I just saw the Firecat, Rev and RX-1 in person for the first time in the past week. They all have similar front ends with a small bulkhead sections and long A-arms. My question is, the A-arms all look pretty vulnerable to me. Does anyone else see this as being a problem? Man, all I can think of is a rock, bump, or stump catching a hold of one of them things. I have a ZR and it seems to me it has a wider bulkhead and that the A-arms are a little better protected.
