You are correct.

The Ti used in most R/C Car/Truck parts applications has less tensile strength than hardened Steel and more than low grade Steel.
However, because it is lighter than Steel, you can make the part(s) slightly stronger and still achieve a weight savings.

HEY ALL,

I changed my front arm sweep to one degree and my rear toe in to 2 degrees and it was definately better in some aspects, but I AM
it appears still way off the pace. I am a bit stumped. I think the cars good and the motor and battery are very good. Heck-I even think I am driving decent lines and hitting the apex's. But still I lapped a 0.9 off the fastest lap recently. And thats HUGE!!!

I need to sit down and run pack after pack soon and make one change at a time till I find the key.

What i found is the car not as smooth through transitions so I am going to change to #2 ackerman position. Maybe with the changed arm sweep-its affected the ackerman.

Awaiting more testing,
Ray

If your car is handling twitchy during transitions, maybe yous shocks are too hard?

So is that a Tobee or RC Square part??

Coz I have the Tobee part that comes with the 2 shafts and some shims. Without the spur adaptor.

Has anyone bought the front knuckles by jet or square. Is there a difference. Are the square ones that much better to justify the large price difference?

Cheers,

A better question to ask is why get aluminum knuckles at all - they're heavier and more expensive. If they bend you're out of luck and will have to go with the plastic knuckles anyway.
