Hi Bat!
Yes, Rodney has run the "leaner car" several times. He brought it up here after he got it and we updated the roll cage to get it "legal" again (rules had changed a bit since you built it). He removed the derailleur to simplify the drive train and modified the motor mount to accept an Etek motor. He took it to Pensacola and up to the big race in Alabama a couple times and had a couple of decent results. He is still tinkering and experimenting with it, but it's one of six Electrathon cars he has, so he spreads his time around on all of them.
