I haven't noticed this problem with our .5 inch dead axle robot> But on the cart was made from the kit-frame, the axles are severely deformed and bent. this was also a problem on our 2009 prototype. In a year like logomotion, this may not be an issue, in a year like breakaway, where every time a robot came off the bump the axle took the shock in the same way, I think it could definitely contribute to some bending.

But if we're comparing WCD to dead axle set ups then the fact that the shaft is unsupported more than accounts for any problems caused by multiple shocks in the same place. Bottom line, your axle shouldn't ever be bending, don't rely on an equal distribution of bends to keep your axles straight.
