To be honest with you, Bob, I've only run the darn thing twice & that was in practice. Built up an M05 with every available Tamiya hop-up but then got sidetracked by my buddy RayK with running the M04 instead. That didn't work out so well for me- old dog, new tricks- so I think I will be going back to my M03 for Memphis and possibly working on figuring out the M05 during the summer. But so far...feels good.
