Just finnished my b44.2 build. I've built two Durango cars/trucks and it was sure nice to finally build a kit that had all the parts included. AE quality control is an A+. The build was easy and all parts meshed perfectly. I'm running a Tekin RS Pro with a Reedy 7.5. I'm using a basic box set up with a few minor tweaks that i feel are appropriate for my track.
Can't wait to run this thing, everything looks solid. As for the ball cups...i'll most likely go to RPM as well...eventually.
