Hello!
I got the upgrade kit, and it works fine. The Tiger is able to move very slow and very fast. The speed is varyable as schutzstaffel wrote.
I have only one question: whereto should I connect the wire of the led of machine-gun.
I made some pictures from the reciver board. Please, someone designate the points, whereto I should blowe on the wires.
