary gear diff is beyond comparison to the AE part.
The 4.0 ball diff is the best ball diff I've ever built and I've built lots.
Don't waste your money, just go buy a 22 4.0.

BUT...I am planning on putting my B6 up for sale and buying a B6.1 to go with my 22 4.0SR.

The spring rate (K) is only they linear force if the spring is in a steady state. It doesn't tell you many other factors that determine how the spring reacts in motion. The K value doesn't tell you anything about the mass of the spring, the hysteresis of the material, how well the spring holds its shape under compression, or how many cycles the spring can go through before it starts degrading.
Example A.
Have you seen springs advertised as low frequency? Using thicker wire and increasing the number of coils keeps the K value of the spring the same, but now the spring itself has more mass. This affects how the spring reacts to changes in direction/momentum. It might also make for a spring that doesn't bow out as much as you compress it. There is an ideal number of coils to thickness to diameter that minimizes this affect. The less the spring bows (they all do, it's a matter of how much) the less torque is placed on the shock internals.
Example B.
Many companies have switched from powder coating springs from 10 years ago to oxidizing them. This reduced the hysteresis from the powder coating, making for more consistent springs. Not saying I know the exact coating that is used on the new springs, but maybe they changed the thickness of the coating or something else to try and make the springs more consistent from batch to batch.

There's not a bad ball diff out there anymore. There are lots of people that don't know how to build or adjust them though.
#55
TLR had an issue with the male outdrives in some of the 4.0 kits. The bearing wouldn't seat far enough, and it makes it so the diff doesn't work correctly. But yeah, lots of people don't understand how to build and adjust ball diffs.

Every single gearbox topshaft on the RC10 Worlds Car re-release was defective. It can happen to anyone. Especially with everything being outsourced overseas. It's hardly a knock against the 22 4.0.

Guys, i was thinking about somthing and would like to know, whats your thought about that?
By looking at the picture of the open gear box on the AE site, when you raise, or lower those diff, you also have to move the idler gear too, so no quick change there as you have to remove and open the gear box, otherwise the opening for the out drives of inserts for the diff must been some kind of a banana shape to mach the gear mash to the idler, or do i miss something!?
I hope you understand what i mean, cause of my bad english i sometimes do not find/know the right words?

I was talking about this last night with my brother and yes you cannot just simply move it up it must go up and forward at the same time to maintain the proper gear mesh. I would assume that would be taken care of in the various inserts they give to raise or lower the diff.

Hello. I am interested in purchasing the new B6.1d for the outdoor season this summer. The tracks I race on are loose (holeshots and 3ds are common). Would the stock three gear transmission work for tracks like this or would the original b6d four gear work? Thank you.
