"Missed it by ... "That Much" ... " (maxwell smart)

Of course, after a good first round my tires decided to break their glue, with symptoms such as jack-rabbit hops in the back straight (when the wheels would spin inside the tire, then finally grab the bead and hence flip the car).
After several frustrating experiments with freshly glued and trued tires; it became obvious that for my set-up a trued 19mm outside diameter tire is optimal. Any tires larger than 19.5mm in diameter make the car want to roll like an armadillo in the "button" curve, esp. in Green.

A low Center-of-Gravity (CG) is very important in All cars - but especially for these skinny-track cars. Even though the Fly bodies seem to be made of the same plastic as other brands, and seem to be as thin (certainly thinner than Scalextric and most Pioneer/Revell) it seems they are a few grams top-heavy, thus making cornering very challenging (esp. using OEM stock chassis). Another contributor is the shape of most of the coupe bodies, with mass peaking a little back of the center of the wheelbase (encouraging rolls and slides from the JLO shape).

Offset motor pods help, as well as small diameter tires, Lexan cockpits, and 3DP chassis.
