I have 6 shorties in my arsenal. I have 2 Hobby People, 2 Turnigy A Spec, and 2 Trakpowers. I actually prefer the A specs over the others. Great punch and decent power hold during a main. The Trakpowers hold longer but lack the punch feel the Turnigy's have. I use th HP and Trakpower's for practice and A specs for racing.
