The Trumpeter 9835 is very cheap and therefore you should not expect too much also. Krumme edges when the battery compartment, ... The Trumpeter has suffered large scratches during transport. But in this sum is worth the back end of the article "by air mail" not really. Otherwise, the part has 2 speeds that do not differ very substantially. The Trumpeter's battery powered and has accordingly 'much' power to turn.
