Re: Wheel Layout/Attachment Design
We had external wheels this year and didn't have problems bending the 1/2" axles when we took hits but we had problems with the actual wheels themselves bending. Looking back, the wheel design could have been stronger so that wouldn't happen, but we didn't forsee the problem at the time.

Especially with a width of only 28", external wheels can give you a wider track for greater stability. Internal wheels are more protected, but the setup may weigh more and/or take up more space. I think it is all a matter of preference and design constraints placed by other subsystems. I don't think you can positively rule in favor of internal or external wheels.
