The turret rotation device on the WSN T34 is the same as that on the S&S Tigers and Pershings. You may want to ask Murphy at Matotoys about obtaining HenLong Electrics. I should also inform you that the t34 requires some assembly of detail parts and does not have motor or machine gun sound effects. The sound effects simulate only the cannon and nothing else. The t34 looks gbest with a bit of mud on them!
