It's been a while since I made an update here. I hadn't even realized that I forgot to post about my motor mount finally giving up. The design I came up with to mount it to the chassis ended up failing in the end.
I stopped running the Brushless Jato and decided not to run it again until I got a new motor mount worked out.
People at the track ask me no fewer than 3 times each week where the Jato is, heh :)
Well, I got inspired to get it running again and spent the last few days working out a new motor mount. It came from an idea that crazyjr posted about earlier in this thread. I bolted the mount to the holes in the tranny where the clutch guard comes out of. I made the mount angle upwards to the front so that I could move the battery holders further back on the chassis. End result is that I moved the motor slightly back and up, and also moved the battery holders back almost an inch.
I actually expect the mount to fail at some point since it's still the cheap aluminum I got at Home Depot, but I'm hoping to get in enough races to prove that the design works before it breaks. Once I know if the design is good, I can look at getting one machined.
Here are 3 pictures from V3:
