Thanks!
(this doesn't mean I will look to upgrade, I just heard the materials may be better now)...

More and more Mod drivers are going to 3 gear. And a change to a 4 gear is cheap compared to all the stuff you get in the lite kit.

I posted a video on another post debating mm3 vs mm4 but it didn't seem to catch on.
This is what I wrote if it can be of any interest to somebody here as it was done on my b5m:

"I'd say it's negligible.(about mm3 vs mm4)
Sorry I just did this video for your question. The quality is crap and it's loud (turn the volume down a bit for the squeal of the motor):
https://www.youtube.com/watch?v=DATXwtVJoSY
The car is on water not touching anything else. The test speaks for itself.
I tried several axis. I can feel resistance (very light) on the vertical axis with no rotation direction preference but pretty much none one the other two.
Certainly no movements on it's own. So changing direction shouldn't make any odds or to me at least it's negligible.

I'm open to any theory/counter theory as I once contemplated the idea too."

You want a sub-forum for B5m plastics discussion?

That just wasted a minute of my life that I cannot get back.

May not have caught on because the video doesn't show anything. %99.9 of what torques the car/chassis forward or rearward, is the rotation mass of the drive wheels, inserts, and tires tires. Since you did this test with them removed, you might as well have done nothing at all.

(oh p.s... you need a new antenna tube)

Your video does nothing....put some tires on it and try it again.

I think that was the point he was trying to make. If you remove the tires from the equation the rest of the rotation of the drive train makes next to no difference.

He was trying to say that 3 and 4 gear made little to no difference but then he tested it without one of the critical items of the equation. Making this experiment useless.

The tires go the same direction with a 3 gear as they do with 4 gear, but the debate is what effect motor rotation has on the cars attitude. It seems that you would need to have the tires off to test for those effects.

Would be simpler to do the same setup on a flat surface with the camera showing the shock action/chassis attitude change.
