Thanks guys. I ran a couple packs last night. Here's what I learned.
One lipo pack is not enough to keep up with the current demands of the 7XL motor. The pack hit 150 degrees hot. No puffing of the pack, but I was definitely freaked out from the heat. So I'm going to run a second pack from now on. I found out for myself that lipo packs can keep a steady current but when they dump it's like a light switch. One minute it's going full speed and then it's barely crawling when the voltage drops. As for the super glue I put on the motor, it held up after running back to back packs (20 minutes) in the parking lot. Don't know if it would hold up offroad. I don't feel like trying that until I get the motor clamped tight. After each pack, the ESC temps were between 95-110 degrees. Motor was 146-150 degrees, which tells me I'm in the ballpark in terms of gearing. Even though the ESC box works, I'm still going to tinker with the internal foam blocks and work on a new mounting location. Also the GRP tractor tires do not do well on pavement. This may explain why the truck keeps stepping sideways when I jam on the throttle.
Some crappy video. All you can really see are the lights.

Looking forward to running two packs and seeing what she can really do.
