My buddy Craig often asks "why?" but recoil on these tanks is a big deal to me. So I am proud to say that with a set of Pershing Electronics, repurposed parts, and a custom Rotorshield, I have made my short barrel Sherman Recoil like a champ! Elevation is not a problem, and I even got the emmitter down the barrel. I reused the Tamiya elevation arm, antenna bracket, and other stock nuts and bolts. Eureka!
