Hmm, interesting. Could this not be overcome with speedo punch settings. In terms of traction, in theory could you not get more with shaft? With belt drive the inertia reaction of the motor would reduce force on the rear wheels under accel, if I have got the direction of rotation correct. For cars with comparatively long thin dimensions I just think there are opportunities for big reductions in polar moment of inertia with shaft drive and shorty lipo setup as per exotek.

You are overthinking it

Tried out the ball diff in the rear this past weekend. It was a welcome feature to be able to fine tune the rear diff with a simple adjustment of a screw. I ended up with a slightly higher level of resistance than what I was running in my gear diff (1K) and was really happy with how the car drove.
During testing, I made a run with a fairly firm setting and while the car was still easy to drive the times were not on par with a looser setting.
Next up will the light weight pilot shaft and spool outdrives.

I've been a little hesitant of ordering the lightweight axles simply due to durability. I manage to stay pretty clean, off the walls and off other drivers. How fragile are these in a true race environment? The most common contact at our track is someone coming in too hot into a corner and tapping the inside rear of the car. The contact is usually pretty minor. Would this little amount of contact likely fracture the lightweight axles?
