Those fiddly bits are… fiddly! I’ve had the exhaust fall off already and I think there are still some parts from my white kit that I need to get on there. I’m glad I have a few months to figure all that out. I will have to use the jig to make sure I am not running wider than I’m supposed to making for better running, but I am very impressed with these little cars. Maybe my driving skills are improving, but I am starting to get some better times with my March 701 with lower voltage than I was getting with my group C at higher voltage.
