Many expensive aluminum parts I believe it is valuable due to the many options included. It is an old item, and there are characters written on the back of the chassis. Due to circumstances, I will ship it with a genuine Kyosho servo instead of the Chinese servo shown in the image. It is likely an electric conversion. I intended to install the electronics, operate it, and replace the servo saver area, but I gave up because it was too much trouble. Therefore, the parts around the servo saver are detached. There are not many scratches on the back, but there is rust and scratches. Please purchase only if you can adhere to the following conditions. Agents do not need to adhere to these. - Strict adherence to the receipt evaluation on the arrival date. - Do not give a bad rating for reasons such as "it's different from what I expected." - Purchase only if you are not overly sensitive and will not complain about the condition of the product.
