IF you want a good runner with high durability and dependability a HL is not the best route. Tamiya is the most durable and dependable. The KT idlers are not a big deal to upgrade. Daryl tuner has fine upgrade and home made ones are cheep and easy to do. The KT It is a very durable tank but very big. The best Tamiya tank are the M26 or Panther G. Sell that KT id you like and get the tank that will NEVER disappoint you. Taigen is the best of the toy tanks...Tamiya is still in its own class a fine RC model. Although the margin is narrowing. How do you want to use it just to drive or for IR battle. Good Luck, Bob
